How To Increase Diesel Engine Mileage?

  • Turn off the engine. Excessive warm-up times can deplete diesel fuel consumption, therefore avoid idling to save money.
  • When possible, use shore power. This is also known as truckstop electrification, because it allows drivers to plug in instead of idling, which helps to keep the vehicle cool while parked. Shower power is projected to save as much as $3,240 per year!
  • The engine should not be revved. Slowly transition to your next gear rather than as quickly as feasible. It’s a little less enjoyable, but it’s also a lot less expensive.
  • Find the sweet spot of your engine and ride it. Operating at the peak torque zone once you’ve reached your cruising speed provides you the most horsepower and diesel fuel mileage.
  • Make the most of your air conditioner by using it as little as possible. Running the air uses fuel, so if you can prevent it to save money, do so.
  • Be aware of approaching traffic signals. It is possible to save fuel by avoiding a complete halt. You’ll use less fuel if you can see the light is going to turn green and you can safely slow down without stopping.
  • Maintain a safe gap between you and the vehicle in front of you. The further you are from the vehicle in front of you, the less likely you are to have to stop. Stopping less also means avoiding excessive acceleration caused by braking.
  • Reduce your highway speed on a regular basis. While it may seem counterintuitive to get there faster, every mile per hour beyond 55 reduces your fuel economy by 0.1 miles per gallon.
  • Don’t slam on the brakes. To avoid fuel burn spikes, use smooth, constant gasoline acceleration.
  • Make use of your cruise control. You can avoid using the throttle to climb hills by utilizing cruise control to maintain a constant pace.
  • Use truckstops at the top of slopes if at all possible. Stopping at the top of a hill allows you to gradually return to the highway downhill, using less fuel. Alternatives can be found using the Multi Service Fuel Card truckstop locator.
  • When not utilizing cruise control, avoid accelerating excessively. Allow the truck’s momentum to carry it over the top of a hill to avoid slamming on the gas pedal too hard.

Why is my diesel getting bad mileage?

The flow of fuel into the engine might be severely hampered by a faulty fuel injector or a dirty/old fuel filter. One of the most prevalent causes of poor gas mileage is an issue with the fuel system. The more you use your air conditioner, the poorer your gas mileage will be.

How many miles can a diesel engine last?

What is the range of a diesel engine’s range of range of range of range of range of range of range of range of You do not need to overhaul your car if it has been running on gasoline for roughly 200,000 kilometers. A diesel engine, on the other hand, can run continuously for 1,000,000-1,500,000 miles before requiring major maintenance.

How do I get better mpg?

Above 50 miles per hour, gas mileage efficiency begins to decline. According to, drivers spend an additional 22 cents per gallon of petrol for every five miles per hour they surpass 50 mph. While each vehicle has its own ideal speed for fuel efficiency, speeding can impair fuel economy by 7 to 14 percent. Slower driving can save you 22 to 43 cents per gallon.

Should I buy a diesel with 200k miles?

Diesel trucks, on the whole, are sold with higher mileage than the average used vehicle. It’s not unusual to come across a used diesel truck for sale with more than 200,000 kilometers on it. Although diesel engines are generally more reliable than gasoline engines, excessive mileage remains an issue.

Which diesel engine lasts longest?

Because diesel pickup trucks have more durable engines that can sustain greater compression ratios, they often obtain better economy than gas trucks. Powerstroke, Cummins, and Duramax diesel vehicles often last well beyond 100,000 miles, even when used frequently for towing and hauling. As a result, diesel pickups with 200,000 or even 300,000 kilometers sometimes attract high resale values on the secondhand truck market. Drivers shopping for a used diesel pickup understand that a truck’s life isn’t over just because it has a lot of miles on it.

With modern trucks surviving longer than ever before, it’s not uncommon to come across gas trucks with 200,000-mile lifespans. Diesel trucks, on the other hand, can exceed that limit. Diesel pickup trucks may easily last 500,000 miles or more. It isn’t simply their engines that are more durable. Because diesel engines are heavier than gas engines, diesel vehicle hulls are designed and constructed to be more durable.

Not all high-mileage diesel trucks are created equal, much like other cars. For example, a diesel truck that has been used extensively for towing and transporting large loads for 100,000 miles may require serious repairs, whereas a diesel pickup that has been rarely used and has 200,000 miles on the clock may still have years of trouble-free life ahead of it. However, it’s also crucial to know that the life expectancy of a diesel vehicle is determined by a variety of other elements outside the odometer reading, such as:

For example, a 200,000-mile diesel pickup with only one or two owners and strong maintenance records is likely to be a better investment than a 100,000-mile vehicle with four owners and few records.

The general condition and appearance of the truck are also significant. A truck with a well-kept exterior and interior is likely to have had its mechanical components well-kept as well.

