07' Quad Cab, 2wd, 4.7L, 20" wheels - I average 16.5 - I'm very conservative with the go pedal, tire pressure is watched closely and keep the speed around 65. Bottom line, these are big trucks that get terrible mileage!

 

just went down route 66 and averaged 32 mpg with a 2.0l engine.

 

I agree on the cruise control and thats the samething that I do. I also keep my TB clean (which is an area most people ignore) and it makes a hell of a difference in gas and performance. I Seafoam through vac tube every 25k. Tire pressure is another great factor. I have factory 17's and I use tires thats rated 50 or higher. That way I can keep 40-45 psi with great mileage. If I'm towing than more air, of course. It only rides like a basketball at 70 or 80 depends on the tires.

 

I just purchased a 2003 quad cab 4x4 1500 with 8ft bed, 20" rims, and hemi. I'm only getting between 8 and 9 MPG in city. doesn't seem to matter if I baby it or hot rod. it has 82K (miles) on the odometer. The truck came with a K&N intake and obnoxiously loud exhaust. Seems like I should be doing much better. Freeway at 60 mph I'm only able to push about 11 mpg. What could be wrong with my hemi? no trouble lights on the dash and it seems to be running fine.

 

I just traded my 06 2wd 1500 with the 4.7 with 52,000 miles for the same reason. averaged 11 Mpg all the time (hand calculation)

couldn't afford to keep feeding it.

my new truck is averaging 24 Mpg's (hand calculated ) with much more spunk then my Dodge had.

but in all fairness, I think something was going on with it. it used to get 16 when it was new.

 

I get about 10 or 11 with my 06 5.7 qc. Ever since went to a 33 to 35, its gone down 1 or 2. Had a new motor put in her in july, 28k on it. She runs like a champ. This past Saturday, drove about 200 miles to and from me to a different county, only burned a little over half a tank so I was surprised to say the least lol

 

What did you buy?

 

04 2500 4x4 with 35s, I'm getting between 9-11mpg

 

2002 1500 2wd 4.7, 33s w/ 2 inch level- 15 mpg

 

I've been doing a bit of fuel experimenting. I started using non-ethanol gas in both my truck and my Jeep about a year and a half ago and almost right away started seeing a solid 2-2.5 mpg gain in both vehicles. The problem here is that I have one station about five miles away and one about twenty that I know of who carry it. Get away from home and they are few and far between and even with the database of stations that's available, many times it would take me miles and miles out of the way to get it. Couple that with the fact that the small independent by my house doesn't take credit cards and it's a downright PIA getting it all the time.

So I stopped getting it and within two tanks lost the MPG gains I was seeing. I had been using a product in my yard equipment gas for a couple of months on the advice of a friend who owns a landscape/yard care business that basically takes the ethanol out of fuel. I was having a big problem on seldom used equipment with the ethanol eating away primer bulbs and fuel lines not to mention carb gum up issues. The product worked wonders, so I started using it in my ethanol gas about three months ago. By the third tank of gas I had my 2 mpg gains back in my truck and closer to 3 mpg in the Jeep. A recent trip with the Jeep up to my farm got me 22.1 mpg for the whole 900 miles I put on the Jeep over the three week period I was away, beating my average of 18.5 mpg over the past two trips including 17.8 I got last time up in July.

I've got one of the guys who co-owns my small piece of farm property using it in his '98 Chevy Z71 and according to him, he's seeing close to 4 mpg gains on his fifth tank with the additive.

The product is called Star Tron and is made by Starbrite, a company who has been making fuel additive for marine applications for decades. It's available in multiple concentrations. I purchase a super concentrated 8 oz. bottle that treats 128 gallons of fuel from the marine/fishing department in WalMart. It runs about $8 a bottle so spread over 128 gallons of gas we are only talking about a buck and a half per fillup. Obviously with the gains I'm getting the product MORE than pays for itself in fuel savings, not to mention my vehicles idle and run smoother and the product is a two year fuel stabilizer.

Try you a bottle and see if by the third or fourth fill-up your truck isn't running smoother and you aren't seeing better fuel economy.
