Awesome product. Mouth is large enough you don’t have to carry a funnel. Just got to have that good trigger finger if using the pump. 😂

These work great for finding out if the non-oxy gas that you are paying a premium for is actually non-oxy gas. By using this tester I found that it takes more than just pumping a quart or 2 from the non-oxy pump into you car before filling a 1-gallon can. with some gas stations it to 1-2 gallons into the car before it turned into non-oxy due to the one nozzle was serviced by multiple hose... one coming from each underground tank and the switch-valve was down near the tank... 50 ft. away! That'll gum up the carburetors of your seasonal machines.

Very useful. Before this, I had bought a tank of (what I thought was) ethanol-free gas for my 1964 tractor. On filling the tank on my tractor, it started raining gas all over the engine. My gas turned out to have ethanol in it, which dissolved the seals on the gas shutoff valve. It took a great deal of time and effort to replace that shutoff valve; this testing kit will help me to ensure beforehand what kind of gas I've purchased!

This testing kit worked perfectly as stated in their description.

Easy to read bigger opening a plus

Has your gas mileage dropped recently? I was looking for answers. My mileage dropped More than 10%. Thought that they had added fillers To my gas. As an engineer we prove it by testing. Test for less than $10 per test kit.. Ok test was simple and worked. Kit can be reused Again and again. Answer was E8% . Well within E10% range. The search continues…..

Did what it was supposed to do. Just a little messy.

Good Product
