Gas mileage is going up

1500 miles on the truck and it seems to have taken a pretty good jump. I was getting around 17 on my commute and now I’m getting around 22. It seemed to increase pretty suddenly too. I took a decent trip with it and since I got back it’s jumped up. Computer? Breaking in ?

 

Yes, breaking in my mileage improved.

 

That funny I got Great mileage when new over 20 MPGs then I put on more off road tires with the Sema wheels & it dropped to 15 MPGs at 4700 now

 

I've been getting garbage mileage since day 1 (a few months ago)....average around 15 with a mix of city/hwy. Up to about 1200 on the clock now and still waiting for anything close to advertised. Guessing this constant blasting of the AC here in AZ doesn't help?

 

Sounds more like a road trip, less stop n go driving will greatly increase mileage. I'm not sure about your area, but around here the metro has shitty ethanol added, but out an hour or so, going in to rural areas we'll find non ethanol, it's like winning the redneck lottery.

 

What I mean is my regular commute Milage has increased since having taken that trip. Same route as before.

 

Hey as long as it's going in the right direction!

 

Mine did the same, but its leveled off at an average of 23.5 mpg once i hit 2500 miles.

 

Summer mix of gas.
