I am happy at 65mph maybe 70. I always wonder about the BBR O/Os that blow past me at 70 plus... They must have alot of money for fuel...

It's important to factor your ratio, tire size and torque curve. My old Werner FL classic does best at 64-66 mph for fuel mileage. I just get up a little earlier and keep the left door shut and I'm parked for the night b4 the truck stop fills up...usually. It is set wide open, but I rarely go over 70. I would rather have the extra money than get there 1 hour sooner.

hogan truck supposed to be 65 mph, but had it tweaked at the hogan facility in fontana california to go 68 mph, makes a huge difference.

My truck is governed at 80. Most of the time run about 72 depends where I'm at. Usaly getting between 6.8 to 7.8 mpg.

Let me guess!
You either running about empty, or always on a flats, no traffic, and wind is always coming from the tale?
Tell me i'm wrong :P

One more option, you've miscalculate your fuel mileage. :roll:

I only got 6.6 mpg for the best, with lite load, and a terrible 4.9 mpg weighing 79,225, going thru to CA from St louis

depends, i rarely go over the speed limit by more than 5 mph. On a side note, where are you guies usualy. eather most of you are fibbing or I never see you all on the road, most ppl fly past me like I'm standing still, even at 66

I'm elusive, but if you look hard enough, I can be found.

Right now I'm up by Boston, doing a 4 day unload.

I run 71mph in my rental truck (rental). In OK< I"m doing 71mp, in TN I'll prolly be doing 71mph. :lol:

My truck is governed at 65mph. I have to goto court again next week about a speeding ticket on I95 in delaware.
