The one time I got 85 octane was in West Windover, NV, since I had
been driving in mountains all day I was figuring that I would start
getting better gas mileage going across the salt flats. With the lower
octane fuel I got 13 mpg, where I was doing 17.5 earlier that day. I
put in 92 octane in SLC and over the next 300 miles I got just shy of
18 mpg. I'm sure the computers can compensate but my truck, with a
1000 or 1500 lb payload doing 80 mph down the freeway in the mountains
could sure tell the difference.
