I've noticed that the engine oil in my Vauxhall Grandland turns black after just a few hundred miles of driving. Is this a cause for concern and should I be changing my oil more frequently?
ReplyThis is completely normal for most modern engines. The oil is doing its job by trapping particles and keeping your engine clean.
However, if you notice a significant increase in the frequency of oil color changes, it may be a sign of engine trouble. Consider getting your engine checked by a certified mechanic.
