What Does DTE Mean In A Car?

I will be talking about what DTE mean in a car. There are certain lights, inscriptions, and warnings/features that car owners need to know. Before the invention of diesel vehicles with electronic engine management and fuel injection for petrol-powered engines, drivers relied on inaccurate spindle gauges in the gas tank in order to know the level of their gas. This, however, gives a vague understanding of fuel economy and many other experiences.

Many decades ago, many vehicles were not equipped with low-fuel warning lights. You see, the fuel gauge on your dashboard plays an essential role.

As technology evolves in the automotive industry, you will hardly see cars that won’t show your gas level in kilometers and miles. Most cars will display it alongside average gas mileage and the average speed to travel on. Some are designed with extreme simplicity, making them easier to spot than others.

The DTE is said to be of the utmost importance in vehicles by experts and many other drivers. Even as many drivers use it, many still don’t know what it means in a car. So, to bring it nearer to your understanding, it’s related to the fuel level consumed by your car.

Where does DTE come from?

During the 1960s and 80s, there were lots of sophisticated engine management systems that allows for accurate measurement of the fuel consumed, and in-tank fuel also. The need to avoid running low on diesel cars, as the overly pressurized pump system could get airlocks and need to be primed. While some cars that don’t have a mechanical solution to this have a squeeze-bulb under the bonnet which cranks the engine but risks the draining of the battery before the fuel gets to the injectors.

What Does DTE Mean In A Car?

Drivers have seen this on their dashboard but are stunned by what it means. I guess you have wondered also and that’s why you’re here. The DTE on a car means “Distance till Empty”. This lets you know the distance your car will cover before it will run out of fuel or charge.

With it, you can easily decide when to pull over at the filling station to have a fuel refill.

What About the Remaining Range of Electric Cars?

Electric cars, usually display range as a primary function. Some other cars don’t disclose this information and drivers don’t ignore it. Since electric cars don’t have external reserves, that means once your charge is consumed, you’re stuck. And to recover an electric car is all about moving to a charging location. You can find the nearest available charging point using Zap-map.

What About the Rumors of Reserve Capacity on Batteries?

Yes, electric cars have a reserve charge capacity to charge the battery should it starts running low. And leaving your battery to run at zero will drain the battery life thereby shortening its life span. But this reserve is locked up with software for a good purpose.

Like Tesla, it sold some 60kWh cars with a huge capacity than the specified 75kWh battery cap. While the electric car owners can pay to have the extra capacity unlocked, and in a national emergency, Tesla showed their readiness to permit the extra range for owners to evacuate any dangerous environment or natural disaster.

Is DTE Accurate?

Now you understand what DTE does in a car, how it functions, and where it is located, is DTE accurate? Some drivers don’t know whether the DTE on their car is correct or not. Some others say it is not extremely accurate. The answer to DTE accuracy depends on your vehicle and average gas mileage.

In the technological and automotive industry, we can’t guarantee any technology to be 100% accurate. There is usually a deviation that must be skipped by designers. And DTE is not an exception.

You should note that this “Distance till Empty” depends on several factors to make its decision. Such factors include altitude, time of day, your driving style, wind resistance, speed, and others. Therefore, the DTE display is not always accurate.

But the discrepancies between what it reports and what the tank holds may not be high. Let’s look at this scenario, assuming you have 6 miles left to reach your destination, and the DTE says you have a 6-mile-fuel left in the tank. So, it’s time for a refill. However, the time distance could cause it to degrade. Therefore, it’s not as accurate as often.

Therefore, it’s important to check the accuracy of the indicator regularly while you drive, otherwise, you have your car run out of fuel or charge.

To ensure the accuracy of your DTE, you need to get rid of the air bubbles in the gas tank/pipes (by shaking your car when fueling). By doing so, you’ll get a more accurate reading.

How to Calculate DTE?

As stated earlier, more factors make up the report of the DTE.

To calculate it might not be straightforward but it is worth knowing that the lower the number, the lesser your fuel is getting. But if you have a full tank, there’s no need to worry about it as you can go about 200 miles. Well, this figure depends on your vehicle type and model.

Additionally, the octane level of fuel influence the DTE calculation. The figure will be increased as the range goes higher while the lower won’t have any effect.

If you consume the premium fuel, it will get better mileage. While the low-range fuel can impact negatively the engine.

Therefore, choosing a fuel type for your car is of good importance to its maintenance and DTE accuracy.

DTE Calculation

With MPG and the level of fuel left in the tank, the formula is attainable. To get your DTE, divide the fuel left by the MPG.

Although, if you’re driving and doing this, you will get the wrong figure as the DTE changes over time.

MPG Meaning

MPG simply means “miles per gallon”. Another to understand this is that it indicates the distance your car could cover with every gallon. The higher the number indicated, the better your car’s fuel economy is.

Automobile manufacturers are known for providing their manufactured cars with three different figures. All are linked to the fuel consumption of the vehicle.

  • Urban: A city driving
  • Extra-urban: A highway driving
  • Combined: A combination of highway and city driving

You need to know one of these figures as they’re not replicable by any person. Because they’re inbuilt into the system by the manufacturers.

Can You Reset DTE Calculator?

When you notice the DTE calculation is everywhere, you may decide to wipe the tracked data.

With the reset, the calculator can start afresh from zero. But you have a few options available to certify the fuel economy of your vehicle.

Haven knows that to reset the DTE, you can disconnect the battery and it will reset.

In normal circumstances, we won’t encourage you to reset it because it can cause the DTE to be less accurate after reset. Alternatively, you can allow the technology to reset itself.


Q: Is it bad to run a car on low fuel?

A good rule of thumb is always to run your car with enough fuel. It is recommended not to allow your energy to drop to ¼ in the gas tank. Here are the reasons for the recommendation.

It can keep you stranded: Internal combustion engines, unlike electric cars,  can not run without gas. If you run out of gas, the vehicle will stop whenever and wherever it happens. If this occurs, you have the option of walking down to the nearest gas station or calling for help.

Aside from the inconvenience to the drivers and passengers, it is a significant safety concern. If your gas finishes while commuting on your daily activities, pull out of the road to a safe spot before thinking of where to get help or gas.

It can cause damage to your vehicle: while battling the inconveniences and safety issues, driving with low fuel in a car will cause premature failure of some critical fuel injection components like the fuel pump. These components may not fail for running out of gas once or twice, but it will shorten their lifespan.

Q: How much reserve fuel does a car have?

The amount of reserve fuel a car has depends on the car’s make and model. In some vehicles, the reserve gas they can hold is about 1 gallon (3.8 liters), while others have 10 to 15 percent of the total amount of gas the tank can contain.

Final Thoughts

We have been able to explain what DTE means in a car and its importance to both fuel-run cars and electric cars.  Most manufacturers refer to DTE as “distance till empty”, “distance to empty”, or “due to empty”. No matter the classification they choose, it all represents the same thing. It helps you know the distance your car can cover with the available fuel.
