I get my VP-101 unleaded from a local Arco station is that junk too...........
That's not pump gas.
And as far as knowing the percentage drop like MrP said, that still doesn't tell you WHAT they dropped, just how much of it
On the drop sheet they have to show what was dropped
but it will say 87 octane normally.. not very often
will you see 89
My point was, that doesn't tell you what BLEND they dropped in there. Because fuel blends change seasonally. 87 octane is not the same fuel year round. Most guys I know who bracket race with E-85 check it with a hydrometer religiously, or the car runs all over the place, at least around here
