Question about alcohol based gas

Sorry, I posted this earlier to Buy/Sell by mistake,

I have been told not to use alcohol based unleaded gas in my old lawn-mowers, weed wackers, etc, because it causes damage to o-rings and gaskets.

Does the same warning pertain to older mopeds.

I have a 1980 Sachs Commuter moped with 49cc 2 cycle engine. It runs perfect and thought maybe cleansing ability of alcohol base would keep it running that way

I think its the acetone, not the ethanol. I know its bad for plastic, but I don't know about rubber.

Re: Question about alcohol based gas

I should mention I am talking about gasohol, if it has acetone in it I won't use it.

I missed the part where _leefran_ said he was using Acetone.

Could you point me to it??

Thanks.

He was talking about what I assume would be the newer premium types of gas, they contain acetone.

Re: Question about alcohol based gas

I know that some people advocate adding acetone to gasoline to increase its volatility, thereby improving gas mileage. I was unaware that any oil companies were selling gas with acetone as an additive.
