How I got on to this foolishness, is one of my tractor buddies who comes for Sunday afternoon visits some times got me on to this. He said his truck, 1997 Ford 1/2 ton 4.6 litre with 600,000 kilometres on it, works better and gives better gas mileage and was cheaper to operate, on high test fuel. Ours here is 91 octane. This guy has his own heavy truck repair shop and keeps details of every thing.
Any way. I kinda said in my mind, ya ya, your pulling my leg on this one. But I figured I’d try it. And both last two tank fills, the mpg was up. So I’ll keep doing it and see. May just be a fluke.
Pretty good ramble,
Noel
