Yes if it's a 2 stroke motor, but for what it costs, you're better off running a premium pump gas with a high quality 2 cycle mix. This stuff cost around 5 or 6 bucks a quart and is really meant for weed eaters and chainsaws etc. I do drain the tank on dirt bikes and put a quart of this in at the end of the season and run it thru the carb. It stays fresh all winter and won't rot your fuel lines and won't gum up your carb over the winter like pump gas will. It's a great winter storage fuel. It will make your bike run great but for most it's too expensive to ride all the time on.
Each batch of fuel differs in octane. The minimum 92 is the lowest the batch has in it, and the 93 is the maximum amount the batch has in it. No different then the gas for your car. The octane cannot be precisely measured in each load of gasoline but the octane is within the advertised amount
"Premix" means this has already been formulated with OIL. i.e. this is for 2-cycle engines that require a typical 30 SAE Oil mix to the gas. In this case, there is a 40:1 (gas to oil) mixture with this product which is satisfactory for most 2-cycle engines.
My trimmer,leaf blower and chainsaw all use 40:1,if I need another trimmer,leaf blower or chainsaw,I will buy 1 that uses 40:1 so I don't have to have 2 gas cans with different mixtures.
No this is for 2 cycle oil mixed with gas engines. They make a version for 4 cycle small engines,
