Propane Autogas vs. Other Fleet Fuel Options

Written on: November 6, 2023

Autogas is generally cleaner and more affordable than diesel and gasoline.

We talk to commercial clients daily about the most affordable, safe and eco-friendly way to fuel their fleets. These include companies and municipalities with:

When people think of decarbonizing vehicles, they often leap to electric vehicles (EVs), but there’s a more cost-effective and dependable option than electricity: propane autogas.

What is propane autogas?

Propane autogas vehicles use the same propane you use in your home and appliances. Indeed, the Alternative Fuels Data Center says that propane is the third most common engine fuel in the United States, with roughly 60,000 propane vehicles currently on the road in the U.S.

Propane autogas is stored in a pressurized tank similar to a propane cylinder. The fuel is released as pressure is eased and travels to an autogas engine for combustion.

Propane autogas has significant advantages over diesel, gasoline and electricity.

Environmental Impact

Propane autogas burns much cleaner than diesel and gasoline. This is a considerable benefit for the planet and the air people around these vehicles breathe:

Finally, autogas is safer and cleaner in the event of a leak. Gasoline and diesel leaks can cause significant environmental hazards. Not so with propane, which is non-toxic, does not harm soil or water and typically dissipates into the air.

Autogas’s CI is also dramatically lower than grid electricity in Wisconsin. Our power grid still relies on coal and natural gas for generation, which is far from green.*


If you want to move away from gasoline and diesel, you’ll be amazed at how much more affordable autogas is than electrification. Conversion costs are comparatively low, and you don’t need to install EV charging stations in your business.

Propane is typically about 50% less expensive than gasoline and diesel. Even accounting for conversion costs and propane’s slightly lower fuel economy, you can expect much lower fleet fueling expenses.

Additionally, autogas vehicles run cleaner than gas and diesel engines. That reduces wear and tear, prevents breakdowns and extends the engine’s lifespan. And unlike those other fuels, autogas won’t gel in our glacial Wisconsin winters. We’ve found that switching to autogas can lower your maintenance costs by up to 50%.
