    Do you guys use regular 87 octane gas for your power equipment or 92 octane and higer?

    ie) lawn mowers, hedge trimmers, backpack blowers, edgers, grass trimmers, etc..

    My dealer saids to use higher octane 92+ because of less carbon bulid up and will give you more power and a cleaner/smoother running engine..

    payup :help:

    Everything I have in the owners manual requires 87. So that is what it gets

    My recommendation is to use whatever the owner's manual tells you to use. Anything more and you are wasting your money. Higher octane fuel does not burn cleaner, or give you more power. Octane is a measure of the fuel's resistance to detonation, meaning that the higher the octane, the harder it is to light the fire. Today's fuels all contain detergents and additives to help keep fuel systems clean. Save your money and get what the product specifies.

    All my Stihl and Echo manuals call for 89. I have never had a problem with using 87.

    The carb went on my echo trimmer... I had used 87 in it for a couple years. Dealer recommended using 89 and above. I now use the 87 in the mowers, 89 on the echo trimmers.

    I have torn down engines that have had both oct fuels ran through them, and the chamber, top of piston, and valves and head all look pretty close to each other . I would agree with others run what manual says, just on the basis that when it comes to warranty work they always look for an excuse
