This has been discussed many times in this forum and everytime it shows the same results,these are mine.
I fueled up in Indianapolis,IN last thursday night and delivered around Cincinatti,Oh on friday then back to Chicago to pick up a load for Brownsville,TX which I delivered on Monday,then up to Houston to pick up a load going to Chicago.
I never set the cruise for over 62mph and ran under 60 when in IL.
Total miles for this was 3,737,total gallons used 582.260 at a cost of $2,226.79 for an average of $3.824 a gallon.My mpg came out to 6.42,which is almost 7 tenths better than I usually average.
In real world numbers I saved 67.653 gals of fuel based on the same avg cost per gallon I saved $258.70 over 7 days.
It wasn't easy running 61-62mph in those 70mph states I will confess,but once you get into a groove and just ride it wasn't that bad and if I can put 258 bucks in my pocket at the end of the week I think I can handle it.
I would like to make a couple of observations about driving at this speed,I got really frustrated at other drivers and the way they pass slower trucks.I was pulling a flammable load and that made no difference to other drivers,they would tailgate within feet and what was really hard to take was how close they would pull back in front of you especially if it took them a little longer to get pass,you can guess the kinda carriers that it would take a little longer to pass someone going 62mph.
I would constantly have to kick off the cruise to back off and leave a little room between the truck that just pulled in front and myself.In my opinion they are putting me at danger by their actions,not to mention if a officer just happens to come around without seeing his actions I am in position to get a following too closely ticket which is grounds for immediate
termination from my job.
