Mogas - Alcohol free or not?
By Dan from Liberal, KS on August 9, 2011
Airplane engines certified for mogas as well as older cars and lawn equipment can have problems running gasohol. This fuel tester lets the user know if the advertised 'alcohol free' gasoline is indeed alcohol free. If the fuel does contain alcohol will display the % of alcohol.

After showing this tester to my friends, one aviation enthusiast and two auto enthusiast now have one of their own.

I would recommend this item to a friend.
