on my caprice when i start the car my oil gauge is at the middle but when i start driving around and my engine heats up it drops down in to the low red zone...or just above it actually..... i know i have an oil leak but it is really small and i still have alot of oil in it because i check the stick every week..... and its been doing it for awhile but i havnt had any oil problems... if u guys could let me know it would be greatly appreciated
