2-Pack Ethanol Test Kit - Spill-Free Wide Mouth E85 Tester with Bold Markings, Compact Design for Hundreds of Tests, Accurate Results in 5 Minutes

Works great, got some gas I thought may have been higher in ethanol and after testing it was actually about 7.5%

Simple yet effective

Came in as described. Only thing I wasn't real fond of was the size. They a relatively large for using as an E85 tester which wastes some fuel. The full scale graduations are nice though.

It's easy to use and I was able to easily verify the non-ethanol fuel had 0% ethanol and the E-10 fuel had 10% ethanol. It's good to know you're getting what you pay for.

This is the best! No more guessing and hoping for the best. Using this tested to check the ethanol percentage is a game changer for my build. I have a F80 M3 that loves the corn. I would buy again

This worked as designed and verified that the Non ethanol gas I purchased was indeed ethanol free. Now I can breath easy and not worry about damaging my lawn equipment!

dont leave this item on the dash of your car. I took them out of the package and set then on my pickup dash for about an hour and they distorted to the point where they are of NO value.

Great product, on time
