MPG in the Real World

'98 FLD120 with a van @ 70K average gross. 8.34 MPG US average from April till July

 

You have a load like this n you couldnt break 7 MPG in 'very favourable conditions'?? Yer ol century aint as good as you say or you are not as good as you say...?

 

Why argue or keep running around in circles over the same subject. Let them do 20 if they say so.
Not all of the trucking business is conducted the same under the same conditions/equipment/regions/weight limits and so on.

Now instead of labeling "real world" just try instead "Most Industry standards" we all know is 70k# up to 80k#
We all know is 22.5 tires
What we dont know for sure is trailer, tires (duals- SS) and other equip specs along with weather, and regions run.

Having commented on that, I'd like to contribite by saying I've run best without cruise control and an un-governed truck as to MPG rather than a governed truck that tops at 65 mph and engaging the "automatic pilot"
My best numbers ever were 8.4mpg.. It is the only time I ever hit more than 7 mpg in a 2000 century, N14 with a 10 spd. Duals. Flatbed. 20k#

Saving fuel is as much as education to your driving as experience. As some one stated before, dont push the engine.. let it build up power. Just like using an electric jigsaw.. you dont push it, let it do its job.
No matter what kind of specs you got, no matter how much weight you're carrying, you can burn 5.5 mpg empty if you drive it like you stole it.
Now I'd like to ask the thread keeps on subject and if possible an uniform way to answer
Id present this idea

Equipment
Weight
Run
Weather
And MPGs

 

I don't understand your question/ statement and I don't recall ever saying me or my truck were anything one way or the other.

The old Columbia is what it is. That picture/ load was Revelstoke BC to Easthampton MA. @ 75,000 all loaded miles.

 

4.7 to 5.1 mpg, depending on where I go. That includes approx 3 hrs a night running PTO to unload. I run central PA(lots of hills). Grossing 80k when loaded. I run a western star 4900 with a 3406e, 13 SPD, 3.42 rears. My last truck, spec'd with 3.73 rears was averaging 5.6. Hopefully once the new truck gets broke in things will improve. Oh BTW, I run 67 mph

 

I think that just about everyone here is right. It all depends on your individual driving style, your truck, the load, how much deadhead etc. The biggest factor is you. I really don't care to be honest, some people take life too serious. Just know your numbers and don't haul cheap freight. If you drive a company truck and your getting your fuel bonus then your doing it right.
