I can buy the stuff at the Moultonborough airport for about five and a half bucks a gallon. Too much to put in the boats or cars but not too much for engines that don't get used often and sit a lot. An example is my home generator. It may sit with the fuel tank full for months, but when you need it, you need it.

So what do I know about AvGas? Well it is 100 octane. It has NO ethanol. And it is only distilled at the refinery, never "cracked" from other fules.

I have been told that I should not use it because it "burns hotter" than regular gas. I dont get it.

87 octane has 125,000 Btu/gal.

E-10 gasoline has 121,000Btu/gal.

Avgas has 120,200 Btu/gal.

So how does it burn hotter?

I am willing to pry open my pocket and spend the moola for fuel for my emergency equipment but I don't want to burn out valves, heads, etc. in the process.

SOWADAYA THINK?

Use a qt. in 20-25 gallons it will dun good. To much will burn a hole in the piston! it will act as fuel system cleaner,to much can damage &it will run poor.
