If I wanted too, could I run 110 racing gas in my 2013 Spotsman 500HO
If you like wasting $$$. High octane fuel (racing fuel) is for high compression engines. The 500 is NOT a high compression engine. A good premium unleaded around 91 should be plenty. That's what I run. It's non-ethanol here, where the lower grades all have ethanol added.
When I had to have my engine rebuilt for the second time, the warranty company as well as the dealer, advised me to either run non-ethanol gasoline in my machine or if it is not available to use the Stabil Marine ethanol treatment in my machine. Dealer advised it to be used in all small engines as that is what he works on and sees all kinds of problems with the ethanol now. In his 2 stroke sleds they all run 110 octane as it is ethanol free. He told me that ethanol will attract moisture and they went to a seminar on the affects of ethanol and it was stated to them that in studies ethanol was attributed to piston rings getting gummed up and causing them to stick and burn oil. After they showed me the pistons that came out of my machine the second time around I am inclined to believe them. I agree with the above posters that while 110 will not harm your engine the higher octane will burn cooler. In a high compression engine this is what you need because as mentioned before it will not pre-detinate like 87 octane will. I have tried 87,91,93 all in my 800 and the mpg and performance differences were very negligable. My 800 is a pig no matter what fuel I run in it.:motz: I am not even sure what high octane goes for now but I remember paying like $6 a gallon for 114 aviation fuel back in 2005-2006.[/QUOTE 110 Octane was going for about $7 a gallon about 4 yr ago. Not sure what it is now.
