With the high compression heads I run I need to run 94 octane fuel. There is only one company that offers it. Husky/Mohawk.
I mix it up once and a while and go to 4 different stations to get gas.
Two station in particular I find the truck pings whenever i use that fuel, almost like it's a lower grade. Now the thing I noticed about this set of pumps is it's the only two of the 4 to have the Multigrade pumps, (3 grades out of 1 nozzle).
My guess is that there is still the low grade fuel still in the lines before the Premium grade starts to flow out. How much i don't know. Kinda a rip off when you think about it. Depending on how much fuel is still left in teh line from the last pump. Out of the 40 liters or so how much is the lower grade, assuming that is what was pumped before you got there! So you essentially pay Premium price for 4 liters of residue low grade fuel that comes out first. I know it's not even amounts to a buck but I notice it in the way my truck runs.
Anyone else wonder about this? Guess that narrows me down to 2 stations to fill up at.
