im an idiot so does anyone know how to post a poll so i can get an idea of what everyone is getting gas mileage wise? im getting 15mpg on a good day. just kinda wondering if thats normal.

 

06 auto trans 373 gear 18to 19 empty 8to9 towing,50% drop when towing

 

FYI, we don't get GAS mileage but we do get fuel mileage from a diesel engine Right now with winter fuel and cold temps I get between 14.5-16 mpg combo driving 75% hwy 30% city. Last summer I would get between 18.5 and 20.5 mpg on the Hwy empty and about 15.5 in town.

 

17 in town, 21 hwy...And I'm happy with that.

 

I get about the same as madhat, if I run my propane and drive 65 on a highway Ive got upwards of 25

 

Are y'all hand calculating or using the over head?

I don't think it's physically possible to get 25 mpg with a 7500lbs truck. Unless your coasting down hill. A very LONG hill.

I'm averaging right at 15.9 (hand calculated) right now driving about 75% highway.

 

I am getting 18.5 - 19.2 hand calculated (and kept in a spread sheet) with 80/20 highway/city with my truck in sig. Some people are getting better than that with different boxes and programmers.

 

13-14 City don't know highway mileage yet

 

as for mpg i don't know, but i go about 600m on a tank. mixed drive empty

 

guess it depends what you drive 27, not 17, 27 only in town hand calculated, hwy on the other hand is like 20 hand calculated.

 

Empty just truck 18-21 hwy
Loaded with empty trailer 13-15 (7,500lbs trailer empty)
Loaded with total weight way to much... 9-13

All figured the old fashion way!!

 

8-10 mpg city right now its so cold I have to let it idle for 1 hour in the morning and 30 minutes in the afternoon leaving work

 

15-17mpg for around town. 21-23mpg highway. Did get 25mpg once.

I've averaged 15 city and 19 highway hand calculated through 3 tanks of fuel now. I just did put the new tranny and fuel system in and the truck drives like a completely different truck. So far i've gone 140 miles and the gauge hasn't even moved.

 

Hand calculated out too ever last # on the recipt and odo. Last tank was 18.42mpg. worst tank ever was 16.77mpg(some plowing and driving with the plow on). Best tank ever was 22.48.
