JLWelding Posted May 29, 2014 Report Share Posted May 29, 2014 Back in the day we used to go to the airport on a empty tank and fuel up with ten gal. and go to the quarter mile. Can you still run air craft fuel ? The reason I ask is we have a eng. that's not real high in compression and expense wise 10.00 gal for race fuel and 5.00 gal airplane fuel I thought why not run airplane fuel.Thanks for your thoughts Link to comment Share on other sites More sharing options...
mfbarnes Posted May 29, 2014 Report Share Posted May 29, 2014 Use to run JP4 back in the day. That would be a question for the sanctioning body, but I'm guessing if they allow race fuel AvGas will be fine. However AvGas isn't what it use to be.

txtom Posted June 3, 2014 Report Share Posted June 3, 2014 Keep in mind that if you were to rate the octane of avgas to the same scale as automotive gas, 100ll rates out to the equivalent of 96 octane pump gas. a little history for ya, anyone in the 60's to the 80's that used racing gas were probably using avgas without knowing it. Several racing fuel manufacturers bought avgas in bulk and mixed in their own additive packages, mostly TEL to increase the octane. Not all the manufacturers did it; I believe Sunoco and Union 76 cracked their own fuel, but most of the smaller companies bought and mixed avgas.

JOHNFOSTERJDHUGHSFAN Posted June 4, 2014 Report Share Posted June 4, 2014 I think you would be better off mixing Pump gas 50 / 50 with Race gas or mixing it 60 % pump & 40% Race gas ect !!! Link to comment Share on other sites More sharing options...
Mayhem Posted June 15, 2014 Report Share Posted June 15, 2014 I run 50/50, 5 gallons of 110 fuel mixed with pump premium (only from new or trusted store that has clean tanks and assuredly cycles through premium fuel.) I have found bad premium in the past from stations that don't sell it much and it gets old and gummy. It is actually easier to get fuel than avgas here. They started tracking tail numbers and logins to activate the pumps, and it's further away. Link to comment Share on other sites More sharing options...
