    prices are going up here in md I usually run everything on 89 octane but Im evaluating the benefits of buying a pricier gasoline vs. shortening engine life if I switched to 87 would the engine life span and cost of it be less than expenses on higher grade gas? what are the benefits of higher octane and how would a lower octane affect the engine

    I was told by my dealer not to use higher octane fuel in my mowers or other equipment.

    I have always used 87 octane in my truck, the gas mowers, and my 2 cycle equipment with no problems.
