For those taking their cars to service, it'd be nice to switch to the new oil cap... if it's any better indeed. I do my own oil changes, but if you don't coat the gasket with a light film of oil (like on regular oil filters), the gasket can bunch up and make a royal mess, like many owners have found out the hard way. Cap looks identical on the outside other than the lack of an oil bottle symbol. A pic from the bottom (any '11 owners reading?
) would be nice to tell the difference, if any.
