I don't think we can go wrong with any of the oils we use honestly.I'm running a Rotax 503 on a Challenger II light sport. If you ask 10 different "Experts" you get 10 different answers. The one particular expert that did my overhaul, when I hit the magic number of hours recommended by Rotax, recommends AMSOIL Interceptor or Havoline. Another guy has had great success running AMSOIL Saber. A local friend running the same set as I am has had no issues running penzoil outboard oil.
Where you flying that thing out of?
Do you go to any of the local fly-ins?
Ours is doing fine with RP, and would as well with AMSOIL, I'm sure.
Omni airfield in port allen.
haven't been to any fly-ins in a long time.
