Gentlemen,
So y'all are saying it should run 1/2 quart below what the manual says is the FULL level? Where would that read on the dipstick?
When the engine is cold, I note that my oil level tends to be about midway between the min and max lines. If I check it hot a few minutes after shutdown, I note that the level is signifciantly higher, right up at the maximum mark. From your experience, where is yours at when it is 1/2 quart low?
My carport doesn't have any telltale oil stains.
As for the A/C on this car, if/when it goes out, I doubt I'll pay to get that redone. I'm sure it is pricey. We only have a couple of months of real summer weather here in the foothills to the mountains. And I don't consider it that hot, but I grew up in Texas, where summer is much more brutal than around here.
Autobahn Service Center in Bristol is an indie garage that works on Porsche, BMW, Volvo, and Mecedes. They work on alot of old BMW and Porsche cars around here. I've got my eye on a 1985 Porsche 944 that is just sitting in my neighbor's garage collecting dust for over a year due to a bad clutch. Whenever he gives up on it and gets ready to sell that one, I'm gonna take that one there to have it checked out, and make a lowball offer. Seems a shame for such a nice car like that not to be driven!
Mercedes revised the fill quantity for my diesel engine as well through a TSB.
