Engine Oil

[Kracka]

Here is a little more synthetic oil info for you people:

Castrol's new Syntec has superior protection properties over Mobil 1, but does not last as long. If you change your oil every 5k miles or sooner, you'll see no benefit to using Mobil 1, but if you stretch it to 10k or so I would use the Mobil 1. Not a bad idea to change the filter at 5k if you plan on running 10k or more between oil changes. Synthetic oil actually protects your engine better once it is slighty used (~3k miles)...in other words, more engine wear occurs when the oil is fresh out of the bottle. Color is no indicator to the oil's condition so just becuase it is black or a very dark brown does not mean it is worn out.
