Great product to check for alcohol in gas. This allows me to use high octane auto fuel.

This is a great tool. Ever since i got contaminated gas at a gas station claiming to sell ethanol-free gas, I have been using this little tester. Would not trust any gas I havent tested.

Apparently after 20 years with the same one I somehow let it fall out of the plane then drove over it. Replaced with this one all I wanted was a easy way to check for water and trash and does it works just fine.

391S Gasohol Tester

Fast shipping and as described. this is a shorter gasohol tester than Ive had before, but will work just as well as my old one from the 1970s

Perfect , works great for a DA40.. no pin required !

Simple device and meets my needs and cost was good

Flew Cherokees for years, then switched to Cessna. Suggestion: dont throw away the insert thingy. Its for Cessnas. If you do, youll have to buy another as I did. Also make sure the yellow handle is tight, otherwise the screwdriver bit could fall out. Slick, simple, etc.

This is a great tool for six bucks. Makes testing fuel very easy. Flat and phillips screwdriver tips, works with various types of gascolators, fits easily into a flight bag, and sturdy. What's not to like?

Nice product. Lets see how the quality is in three years.....

391S Gasohol Tester

It is no miracle, but a nice little compact tester. Gasahol test takes 5-10 minutes.

This device does exactly what it is supposed to do which is tell you the percentage ethanol present in gasoline.

Pain to use... but important?

Mike R Verified Purchase

391S Gasohol Tester

This is a product that requires 10 minutes of holding the fuel and water vertical, with no means to set it down, and no sealing top to set it aside, and no means of storing it vertically, so that you can get a reading of the alcohol sample % in your Mogas. Very, very poorly thought out device. Buy a Briggs and Stratton fuel vial mogas tester instead. All this is is a visual fuel tester for water in your fuel with a screw driver bit, its pretty useless as an ethanol content in your Mogas tester. Not going to hold it vertically for 10 minutes to get a reading. Dont buy it.
