We really cannot do much about 90/10 gasoline. It's with us to stay. And it runs okay in boats with engines that are designed to use the stuff.

The problem is when the 90/10 gasoline ages. Rubber parts in the fuel system are affected by what I assume are acids that are produced as the fuel deteriorates/ages.

I've had no issues with my F150 running pump gas. There again, we use our boat a couple of times per week, and gas is tuned over promptly. But for the winter, I did take time fillup with 100% gasoline. And I'm running RingFree Plus and Stabil in the tank. That's about all I can do.
