Did a search, but didn't see these answers. Original owner of a 2002.

Up to 26,000 miles. Just started driving it regularly, so never took notice of how often I added oil. Notice a quart low at 1500 miles, then stayed there to 2000 miles and I added oil. A few questions. Last time I read about this here it did not include 2002. Then again, the seat track was not supposed to be in 2002 either and I had that problem too.

Does the problem now include 2002?

Once you are a quart down, could it stay that way for another thousand miles or will you use another quart the next 1500-2000 miles?

Seems that a quart for 2000 miles is considered acceptable? Really stinks as I sold my winter car with 185,000 miles on it and it didn't use any oil despite a little bit of dripping.

Will it get substantially worse as the miles climb? At 50,000 will I be using twice that amount?

I'm an A4 mostly highway at 75mph. No high revving at light loads, so ring flutter should not be an issue.

If it is not expected to get worse, the conclusion is live with it because it is GM borderline, right?

 

I remember seeing posts in the last year where some of the guys have used Castrol 5-30 oil made in Germany and they said it helped, you might go back in the archives over the passed year and look for some of that early info regading oil consumption. It will only cost you an oil change to find out.

 

For the most the oil consumption affected early production 2001 models and mainly MN6s. Many people including myself saw +1.25 quarts within 800 miles of driving. It would even be worse if it was hard driving.

Many here (and GM) will say that1 quart every 2K miles is really not that bad, but of course it is a matter of opinion. Like oyu said you had a car with 185K miles and it never burned any oil.

You could have the car go through a consumption test if you are still under warranty. They will test it 3 - 4 times and see how much oil you are burning. If you are burning 1 quart every 2K miles GM will not help you.

If you don't have warranty anymore then don't even think about getting it fixed. The cost is some where in the $3K range and that is alot of quarts of oil.

I know the cars that were affected by the oil consumption did get worse when as more miles were put on. I would say that chances are your car will not use more oil, but probably about the same since it is an A4.

I know it is a sucky decision, but to be honest if I was burning 1 quart everone 2K miles I would have not had the rering done. It is major work so if you do decide on having it done make sure you find a good vette tech...

 

Bought my 2k A4 with approx 20,000 miles on it. Noticed that it used approx 1 qt every 2000 to 3000 miles over the first 10,000 or so. Asked a c5 cert mechanic about it (not my dealer) and he recommended that I add some techron to the next 3 tanks of gas and then check for improvements.

I did that and then got the oil changed. It burned 1/2 quart in the next 4500 miles. Much improved. Still not perfect, but much better than before. Now I just make sure to add techron every other tank or so.

Above and beyond the techron, he also recommended the GM Top End cleaner treatment or switching to the Z06 PCV system if the techron alone didn't clear things up. You can search the forum for details about the top end treatment or the Z06 PCV conversion. Some people also have luck with "oil catch cans".

02's are supposed to have the new pistons, rings, and valley covers, but I have seen posts where people with 02's still had oil consumption issues. According to GM, gen 3 small blocks using 1 quart every 2000 miles is "normal".

 

I'm the original owner of a 2001 MN6 with 19K miles. I'm now burning 1qt per 1k miles with non aggressive driving. Dealer is monitoring the usage but I'm really goosey about having them tear the engine down and do a re-ring. My dilema is will it get much worse or should I just live with this oil usage? Advice appreciated....

 

it is a hard decision. The work is not really that bad, but they do have to pull the engine apart to get to the ring they replace. I was burning +1 quarts and up to 1.5 quarts every 800 miles under hard driving. That was way too much for me and I happen to have a really good vette tech so my decision was made easier by that.

 

Did you have any problems as result of the teardown? Also, one of the tech's siad I'd likely re-experience oil consumption after some time even with the re-ring. Not exactly a stong endoresment to have this done and risk other nuisance issues as result.

How did you make out?

 

I am not sure if I will burn more oil again or not, but I can say right now I am using less except on race days when I seem to still use a ton (which I guess is expected).

I did not have any issues with the teardown. The guy that worked on mine has done many of these and is also rated as on of the top vette techs around (Tom from Defelice Chevy in Pt. Pleasant).

It probably comes down to how much of a hassle is it for you to watch your oil levels. For me using 1.5 quarts for 800 miles was just too much to watch all the time. If it was 1 quart every 2000 miles I would care less since I usually change my oil more often due to racing, but 1.5 quarts meant I travelled everywhere with oil in my car (though I find myself doing that now anyway).

 

Thanks for the honest answer. I'm using exatly 1qt/1K miles with basically modest driving. I do downshift allot when I takes turns or get off highways, part of the fun of a corvette and 6sp. I do NO racing and hammer it very infrequently, only when the wife isn't with me. I'm still in a quandary about doing this repair. I'll probably wait a bit more to see if this gets worse. Trouble is winter is coming and I don't use the car so i'll have little chance of seeing the trend. My dealer is Hawthorne Chevy, great folks, the tech said he's done many of these and he's not pushing me in that direction at all, nor is the servce mgr, also a wonderful guy. We'll see where we end up in time.

 

I agree, To me the problem is mobil 1,
93 lt-1 consumes mobil
94 z28
94 silverado
98SS
02 zo-6 All would drink MOBIL 1
ALL WOULD NOT USE OIL with Castrol syntec
Mobil 1 burn rate is horrible, Like Gm must get it for free
for the recommendation on the oil cap.
Mobil 1 stinks,worst syn on the market
Case in point, 16,xxx on the z-06 2600 mlies full to the top
Mobil 1 was down 3/4 qt @ 1400 miles
