HPDI 250 SERIES 2 Oil Question

Yamaha Lube or Amzoil...Which is better?

[briansgi]

Going to get different answers but here is my take. Amsoil will burn cleaner and cause less carbon buildup since it's a full synthetic as compared to Yamalube. In general you should see less plug fouling as well and less smoke too. Amsoil is an outstanding oil in my opinion.
