Re: What kind of oil consumption are u experiencing?
 

Normal driving is proper warm up and an hour or two of spirited driving to me. Living in rural farm country allows me many unsupervised miles.
I have experienced 400-1000 miles per quart on average over a few cars and 26,000 miles in the past 12 months. Anyone that doesn?t add oil is either fibbing a little or needs to hit 7000 rpm a few more times per hour. 90?s definitely use more than later years. I told a perspective buyer, who thought a quart per 1000 was a lot, that these cars were not for him. Nobody likes adding oil, but when you have no idea where it goes, who?s to argue the fun?

Tell him not to buy BMWs either.

Re: What kind of oil consumption are u experiencing?
 

Mine uses about a quart in 4000 miles, and I wring it out when I drive it. When I first got it used about a quart in 1500, but after chasing down leaks it is where it is now oil pan was the biggest leaker. My E39 M5 BMW used about a quart in 2500 miles, once the leaks were sorted, about a quart every 1000 before that.

I put it in a jar when I am not using it!

LOL, Not sure why you would recollect used oil?

Hi,
How do you explain that oil consumption is higher when filling up to "full" on the dipstick and then less after consuming 1/2 quart?

Oil pan leaks :thumbsup:

Re: What kind of oil consumption are u experiencing?
 

That's fairly normal. Mine drops a whole quart and then stays there. And it's not going through the PCV system. I have a catch can and get very little in there. Haibeck has a write up on this and feels it's an oil control issue through the rings. If you read up on the development of the engine you'll find the engineers had issues with high crankcase pressures. The final solution, that box under the plenum, was a compromise at best. I suspect that once the oil level drops a certain amount its just enough to mitigate the pressures and oil being pushed past the rings, with slight variations from engine to engine. I'd luv to here one original engineers chime in on this tho...

I might guess that a cup of oil is replenishing the 11.6 quart cooling system, and it may have drained out some during the oil change.

How long does it take to consume that quarter?

I think you're right, because I don't know where this oil can go other than PCV (but you told me that the consumption at this level was not more important), or as Dynomite said by a oil pan leak...
