Big Hood or Aerodyne Hood ? What is the diffrence in fuel mileage?
What are some of you getting for MPG and what kind of truck are you driving and type of trailer? My old truck I average 5.8 to 6 with a 2001 Pete 379 ext. hood 475 Cat 13spd 3.55's pulling a 2006 Reitnour 48' Flat.

The company I am leased to have over 100 of 07 Pete 379's with 475 cats and 10 spds and they have 3:36 rears, they have drivers averaging 6. 0 to 6.2 I have talked to some other fleets that are running the same trucks and cat engines and they are all doing around 6.
I hate to see what you are going to get with the new one

I was getting 6.7 all time average(962,000) with my 550 3406E CAT, 13 Eaton, 3.36 rears, 24.5 lp tires, in 1996 Volvo(old stile, like WGMC). 53' dry box I'm getting, 6.85 all time average(235,000) with my 475 Cat Acert, 13 Eaton, 3.55 rears, 24.5lp tires, in my 2005 KW T600. 53' dry box. I wish, i'd specsed it with 3.36 rears, and 22.5lp, would gain probably another 0.2-.3 mpg! :roll: As of to "aero" or "long", the faster you'll run, the more is difference. Identicaly specs 379, and T600, (dry box), at 75mph, i'd guess 0.8-1.0 mpg difference. Btw, it's a whole new learning with Acert, it's very unforgiven!

You will normally get better fuel mileage with a aerodynamic truck than a non aero truck. I am amazed at how high the fuel mileage that some who have posted are getting. I never recall getting more than 5 mpg on my Peterbilt. :?

I used to get around 5, pulling a sand trailer,(120,000) local driving. Stop and go all day. That was a W900 with a 550 Cat. My current ride, Freightliner with C-10, is pretty crumby, 5.2-6.5, all light stuff, 60,000 and under. I figure you road guys (80,000) with all that highway driving, have to do better, 6.5 to 7, or 8.
