what kind of fuel mileage can i expect with the truck in my sig? its bone stock other than the few things listed below. right now im getting about 12.5 average since its been cold around here in oklahoma city.

 

Howdy. What a SIG??

Thanks

 

what is you mileage when it is warm??

 

sig or signature is bottom of the post where it lists the persons vehicle and set up

 

12MPG sounds a little low. Possibly because of the gears.

I would think you should be somewhere between 16 - 18 for this time of year.

 

No winter fuel sold in OK at this time of yr.... unless you buy at truck stops?
Wal-Mart sells #2 yr round here.... better mileage.

Even with 3" lift and 410 rear end, you should be getting 15 around town and at least 18 on hwy..... unless you're doing a lot of warm up idleing?

Hmmm I do plug it in most nights and it idles 15minutes or so, last summer I never saw more than 15.0 even on mpg... Getting 18 would be awesome I change the fuel filter every other oil change.
What other things could reduce mileage??

 

I get around 12 or 13 but my truck weighs around 12500 empty with welder - dump bed, crane etc.

 

Im in maine I have 4:10s and a set of 285's on my truck im getting about 15 now and when i run summer fuel im up around 21 to 22 im sure the 15 is a bit low due to warm up times. what do you have for tires?

 

What RPM are you shifting at ?? And what RPM out on the road ?

Best mileage is normally obtained around 1800-1900 RPM .

This is a diesel not a gasser no need to wind it real high in every gear also how heavy is your foot on the skinny pedal around town ?
