When I pulled my injector housings for porting, the secondary intake valve stem was totally crusted up. I doubt it had to do with gasoline choice so much as oil through the intake, leaky injectors, and a lack of using the secondary system often enough.

I think premium octane and frequent exercise is the best way to keep the engine running clean.
