Gasoline for older engines

i would be more concerned with the lack of lead in the gasoline and the affect on the valve seats. of course no alcohol unless the rubber and plastic is ok with the solvent.

use aviation gas the start better with that and it don't go bad

If it a machine that is used little, the few gallons that is used a year it is a good choice. Its a lot cheaper to buy 10 gallons of AV gas than clean carbs and fight the crap gas if it sets for a couple years.

I agree with the aviation gas. It is 100 octane low lead and has the stabilizer already in it. It will stay fresh for a long time.

Used to use 110LL in my lawn mower (after siphoning it out of Dad's 300). That 4.5hp Briggs would eat standing bamboo.... (some poetic license used in the telling of this tale...)

Sounds like a good option all right, tried to get av gas a couple of years ago and unless I knew some one with an aircraft I had no chance!

should not be hard to get Av gas. some of the airports for the small planes have pay at the pump's just like filling your car up.

Yes, to pay at the pump at 2 of my local airports, anyone with a good credit card can buy, It helps in tired engines.
