0w40 oil?

Less viscosity = more HP (so it’s claimed and I’ve read/heard). You’re going to pay a bit more for synthetic 0w* usually, though. Look up Royal Purple, Amsoil, etc. for details about their claims. I’d like to be standing next to the dyno and read charts of before with regular 5w30 dinojuice versus after a flush & 0w* synthetic.

now your gonna get every ricer running out to find 0w for that extra hp, lol
