4 stroke gas treatment

[fatback2]

What is the recomended gas treatment for a yamaha 4 stroke ?

[Sequoiha]

depends on if you are going to store it or run it,, I never store mine, i run it year round and I add Yamaha Ring Free to every tank..

i have a f150 and use ring free and star tron all the time.it is cheap enough.