Duramax is a brand of diesel engine found in GMC and Chevy vehicles manufactured by General Motors. What constitutes excessive mileage for these engines is a matter of debate. Some owners consider 100,000 miles to be excessive mileage for Chevy diesel trucks, while others believe that anything less than 350,000 should be considered high mileage. A poorly maintained engine might swiftly deteriorate before reaching 100,000 miles, whereas a well-kept Duramax pickup truck should last 400,000 to 500,000 miles.

Cummins engines can be found in Dodge diesel trucks and Ram diesel trucks. Cummins diesel engines, like the Duramax, are designed to last a long time. On a Cummins diesel, 350,000 to 500,000 kilometers is normally considered high mileage. Of course, this is dependent on how well the engine is maintained.

Although maintaining the engine is crucial, some diesel pickup drivers believe it is even more important to keep the truck alive around the engine because the truck itself is less likely to last more than 500,000 miles, even if the diesel engine is well-maintained.

The Powerstroke engine, like the Duramax and Cummins engines, is found in Ford trucks and can last up to 500,000 kilometers. However, similar with the Duramax and Cummins engines, a Powerstroke engine with 350,000 to 500,000 miles on the clock is considered high mileage. The key to gaining the most miles is to keep the truck and engine in good shape. Ford vehicles are the most popular truck brand in the United States, and they’re regarded for their overall dependability.

Purchasing a diesel pickup truck with at least 250,000 kilometers could be a good deal. Diesel pickups are more expensive than their gasoline counterparts when new, so buying one used might save you a lot of money. When purchasing a used diesel truck, keep the following in mind:

Oil leaks are common in high-mileage engines, but they aren’t always cause for concern. It’s not uncommon to have small leaks around gaskets and seals. A little oil seepage around the front and rear main seals, for example, isn’t all that concerning and is even expected. Oil that is more densely coated around a seal or gasket, on the other hand, may raise suspicion. It depends on how much oil is smeared across the surface. To put it another way, while having no oil leak is definitely better, a tiny oil leak on a high-mileage diesel engine shouldn’t necessarily be a deal breaker.

When purchasing an older diesel truck with a mechanical injection system, it’s a good idea to start a diesel fuel additive routine. Long-term running without supplemental lubrication of one of these older diesel engines can result in early injection pump failure. A fuel additive, on the other hand, can improve modern diesel engines. Additives can help any diesel engine, whether it’s a high-mileage or not, get better gas mileage.

Distinct trucks and engines, like any other vehicle, have different challenges. Buying an engine model that appears to have the fewest difficulties may be irrelevant if the truck it’s in has issues. It’s also crucial to look into the individual truck’s troubles, in addition to the engine’s concerns. Maintenance records can be extremely useful in this situation.

For example, the water pump on a particular truck may fail every 100,000 miles or so. Even if a truck has 300,000 miles on it, if the water pump hasn’t been updated in 150,000 miles, you could be looking at expensive repairs.

On a high-mileage diesel truck, it’s never too late to switch to synthetic engine and gear oil. The following are some of the advantages of synthetic oil:

Heat, repetitive mechanical pressures, and chemical breakdown from fuel dilution are the major enemies of oil stability. All of these forces are more prone to higher-mileage engines. Synthetic oil can help a high-mileage diesel engine last longer and run more efficiently.

Synthetic oils, in the end, minimize friction better than traditional lubricants. Friction can increase as diesel parts wear out in high-mileage engines. More friction equals more heat, which accelerates the deterioration of oil and diesel truck parts.

To summarize, there is no single number that defines what constitutes high mileage for a diesel pickup truck; however, anything beyond 500,000 is commonly considered excessive mileage. However, remember that there are many more factors to consider when purchasing a used diesel pickup than mileage. A well-maintained, high-mileage Powerstroke, Cummins, or Duramax diesel pickup truck is almost always a better option than a poorly-maintained, heavily-used diesel pickup truck with lower mileage.

Is 200 000 km on a diesel too much?

Buying a used automobile can be a difficult undertaking, and you need think about a lot of things before signing the final piece of paper. However, checking a used car’s odometer for the number of kilometers it has driven in its lifespan is one of the simplest methods to obtain a quick feel on its value and how much life it has left.

There are several factors to consider in addition to the odometer reading. The mogo team strives to place its customers in their ideal vehicle at the best possible price and to give you with as much information as possible about your future used automobile purchase. To aid in this endeavor, we’ve compiled a list of items to look for when purchasing a secondhand vehicle.


As previously stated, miles are not the only metric for determining how much use a secondhand car will get. While it provides a decent, if speculative, picture of how much abuse the used automobile has taken over the years, the overall condition of the used car is far more important.

If there is any visible bodywork damage, or if a used automobile reaches the crucial 200,000-kilometer milestone, its value drops dramatically. The latter, on the other hand, isn’t always a hint that the secondhand car isn’t in good shape.

It’s usually a good idea to look over a used car’s service history, because if it hasn’t been consistent, it could be a red flag. Most cars with a reliable service history and roughly 200,000 kilometers on the clock should be a good buy if the price is right.

