Part 2 of gas mileage from different gas station

[dave1068]

Well gang,

Part 2 confirms there must be something in that overpriced $3.34 a gallon of 87 octane. I usually make it to about 320+ if pushing it..  When I rolled into the gas station I fit 12.5gallons. (i think its 12.7)

I can't use 87 in my '16 V7 it knocks bad, but I find if I fill up (93) and ride out a tank full I get better mileage but leave it parked a day or two I'll get a mile or two less per gallon.  Also I get better mileage with non ethanol gas (93).

Also I get better mileage with non ethanol gas (93).

That's typical - one needs more ethanol (by volume) to generate the
same power as a given volume of gasoline. Non-ethanol gas gives
better mileage.
