Has anyone notice that there gas millage decreased during the winter months? I was averaging about 17 mpg during the summer and now am averaging a little over 15.

 

Very common, the winter mix used in your gas is of different chemical composition resulting in less mpg.

 

Aye, that in combination with starting truck lil earlier in morning and letting warm up, ect. I usually see 2 to 3 mph decrease....

 

I have been getting horrible gas mileage lately when I first got my truck it got 330 mi from a tank or about 15 mpg this tank I'm going to get under 250 or around 11-11.5 mpg's. My driving habits haven't changed and I even added a Volant CAI. I guess its from cold and letting my truck run in the morning. I'm ready for it to warm up!!!

 

Thats good to know others have noticed it also. Just wanted to make sure that there was not something wrong with my truck.
