I kind of wonder why you guys would not be a strong advocate of synthetic. It is much cleaner. Checked my oil after 3,000 (synthetic) still clean as pancake syrup. Check it after 3,000 (regular) dirty as tar.

Isn't the syntetic better for any car?

However, I can certainly see your opinion on don't fix what aint broke. What about the 2000 models, do they get synthetic?
