I was keeping the oil in the water bottle about 6-7 months and did sent recently to BlackStone and they came back today.
I purchased the car at 29.9K and I drove 6K and replaced the Oil. Oil changed by Classic BMW Dealer in Texas before shipped. And I got fuel pressure rail sensor problem after 50 miles drive at the very first time. Went to dealer and fixed the problem.
So I was driving the car about 4K after I changed the oil at 36K miles and the odometer is currently 39.9K right now!
Engine sounds and runs very good and always drive hard after warming the engine up.
So should I send another sample at that millage? Just getting out some oil from the pan?
Note : This is a Sunday Drive car and there is times I do not drive about 2 weeks. So the cold starts are real COLD!
