What is mogas?

Posted on Updated on

Answer by Thomas Zerbarini:

MoGas is motor vehicle gas or gasoline. General Aviation aircraft owners sometimes use MoGas instead of AvGas to save money. MoGas generally is cheaper than AvGas. Pilots flying experimental aircraft tend to use MoGas more than pilots flying manufactured aircraft.

There are issues that must be considered if using MoGas.

Using Motor Gasoline in Aircraft Reciprocating Engines

Also, check out the FAA Advisory Circular on using MoGas:

AC 91-33A – Use of Alternate Grades of Aviation Gasoline for Grade 80/87, and Use of Automotive Gasoline

MoGas may become a more popular form of fuel for General Aviation due to the fact that AvGas may become obsolete over the years. Aircraft engine manufacturers are already addressing the issue by making duel fuel engines.
