The 6.6-liter Duramax turbodiesel engine in the diesel Chevy Silverado 2500 HD (which is nearly identical to the GMC Sierra 2500 HD) is mated with a six-speed Allison automatic transmission. Consumer Reports evaluated a four-door, four-wheel-drive trim. The Silverado 2500 HD gets 14 miles per gallon on average.
The F-250 is equipped with a 6.7-liter Powerstroke turbodiesel V8 engine that produces enough horsepower to outperform the Silverado 2500 and Ram 2500. It also has an aluminum-alloy body, making it lighter than the normal heavy-duty vehicle. Consumer Reports found that the F-250 four-door Lariat variant gets 15 MPG overall.
Nissan Titan XD
The Titan is designed to fall somewhere between light-duty half-ton vehicles and heavy-duty three-quarter-ton trucks. The Titan’s Cummins diesel engine is a smaller 5.0-liter V8 turbo diesel. Despite the lighter engine, the Titan’s four-door SV version only gets 15 MPG overall.
The Ram 2500 is equipped with a 6.7-liter Cummins inline-six turbodiesel engine that produces a lot of torque. The engine is mated to a six-speed automatic transmission. The Ram 2500 gets 14 MPG overall when tested in a four-door Laramie model.
How many MPG does a 5.9 Cummins get?
My youngest brother got a new 3500 Ram daully with a 5.9L Cummins engine in 2004 and showed it to my father. My father then went out and got a new 2004 2500 Ram with a 5.9L Cummins engine, which he showed me. Unfortunately, I was just getting back on my feet after being laid off for three years, so I returned to work and saved everything I could until late 2006, when I purchased my first new Dodge 2500 Ram with the 5.9L Cummins engine. Since 2006, I’ve bought my wife two trucks: a new 2008 Dodge 2500 Ram with a 6.7L Cummins engine and a 1999 Dodge 2500 with a 6.7L Cummins engine (which has a 6 inch lift, racing trans, Smarty Tuner, modified straight pipe, and custom rims). I still have the 2006, but I sold the 2008 because it was equipped with a 6.7L Cummins engine. In 2012, I came upon a 2001 Dodge Ram 2500 with 39,900 original miles and a 5.9L Cummins engine. In 2010, I purchased a 2002 Dodge 2500 Ram with a 5.9L Cummins engine for each of my two college-aged boys. We upgraded one truck with the same racing transmission overhaul as my wife’s ’99, along with a Smarty Tuner, to increase RWHP to 410 and torque to 700 foot-lbs. Needless to say, the 5.9L Cummins has won us over. The vehicles have excellent fuel efficiency after our modifications, air intake upgrades, and exhaust straight pipe swaps. We have five Dodge 4×4 pickups with the 5.9L Cummins engine, and we love them all. We get 29 miles per gallon on the freeway and 24 miles per gallon in town with the five trucks we own. The Cummins 5.9L has the fuel economy, speed, and pulling power to get the job done. We only drive Cummins 5.9L engines, and we couldn’t be happier with the results!
Here are some of my suggestions for keeping our trucks in top shape!
In the stock air intake, install a K&N filter.
Change the oil in the box on a regular basis. Maintain spec levels for all fluids.
Remove the “silencer ring” from the “silencer ring” in the “silencer ring” in
For a better sound and a little increase in MPG (around +1 MPG), add a turbocharger.
Maintain maximum tire pressures per tire.

For the finest MPG performance, choose the best.
Using a straight pipe, connect the turbo’s exhaust to the rest of the system.

Using a 4 inch diameter pipe, return from the catalytic converter.
Install a five-inch exhaust tip (stainless steel if possible).
you enjoy adorning the pipe).
Use a MADS Smarty Down Loader, but not a MADS Smarty Down Loader.
Stock trans is suggested. Take note of this:
Only if the trans has been upgraded/rebuilt with more ft.-lbs. is it smart:
capacity of over 700 ft-lbs, as well as a heavy-duty Billet Shaft, etc., otherwise you risk damaging the machine.
Finally, and most crucially, apply a gasoline additive to your vehicle. Howe’s anti-gel and Lucas Oil Fuel are the products we utilize.
“Injector Cleaner – Upper Cylinder Engine Lubricant” as an additive
Every tank should be filled with 2.0 oz/10 gallons of fuel.
To assist, recommend using a (1.0 oz. graduated) 10 oz. infant bottle.
Pour into the tank after measuring.
Have fun on the road!
Which diesel gets best MPG?
The 2.0L I-4 180hp intercooled turbo engine, 8-speed automatic transmission with overdrive, 4-wheel anti-lock brakes (ABS), integrated navigation system, side seat mounted airbags, curtain 1st and 2nd row overhead airbags, airbag occupancy sensor, automatic air conditioning, 19″ aluminum wheels, cruise control, ABS, and driveline traction control are all standard features on the Land Rover Range Rover Velar D180 S.
