BLUEKNIGHT911
Sadly Passed Oct 2024 - RIP
I do exactly the same as BK911 with one exception. I fuel up at 150 miles, give or take a little. Like ARtraveler, I also learned a good lesson that I'll never forget. A nice rancher's wife helped me out and gave me gas from one of her tractors.
As long as they follow the EXACT SAME FILL-UP PROCEDURE EVRY TIME then the results will be the same, ie. the EXACT mileage for that fill-up will be known .... and that info is vital to know your avg. fuel MPG's .....Mike :thumbup:
