Hi
Had a NZ new E38 740 for over a year with no issues, and no oil leaks. Went to a mates place and parked for about 5 hours nose down on his very steep driveway (new house with a new concrete drive way - one of those pebble effect ones) and when we left there was an obvious pool of oil on the ground.
Turned on the engine, got no warning lights, turned on OK, backed up OK and checked oil on the level - OK. Drove home and next morning there were just a couple of oil spots on the drive way. I couldn't see any obvious place where the oil had come from, although there was oil on TOP of what I assume is some form of oil/sump tank. Got some foaming degreaser and cleaned the mess up. And now 2 days later ther isn't a sign of any further oil leaks.
Any ideas on what this could be - there shouldn't be any oil overflow should there?
Any any advice on a good product to clean up a mates driveway!
Thanks
