Stepping Out With My Own Numbers

1425 to 1500 depending on load, weather, and road conditions. I focus on keeping my boost under 8 lbs at cruise.

 

I turn the same, but my boost hovers around 10-15. Problem with the turbo?

 

probably not. How heavy do you run? Headwinds? Hills? Lot of factors at play. But the one constant is your boost gauge might as well be named fuel burn gauge. The more boost directly relates to more fuel burn.

Every load and day is different. In order to keep a low boost i have to adjust my driving practically hourly.

 

It's all over the place. I am trying to stay as light as possible. The heaviest load in the last 2 weeks was 30k. I have stayed mostly on flat land, Cruse at about 63.
I did just get a PM last week that brought me up to the 5.7 mark. I may also want to focus on where I buy fuel.

 

I've been told I'm crazy but every time i buy fuel at loves it knocks a full .5 off my mpg.

 

Think of it this way......
Your engine burns a set amount of fuel naturally aspirated (0 boost). For every 14 lbs of boost you burn almost %110 more fuel. So at 28 lbs of boost you burn almost %210 more fuel than if you are running at 0 boost.

Another way to look at it is your engine is around 800 cubic inches... at 14 lbs of boost you have an engine that is equivalent to 1600 cubic inches. At 28 lbs you are using an engine equivalent to a 2400 cubic inch engine.

 

I went to SLC, UT and came back. Winds, Winds, Winds + 44 000 lbs loads both ways.
The last month I averaged almost 7.00 mpg staying east of Mississipi River regardless of weight. I went West this one time and it dropped the average to 6.6! I burnt 500 gallons for the round trip.

No need to mention that 40K lbs is a staying alive necessity on I-80 in WY during this week.
I went through there Larmie - Rawlins, WY section over 1000 times maybe and never saw that many trucks blown over.

 

Yeah I remember going out west a few times on 40 and 80 in a company truck years ago. Always seemed like I'd get terrible fuel mileage going west into headwinds. Sometimes as poor as 5.5 mpg in a truck governed at 66 mph that normally got 7 mpg in,ordinary normal conditions running regional. Just imagine all those suckers running cheap freight coast to coast fuel is the one cost they really need to control the most and they will always get screwed on that one way too.

 

6x2 will have hard time in winter docking fueling parking etc.
