i really admire you doing this work.
So, i have this 2004 BMW 545i it has 66000 miles drives awesome, but the Low Engine Oil light comes on every 300 miles. I fill the engine oil every time and it repeats the same.
I dont see any oil leaks on my driveway or parking spots. To rule out the possibility of oil leaking and getting stored in the belly pan, i tried parking it inclined but still no leaks.
No smoke coming from the exhaust but just when i start the car in the morning after a whole night rest.
What could cause this? Any help will be appreciated.
