Why Diesel Engines for Off-Road?

All of the vehicles on this list are available in both a gasoline and diesel option, so why should you opt for a diesel engine for an off-road truck? Diesel engines offer much better low-end torque, which is a huge advantage during off-roading.

Diesel engines are much more common in other countries around the world than in the United States, and for good reason. Diesels are more efficient than gasoline engines, and with correct maintenance, they can last a lot longer.

There are also some disadvantages to diesel trucks for off-roading. Here are a few downsides to consider:

  • Diesel engines are significantly heavier than gas engines.
  • Maintaining a diesel truck is typically more expensive.
  • Diesel fuel typically costs more per gallon, though improved fuel-efficiency can offset this difference.
  • Repairs are more expensive for diesels.

Off-Road Fuel for Diesel Engines

If you’re searching the internet for off-road diesel vehicles, you may have come across sites talking about off-road diesel fuel. The terminology may be confusing, so it’s important to understand the difference between diesel fuels.

Off-road diesel fuel is chemically identical to regular diesel, but it is dyed red to distinguish it from normal fuel. Rather than being intended for off-roading use, this dyed fuel is exempt from standard on-road fuel taxes and is meant for use away from public roadways such as agricultural or industrial use.

Although the terminology is confusing, you shouldn’t use this tax-free fuel in your off-road vehicle. Red diesel isn’t for off-roading.
