Well, the stalling problem on the van only happened once. I had the van again yesterday, and it was at 1/8th a tank. I went and filled it up for my wife.
And I just can't resist mixing in a little E85! I'm an addict.
I got 5.067 gallons of E85, 13.769 gallons of 87, and there were 6.134 gallons from the previous tank.
That works out to about 26.6% ethanol in the tank. A little more than last time.
Using E85 saved a whopping $2.50 on this tank.
Mileage was maybe a mpg or two less than on 87, as you would expect.
