When you’re out on the road, it’s easy for myths and misinformation to spread faster than a rig on an open highway. From “fuel-saving hacks” that do more harm than good to maintenance misconceptions that could cost you thousands, there are plenty of trucking myths that need busting. Today, we’re setting the record straight on some of the most common trucking tall tales.
Myth #1: Letting Your Truck Idle Saves Fuel
Busted! Letting your engine idle for long periods actually burns unnecessary fuel and increases wear on your engine. Modern engines are designed to handle frequent starts and stops, and excessive idling can lead to carbon buildup, wasted fuel, and increased maintenance costs. Instead, use auxiliary power units (APUs) or simply turn off your engine when you’re parked.
Myth #2: Premium Diesel Always Improves Performance
Busted! While premium diesel contains additives that can improve engine cleanliness and lubrication, it doesn’t always translate to better fuel economy or performance. Most modern engines are designed to run efficiently on standard diesel. Instead of splurging on premium fuel, focus on high-quality, reputable fuel stations and proper maintenance to keep your truck running smoothly.
Myth #3: You Should Always Warm Up Your Truck for at Least 15 Minutes in Cold Weather
Busted! While it’s true that diesel engines need a little extra time to warm up in freezing temperatures, excessive idling isn’t the answer. In most cases, 3–5 minutes is plenty before hitting the road. The best way to warm up your engine is by driving at moderate speeds, allowing all components to reach optimal temperature naturally.
Myth #4: The Faster You Drive, the Quicker You’ll Get There (and Save Time & Money)
Busted! Speeding burns more fuel than you think. In fact, for every 5 mph over 60 mph, fuel efficiency drops significantly. Plus, higher speeds increase the risk of accidents and costly repairs. The best way to balance fuel efficiency and timely deliveries? Stick to a steady, controlled speed and use cruise control when possible.
Myth #5: Oil Changes Aren’t That Important—Just Top Off Your Oil When Needed
Busted! Oil changes are critical to extending the life of your engine. Simply topping off your oil instead of changing it can lead to sludge buildup, increased friction, and engine wear. Follow manufacturer recommendations for oil changes to prevent costly breakdowns.
Conclusion
When it comes to trucking, believing in myths can cost you money, time, and even safety. Stick to facts, follow regular maintenance schedules, and always question the “too good to be true” tricks that circulate on the road.
