Replying to: 98ddgram1500 (Dec 26, 2007 7:06 am) Correction to my last message. I get 10.5MPG with the tonneau and 10.9MPG without it. The "Saves Gas" is a sales pitch with tonneau covers, and its false. Its been proven by mythbusters TWICE that they DO NOT help your MPG, they actually make it worse. The best way to go was the mesh airgate thing, but its too tacky to use, then second best was with the tailgate UP. the Tonneaus and the tailgate down or off were the worst ways, so put those gates back up. I use the Tonneau because of the New England snow/rain, but roll it up otherwise. |

Bought a 2008 Dodge Cummings 3500 after having four of these trucks before. The MPG is very poor compared with prior trucks, lost over 4 MPG both regular and towing. Bought a Super Chip and found that even the one made for the 2008 Dodge the #3808 will not tune the truck, they still do not have the right codes to do the job so I returned it. If anyone has had any luck with a computer tuner that works let me know. Thanks Larry

Replying to: wa4ko (Dec 30, 2007 6:59 am) 20.9 H/C ( hand calculated)  74mph. O/H (overhead) displays 23mpg. 22.2 70mph 18.2mpg towing 4500# flat car hauler over two 6000' passes from Vegas to LA at about 68mph A few observations: Tried a set of high quality 285/70/17 10 ply highway tires an mileage plummeted to about 17.5 70mph. Saved the 265/70/17 10 ply Michelin's that it came with, put them back on and mileage jumped back to low 20's. Amsoil was worth about .8mpg and a little better turbo response at small throttle openings. Mileage nose dives abruptly past 75mph. The 6 speed manual would probably allow me to cruise with LA traffic and not get MPG penalized so much. Tailgate removed makes no difference at any speed. Driving un-smoothly and accelerating in traffic off crusie control doesn't hurt mileage nearly as much as even the tinest hill. That's a lot of power to accelerate it but a bunch of weight to push up a hill. Test drove the 6.7 CTD with same equipment and mileage was nowhere near as good, struggling top get into the 20's at even 65mph. I like the equipment and trans in the newer 6.7 but couldn't accept the mileage difference. Wish it was quieter cruising and had a 6 speed auto, otherwise this thing is an utter gem.

Replying to: 949racing (Dec 31, 2007 12:11 am) I am glad you tired the tailgate, you need to see episode 43 and 64 of Mythbusters. Here is a quote from episode 64 "Tailgate Up or Down Revisited: in addition to tailgate up/down, also tested hardcover over pickup bed, tailgate removed, and tailgate mesh. Tailgate mesh was most efficient by 5%. busted " With my tonneau I lose 0.5MPH city. I use it primarily in the winter to prevent the bed from filling up with all that New England Snow... |

Concerning fuel mileage: I own a 2006 with 5.7ltr and mds. The only modifications are nitrogen filled tires (35PPI) and synthetic oil, With cruise set at 70 mph I can regularly get well over 21 miles per gallon (latest trip from Ringgold to Kingsland Ga was 21.9) City not much better than advertized (l6.1) I've also found that although Dodge recommends 89 octane for the HEMI, better milage can be obtained from 87 octane. Next trip I"ll set the cruise to 65 mph (my Dodge book says MDS works ONLY up to 65 mph! So far, nobody can verify that. Dodge also says that the 2009 model extends the speed limit for the same engine and MDS to 70 mph. Kind of makes one wonder, huh?

Replying to: ramrod2 (Jan 23, 2008 8:06 am) Just picked up a 2007 Dodge Ram 1500 5.7 Hemi 3 months ago. Have been getting about 15 MPG both City and Highway combined. Truck is less than 3 months old, not sure if it gets better once broken or not. I have a few quesitons for you experienced Ram owners: 1. Just wondering what Nitrogen filled tires do? 2. Where can i find a good "larger" aftermarket drivers seat or an OEM seat from a 2500/3500 model Ram? The one in my 1500 is too narrow to be comfortable, the seats in the larger Rams are bigger and more comfortable but Dodge says they can't order me a full seat!!! 3. On that gas mileage issue, the manual says to use 89 octane. That said, try to follow my logic and see if this makes sense: 87 octane gas is $3.00 per gallon & 89 octane is $3.10 per gallon so on a 25 gallon fill up, I would spend $2.50 more per fill up with 89 than with 87. If I get 1 more mile per gallon with 89 but am spending $2.50 more per fill up, thats the same as getting 1 less MPG with 87 therefore equaling the same dollar amount per fill up. Is this logic correct? If so, seems like a wash to me and I would be spending the same amount what ever gas I choose, 87 or 89 octane?? Am I thinking correctly here or did I smell too many gas fumes while filling up today? Is 87 bad for the HEMI engine or why is the reason Dodge recommends 89? Oh by the way, a fill up toda was $73.05 with 89 octane.  Thanks to all who respond. p.s. LOVE my 2007 RAM but has anyone see the new 2009 Ram on Youtube? This video and new 09 RAM rock!!! http://youtube.com/watch?v=beoKW6ya1gw&feature=related Ski in TX

2009 1500 is AWESOME! I'll be another year older by the time they come out; so you think 68 is a little old to be so enthused by a truck?

Replying to: stanoski (Jan 23, 2008 6:48 pm) While in the military, we used nitrogen to fill engine containers before air lifting to whereever. Speaking of loyalty, I've owned Dodge trucks since 1988 (they were twins to the Mitsubichi back then). I honestly can tell you that I can count the major poblems I've had on one hand! |
