    Our local AutoZone sells both Mobil 1 0W-40 and Castrol Syntec 0W-30 for less than $6.00 per quart. Both oils are significantly more robust compared to the oil you just bought because not only do they meet the 502.00 gasoline oil spec, they surpass it by meeting the VW 503.01 spec. FWIW, 505.00 is for Diesel engines, and both of the two oils I mentioned are certified to meet that spec as well.

    FWIW, the Mobil 1 oil can also be found at our local Walmart as well as many of our local NAPA dealers.

  • I have a 2001 Passat 1.8t with an oil pressure / sludge problem, so I was browsing these posts. I found this post that might help with the transmission problem... http://forums.fourtitude.com/zerothread?id=3471982
    I hope this helps..

    As for my oil pressure / sludge problem I have chosen to try the Auto-RX cleaning procedure. http://www.auto-rx.com/pages/heavy_sludge_app.html

    FWIW... This oil pressure / sludge problem has manifested itself in a cam chain tensioner indicator code in the computer and a dash oil light on a few occaisions. VW wants to replace the Cam Chain Tensioner, a $900 repair. I figure the Auto-RX solution (about a $60 endeavor) was worth a try.

    While you're not going to lose much by giving the Auto-RX a try, I seriously doubt that that stuff will even put a dent in your sludging problem. Assuming that you get little or no benefit from the treatment, your best and cheapest remediation measure might be to have the cylinder head, oil pan, and oil pickup pulled and cleaned. With those our of the way, you have a pretty good chance of keeping your engie running for quite some time yet (assuming that you use a good VW approved oil and change it OFTEN).

    Keep us posted.

    I have a 2003 VW Passat, 1.8 liter turbo. I got a low oil warning ("Low Oil Pressure: Stop Now"). Anyway, my car has 95,000 miles on it and it is 5 years old.. still VW fixed the "slug" issue for free.

    I was told that the the VW 1.8 turbo's heat will slug the oil as there is no after oil cooler; moreover, the oil pan is too small to allow for adequate heat dissipation. The best prevention: don't skimp on non-synthetic oil (use recommended oil--see manual) and have the dealer run a cleaning/deslug procedure ever 20,000 miles (about $100). The synthetic oil should be changed at 7,000 or when it gets dirty looking (dark), which ever occurs first (my experience is about 5,000 or 6,000 miles).

    The fix: The dealer checked for cam and crank wear, saw none... and cleaned/replaced the oil pump pick up screen. Then ran some sort of approved solvent/oil mixture through the engine to clean it and changed the oil twice. The total bill was about $650, but VW's warrantee took care of the bill.

    I believe it is well worth the effort to keep the engine running clean and correctly. Afterall it is a well performing vehicle, otherwise. Also, note that the mechanic said that the engine has such low tolerances that it is best to use the oil specified to ensure low engine wear and problems. Do not use cheep oil, for your own good.

    I'm not sure where you get your information from, but 7,000 miles in a 1.8T, even on the best synthetic oil, is waaaay too far. Per your manual, 5,000 miles is the maximum oil change interval, and not just any synthetic oil will do as only oils that are certified to meet the 502.00 and/or 503.01 VW oil spec should be used.

    Regarding how oil looks, its relative darkness is completely irrelevant, there are plenty of used oils that are as dark as coal that are still extremely serviceable where there are other used oils that are as amber as honey that are completely exhausted. The only way to know for sure of your oil is holding up is to have it analyzed.

    It looks like a mix of some truth and plenty of misinformation.

    Like shipo wrote the max OCI is 5000 miles. The oil MUST meet VW oil spec 502.00 or, if you are really crazy, newer 503.01.

    No car should require regular desludging.

    PS I have Subaru Legacy GT (the one with turbo engine). Subaru started with 7500 miles OCI but recently changed spec for newer cars claiming that all turbo engines should be maintained per severe service schedule (3750 miles OCI).
  • I too have been a victim of Volkswagen's neglect and VW not standing by their product. My car has been in and out of the dealership since I purchased it NEW. Over and over again, oil is disappearing and not in the car at all. Several times I have had to stop my car immediately and have the car towed to the dealership because I could not drive it due to no oil in the car. The engine light went on and specifically told me to "Do not DRIVE". This is absolutely absurd with a new car. I would not recommend a VW to anyone. They are highly unreliable and unsafe as far as I am concerned. Buyer Beware!! VW will not stand by it's product. I have repeatedly gone to the dealership to have this repaired, but the same problem keeps coming up over and over again. VW will not do anything for you. Please save yourself some problems, do not buy a VW as they continue to be out for themselves.

