i used to like castrol 20w50.


but once i made the switch to synthetic, i realized i was missing out the whole time.

synthetic oils don't burn off as badly, they don't gunk up and stain and discolor the engine internals, they are way better when dealing with heat / cold / and all sorts of other great things.

a good website to check out is www.bobistheoilguy.com that is, if you're crazy .
