I believe they are all group IV..... And I think he's talking about group V.

RP is like $8.5/qt at walmart. As soon as i'm out of free oil changes i'll upgrade from mobil to RP and prolly go 10k with a filter change every 3k.

Amsoil XL series (probably their biggest seller?) is not group IV, it's group III
