Re: Dark Engine Oil
It is normal for new oil to go black quickly. However if there was some oil oil still present or the inside of the engine is dirtier than normal it will get black even more quickly.
The detergent additives in new oil tend to make all of the dirt in the oilways get suspended in the new oil, which prevents them from blocking up.
I wouldn't worry too much, but I would change the oil at 6,000 mile intervals instead of the recommended 12,000, as I personally think 12,000 miles is too long.
