2 Pcs Reusable Ethanol Tester E85, Wide Mouth Fuel Pressure Testers Bottle, Gasoline Oil Analysis Kit for E85 Ethanol Levels to Maintain Peak Engine Performance, Clear Results in Minutes

Wet simple method to check for ethanol content in your gasoline. I used to use plastic bottles and guess about how much ethanol I had. These are simple to use and give a fairly accurate measurement.

This works fine and give a very accurate indication of the ethanol level but it take quite a but of fuel which is then discarded. (It is possible to pour off the "ethanol free" fuel and return it to the fuel jug, but its a little sketchy to add water to fuel, then use it!) I'm looking at other products that might to the same "go/go no" test without wasting so much fuel. I'm not doing laboratory science!

Fast shipping. Love being able to test fuel.

Works as advertised.

Works as advertised.. easy to use, put in some water, fill with e gas, shake and read percentage...Only drawback is thag cap doesnt seal tight and leaks.when shaking...Plastic bottle deformed from sun when left in car in Texas sun.

I chose this kit as it used smaller amount of gas than many. I've been able to determine how much "non-ethanol" gas I need to pump first to clear the line at a station that uses a single delivery hose for delivery. Not that I appreciate paying $1 a gallon over premium 10% ethanol gas. It take 2 gallons get to what I'm buying. The bottles have a more graduated scale than many others too. I would have preferred glass over plastic for a longer reuse life. Ethanol gas is the worst thing ever for gas that is going to be left in small engines including generators. This kit was a small price to pay to protect my farm, motorcycle and vehicles that are stored more than driven.

Both containers’ threads stripped out under very light tightening and now gas leaks everywhere. Very cheap quality. Should’ve tried to find glass

This item was something that I wanted to try, ever since the tags, identifying the gas type went missing on my gas cans.I tried it out and found that it was indeed easy to do. The containers were also easy to clean and the caps fit tightly, which makes shaking the contents mess free. PET should be impervious to it being exposed to gas and the gas additives.I do suggest that you let the mixed contents sit still for more than the recommended 5 minutes, as there seems to be other ingredients in the gas that may also separate out as another smaller layer between the gas on top and the water on the bottom.Note: I used distilled water so I would get the clearest results possible, though other water that is not as clean could get you by in a pinch.
