#191 of 284 2005 ram with 29000 miles by byrdsram Sep 11, 2007 (6:24 pm)
I have read many reviews about fuel mileage and can not believe that the numbers are so low. I bought a Ram with the HEMI and installed the K&N cold air intake #57 series (the #77 series in the polished metal conducts more heat and does not increase horsepower as much) and have seen my fuel mileage go from 18MPG average to as much as 22mpg on the same stretch of highway at 50-55mph according to the average on the truck trip computer before and after. I have calculated the fuel mileage in the past and the computer is very close to the actual mileage. I got the idea of the K&N from a guy in a camp ground that was pulling a travel trailer that was over the weight rating of the truck (7800lb.s according to Dodge website for the 5.7 with 20" rims)his was over 8000lbs and he said he has pulled that trailer through the mountains with no trouble at all. I have not pulled my 6000lb camper yet after installing the air filter but I will in about 2 weeks and will report the outcome. I have read reviews that said the K&N air filter would be a waste of money and if you wanted to save fuel then you needed to pick another vehicle. I also read that someone claimed to get 5mpg better, I think that is wishfull thinking but after getting an average of 3mpg better I think this may be possible with the right conditions. I have just ordered a Flowmaster 50series HD muffler after talking to the tech department at Flowmaster and the person said that any other muffler would decrease the horsepower and I would be better with the stock muffler since it was so good. The 50 HD was designed specifically for the HEMI. I already get 10mpg pulling my 6000lb trailer and I hope to get to 13+. If anyone has any experience pulling this kind of load please let me know. Thanks. Replies to this message: jasperpooch (Sep 13, 2007 9:04 pm)

Replying to: byrdsram (Sep 11, 2007 6:24 pm) Grab This By The Horns!! I own an 05 2500 Quad Cab Dodge Ram. It is a 2X with the Six Speed Coffee Grinder Tans. This 375hp 610ftlbs of torque 5.9 LT Cummins has made me a believer. I bought this with the absolute need for a 20MPG rig. Check this out folks 23 City, easily gets 25.5 Hwy and that is at 70-75. I have seen 28 MPG on a trip through the Cascades, K-falls, Susanville, and Reno to Las Vegas Loaded. Elevations of 300ft. to over 7,000ft were encountered. I just got a 39,000 mile service. And the salesman that sold it to me wanted to buy it on the spot for more than what I paid for it. (I think he was kidding about the price!) The service mechanic said I needed a new Air Filter. Just what I had been waiting for: (the justification to purchase a new filter), more specifically a True Flow System. Keep in mined this rig has a totally stock chip and CPU. Should I expect to get more on the MPG? It would seem to be unrealistic to expect any more. But we are about to find out just how good the True Flow System really is. I will keep you all posted. If anyone out there has a similar rig please share. Oh! For all you Hemi Guys out there.. Tacoma, WA to Reno, NV to Las Vegas, NV up the 93 to Boise, ID and Hells Canyon finishing at Spokane, WA. That is 2300 miles pulling a 30ft Travel Trailer. I got a Solid 15 MPG in fact make that 15.3.

Just an fyi with those of you complaining about economy, Dodge engines are known for being tight. They are not really broken in until about 40K miles. My brother's '05 Ram 2500 with a Hemi only increased in fuel efficiency after 40K. He gets about 19.5mpg on hwy at 63-65 mph. My '01 Grand Caravan ES (3.3L V6) did not attain its best efficiency until it had 43K miles on it in 2003. I was in the mountains of Pennsylvania and finally (at 65 mph) was able to get 24.5 mpg. Prior to that, fuel economy, unloaded on the highway was 19.9 at best! Just so you know. I guess they build their engines with harder rings/etc., to last and with 205K on the minivan, it hasn't missed a beat!! Replies to this message: dustyk (Sep 17, 2007 6:58 pm)

