Which Diesel Truck Has The Best Fuel Economy?

In our ranks of the most fuel-efficient trucks, Ram is a close second to Chevy. In all aspects of EPA testing, the diesel-powered 2020 RAM 1500 trails the similar Silverado by a single digit. The Ram gets 22 mpg in the city, 32 mpg on the highway, and 26 mpg on the combined highway.

Which diesel truck gets the most miles per gallon?

For the most fuel-efficient pickup trucks from major automobile manufacturers, the maximum miles per gallon (MPG) range is about 20-27 MPG.

Which of the two 2500 diesel trucks gets the best fuel economy?

The Ram 2500’s gas V-8 engine is the greatest choice for a 2500 series truck with the best fuel economy.

This engine delivers excellent performance while saving you money at the gas station. This truck gets 16 mpg in the city and 22 mpg on the interstate, making it one of the most fuel-efficient pickups on the market.

With the current redesign of all Ram trucks, this truck not only has one of the best interiors, but also one of the coolest exteriors of any pickup.

It’s easy to see why so many people consider the Ram truck series to be one of the greatest on the market today.

What is the best MPG for a 1 ton diesel truck?

For a diesel truck, the new Chevy Silverado has the best fuel efficiency. It gets 33 miles per gallon on the interstate, 22 miles per gallon in the city, and 27 miles per gallon overall. The GMC Sierra 1500 is essentially the same truck, but its fuel economy is worse, at 30 miles per gallon on the highway, 23 miles per gallon in the city, and 26 miles per gallon combined. Both vehicles’ 4WD variants earn slightly lower MPG than their 2WD counterparts. The Duramax turbodiesel engine in the Silverado is 3.0 liters.

Is a Duramax engine superior to a Cummins engine?

Cummins vs. Ford The Cummins engine is currently a 6.7-liter inline-six, whilst the Duramax is a 6.6-liter V8. The Duramax is the most powerful engine in terms of horsepower, but the Cummins is the most powerful in terms of torque, with values up to 1,000 ft-lbs depending on the truck.

Is it worthwhile to invest in a diesel truck?

Diesel trucks can not only transport greater loads, but they can also do so more effectively, conserving fuel. As a result, they’re ideal for both professional and leisure use. They are capable of doing difficult tasks on the job and can pull sport vehicles, trailers, and campers without reluctance.

What is the mpg rating of a 6.6 Duramax?

The 2500 level of the 2021 Sierra HD series contains a diesel engine that produces 445 horsepower and 910 pound-feet of torque. On the freeway, this Duramax 6.6-liter V-8 scores 17 to 19 mpg.

Issues With the Fuel Lift Pump

The fuel system of Duramax diesel engines is direct injection. The fuel injection pump is one of the most significant components of this fuel system. Most Duramax engines come with a CP3 fuel injection pump, which is reliable but not extremely strong.

Because this fuel system lacks a lift pump, the injection pump must work extremely hard to both suction and pressurize the gasoline. When the engine accelerates, the lack of a fuel lift pump usually results in a loss of fuel rail pressure.

How To Fix This Lift Pump Problem

Adding an aftermarket lift pump is probably the best way to address this common Duramax issue. You may extend the life of your Duramax engine by installing a lift pump. A new lift pump boosts engine performance while lowering pollutants.

Water Pump Problems Are Common

Water pumps with plastic impellers are standard on newer Duramax engines. These impellers are flimsy and prone to breaking. Duramax engines’ water pumps are similarly prone to leaking. Engine overheating can occur as a result of these leaks. Water pump leaks can potentially impair system pressure, resulting in insufficient coolant supply.

Replacing a Duramax Water Pump

When you have a broken water pump, you should replace it straight soon. It’s a good idea to look for a water pump replacement with an iron impeller. These impeller replacements tend to last longer and function better. If your Duramax engine has a lot of miles on it, the thermostat and water pump housing may need to be replaced. This will help you avoid future problems with your cooling system.

Duramax Engines Are Notorious For Fuel Injector Problems

The original fuel injectors that these engines come with are maybe the most prevalent gripe you will hear from Duramax diesel owners. GM’s staff even confessed that its injectors were badly built and that they had been modified in recent years. One of the most serious issues with these injectors is their proclivity for cracking.

Fault ball seats are also present in these injectors. These injectors leak over time due to malfunctioning ball seats. Injector failure can result in power loss, harsh idling, and excessive smoke.

Remedying Your Injector Issues

The only method to solve this problem is to replace faulty injectors. Because these injectors are hidden beneath a variety of other engine components, it’s a good idea to have them replaced by professionals.

How many miles per gallon does a 6.7 Cummins get?

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.

On a Duramax, how can you achieve 30 mpg?

Is it feasible to improve your Duramax truck’s fuel efficiency by using aftermarket Duramax parts? Because new diesel trucks are becoming more expensive, it’s understandable that owners would want to keep their older trucks on the road for as long as possible while still obtaining good gas mileage. It may be able to improve the performance and fuel economy of certain of your diesel truck parts.
