Pro-Series Ethanol Test Kit with 2 Reusable Testers for Ethanol, E85, Gasoline, Race Gas, Ethanol-Free Fuel Tester

WORKS WEL

Kit works as designed. Gloves and towels.

Anyone who has an E tune this is a must. I have a E30 tune and I need to know what coming out of the E85 pump. E85 isn't always E85.

Test your E85!!! Mine tested a minimum 70%

Cap leak cant get them tight, cheap tin caps, I swapped them out for 2 liter pop bottle caps and worked great stayed tight and didnt leak after that bottles are nice and are glass and etched.

Ordered direct from the Fuel-It website. Got this kit and a "skinny" version to see what one I like better.Shipping was fast.Laser etched glass is extremely easy to read.Found out I like both styles, but prefer to use the smaller and thicker one while testing on the road, the skinny but taller one for at home testing.With petrol in my area going well over 5 USD for a gallon of 91 octane 95 RON fuel, and E85 staying at a stable 2.99 USD a gallon, I decided to make an ethanol blended fuel that my vehicle can handle and a tune to go along with it.The fuel pump on my vehicle can't handle straight E85 and after a lot of research the fuel pump can handle around 50 percent maximum with some failures being reported here and there, so I wanted a 30 percent blend maximum to take advantage of being able to add a lot more timing with some tuning software.First test on the local E85 was just over 72 and just under the 73 percent line on both testers. Now I can do maths and find out how much E72.5 ("Winter" blend) to add to the 91 octane E0 fuel I normally get.Summer blend seems to be 75 percent Ethanol in my high altitude area.Remembering to add around 13 percent more fuel to compensate for the new stoich ratio of the E30 blend, I went for a nice drive and started to advance timing like a mad scientist. Advanced a few spots up to 14.5 degrees and almost every cell had 1 to 6 degrees added, that's a lot of potential HRSPRS

Super nice kit, love it
