Truck Maintenance Myths That Are False

Every truck owner will be keen on listening for advice about the best practices for keeping their trucks healthy. This advice ranges from fuel economy, engine, and overall vehicle maintenance. The myths you will hear are about how to improve your truck’s economy. Most of what you will hear as a truck owner will sound very practical. Here, you will be able to know some truck maintenance myths which are false.

Fueling in the Morning Saves Money on Fuel

We all know that fuel expands with an increase in temperature, and when you pour warm fuel into your gas tank, there is a high possibility of it evaporating, and less fuel will get into your tank. Theoretically, when you pump fuel into your tank in the morning, the fuel will be cooler and more will get to the tank at a lesser cost. 

On the contrary, fuel is stored underground under controlled temperatures. The environmental temperature does not affect the fuel temperature underground because they are insulated from harsh temperatures.

Roll Down Windows instead of Using Air Conditioner to Boost Fuel Economy on a Hot Temperature. 

Rolling down windows to allow cool air in the truck and using AC makes no significant difference in fuel consumption. Your truck will indeed consume more fuel when you switch on the AC. But when you roll down your windows, the air resistance will increase. The increased air resistance makes your truck burn more fuel to compensate for the disrupted aerodynamics. 

The effect of AC and rolled-down windows on fuel economy is minimal, and none of the practices reduces fuel consumption.

Flushing the Transmission Fluid After Every 50,000 Miles

Changing your transmission fluid after covering 50,000 miles is recommended, but modern trucks are engineered to last with transmission fluid oil after 100,000 miles. The life span of transmission fluid varies among vehicles, so you must check the recommended mileage from your manufacturer’s guide.

The Battery Starts to Charge After Jumpstarting When You Drive Shortly

In the real sense, a battery that has been jumpstarted takes a couple of hours to charge fully. If you have just jumpstarted your engine in cold weather, other truck accessories such as the heated seats, radio and lights take more power from the alternator leaving little power to charge the battery.

It would be best to drive for several hours for your car to charge fully. Sometimes, your battery might remain dead even after driving for a long time. 

Replacing All the Four Tires at the Same Time

You can replace each tire so long as they are of the same brand, size, and model. However, you must keep rotating them to improve and maximize their life span.

You don’t have to buy new tires whenever you get a puncture. Your mechanic will mend it if the puncture has interfered with the side wall. The patch will restore your tire’s airtightness.


As long as you own a truck, you will come across various myths about maximizing your truck’s performance. These are just myths. No facts are tied to them.
