Easy to use and has accurate results.
Love this kit. I quit using the ethanol gas in the lawn equipment and generator. When I purchase the non-ethanol gas, I pump 1 gallon into my truck, then fill the cans with the non-ethanol. When I get home, I always use this kit to insure there is only non-ethanol gas in the cans. Love how this works.

orks Great!!
Perfect and cheap for our shop to test the ethanol content of the fuel to confirm correctly functioning ethanol sensors. had one come in reading 30% but tested at 5%. Every serious automotive shop should have these to confirm.

Simple and works every time
Tried and true test. Always accurate as I have an ECA kit installed in my car. After testing and doing the math my ethanol content always reads exactly as I account for.

Great
Simple, cheap, and it works. Also have a nice sized lid, I’ve yet to pump into it directly but when pouring from can it seemed a good bit wide.

I like these. My previous ones were always glass and eventually would get broken. These are a nice plastic with easy to read graduations.
