    Mike,
    How many quarts do I need to replace
    the oil in all of the manual transmission
    elements? I know there is a separate front
    and rear differential, but what about the
    gear box?
    Thanks

    The front diff and gearbox share the same oil. All that information along with the correct quantities are conveniently located in your owner's manual.

    Well... I finally made the switch!
    After much debate, and with the help of all of you guys out there, I decided to make the change to Mobil 1 at the 6,000 mile oil change. I went with 10W-30.
    After a few short drives, boy, I am glad I did. The sound the turbo makes when it kicks in is even better then before. I guess it is true that the turbo spinning just "loves" synthetic oil. It seemed to have even more authority than before.
    Another noteworthy point is how fast the oil pours from the container. In New York (Long Island), the weather is a bit cooler than last week, around 50F, and it flowed in less than 1/2 the time of regular dino oil.
    Wish me luck over the next ten years or so... and that no seal leaks develop. With the performance of the Mobil 1 in my WRX, I do think it is worth taking the remote of a future leak! Heck, I'd rather replace a gasket or two down the road than rebuild then engine anyway.

    For everyday driving, it probably doesn't make that much difference if you're using the right weight for the temperature and change your oil regularly. I used dino 5w30 for the first change at 3k miles then switched to Mobil 1 5w30 at 6k miles and never needed to add oil between changes. Since synthetic flows better when cold and is more heat resistant, it might be a little easier on the turbo bearings so I figured it might be cheap turbo insurance. Using synthetic for the gearbox is a bit riskier proposition. There have been mixed reports about this. The OEM tranny oil seems to do just fine. There has been no grinding and shifts are smooth even during winter. There is also the risk the dealer might top off your synthetic tranny oil with OEM stuff without your knowledge. The owners manual warns about mixing tranny oils, so be sure to let them know if you've switched.

    Talked to a Subie master mechanic this morning and he said that using the synthetic in your gearbox can contribute to gear grinding if you are at a stop and put the stick from neutral into first too suddenly. This is because the synthetic lubricant is more slippery and doesn’t stick to the gears as well when you come to a stop. He also said the problem can get worse in warm weather, because the synthetic thins out and drains away from the gears even faster, so you can get metal to metal contact—obviously not a very desirable situation-- unless you are very careful to always ease gently into first when at a stop.
    He does however recommend synthetic motor oil for the engine as it will make your engine last a lot longer, but says you are just as well off with the regular OEM gear oil when it comes to long life for the tranny.

    But you need to "mix" a little cocktail. Pure synthetic will ruin the synchros and cause you to grind more gears than a M4A4 Sherman Main Battle Tank ever did. I'm attempting to locate the name of the stuff to add as well as the mixture ratio. I'll be back...
  • mikenkmikenk Member Posts: 281
    Again, on the advice of my dealer, I went with synthetic and it shifts smoother and no grinding at all. I guess I should have been a Sherman tank driver.

    We have Mobil 1 synthetic in the gearboxes on both our Forester and WRX. There is never any problem shifting or downshifting once the cars get rolling, but on a warm day sitting at a stop light, I sometimes can grind the gears going into first too fast from neutral when the light turns. I'm positive the clutch is fully pushed in when this happens, which is why I called the dealer. Neither car did this before with the regular OEM tranny oil. Anyone else had this experience?-- it would be good to get some more feedback on this problem--or are my shifting reflexes just too fast for my own good? :)

    P.S. Personally, I would like to continue using the synthetic because I believe it does reduce gear friction and gives you faster shifts, but don't want to use it at the cost of continued gear grinding. Any more suggestions or thoughts on this would be very helpful. The "cocktail" additive sounds intriguing.

    Hi all,

    Does anyone know a good conditioner for the rubber molding that seals around the windows? I can already foresee this stuff drying and falling apart without maintenance.

    Thanks,

    rexaroo - It is common for Mobil 1 to grind in Subaru gearboxes. Check out the Transmission Forum on i-club.com. You will get a wide variety of opinons though. Some people never get grinding with Mobil1. I use Amsoil standard synthetic 75W90 and have never had a problem with grinding.
    Last night at an i-club meet there were two guys with the same model year RS. One had been running the same Amsoil that I have with no problems and another was getting grinding with it.

