I know that going from fillup to fillup across states isn't the most accurate method of measuring, but it's what I have to work with. I am no mechanic and a lot of what I read is greek to me so I'm hoping to get some advice from those that I believe are in the know. I'm running Mopar 15W-40 year round with use of a winter block heater to avoid startup damage. So this tells us something about the sensitivity of gearing. I fill up at the beginning of every trip, and log fuel purchases and mileage until the next time I can fill up at my favorite station.
The basic paradigm with a turbocharged diesel is that the more fuel flowing into the engine, the more horsepower and torque. As for single drive versus dually, any mileage difference should reflect vehicle weight savings, and little more. Heavy-duty pickups are a special breed of hauler. I work for the City and we've got tons of strokers running around. Kidding aside, this could pay big in fuel savings and also offer some incredible torque and pulling options as a split-shifter. It's among my favorite subjects, as you might have guessed. If you're curious about Ram truck speedometer calibration, see my video coverage at the magazine:.
I had new DynaTrac Ball Joints installed which, after a little sticky break in period, are tracking very well. With stock tires I beleive 3. For trucks with the 5. As proof in my case, I got the best mileage to date with a stone stock truck. The overall effect was an increase in drag coefficient. You're making fantastic horsepower, I'm sure! Most of this difference is tuning or tune programming for these common rail, electronically fuel injected engines.
What's interesting is the potential horsepower and torque latent in these Cummins engines. If I want to save on fuel I'll by a smart car. Only 12,000 or so miles have been trailer pulling, and I am considerate of the powertrain when towing. In my experience, that rpm would drop the mileage to the 17-18 mph range unloaded. So I'm thinking all my upgrades don't help me much for fuel efficiency other that it is a fun truck to drive with all the power it has. Am I crazy or is there science and math behind it? That is why I always put my name in my sig on forums.
Once the axle gearing is correct, the other factors that drop fuel mileage on your '06 Ram 3500 Cummins would be 1 the increased vehicle height kiss off aerodynamics of any kind! My choice of running 75W-140 Mopar gear lube for severe duty use may, in fact, create a loss in fuel efficiencyāespecially in the winter. Perhaps a chip could improve this further, although my belief is that driving technique holds far more sway over fuel efficiency than any other factor. I like fan clutches that have thermal couplers. A denser charge means improved combustion and, at least theoretically, better fuel efficiency if you can keep your foot out of the more responsive throttle! If we boost horsepower or torque and stay in the throttle to realize these gains under severe loads, the result is engine-killing heat and huge losses in fuel efficiency. I can calibrate for tire diameter with the Hypertech Max Energy programmer see details at the magazine. Interestingly, that trip included mountain passes, so the mileage was apparently influenced more by engine rpm than load.
Moses I drive a 2008 Dodge Ram 3500 Cummins. It's a lot to take in at once, so I'll digest a little at a time and I'm sure I'll have questions. See the interesting torque gains described at the Gear Vendor's website. I knew that when I added accessories, a lift and oversized tires, plus auxiliary fuel capacity, that the mileage would suffer. By the way, it's very nice of me to help spend your income on items like a Gear Vendors overdrive! Join our free forums and get the full benefits of membership! Watch your rear view mirrors for flashing red and blue lights. I asked this question before but I never really got a good answer. The truck runs fantastically, but the power is now further up the rpm scale with peak torque around 2100 rpm.
This engine was not designed for grocery getting or local commutes. Pyrometer and boost gauge will be installed prior to purchasing a tuner. What about dropping the final drive to 3. Even slower, like 55 mph 1700 rpm , should deliver better mileage yet. I am a fan of science and am amazed how it can effect my wallet on daily driving. Here is our truck, it's still on the dealership web-site right now. Me on the other hand, I could have bought another truck just with the money in parts.
Those pumps are an eyesore to me and I need another solution that will allow me to pump fuel while driving. These full-size leviathans are built to tote and transfer big-time payloads and pull trailers weighing in excess of 10,000 pounds. If your turbo is sealed up good and no boost leaks in the system, you should be running like a champ. For the oversized tires, 4. Let me know what ya think. Please share that information and indicate whether you have a manual or automatic transmission.
Better yet, and consistent with your plans, they had an '02 that ran to 600K miles before selling it, and the father insisted that the truck is still out there doing fine. Sounds like a pain to keep up with, having to keep that close an eye on the fuel gauge for so long but whatever works for him. Additional weight drops mileage in any case. I don't think this could lead to an intake runner but I don't have a good cutaway to confirm what touches what in the head. Where do real names show up in the profiles? There was only minor service and programming updates done up unitl now so I know there was no bad past history. Have you gone this route yet or maybe anybody that is reading this? The dealer 65 miles away has worked on it numerous times, but it still clogs up. A Max Energy program for your engine could make a difference in two ways: 1 an overall increase in performance and 2 bumping the peak torque rpm up, which would make your 2000 rpm cruise speed more viable for fuel efficiency.
