Tips to save you money for the long haul.

For truck drivers, fuel expenses can be one of the most significant costs to their business. Improving fuel efficiency is, therefore, critical to saving money and increasing profits. Even a small increase of just one mile per gallon (MPG) can lead to substantial savings of over $10,000 per year. Fortunately, there are many ways to improve fuel efficiency, and truck drivers can make a big impact by making a few simple adjustments to their driving habits and maintaining their vehicles. In this article, we will discuss all ways for truck drivers to improve their fuel efficiency and save money.

Top 15 Ways for Truck Drivers to Improve Fuel Efficiency

1. Watch Your Speed

Your speed is one of the biggest factors affecting fuel economy. For every mile per hour over 60 mph, your fuel economy reduces by one-tenth of a mile per gallon. By reducing your speed, you can save fuel and improve your mileage. For example, a truck traveling at 65 mph is 27% more fuel-efficient than one traveling at 75 mph.

2. Accelerate Gradually

Fast, hard acceleration wastes fuel and puts a strain on your engine. Try to anticipate acceleration points, so you can use the appropriate amount of acceleration for the situation.

3. Be Moderate with Braking

Frequent braking and accelerating can decrease fuel efficiency. Braking wastes energy and reduces fuel economy. Two of the best ways to reduce braking are to anticipate changes in traffic and follow at an extended distance.

4. Manage Cruise RPM

It's essential to find the "sweet spot" that maximizes your engine's efficiency. Typically, the optimal RPM range for fuel economy is between 1250-1350 RPM.

5. Use Cruise Control

Cruise control can help you maintain a consistent speed, avoiding unnecessary acceleration and deceleration, and saving up to 6% on fuel consumption. Cruise control helps maintain a consistent speed and avoids unnecessary accelerations and decelerations. Adaptive cruise is even better; use it if your vehicle is equipped.

6. Use Your Momentum

Use the momentum gained while driving downhill to climb the next hill, reducing the amount of fuel needed.

7. Minimize Idling

Idling consumes fuel, so avoid doing it when not necessary. One hour of idling can burn up to a gallon of fuel. Idling wastes fuel and reduces your fuel economy. A 10% annual reduction in idling can save you about 1% in fuel economy, translating to about $300 to $500 annually at $3/gallon fuel prices and 100,000 miles per year. Use a windshield curtain or solar reflector to keep heat loading out of the cab.

8. Take the shortest route

Take the shortest and quickest reasonable route with the least stops to your destination. Plan to avoid rush hour traffic.

9. Minimize Shifting

If you're not using an automated transmission, minimize the number of shifts you make. Every time you shift, the engine RPMs increase, and you burn fuel. Try to shift to the next highest gear while still at a low RPM. By minimizing the number of shifts, you can improve your fuel efficiency and save money on fuel costs

10. Stay in Higher Gear

Driving in the highest gear possible can maximize fuel efficiency, reducing fuel consumption by up to 45%.

11. Keep Load Height Low

A lower center of gravity can decrease the effort needed to get the truck moving. Keep the load as low and level as possible.

12. Invest in Aerodynamics/Check Condition of Aerodynamic Devices

Adding tractor-side fairings, deep-angled bumpers, and trailer skirts can improve aerodynamics, increasing fuel efficiency. Ensure all aerodynamic devices are in good condition, with no dents, rips, tears, or dangling parts. Minimize the tractor-to-trailer gap to improve fuel efficiency.

13. Check Battery Cables

Corroded battery cables can make the alternator work harder, decreasing fuel efficiency.

14. Inspect the Fan

A faulty engine fan can decrease fuel efficiency by consuming more horsepower.

15. Check Tire Inflation Pressure

Underinflated tires result in decreased fuel efficiency and increased tire wear. Ensure your tires are properly inflated, as a 0.5-1.0% increase in fuel consumption is seen in vehicles running with tires underinflated by 10 psi. Every 1 PSI drop in pressure can result in a 0.3% reduction in fuel mileage.