    This is from the STi mailing list archives, posted by the Subaru Tuner RalliSpec:
    "The only difference between Mobil1 synthetic gear lube and Mobil SHC (also synthetic) is the lack of friction modifiers in Mobil SHC (preferred for Subaru tranny).
    Mobil SHC from what I understand is an industrial product and thus packaged for industry and not easily obtainable. We carry this fluid but get in 5-gal containers direct from the distributor... "

    aric - Treat the rubber seals by spraying silicone on a rag and wiping the seals. Don't spray the seals directly because the aerosol propellants could dry out the seals.

    That i-club thread is very interesting to say the least. Trying all those different brands to find a synthetic that works could get mighty expensive after awhile!! Looks like the easiest solution is just to go back to the dino tranny oil--no problems there--although doing that, we'd be giving up the performance advantage of having a synthetic. The Mobil SHC looks like the best synthetic to use but might be a little hard to find. I'll just stick with the regular Mobil 1 for now and try to keep my ham-fisted driving to a minimum :)

    Can anyone recommend an aftermarket exhaust system for my wrx 5 speed? I bought the car, so i plan on modifying it down the road. However, for the next few years, I will only add simple things like exhaust and suspension and do an ecu upgrade later. I am looking for a bit more power, but am really more interested in adding a little more sound for the car. I find it too quiet for the type of car the wrx is and would like a more raucous sound. I know that cobb has a simple cat-back system and borla has one available too.
  • rexaroorexaroo Member Posts: 174
    In the June issue of Sport Compact Car just out, they review 3 sport exhausts in a special feature on upgrading the WRX. This month, they do a 41-hp performance upgrade using the Vishnu Stage 0 kit
    and picked the Supersprint Race exhaust which adds another 10 hp. Pretty good reading--next month they'll do a brake upgrade.

    More on synthetic tranny oil: according to the service dept. at John Elway Subaru here in Denver, Subaru does not recommend any type of synthetic gear lubricant whatsoever--just the regular OEM. Looks like we'll be switching back to the regular in our Forester, although might try the Quaker State synthetic in the WRX because no problems have been reported on that one. Will report back in a few months on the results if we go that route.
  • bluesubiebluesubie Member Posts: 3,497
    What's most interesting in that Project WRX article IMO, is the change in h.p. after an ECU reset.

    The car had just seen a few hundred fast and hard driven miles. First it dyno'd at 177 hp (at the wheels) and with an ECU reset, the car lost 10 h.p. The ECU definitely adjusted to the hard driving they were doing.

    Well it looks like I've fallen victim to the CEL problem that was posted a while ago. This coming Wed will be the 3rd time my WRX has seen a dealer in 4 weeks for it. They are claiming that I'm not tightening the gas cap enough, but something tells me that 3 full turns while clicking should be more than enough to seal it. Did any of you guys finally get this issue resolved and if so, how?

    well, my salesman drove down to another dealership today to do a dealer exchange for me. i wanted the wrx wagon in silver with automatic (normally i would have gotten the 5-speed, but the wife doesn't do stick shift).

    i'm paying $23,450 before taxes. can't wait to drive it. i told my salesman to be gentle with it while he drove it up from the other dealership.

    i don't think it came with the auto dimming rearview mirror and compass or the extended armrest. are these things i can have installed or are they factory installed?
  • lilbluewgn02lilbluewgn02 Member Posts: 1,089
    You can have them installed, or better yet, buy them yourself from subaruwrxparts.com and do the install..it is supposed to be easy.
  • hunter001hunter001 Member Posts: 851
    Congrats on your purchase.

    If it is possible, then I would suggest that you drive the car back yourself, rather than letting the salesman do it.

    According to our Subie advisor, CELs frequently appear during the winter months if your region switches to oxygenated fuel. Also, on the WRX, it helps to always buy your gas from the best-known oil companies. Amoco and Phillips 66 are very trustworthy here where we live. Some of the off-brands allow water contamination to get into their fuel tanks and can cause misfires that set off a CEL.
    The one time our CEL came on was after buying a tank of gas from one of the lesser known brands. The light eventually went away after about a tank and a half of our usual Amoco 91 oct. Another tip: buy your gas from a newer service station with spanking clean tanks, instead of an older station that might have old, corroded tanks--this can help prevent getting contaminated gas.

