Shell V-Power test

[n0rt0npr0]

I don't know how any two refinery's could produce the same performing base gasoline's

I am implying additives and ethanol percentage produce significantly different FE, and I've been keeping a list of vehicles/engines that are driven that claim otherwise to find any sort of correlation.

I wonder if this could be tested by staying with one cut-rate brand or station for a while?

That's part of the way I solidified my belief.

You should fill your tank up right before and right after your vehicle gets repaired.

I wish that had occurred to me. I did keep track of the distance they test-drove the car, though.

Got a little surprise... I unplugged my ScanGauge and took it with me (since they would be using their scanner, plus I didn't want them playing around with my SG and maybe clearing some figures). Unfortunately, while it remembered my mileage and gas figures over the course of the day, it forgot everything else (engine displacement, tank size, etc.)

I think I got everything set back as it was, but FE seemed unusually good on the way home (won't know for sure until I drive one of my regular routes). Maybe it was my imagination, maybe the SG calibration is still off, or maybe the oil change and other maintenance are helping things run more efficiently. (Others say their numbers go up right after an oil change.) We'll find out on the next tank fill, but it looks like there's yet another variable in the mix.
