    I only fert lawns, but my home 21" Toro mower (6yrs old) had some severe running problems. Mechanic said it needed carb work, $50. Works great now. He said I should consider using premium gas vs. regular gas. Anyone else agree with this? Why?

    i wouldn't waste the money, especially with gas prices this high.. In a ZTR yes, maybe, but in a $300 mower no way

    I never heard that one. Every mower I've ever used, the manual said to use regular octane.

    Nope, I've been through a two semester course on small engine repair and both instructors said run FRESH unleded regular in the motors. The preimum stuff has addatives that are abrasive and will wear out the rings.

    That being said, I always run whatever grade gasoline the owner's manual recommends in any machine I own.

    Don't waste your money, it doesn't need it.

    I have heard that premium is better for small engines. I use mid grade in all my equipment.

    I was originally told and have since always used premium unleaded petrol, mainly in the Toro Z.

    Even in the Honda line trimmer the premium unleaded gives a bit more power than straight unleaded crap.

    I seriously doubt this. I have three mowers with over ten years commercial use so I think this blows that theory, in my opinion anyway.

    Norm Al is on the money. If it doesn't ping, no need for higher octane.