    Well, I bought my 1st new car--a killer black WRX sedan. I have to admit that I'm very new to learning about cars, but my enthusiasm for the WRX has me reading and talking to folks who know day and night, and my learning curve is steep. However, I've made two (in my opinion) pretty big mistakes out of ignorance. I am hoping someone on here will help me realize the magnitude of my mistakes:
    1) The car had 250 miles on it when I got it becasue to get the exact car I wanted they had to dealer trade with a dearler 220 miles away.
    2) I have had the car above 4000 rpm probably about 5 times (max 5500) and for just a few seconds. I did "race" it once off a stoplight (before I read the owner's manual and this site).
    Now I know a few of you are going to want to cause me bodily harm for this, but what I am looking for are some HONEST answers about the gravity of these mistakes. What should I be looking for that may tell me I've damaged the car (or is it more of a long-term damage that will present subtely). And is there anything I can do now (at 400 miles) to reverse the errors of my youth? I do plan to wait out the last 600 miles of my break in, thats a start I suppose.
  • wrxguywrxguy Member Posts: 51
    1.First things is to just continue with your break in and stay within(below) the 4K range and ideally dont stay at same speeds Rpm range(too long) while driving on the freeways and such.

    2.Don't beat your self up. A few seconds at 5000 rpms probably didnt do a thing. You may hear some conservative speculations that you did some irrepairable damage but I highly doubt it.

    Is the oil dark beacause of excess work/friction? I doubt it. Its all about heat and friction over time. Break in periods are ideals some follow them perfectly I went over 4k once too. Some guys wait until 1500 or 2000. opinions vary..enjoy and learn not everyone is not an expert!
  • pete104pete104 Member Posts: 4
    Anyone out there bought the short throw shifter from STI or other. Thinking of it, just wondered how it works?
  • cptpltcptplt Member Posts: 1,075
    a Subaru senior master tech I know says the 4K rev limit is total BS as long as you aren't trying to kill the engine or revving it stationary. If its pulling the car and you are driving "sensibly", getting even close to redline with a new Subaru engine should not be a problem in terms of any immediate or long term damage. Of course if your engine blows up in the first 1000 miles if you do this, SOA will probably take that as an excuse to not cover under warranty!

    There was just a nasty storm and my car was caught in the parking lot of the local Target.

    It hailed.

    I come out, the hood is basically destroyed, the roof has about 30 dents in it, and I have one dent on the trunklid.

    I was parked next to a freakin Cavilar with NO damage on it.

    The other side was a Hyundai, ALSO with no damage on it.

    I couldn't see damage on any other car in the lot, yet mine looked like someone went to town on it with a hammer. WHY does something like this happen on a $25k car when $12k cars come though with zero damage.

    I love my car, a lot, but this one incident has me serisouly considering ditching it. Sure the crash tests are good, but if it can't survive one small hail storm without MAJOR damage, I'm a little skeptical of it's long term reliability.

    In short, Subaru let me down today, let me down so much that I may never buy another.
  • cptpltcptplt Member Posts: 1,075
    dunno about your roof and trunk though!
    Not sure what hail tolerance has to do with reliability.
  • bull3964bull3964 Member Posts: 65
    It has to do with a car that doesn't look like [non-permissible content removed] before I have a chance to pay it off. I guess reliability was the wrong term, but I think you get my point.

    It seems like this car gets damaged if someone looks at it sternly. Hell, I have stone chips on the BACK of my car. Mechanically and structurely, it's built like a tank, but it doesn't seem to be able to maintain it's appearance worth a damn. I've worked hard to keep this car in good shape in the 5 months that i've owned it, but it seems to be an uphill battle that I can't win.
  • hunter001hunter001 Member Posts: 851
    Basically, there is no point in worrying over things that you have no control over. Now the deed is done. So make sure that you take care of it in the future. About you having taken the car to a higher RPM once or so, it probably saw a sustained high rpm run in the first 250 miles of its life. So that is something that would make no difference now.

    About the comment about "subaru master technicians" and such fellows offering advice contrary to what was suggested by Subaru design engineers (present in the owner's manual), I would disregard such "advice" and follow the written advice provided by the folks who designed the car. "Master technicians" or any such similar fellows can take a hike.

    Just my 2c.

