Default The Best Fuel for Boats?

Hello, guys!

Cars and airplanes use different fuels (with different amount of oil in it.). What percent of oil in the fuel is the best for boats?

And generally, what fuels (15%-20%) are the best ones for sport boating, for example, Traxxas, Blue Thunder, etc.?

Thank you for your attention.

The general concensus seems to be 18-20% oil. On another thread I read of a long time racer experimenting with lower oil percentages; as you reduce oil% you pick up speed and he said that he continued to pick up speed gains until he got as low as 6%! If you ever want to try non-standard ratio's of nitro/methanol/oil and dont want to mix your own, RedMax fuels will make custom blends for $40 per gal.

I dont have an opinion of the "Best" brands.

This is one subject that will get a lot of different opionions. As stated above aim for around 18 to 20% oil and around 20% nitro. You can vary each component to see what your engine likes best. Going down in oil will increase power but will decrease engine life. A friend of mine uses 5% oil in his pylon racing plane. It makes a lot of power but he does have to replace the bearings every meet.
