what tainted and TransAMLS1 said, thats what i was talking about above.

 

Low tension piston rings. Increase fuel economy but also increase oil consumption. Some engines that burn less probably have a closer piston to cylinder wall clearance from the factory.

 

agreed. obviously a car with closer piston to wall clearence will burn more oil. not every motor is the same even if it comes from the same factory. and not all M6 guys run higher rpm. heck my 5 speed rarely sees 2300 unless im havin fun

 

No oil burning so far. The oil level was at the top of cross hatched area before the last change.I have put about 600mi on the recently changed oil and(just looked) is still at the the top of the crosshatched area. I'll be keeping an eye on it though for GP and curiousity.
But after reading some of these posts and visiting the site DomesticViolence provided.I cant help but wounder if the piston slap is a direct influence on the consumption.
I dont have piston slap,havent burnt oil hmm.I must say I have seen some threads on the piston slap and it normalcy.But after hearing that sound bite of what it sounds like gezz the ones who have this"How can you stand it?"I question normal. and the pics of the cylin. walls
I wonder if the votes for Yes it burns oil are experiencing piston slap.If the ones who answered Yes maybe share if you DO or NOT have piston slap w/oil comsumption.

 

I have both the piston slap and oil consumption. The oil consumption issue was a bit more important to me, but it isnt something I worry about. If the light comes on (usually around 2800-3100 miles) I just get the oil changed. If it gets drastically worse, I will of course take action. As for the piston slap, like I said earlier...doesnt bother me at all, every GM car Ive owned has had some kind of of slap or knock, such as my 90 Cadillac Coupe De Ville w/ rod knock. When the cars were brand new, owners went histarical and demanded that GM replace their engines. I drove mine til 212,000 miles without a single problem. And heck, GM isnt the only one, Ford owners are having 'issues' with piston slap/knock AND oil consumption with their bread and butter 4.6 V-8 (especially with the F-150 Lightning) However, some situations are a little different.. I agree that certain owners have a legit argument... if the piston slap is gradually worsening and/or is unusually loud and/or does not go away when the engine warms up.

Yes, it burns oil - about a 1/4 to a 1/2 quart every 2200 - 2500 miles.

I have a 2800 stall, so my car is probably more akin to a M6 than perhaps other A4's.


Never had the piston slap issue (that I know of ) - but, I thought that applied to the newer ( ' 01 & ' 02 ) engines.

hmmm.. this is all so odd.. mine doesnt burn anything..

I just ran about 7500 miles from oil change to oil change too.. with many dyno runs and a few trips to the track in there...

nothing out of the ordinary there