  • cptpltcptplt Member Posts: 1,075
    Its not just some self proclaimed moniker, its a paper certification Subaru themselves give to techs who earn it by going on the appropriate courses and there are not very many Senior Master Techs, most dealerships have at best a Master tech and some I know in the Chicago area have no master techs 'cause they pay their techs so badly they could never keep a master tech!
    I agree wholeheartedly with you that one should follow the manufacturers instructions but there are undoubtedly times they side on the very conservative because there are people out there who aren't sensible. Like the law, sometimes you have to protect the public (or your corporate liabilty) from the lowest common denominator! But for sure, having it go over 4K for a few seconds is not going to do anything. Trying to do 0-60 in 6 and redlining all the time in the first few hundred miles is obviously another matter!
    This reminds me of when I picked up the wifes BMW in Munich when we were living in Europe in the 80s. How the heck does one get from Germany back to England on the autobahn and not go over 3500 revs. Just keeping up with the trucks at 5th gear put us over! Well, the car lasted close to 10 years with no engine problems (the ECU was another matter - replaced yearly for almost 5 years!) but I was a little paranoid for a while! Yes, obey the "manual" put don't go crazy worrying about it as long as you haven't been driving like someone in the WRC!
  • bull3964bull3964 Member Posts: 65
    Hail smaller than golfballs did this damage. In fact, most of the pieces I saw were smaller than a jawbreaker.

    http://home.attbi.com/~amremai/hail2.jpg


    I also find it odd that the damage was 100% only on the roof, hood, and trunk. I mean the fenders are flaired so they have horizontal surfaces and there was no damage on them.



    There are also the strips of roof outside of the black plastic tracks, they were also undamaged.


    Ironically, the lone dent on the trunk was UNDER the spoiler.

    And I repeat, no other car in the lot appeared to be damaged.

    I test drove a WRX 5 speed sedan yesterday and was very impressed. I'm not in the market for a new car right now, but I have been curious about the WRX since it's introduction.

    A few comments:

    The one I drove had a short throw shifter (which was great, BTW) and a boost gauge on the steering column. The factory sticker listed these as seperate options (not parts of a package). Edmunds shows the shifter as part of a package.

    I asked the salesman if you can factory order a WRX without the rear wing, and he said they all come with the spoiler, even factory orders. Personally, I think the WRX is perfect without any options...except the shifter, which was great!

    Congrats to you owners, I'm very jealous. It's a modern day Datsun 510, and I would love to own one!
  • tenchijintenchijin Member Posts: 16
    When those manuals are written, they're written for the dumbest logs on the planet.

    As such, the break in is set VERY conservatively. It has to be. Human nature being what it is, the majority of people will not heed the advice, out of laziness or "aw, it won't hurt this once".

    It has a built-in degree of lattitude to ensure that people can slack off and still maintain reliable engine life.

    In short, just be mellow, and don't worry too much about it. Follow the instructions as best you can from now on. You should be fine.

    fedlawman:

    The short throw shifter is not part of the package - it is about a $300+ option. Most people seem to like the normal shifter just fine. Also, the sedan comes standard w/out the wing. I believe the wing is port installed.
  • barresa62barresa62 Member Posts: 1,379
    standard w/the rear wing? I'm pretty sure it is a port-installed option for the Stateside models ( std in Canada though). I know that SOA decided that the rear wing would be std on the limited run of yellow sedans.

    Stephen
  • fedlawmanfedlawman Member Posts: 3,118
    I'm sure it was a line from the salesman. He told me the story of a poor soul that factory ordered a WRX without the wing, and after 30 weeks of waiting, his car finally arrived...with a wing.

    Probably just the salesman's way of trying to convince to buy one off the lot.
  • ateixeiraateixeira Member Posts: 72,587
    Hail damage is a bummer, at least your insurance ought to cover that.

    I believe Kia and Hyundai use thicker sheet metal, but that's why their cars tend to be heavy. C&D has an interesting tidbit about the Sedona, and why it's 700 lbs heavier than some bigger vans.

    The explanation is simple, though, it's Murphy's Law at work. All hail falls on the nicest car on the lot. ;-)

    -juice
  • paisanpaisan Member Posts: 21,181
    I didn't read the C&D article but I heard it was cause it didn't pass safety specs for the US w/o being beefed up and the cheapest/quickest way to beef up safety is just throw in more steel. I like the sedona personally.

    -mike
  • ateixeiraateixeira Member Posts: 72,587
    I test drove one and still liked it. Don't knock it 'til you try it, you'd be surprised. :-)

    C&D showed how lots of underbody parts are beefy and they use steel in many places where competitors use aluminum.

    What bothers me about it is the 5mph impacts IIHS did made the air bags go off! Dial down the sensitivity guys!