Of course, rare, older automobiles will have huge numbers on the odometer, but if they’ve been well cared for by a conscientious owner, those statistics won’t mean nearly as much.

The Numbers on the Dashboard Tell the Story

It pays to conduct some research before buying a used automobile with a questionable number of kilometers on the odometer. There is a wealth of information available on the internet about which makes and models have stood the test of time and which have faltered.

A automobile travels roughly 20,000 kilometers per year on average, therefore if the vehicle in issue has traveled more than this, there are certainly better options available. Rust is another deal breaker because it will only get worse with time, and parts for imported cars are generally rather expensive.

Most cars with more than 300,000 kilometers aren’t worth your attention unless you have prior experience working on cars and the price is appealing.

At mogo, we work hard to match our users with the exact automobile they’re looking for, and we’ve developed a system that ensures they always receive the greatest deal! Join the mogo team today and start looking!

How much fuel should I keep in my tank?

According to experts, you should always keep your petrol tank at least a quarter full. Obviously, keeping a little petrol in your tank will save you from getting into a perilous position when you’re low on gas and too far from a gas station to fill up, but there are other, less obvious reasons to do so. Driving on a nearly empty tank, or even one that’s coming close to the bottom, can damage your car in a variety of ways.

You won’t get very far driving on empty, but your car’s catalytic converter, which is part of the exhaust system, could be destroyed in the seconds before you stall out.

What’s the most fuel efficient speed?

In his budget on Wednesday, the chancellor promised a 1p per litre reduction in petrol duty and the cancellation of a 5p per litre fuel-escalator increase slated for next month. However, “hypermilers” claim that there are a slew of other methods for drivers to save money — and reduce emissions – simply by rethinking how they travel.

1. The Energy Saving Trust suggests changing gears before reaching 2,500 revolutions in a petrol automobile and 2,000 revs in a diesel car to maximize fuel economy. According to UK Road Safety, a Bristol-based teacher who offers “eco driving” courses, changing gears like this will help you save 15% on gas.

2. Make every effort to anticipate the road ahead of you. You may save money on gas and maintenance by driving as smoothly as possible, avoiding breaking or accelerating quickly.

3. Car heaters consume very little fuel since they recycle the heat from the engine. When it comes to air conditioning, though, the opposite is true. Opening the window slightly at speeds under 40 mph has no effect on fuel consumption, however air conditioning increases fuel consumption at all speeds.

4. Modern automobiles do not require “warming up” before driving. Similarly, revving or idling an engine before moving is ineffective and loses gasoline. As soon as you start the engine, drive away. Short journeys, on the other hand, can take up to 8 kilometers before the engine reaches maximum efficiency, implying that short journeys use significantly more gasoline per kilometer than long distance journeys.

5. When not in use, remove roof racks and boxes because they add a lot of drag.

6. Remove any additional weight from your vehicle, including fuel. Every 45kg of weight reduced from the vehicle saves 1% in fuel. It could be worth experimenting with not completely filling your tank and instead filling it more frequently.

7. According to the Energy Saving Trust, the most effective speed for attaining the best fuel efficiency in a car is 55-65 mph. Any quicker, however, and the fuel efficiency plummets. Driving at 85 mph, for example, consumes 40% more fuel than driving at 70 mph (and it’s also illegal).

8. Don’t travel in neutral in the mistaken notion that you’ll save gas. Instead, select the suitable gear for your speed. When in neutral, modern fuel-injected cars waste proportionately more fuel because they believe the car is idling.

9. Plan ahead of time to avoid traveling during the busiest times of the day. Stop-and-go driving is one of the most fuel-intensive modes of transportation. It is more fuel efficient to turn off the engine than to idle if you are stationary for more than 10 seconds.

10. Check your tyre pressure periodically because under-inflated tyres can increase fuel consumption by up to 3%.

11. Formula One drivers use the method of “drafting” or “slip-streaming” behind other vehicles to save fuel, yet it is extremely risky and frowned upon by road safety authorities. Switching off the motor while driving and coasting to a stop is likewise considered exceedingly dangerous.

12. Finally, a piece of advice for both fashionistas and drivers: “Don’t drive in huge shoes,” advises “They take away the throttle sensitivity that you require.”

Is it better to fill up at half a tank?

Respectfully, Tom and Ray: My coworkers and I are debating whether filling your gas tank halfway is more or less efficient than filling your gas tank completely. What is the most cost-effective method of filling a tank? Is it true that the weight of a full tank has an impact on mileage? Is it true that gas evaporates faster when the tank is half full? I need your assistance in deciding this debate and determining the most efficient method of filling a tank. Thank you very much! Ian’s words

Ray: Ian, I assume you’re concerned about the gasoline’s weight. You believe that because a full tank of gas weighs more, it affects your mileage. You’ll also have a lighter automobile and get more miles per gallon if you only fill it halfway.
