Does the problem occur only at low RPM? If so, the solution is either lighter throttle, a downshift or higher octane gas (assuming you are not already using the highest available in your area).
If it can occur even if you're at... say 3800 RPM, then higher octane becomes the only answer.

Non-firing cylinders also wash the oil from the cylinder walls with fuel. Some of that fuel also makes its way past the rings and into the oil. You should definitely pop the dipstick and sniff the oil. If you smell gasoline, change it immediately. Even if you don't you might want to change it just on principle. Cheap insurance.

But in normal circumstances it seems like overkill for an engine with modest compression and a relatively low redline.
Synthetics, to me, make more sense in very high revving (think S2000) or turbocharged vehicles (WRX).
With that said, I swapped my Miata's transmission and differential oils to Mobil 1 synthetic. Gear oil is much thicker (75w90), but I can feel a slight improvement. When cold, gears engage noticeably easier, and when hot there is a small improvement too.
Why? Gear oil is a whopping $9 per quart, but you only use 3 quarts that last for years. Oil changes are more often, so synthetics will cost you $20 several times per year.
I wanted to try synthetic, but somewhere where I can feel the difference directly. Also, it won't bleed my pockets dry.

Thinking of changing the gear oil to Redline 75W90NS because cold shifts are a bear. It's only Fall but we have had a lot of January-like days.
Dennis
Mobil 1 gear oil has been fine, FWIW.
5w30 is pretty thin oil, but I'm surprised you got a leak like that.

Good info; I'll check the oil. I could probably convince the dealer to take responsibility [personal responsibility.. great concept] (though it would take less time/aggravation to change and recycle the oil myself than make two round trips to the dealer). Thanks WDB <161</A>> (and Colin <157</A>>).

Castrol Synthetic motor oil is more viscous than petroleum-based; for that reason alone I would not use it, but that is why it will leak less. Valvoline fully synthetic is less viscous than petroleum-based and gives easy starts as 10W-30 down to 0° F instead of 10°F for petroleum-based. Since it can be left in the engine longer than ordinary oil, the added cost is not so great. Once in a while I do expect my SVX to do 7000 rpm, so it qualifies for synthetic on that account.
The way I look at it, with potentially increased mileage, longer change intervals (I feel that I can go 7500mi safely with Synthetics and a good fiber filter), the cost difference is nil, plus, I only have to change oil twice a year.
Thanks for the responses,

oxygenated gasoline decreases emissions.
Of course they don't reduce the stuff actually coming out of the tailpipe. They reduce carbon MONoxide by making more oxygen available in the hopes of producing carbon dioxide. The former being more dangerous for a variety of reasons...
That is the whole trick, nothing more. It works too... but oxygenated gas doesn't burn as well, from a power standpoint. It is fairly common to see gas mileage drop and notice a difference in performance when using oxygenated gas.

This time, they did not include the code on the service printout. Instead, it says:
CAUSE: INTERNAL FAILURE
A455151 REPLACE OXYGEN SENSOR
478 WS 1.00
1 22641AA011 SENSOR AY
A/F RATIO
FC: UFP-42 PART#: COUNT:
CLAIM TYPE: WS
AUTH CODE:
REPLACED AIR FUEL SENSOR
(why they insist on uppercase-only, I may never know :-) ).
The "WS" stuff is obviously "warranty service" and the second big number is clearly the part number for the "SENSOR A[ssembl]Y". I wonder what the actual code was, though...
I normally do my own oil changes, but the last one was at 11000 miles, and the last time I went to Pep Boys they were out of the 5W30 I normally buy there, so I had them do that too. Total cost $31.12 -- the diagnostic and sensor were covered under warranty.
Interestingly, there was no wait for new sensors. I guess the backlog, from the bad batches that were out last year, has been filled.
15k mile service is coming up -- is there anything I should do other than replace the air filter? (I skipped Diablo's 15k-service; they like to fiddle with all kinds of stuff, and charge an extra hundred or two.)

The tiny lights on the heating/cooling fan switch, the fan speed 0-4 indicator and the temperature control lever no longer work.
Does anyone have any suggestions on what to do?
The mileage is 63,000km / 39,000m

Could anyone give me any information on getting a heat shield off of a '93 Subaru Impreza wagon?
Thanks!!!
The problem is the offset of wheels subaru chooses to use. They have a lot of backspacing (positive offset), which allows a lot of snow to build up in the wheel which will affect balance. The same thing can happen in mud.
There really isn't a solution other than cleaning the wheels out once it happens. I have noticed that my 15x6 steel wheels haven't had the problem yet, whereas my original equipment 16x7 alloys had it several times last winter. Of course I also have snow tires on the steels, so perhaps I'm not getting stuck down in the snow as much...

The Heater control slide light was equally difficult, requiring to take apart the dash panel, removing the heater control unit (disconnecting the ill concieved heater cable - held on with a 'C' clip). Then taking the control unit apart to finally get to the tiny bulb. This time, I couldn't get a replacement bulb, extra long 'prongs' required. But as it turned out, the bulb just had a loose connection and came back on after testing and reassembly.
Bottom line, doable, but only if you are not afraid to take things apart, some risk in snapping off important plastic 'click clips' and taking your time.
Personnaly, I dread the next brown out that invariably will come!

Regular expoy glue and super glue did not hold sufficiently.
What I did find that worked best was a combination of a special super glue for plastic (two parts, one 'preparer' that appears to be acetone like and comes in a nail polish type vial. Second part appears similar to regular super glue. That held well, but I didn't think it would have the strength to endure!
What I discovered and used was plastic epoxy. It is a sort of clay like product that you first knead with your hands to mix the center and exterior parts together. Then I squished that stuff around the base of the glued parts to give a lot more support and strength. Hardens up after 2-3 hours. Worked GREAT!
I was sweating bullets not wanting to buy new trim pieces!

