ive got the 4.7 and i get 13mpg stock well i got the fm and powerwire but its been the same since i bought it in november....and im looking for a good deal on a superchips but i want either the 3815 or 3865 also....

 

I've never heard of the seafoam or the other product really.
I might have to try that stuff.
And I would like to get my truck up to 5650 rpm a couple times a day. lol

 

I was just thinking of mileage over the last few days. I've always been a truck person, and I'm used to low mileage, stiff ride, etc.

However... I've also just realized/remembered something:
Both my '76 Chevy K20 with a SB 400 and '76 Ram 4x4 with a 361 got About 10Mpg on the flat I-10 freeway in Arizona. Take off the front driveshaft and get 12Mpg.

My last trip to the coast, highway + city + mountains was 10Mpg while pulling a ~6,500lb trailer. I also get 9-13Mpg in the city depending on if it's all short commute or if I make some longer trips.

I'd love to have 40 or 50Mpg in my truck, but I'm pretty happy with what I've got.

 

What kind of driving do you do on a daily basis highway and city?

Mostly city, but some driving in the country going 55 for several miles.

 

OK, thats why your using up more gas those short stop and go's is why.
I would just try taking your truck out for a good drive on the freeway and do about 70 to clean stuff out every so often.

Other than that I sounds pretty normal.

I average about 16-18. I don't know why mine is high compared to everyone else. Might be because its a RC? I though my overhead was wrong but i set my trip and calculated it out the same.

 

sounds about right

 

I didnt read all the messages, so forgive me if I repeat someone. But if your truck idles a lot, it will drop your mpg on the computer. in the summer mine says about 12.5 to 13, but in the winter, I let my truck idle and warm up so much its almost at 8. So you need to take that into consideration also
