Hey guys! My one year old Z currently has 10,000 miles and on my last oil change I switched to full synthetic. With synthetic I generally wait 4000 miles before an oil change but today i decided to check my oil at 3400 miles. After checking the oil I noticed that it appears to be discolored but not completely black. I would say its halfway between the original color and full black (like my 200,000 mile mazda truck oil is). I still consider my car NEW but is this consistent on all engines after breakin. 99% of the time my car is driven like a baby! Is this normal and if not any advice. Thanks, Buzz

 

its normal dont worry about it
