i get around 19-20 with 31s and 3.73s.

 

I have the 05 L2 and I get around 19mpg. Whats weird is that I pulled my front skid plate off and I went up to 20 mpg. That makes no sense to me. Don't mean to hijack the thread but does anyone have MPG numbers for 4.88's?

 

after you pulled the skid plate, did you change your driving style? was that 20 mpg after just 1 tank of gas, or after multiple?

 

3 tanks and its hovering 19.8-20.1. before the best was 19.1. The only thing I can think of is that the air is slipping under the truck better instead of being forced down. Any ideas?

 

nope......

 

unless it is a weight factor...but i dont know how much they weigh......also did you get the gas from the same place each time?

 

No i did not get the gas from the same place each time. The skid plate is maybe 20 pounds? I don't think that would be a factor do you?

 

I filled up with half a tank left and got 22mpg on my 2.5l 5spd.........not bad considering my foot was in the gas a good bit, and we have alot of hills around here, and had the A/C on half the time. (heater on in morning, and A/C on in afternoon). All I could get with my old truck was about 12mpg if I kept my foot out of it.

 

I've always gotten about 16 mpg with mixed driving, I calculate the mileage on every tank. About 10,000 miles ago I switched to Marathon gas and Mobil 1 5w-30, now I average 18 mpg. I don't know if its the gas or the oil, or the combination, but those are the only things that have changed.

 

it is the gas.......and if you were using a 10w30 oil, then that would factor into it to because it was a heavier oil....some gas will give better performance than others...

 

I just calculated my gas mileage for this last tank of gas. I used my GPS system to determine how far off my odometer is. According to my GPS for every mile my odo reads I've really gone 1.26 miles. After doing all the math I found out that on this last tank of gas I got 18.235 miles per gallon and thats all city. :D Not to bad for 35s and 4.10s not to mention the 3.0

 

omg maby if i lift mine 8" with some 40's i cna get like 28mpg lol i dont get it my almost stock heigt truck gets worse then lifter trucks and bigger tires lol