    Not to denigrate your problem, but if I had a car that had a high rate of oil consumption, I think I'd get into the habit of checking my oil level regularly (like at every fuel fill, as the owner's manual suggests) and topping it off as needed if, for no other reason, than to avoid the hassle of getting a tow. But, hey, maybe that's just me....

    If you ever check back here, did the dealership perform an oil consumption test? What was the consumption rate (how many miles to a quart of oil)?

    Hi everyone, am new here and do have a question.
    Have a 2002 Passat 1.8T bought with 8500 mi on it in Sept 2003, currently have 26,150. Have no idea what oil was used before I bought it and what I used afterwards was whatever Walmart/Auto Care Center had that was called for in the book. I have been reading this forum for awhile now since I had heard about the sludge problem so now I have ordered the Mann filters (larger ones) that are VW specs and have the suggested Mobil 1 0W40 and drain bolt gasket. Now for the question: Is there anything I need to do in particular before I change the oil and put the new "good" stuff in? Am doing it myself.

    Thanks,
    laottoman

    I never did that on any car. But it should be simple as long as you follow the right instruction and have the tools. You can find the instruction on those car manuals. Keep the draining period long to let the old stuff goes out as completely as possible.

    I have a 2000 passat 1.8T and its about that time to change the oil. What kind of oil filter should i get and what tools are needed. I know the Mobil 1 and Castrol syntec oils are good but what about Penzoil.
    thanks
  • shiposhipo Posts: 9,152
    Pennzoil Platinum is a good qualiy Group III wannabe synthetic oil that I believe meets the 502.00 oil spec (the bare bones minimum for your engine), however, I don't believe that it even comes close to meeting VW's more stringent oil specification called 503.01 (a spect that is met by Castrol Syntec 0W-30 and Mobil 1 0W-40). Said another way, no chance I'm using a Group III oil in blown VW or Audi engine.

    Thanks greatcars..I am a little concerned about the sludge problem though, wonder how much of a chance it's had to build up in 26k. I almost only drive it on the weeks ends since my wife doesn't drive and I take it atleast 25 mi one way to work and back, very little around town or stop and go driving. Who knows what happened the first 8.5k, was a lease. But gonna start using the good stuff as I have seen Shipo recommend over and over...:)

    Hi again, thought I'd throw something else in the mix besides my earlier posts #244. Out shopping one day in the Passat, started it up and put in reverse, there was a sort of hard jerk. What the heck but that was all, then I put in drive and noticed hmmmm...kinda slow. It was getting dark so I drove it home as was and noticed that the lights that tell you what gear it was in were "all" lite. Think I drove home in 3rd. Any way got home and stared it again but did nothing unusual. The next several times I drove it the gear lights would light up when started, I'd turn it off, restart it and they'd be off and act as if all was normal. Then the MIL came on and went off so I parked it for a week and it was gone next time I started it and has not come back since then (month ago). I bought one of those diagnostic memo scanner and checked but showed no code. I changed the oil (Mobil 1 0W40) and Mann filter today so I got to drive it and so far nothing. Hope this is end of the story but have a feeling it isn't with all I've been reading about VW's and their problems with the 1.8T. Yep, I got a little long winded. Anyone else have the same problem?
    Danke

    When all of the gear selection lights are lit, you are in fail-safe mode. The tranny does that to prevent self-destruction.

    The tiptronic's transmission control module is under the front passenger's side carpet, in a well. Has your car had any water intrusion issues? Sometimes the TCM goes wack if that occurs. You might want to check your floors for signs of water. Also check under the hood to see if the air plenum (the area where the battery lives) is holding any water from clogged drains under the battery and brake booster.

    Thank you Altair4, I will do that. I had read where there are problems caused by just the thing you suggested. The car is garaged 90 pct of the time but who knows, anything is possible. You know, I did change out the air filter and the cabin filter about the time this started but didn't notice any water in the air plenum.
    Danke Altair...

    Hi, i was just wondering what kind of air filter for the air cleaner and what kind for the cabin I should get? What would the price range be on those?

    Much obliged,
    alen :)
  • alen3alen3 Posts: 12
    my coolant is low and i was wondering how i would go about refilling it. also the hydrolic fluid is on the dry end. Suggestions?

    thanks a bunch
    alen :)
  • laottomanlaottoman Posts: 16
    alen3, I got the air filter at Auto Zone for around $15-17. The cabin filter was at Walmart for about $13. Look in the filter books they have at the store and it should tell you which one you should install. I don't remember the parts numbers now.