Replying to: mek0123 (Sep 17, 2007 4:04 pm) Contempory Dodge truck engines are built exceptionally tight, in fact tighter now than many Nissan and Lexus engines. New Mopar tolerances are:   Wrist pin 0.0004 (4.7), 0.0003 (5.7)   Piston-to-bore 0.0014   Connecting rod bearings 0.0006   Main bearings 0.0008   Camshaft bearing clearance 0.001   Valve stem clearance 0.0028   Piston ring pressure = 16 lbs.   Compare these tolerances to Ford and GM V8s. The real killer that contributes to long break-ins on Dodge motors is the piston ring pressures. Typical values are around 6 lbs. nowadays. Low ring pressures are used to reduce friction. On newer GMs they are 2 lbs., which is why they get good mileage out of the box, but also are prone to piston slap and oil consumption at higher mileage.   My 4.7 was not fully broken in until about 50K. That's when the mileage really started climb. Hemis are pretty much the same way.   Regards, Dusty
#195 of 284 Mileage help by minardi Sep 18, 2007 (9:00 am)
My '07 RAM 1500 4X4 Quad cab w/HEMI has P275/60R20 tires(Goodyear Wrangler HP's). When I picked up this truck, tires had 40 psi(cold). They are rated at 44 psi for max. load. Door sticker recommends 35 psi. I decided to split the difference and go with 38 psi, fearing that my gas mileage would go down the drain if I dropped to 35. Anyone out there find a pressure range that gives a good balance of handling and mileage? I've been somewhat satisfied with mileage so far(16-17 70-73 mph), but always looking for improvement.

Replying to: minardi (Sep 18, 2007 9:00 am) I over inflated a set of tires on my last pickup and found once you get over the maximum rated pressure of 35 psi on passenger tires, I didn't see any improvement in fuel consumption. It did make the truck handle differently and the braking was a little squirrely.   I ended up going back to 35psi.   Regards, Dusty
#197 of 284 mileage dropped from 14 to 9mpg (05 hemi) by badd63 Sep 26, 2007 (8:51 pm)
First, I must say I love this truck. I am an “old car guy” so I really appreciate the modern conveniences along with the power of my Ram. It’s an 05 quad-cab, 2wd, AT, 20k miles.   However, after about a month of ownership, the engine light went on—the dealer “fixed” it; then it came back on again in a couple days—the dealer “fixed” it again (I think they put in a new ECM). The only thing they told me was to make sure and run premium. Before the “fixes”, my mileage was about: 18 hwy, 14 city. But after, it dropped to about 12 hwy, 09 city.   My wife mentioned it to the dealer at the last oil change but she felt they just dismissed her, and offered no input after saying they would “check it out” during the oil change.   Last weekend I put on the K&N intake(57), but it did nothing for mileage. I am now thinking of trying out the Hypertech Max Energy programmer that claims a 2-5mpg increase—hoping it would not only improve nominal mileage, but “fix” the issue if the dealer programmed the computer to run richer for some reason.   a) does anyone have experience with gas mileage improvements w/programmers? b) Anyone have any idea what the dealer would have done to impact mileage so much?   Thanks!

#198 of 284 Re: mileage dropped from 14 to 9mpg (05 hemi) [badd63] by dustyk Sep 29, 2007 (12:09 pm)
Replying to: badd63 (Sep 26, 2007 8:51 pm) Gas mileage is highly dependent on driving style. My son averages 14-15 in just-around-town driving, about 17 on the highway towing with his '03 Hemi RAM. However, just like his other vehicles I can get better mileage driving the very same vehicle.   Assuming that your driving style has not changed since the dealer made the repair, your 9 MPG city, 14 highway is definitely not right for this truck, even though it takes a long, long time to break the Hemi engine in.   Everyone I know gets 14 or better with their Hemis around town, and most better than 15. I was with a friend one weekend and he managed 18.5 on a highway trip and that was doing the speed limit (65 MPH).   I'd say something the dealer did wasn't right or there's something else wrong.   Best regards, Dusty Replies to this message: gpino (Feb 21, 2008 8:45 pm)
#199 of 284 Re: Help! just purchased a 2006 megacab! [bigdave4269] by lady4032 Oct 09, 2007 (2:33 pm)
Replying to: bigdave4269 (Feb 12, 2007 5:37 pm) I am assuming the mds system is where the motor runs on only half the cylinders.If that is what you ment the mega cab does not have it because of the weight of the truck.They are so much heavier than the regular quad cabs they would be in and out of the mds system.I was told by a dealer when i purchased mine

Replying to: c130herk (Jun 15, 2006 2:56 pm) I also have a mega cab and would like to know if you did anything to get that kind of mileage. Replies to this message: fueledup (Oct 29, 2007 3:54 pm)
