Every truck driver is always looking for a way to cut costs, especially fleet truck managers. Since trucks are associated with massive works and terrains, they consume a lot of fuel. However, you can minimize such costs through some simple practices to do with maintenance and modifications that will make your truck more economical.

Frequently do oil changes.

Engine oil is what keeps your engine in good condition and thus minimize your overall truck's cost. It lubricates the engine and reduces friction in its various parts, therefore prolonging its shelf life. Regularly check your oil engine so that when depleted, you refill early enough. That way, you will minimize wear and tear caused by friction, making your truck more economical.

Check on the air filter.

The truck’s air filters are always prone to dirt and contamination. A dirty air filter leads to more fuel usage and can even cause more problems in older trucks. If your vehicle is more than 11years old on the road, pay more attention to the air filter. Always inspect the air filter and replace it if it is dirty. An air filter replacement is a simple hand job that you can accomplish with around 15minutes or less with simple tools. As simple as it sounds, it will improve your truck's economy by far.

Ensure your diesel truck doesn’t run out of DEF

Diesel exhaust fluid is useful in diesel trucks to convert poisonous nitrogen oxides into harmless water and gas, reducing air pollution. Although you won't have to refill your DEF tank every time you fuel your truck, keeping it at the right levels will reduce fuel consumption. PEAK C & I improves fuel economy by allowing the engine to run a smooth air to fuel ratio hence using less fuel. With DEF taking care of the pollutants, most truck manufacturers and drivers have discovered better fuel mileage.

Keep the tires in good condition.

When you keep your tires with enough air pressure, it reduces the levels of drag the engine has to overcome. Not only inflating them but also keeping them well aligned and in good condition. You can use a set of all-weather tires or invest in a set for highway driving and another for winter or snow driving. Tires can reduce rolling resistance by 10% and consequently improve fuel mileage.

Use the proper tires, and check them daily if you can to catch air leaks early enough. While investing in the right tires might be expensive, it pays in the long run since it improves your fuel economy. 

Keep an eye on your truck's spark plugs.

Spark plugs show what is going on in the engine's internal combustion, so you should monitor it. Replace spark plugs at every 60,000miles if you use platinum or iridium plugs and 7000miles or annually if it's copper plugs. Even though they may not need a replacement, monitoring them helps a lot. At least inspect them once per year.

For instance, a stained spark pug means that the motor is running lean or rich. If it is lean, it means you don't have enough fuel. If it is rich, it indicates too much fuel consumption.

The bottom line

To conclude, the way you drive also affects your fuel consumption. So, drive moderately, do not let your truck engine idle since that burns up more fuel than switching it off and restarting it, and always park under shade to minimize fuel evaporation.
