    2004 msx 110

    I read on hear the 150 msx requires premium fuel, is this the same for the 110 msx or is regular okay?

    We only have regular at our lake, will this be a problem?

    Arrow Octane requirements for Weber turbo-charged MSX 110 and MSX 150 engines

    What octane grade is the regular?

    Does it have Ethanol in the gasoline?

    Can you buy your fuel at a road-side gas station, instead of at the water's edge?

    Remember, you have a turbo-charged 750cc two cylinder four-stroke engine, producing 110 horsepower. Fuel requirement from Polaris is 91 octane.

    That engine is fairly fuel efficient, but it needs the octane to be kept happy.

    You can look at the MSX 110/150 Service Manual. Includes the fuel octane specs.

    I'd invest in a handful of 5 gallon gas jugs...got to be cheaper than an engine rebuild!

    The knock sensor will retard the spark to reduce detonation, if the octane is too low...but that is not a guarantee that you will not do some damage.

    And like Rocky said the knock sensor will pull timing out of the motor. Loss of performance and speed most times the RPM's will run at 6800-6900. Premuim makes that motor happy.

    Should non ethanol gas be used? Or regular pump premium 91?

    Definitely premium... 91oct or better. Turbo engines need the added detonation resistance of premium.

    Most gas these days, even Premium, have 10% (max) ethanol in them. If you have Premium without ethanol, even better. But either will work fine in the MSX 110/150.
