Default Running different fuels through engine

Hello, Would it hurt my saito 91 to run different types of fuel through it? All that I run through it will work with it.

Thanks

I was using the cool power 15% nitro 4 cycle fuel, what the manual said. The manual also said I could use a high powered 2 cycle fuel with 15% nitro. I have the 2 stroke fuel with 15% nitro. Ive been running the cool power 4 cycle. Will the 2 stroke stuff work?

Thanks

as long as the the 2 stroke fuel has 18% oil content I don't see a porblem, I could be wrong. I dont own any 2 strokes so I only have 20/20 4 stroke fuel

Two stroke fuel if it is the same percentage of nitro methane as your four stroke fuel is not "high Powered fuel"

The only real difference between two or foustroke is primarily the quantity of oil thats blended in it. Many folks including myself will not use fourstroke fuel in their fourstrokes. I have never used it in any of my fourstrokes preferring to use fuel with more oil.

So the answer to your question is: yes the two stroke stuff will work just fine.

Short answer: No, as long as each fuel meets Saito's requirements for oil content. Depending on how different each fuel is you may or may not need to adjust the carburetor every time you change.
