...says my board computer sometimes. IŽll have a shop look at it. I suspect a small leak somewhere. But was wondering if somnebody might have experienced this before (91 750iL).
No chocolate-oil symptoms...No darking of coolant. So the oil just seems to leak out into nothing. I havenŽt seen a drop of oil on my garage floor either. Mysterious little thingy. But hereŽs the background.
Bought the car right after Inspection II where a BMW dealer had changed all oils and filters. Oil was clear and nice. About halfways up the stick between min/max. Milage: 187000 km (divide by 1.6 for miles).
After a medium hard drive at higher speeds (100-120mph) for an hour I stoped to refuel. Then the Engine Oil Low warning came on. Waited 10 minutes to let the oil settle and checked. Just on minimum mark. Refilled about a liter of oil... This was at about 187500 km.
Took it a bit easier just in case and the warning didnŽt show until about 189000 km after I had done several kickdowns and fast drive bys. Hey, a V12 can be fun ;) Same thing. Refilled about a liter.
Now today it again showed after I did a series of accelerations. This is at about 191000km...
It seems that if I rev the engine for a longer period or drive "hard" it looses oil. Or it could just be a coincident, and that it looses oil at a slow rate.
Any ideas what it is? Like I said, IŽll have a shop look at it soon to correct it anyways.
