A sidenote for all you synthetic users: WARNING, Beware of so called "synthetic" oils. Many petrolatums distribute oil labeled as synthetic when in fact it is natural oil which is only modified or blended. Mobil is one of the few who actually produces a 100% fully synthetic motor oil as labeled on the bottle. Why else would Porsche fill every car since new from 94 and up? As if I had to tell you guys Mobil 1 is the best oil on earth! I have seen first hand the internals of high mileage engines which use this stuff. They are as clean as the day they were built with no sludgy build up that you get with natural oils, regardless of ritualistic oil changes. It can also be used to clean any older engine with this nasty buildup. And it can be mixed with, or used in place of your current oil. Of course, always use thiker oil on older engines, especially leaky ones.
