Replying to: 98ddgram1500 (Jan 08, 2008 3:35 am) I have 2007.5 Mega Cab 6.7L 2500 4x4. I installed an Air Raid cold air intake system and got 1.5 mpg improvement. I next installed an inline Fitch Fuel Catalyst and got another 2.5 mpg. Total cost approx 550.00. My mileage now stands at 15.5 city and 19.5 hwy. at 75mph.

Any tips on improving mileage in an '07 1500 Quad Cab with 5.7 Hemi? Truck got decent mileage when new last summer. Seems to have gotten worse with age(approx. 20K miles later). I do mostly highway driving and it doesn't seem to matter if I drive 65 or 75, I average about 13 mpg(calculated, not using truck's computer).

Replying to: minardi (Aug 27, 2008 10:52 am) I also have an 07 Ram 1500 HEMI (that thing got a HEMI?) and have got 13.2 mpg (worst) and up to 18.6 (best) since new. I have approx: 11K miles on my RAM now. Usually averaging just under 15 mpg (actual, not computer read-out which is not too accurate). In the summer here in TX, its hot as he!! so I run the AC full time resulting in a 1 to 2 mpg reduction in MPG. I also went with a freer flowing air filter (judge is still out on this) and recently went to synthetic oil (after 10K of mileage on convention dinosour oil). I do 1/2 & 1/2 City/highway and drive like an old-lady. Its sad you have to drive a HEMI like that or else you pay out the wad for fuel. Put your foot into in and mileage goes WAY down. I noticed about a 1 to 2 MPG increase after the filter & oil combo getting me back to where I was prior to running the AC all the time. In the winter overall mileage should improve but a cold engine gets less MPG so only time will tell. 13 MPG seems low bro but I dont know your driving habits and other MPG / environmental factors. Let me know what you find out if you get any good pointers.   Ski in TX

Replying to: 04ram1500 (Jan 07, 2008 8:56 pm) I have done several things to my truck and actually get very decent MPG in town on my 2003 Quadcab 4.7.   1. Superchips Programmer. I have used both the 87 octane Performance and the 91 Octane Performance mode and settled at the 91 (I run 93 Octane and while it costs more at the pump I get it back plus some in MPG and unbeleivable difference in HP) 2-3MPG   2. Flowmaster Exhaust. I just put in a Series 50 it is not as loud, less cab resonance and still has free flow. Sound great and helped my MPG by about 1mpg   3. I have switched to Royal Purple in both engine and Transmission and soon rear differential. I was told it helped... I am a believer now, been running it for about 10000 miles and have seen as much as 2.5 MPG just in changing to Royal Purple synthetics not to mention it runs alot cooler even with the performance mode.   4. New Plugs. Stick with the factory type plugs, there have been lots of reported issues with Platinum and Iridium and other plugs both in less MPG and siezing in the block.. Dodge spend a fortune in R&D to find the right plugs and temp for your engine and I doubt you can do better.   5. I am ordering a CAI. Keep in mind not all intakes advertised are true CAI more are short ram style. Dodge acutually has a true Cold Air box but the "air hat" and the connection tube has poor airflow. I haven't heard about issues with O2 sensors per se but the new Dry filters offered by the better CAI manufactures are worth the $.   6. Fitch Catalysts truely do work I have seen it but haven't forked out the $$ for one ...yet...   All in all. I have gone from an average of 12.5- 13 MPG in city to 16+ MPG in city with this old Dodge Quadcab...when I can keep my foot out of it. Hard to do with all the new found power. I never go below 13.5 in town now even with my foot in it and pulling a trailer. I have 93000 miles in it and have had good luck with it. I had to change the TPS and the Cam position sensor... about $50 total and 30 mins of work. Not bad considering the miles I have put on it. I don't do much freeway driving these days other than vacations and such, even then I get ~20MPG loaded with camping gear, 4 wheeler or motorcycle and a load of kids.

Anyone had any "real" luck improving mileage with CAI's like K&N's? If they even got 2 mpg better, it would pay for itself in about 6 months or less. Been doing a lot of reading(mostly on K&N's web site) and it sounds positive. BUT, I also talked with a friend who's heavy into drag racing who advised against it. He feels that the filters are too porous(in order to maximize air flow) and that you'd have to perform very frequent oil changes to keep your oil clean(if you want max. engine life). Some guys have also had a tendency to "over-oil" the reusable filters and screwed up engine sensors, etc. So now I'm hanging, and getting a max. of 15 mpg highway 75 mph. I've got the Thunder Road pkg. with 20" wheels, etc. Been keeping the tires at 38 psi to try to squeeze a few more mpg out. Replies to this message: stanoski (Nov 12, 2008 2:44 pm)

Replying to: minardi (Nov 12, 2008 12:17 pm) I have an 2007 RAM 1500 with the 5.7 HEMI MDS. All I did was change the stock air filter with a K&N filter (filter only, not total cold air intake) and nothing (no improvment) on gas mileage. It may be breathing easier, but that did not translate into more MPG's in my case. Save your $50+ bucks (buy beer instead. At least you will get something out of it) and stay with the stock air filter in my opinion.   What did help was going from dino oil to synthetic. MPG went up 1 to 2 MPG on my HEMI on the first oil change.   Ski in TX

What type of synthetic did you use, and what viscosity? I've been running basic dino Valvoline or Pennzoil 5W20(as recommended). I was reluctant to make the switch to synthetic, figuring that if it didn't give any mileage improvements, I was stuck using it forever. At 7 qts. a shot, it's not cheap!

Replying to: minardi (Nov 13, 2008 8:54 am) I ran dino oil until 10K (dealer stock) then went to Semi-synthetic (Castrol) for 5K then moved up to full-synthetic (Mobil 1) after that. All 5W/20 as Dodge recommends. I noticed an increase in MPG with the semi-synthetic and on the full-synthetic. Too close to tell between the two.   I also noticed an increase in MPG (1 to 2) without my AC going. Of course thats hard to do in the summer in Texas. Watch for it on sale and buy the BIG 4 or 5 qt bottles, its cheaper that way rather than single quarts. Maybe just go up to the semi-synthetic at first as it is more cost effective than full-synthetic and you might get a MPG boost as I did with it. At least its worth a try. Good luck bro!