Are you sure the sound is knocking due to fuel pre-ignition? Your Forester engine has been designed for 87 octane fuel. In some cases, you might hear some pinging under load, but knocking is probably extremely rare. Can you describe the noise a little more?
Ken
problem : when I come to a stop and then accelerate
again ( even very gradually ) I occasionally feel
a jolt within several seconds. It feels like
something was held and then is released , or like
something suddenly engages. The car was driven very
rarely in the past 6 month ( I was out of town
most of the time ). The problem appeared a couple
of weeks after I resumed regular driving. Does this
sound like normal behavior for this
particular vehicle ? I understand that when front wheels slip rear ones get more power. Is it a gradual increase or could is happen with a thump that I can feel ? How bad does traction need to be on the front wheels for the transfer to take place ? I am mostly experiencing the problem on slippery roads, but first time it happened under normal driving conditions.
Have the dealer take a look at it so it gets documented.
It almost sounds like a quiet diesel when it is idling. Not sure about wether it's pre-ignition or what but it sure does knock some.
Any ideas??
Jason
Is the noise there at all times? I was thinking it could be bad spark plugs or even piston slap, but it's hard to say without actually seeing it. I would take it into the dealer since your 98 is probably still covered by the powertrain warranty. Same for the noise you described while steering.

I found out today that the windshield, because it is heated (windshield wiper de-icer is standard in the S), cannot be repaired under any circumstances - it needs to be replaced. I was told that the windshield retails for $1,600!!! If I pay cash, rather than going through insurance, they would charge me $800. If I go through insurance, I have to pay a $500 deductible. (This is questionable, too - my insurance company is giving me trouble about even being covered in my new car, since my policy paperwork was not officially switched to my new car until a couple days later! This was NOT my fault - I called them right after buying the car, but they were slow in processing the paperwork. I did ask several times about whether or not I was covered during this interim, and they said YES.)
This is a warning to anyone who has this car: lower your windshield deductible if you can. I didn't know I had that option. Now I'm stuck paying lots just because of a little rock. So much for the honeymoon period of having a new car...
Do I have any other options? Is it only Maryland that won't repair a heated windshield? Could a warranty possibly cover this, since it happened the day after buying it? Any chance the dealer would help me out? (Fitzgerald's)
This is really terrible.

As for the windshield, they too will repair a cracked windshield, if possible. Probably for more of those tiny hole type cracks, and not the cracks that go across the glass. If the glass can be repaired, they do it for no cost to you (no deductible). If it can't be repaired, you'd then have to use your deductible to get a new one.
I had my windshield replaced last winter on my previous ride (Chevy Z71). It was cracked along the bottom half - so no repair! I paid my $50 deductible and had KD AutoGlass put in a new one. At least in my area, State Farm uses KD AutoGlass and Auto Glass Specialists (the guys in the little red trucks).
Our Outback has the same heated windshield. I would suspect that a repair of that windshield wouldn't be advised since the heating elements put a bit more strain on the glass itself. So, that repaired portion of the window would be put under even more strain.
But, alas, I'm no engineer! I'm probably wrong. And hey, my post made it!

I don't see why you couldn't repair the Subaru windshields unless the chip/crack was right over the heating element (down near the wipers). If the damage is elsewhere, seems to me that the heater would be irrelevant. Even then it might be doable -- simple warm-air defrosters (which we all have) already put thermal expansion stresses on a cold windshield, and I can't see how the wiper heating elements would be any worse (they don't get hot-hot, just warm enough to prevent ice from forming). I can see not going the repair route if it's a more serious crack, but small chips/cracks?
I might be tempted to buy a repair kit and fix it on my own if possible.

Pull the wheel well cover up and on the passenger side remove the carpet section and soundproofing (you may need to remove the wheel well soundproofing/underfloor to do this easily). Now feel along up underneath the side panel and the harness plug should be there somewhere in the middle. You do need to reach up a little bit (small fingers help!). It's not too obvious.
If you want, you can lead the wiring down through a plug in the bottom of the wheel well (need to remove the tire to see it). However, in my installation (a HiddenHitch), anywhere I can see to tie the harness up is pretty far forward and hard to get to for occasional use, so I'll probably keep my wiring in the wheel well and lead it under the tailgate when needed.
(sorry I don't have a nifty digital camera to show you a picture of this...Santa, are you listening?)
Hope this helps someone else.

When you bought your new tires four months ago, did you get 2 or 4 new tires? I'm trying to understand how the tire tread differed by 1/4 inch. I'm assuming you bought the same tire size so I'm going to guess that you replaced just two at that time.
The dealer is right about needing your tire tread being within 1/8 of an inch. More accurately, it's your entire tire diameter needs to be within 1/8 of an inch. The reason is that our AWD systems detect rotational differences and engage accordingly. When your tires are slipping, chances are one is going to be spinning faster than another. The AWD system can't tell apart from slippery road conditions and having tires of different diameters. It all just looks like different rotational speeds.
With AWD vehicles, you pretty much have to replace all 4 tires at a time.
Having said that, the AWD systems in our Foresters should be relatively transparent. That is, you shouldn't feel any jerkyness under normal driving conditions even if AWD engages. After you get the other two tires replaced, pay close attention and see if the symptoms remain.
Good luck,
Ken
