In the old days I ALWAYS ran a rough mix of 60/40 Unleaded pump/AV gas...Maybe a straight 12 gallons of AV gas Sat night...off to the drags Sun morn...[12:1 comp] Always ran purrrfect! Last time I ran AV gas was two summers ago ..same mix [11:1 compression] very good!
But now I'm too lazy..the truck drops off the drum of VP 4:1 [pump/av]in the L-78 1:2[pump/av] in the L-88[ or straight if it's off to the drags...
