I have W900L with a 550 acert 13 speed 3.55 rears 22.5 tires. I average 6.8-7.4 I drive 64-65 mph. Just under 1500 rpm. Installed fleet filters. I drive mostly to Colorado , Washington state. Not bad I'd say for up there.

I have a 2005 w900 550 alert. Free flow exhaust and fleet filters with a 13 speed tranny. I'm averaging 6.8-7.4 @ 65 mph. The last trip I took to Washington state I got 6.8 mph. Also coming across Texas on I-20 set my cruise on 80 mph I got 5.5 mph. I have 3.55 rears also. That's the next thing I'll change.

Mine is a 99 379 with a 3406 e. 10 speed, 3.90 rears and 24.5 tall rubber. My lifetime average on paper is 6.34. I pull a flat, hauling oversize, mostly steel, always heavy in the south. I run 60 - 65 mph most of the time.

Mine: 94 Pete, 500 CAT, 15 over and tall rubber. 6.5 Wbnd hauling 32,000 Balt to Sea. Ebnd with 48 K 7.25 and thats running 5 mph over the speed limit in every state where it was under 75 except NV where it was already 75. I figure, if you run 5 MPH over you gain 22000 miles a year over a 55 mph truck and it sure doesn't cost that much so 33% of that was more profit over a 4 year period. The bad news is the IRS wants their part.
