fuel grade

[Lawngeek]

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

[jrebeiro]

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

[Lawngeek]

just in the small engines and 2 cycle mix? why is that, what about for trucks

[Eric ELM]

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