I've been a big Amsoil believer having used it in everything including my lawn mower, my Waverunner, Goldwing, Dodge Dakota and Chrysler 300M. They just came out with a European Blend 5-40. If interested, you can go to the Amsoil website and become a preferred customer. I think the oil will run about $5 a quart. Also, you can compare the analysis between Amsoil and Mobil 1. If you don't already know, Amsoil was the first to develop synthetic oils back in the early 1970s.
