You won't increase enough fuel mileage if any to warrant the expense of that stuff. 6 miles to work. It doen't even have time to get any engine heat much less decent fuel mileage. PLUS your on winter blend fuel. Ride a bike either pedal or gasoline. Gas motors towing all get terrible "MPG. If its just a time or two a year live with it. If not get a diesel. I pull a 5000 5th wheel. I get 10.7 tops.

 

have you changed your spark plugs? The copper plugs burn out pretty quick.

 

Most all plugs on the market are copper CORED. Its the tip that wears. Factory plugs that come in these Hemis are nickel tipped.

I just finished filling up this morning before the blizzard arrives tomorrow, low and behold fuel prices dropped an additional .28 cents in 10 days, even more surprising considering it's less then a week away from holiday travels!

Do we have a MobileCares rep here as well? (lol)

 

I live in texas and I can never get over 15.5 mpg. I have a 09 Laramie Hemi crew cab with only 37,300 miles on her. Anything I should check or is this about normal for our trucks?

 

Depends - is that highway, city or mixed? I get around 19 with pure highway driving in the summer and 17 in the winter. In pure city driving it is more like 13.

 

Ditto... 09 5.7 QC

 

I guess I knew when I bought mine that it wasn't going to get that good of gas mileage. The sticker said 13/18.. I get about 11/14. It has flowmaster 40's, a K&N air filter and the predator programer on the 87 tune.. It's only got about 31k miles and i recently had the plugs changed. Wow, that was expensive. the labor was rediculous. Anyway. I'm pretty sure most of the trucks suck when it comes to MPG..

 

its pretty much all city driving.

 

I'm looking at a super chip 3865 flash paq. $200 used. Guy is going to program my truck right then n there to ensure its unlocked and works. Is this a good deal? Looking to gain some mpg for dd & power when I tow
