Frequently Asked Questions: Propane Autogas Fuel

This is the first post of a two-part series to answer some frequently asked questions about propane autogas and autogas vehicles. Today we’re answering questions about propane autogas fuel.

Is the propane used for my vehicle different than the kind used for my barbeque?

Yes, there are several different blends and grades of propane and they are not interchangeable. Propane autogas is classified as HD-5, the highest grade of propane available, and is designed for automotive fuel use. Separate blends are also used for residential heating.

What mpg can I expect from autogas?

In light-duty vehicles converted to run on autogas, you will achieve about 90 percent of the miles you would from your gasoline-powered vehicle. In general, autogas costs less per gallon at the pump than gasoline, and autogas engines usually have a longer life and require less maintenance, so fleets often experience annual savings with autogas vehicles. You can also ensure that fuel efficiency is optimized by having a professional tune the vehicle. Most drivers do not notice any change in their autogas vehicle’s performance, and some even report experiencing a quieter and smoother ride.

Are SPADP funds used to promote any other alternative fuel technologies?

SPADP administrator Virginia Clean Cities maintains that consumers need more choices for fuel, but also believes that autogas is a viable alternative fuel solution for American fleets. It is less expensive than gasoline, cleaner burning and in abundant domestic supply. While practical and easily adoptable, autogas cuts greenhouse gas emissions and reduces our country’s dependence on imported oil. The Program itself is focused on getting fleets up and running on propane autogas.