    Hmm, how to get back on topic...can you imagine smacking a WRX turbo on that engine? :-)

  • paisanpaisan Member Posts: 21,181
    would probably reduce the HP cause it would restrict the exhaust too much, no?

    Hi all, I'm thinking a lot about selling my 2000 accord coupe and getting a wrx wagon in the near future. test-drove a sedan this weekend and it was great, but have been reading edmunds and i-club boards, and there are two issues which are somewhat turning me off, can anyone comment on their experiences?

    - abs brakes: lot of people seem to be having problems when hitting bumps, and the issue does not seem to be resolved yet..
    - clutch: lot of people seem to be having problems with their clutches making a lot of nasty grinding noises when downshifting to high rpms.. not very inspiring to hear this to an accord owner who loves to downshift into vtec range and hear nothing but that engine rev (I did downshift the tester a couple of times, and didn't really notice anything except that cool turbo whine though)

    I think the brakes thing really unnerves me more than the clutch issues... any thoughts?

    thanks,
    hys
  • paisanpaisan Member Posts: 21,181
    clutch: The posts you see on i-club are from people who are shifting into 1st gear at like 25-30mph, then they wonder why their synchros and gears are fried.

    abs: some people have experienced problems although it is in very very rare occassions and hard to duplicate, most feel it is not an issue really.

    On a side note make sure to take everything you read on I-club with a big grain of salt. I've been on there since the beginning (member # 197) and there are a lot of kids on there that don't give the whole story when they post up.

  • rexaroorexaroo Member Posts: 174
    We have 5700 mi. on our silver WRX 5-spd. wagon and yes there is something quirky about the ABS.
    I've noticed it on two occasions when braking over very lumpy surfaces like really bad pavement or railroad tracks--it's like the ABS comes on, but you're still floating over the road surface without really stopping. Happens only briefly tho and the brakes do take hold after a couple seconds. On a scale of 1-10, I'd rate it a 3 for seriousness because no harm actually comes of it (so far, anyway, knock-on-wood). For normal everday driving, there's never a problem stopping.
    As far as the clutch is concerned, I agree, it's all in whether you baby or abuse the transmission in your driving habits. If you shy away from clutch-frying stop-light duels and enjoy the Rex as the superb open road car it was intended to be, you shouldn't have any problems.
  • barresa62barresa62 Member Posts: 1,379
    having switched to 17"tires/wheels I have yet to duplicate the same low speed/over rough roadway/no brakes briefly sensation as when I had the stock 16"wheels/tires. For that reason alone (after having experienced the ABS BS) I would recommend upgrading to 17"wheels/tires. Just my .02

    Stephen
  • cptpltcptplt Member Posts: 1,075
    either on iclub or wrxnet someone had a pretty good explanation (for the mechanically challenged like me) for the problem which seems to be more a suspension problem than a direct ABS one, tire hits bump, goes into air, strut does not extend down quickly enough, ABS thinks airborne tire has locked so no braking.
    anyway, so my question is, anyone got fancy shocks out there and has that solved the problem if they had it with stock shocks. I think I've experienced it twice but was unable to replicate it though I tried several times - got a funny look from the cop hiding at the corner by the railtracks I was trying this at!
    get my 17 in wheels and S03s later in the week!
  • paisanpaisan Member Posts: 21,181
    I have to agree with the shocks and/or tires evaluation. I had a very very similar problem on washboard surfaces with my Trooper, known for it's hydrolic shocks and so-so tires. After upgrading to gas-charged shocks and later to better All-terrain tires, the problem is gone. It was exactly as described by others on their WRX.

  • gotwrxgotwrx Member Posts: 52
    unless it gets heavy use (dusty, lots of stop and go, towing etc) then 3250/3mos. This is pretty standard for most cars I think.

    General advice is to change on the more frequent schedule if you have fun with the car. You will. You can't help it. At least I can't.

    5000 is probably a good compromise for most purposes. Easier to remember which might the the most important thing.

    You can use synthetic and go with the 7500/6mos schedule. Advice here is to change over sooner rather than later and stay switched. Opinions vary on the real benefit of this. I haven't decided.

    First off, i've calmed down about the car. I bet the reason why didn't see damage on other cars is mainly because of the water on them.

    Anyways, just met with my insurance adjuster. They are going to replace the hood (which makes me very very happy) and alotted quite a bit of time for the repair of the roof and trunk.

    My offical count yesterday after I washed the car.

    27 - hood
    18 - roof
    3 - trunk