What’s the MPG on a 6.7 Cummins?
The Cummins Turbo Diesel Inline-6 and 6.4-liter HEMI V8 engines in the 2022 RAM 2500 deliver up to 410 horsepower and 429 pound-feet of torque in 4×4 form. In four-wheel drive mode, the engine is rated to get up to 12 city/18 highway/15 combined MPG. When properly outfitted, the RAM 2500 2022 can tow up to 20,000 pounds.
Is the Cummins 6.7 a good engine?
The 6.7L Cummins engine in the Dodge Ram ISB is a powerful diesel engine. It was the first light-duty vehicle to reach 1,000 pound-feet of torque, with the 6.7 Power Stroke following close behind. There’s little doubt that the 6.7 diesel engine has enough power and torque to satisfy practically any driver. However, no engine is flawless, and the Cummins 6.7 is no exception.
It’s largely emissions equipment that reduces the engine’s power. On the 6.7 Cummins, as well as many other modern diesels, EGR and DPF issues are frequent. The 6.7L engine’s high torque can cause problems with the head gaskets failing. Turbo difficulties are conceivable with increasing mileage because they are subjected to a lot of abuse. Fuel dilution is another concern that might arise, however doing an oil study on a regular basis can assist to limit the hazards of dilution.
Overall, Dodge and Ram trucks with the 6.7 Cummins engine are dependable. Sure, it lacks the legendary status of previous diesels such as the 7.3 PS or 5.9 Cummins. Unfortunately, modern-day emissions parts work against reliability in a variety of ways. However, if the 6.7 Cummins is adequately maintained, it should easily exceed 250,000 miles.
Is 24v better than 12v Cummins?
For bone stock performance, the newer ISB 5.9 24v Cummins wins. Beginning in 1998, ISB engines produce 235 horsepower and 460 pound-feet of torque. Only a little upgrade over the previous Cummins 6BT 12 valve. The Ram ISB 5.9 diesel, on the other hand, acquired common rail fuel injection in 2003. This helped improve power to 305 horsepower and 555 pound-feet of torque. A year later, this was boosted to 325 horsepower and 600 pound-feet of torque.
Of course, years of scientific and engineering advancements have enabled newer engines to perform better. When comparing the performance of the 12v and 24v Cummins engines, the later 24v engines are unquestionably superior. That isn’t to imply that the 12v Cummins isn’t capable.
v vs 24v Tuning & Aftermarket Potential
The 24v engine is still the preferable alternative for individuals wishing to keep things simple with a tune and modest bolt-ons. It’s a lot easier to tune because the electronics support “chip” tunes. The VP44 injection pump, on the other hand, is a big stumbling block for anyone wishing to push the engines to their limits.
The 12v 5.9 Cummins wins when it comes to significant power and performance. When compared to 24v engines, these engines are renowned to keep up better at high power levels. On the 6BT, the P7100 injection pumps are easy to modify and support the extra power.
In conclusion, the 24v is the best street engine for individuals who want to keep things simple or modest. The older 12v Cummins engine is likely the superior choice if you’re searching for high power and performance. Getting any engine or transmission to 600+whp isn’t cheap, though.
How can I get better gas mileage in my Dodge Cummins diesel?
Drive your Cummins-powered truck as efficiently as possible. Remember that diesel engines are most efficient and provide the maximum torque when they are running at a low RPM. As a result, when driving on the highway, utilize cruise control to keep your truck’s speed below 65 mph. This will maintain your tachometer on the low end of the scale, allowing you to get more miles out of your car.
Is a diesel truck worth it?
The high upfront cost of the powerplant is one downside of diesel trucks. However, you can rest comfortable that at least a portion of your investment will be recouped when you sell the truck. “Heavy-duty diesels have a higher residual value, according to Barta. “Customers appreciate the extra power and towing capabilities, and they are ready to pay for it.” Diesel trucks are routinely worth more than gas trucks on the used market, according to Kelley Blue Book values.
A 2016 Ram 3500 diesel with the same trim level and options has a value that is 17 percent greater than a gas with the same trim level and options in May 2021, according to data. The diesel version of the 2018 Ford F-250 costs 10% more than comparable models. Light-duty trucks are less expensive. The cost of a 2016 Chevy Colorado diesel is only 5% more than the cost of gasoline. The prices for a 2018 Ram 1500 diesel are merely 2% more. So, depending on the model, a diesel investment may be worthwhile when it comes time to sell.
Do diesel pickup trucks get better gas mileage?
Diesel-powered pickup trucks are more fuel-efficient than their gasoline-powered equivalents, according to Car and Driver research. According to Car & Driver, this is because diesel fuel has more energy per gallon than gasoline. Diesel trucks also produce more torque, which, according to Car & Driver, results in improved fuel economy and acceleration.
