Ethanil removes ethanol from your fuel

Easy kitchen-science fix for an increasing problem

Over the last couple of years fuel quality has become an increasing problem for classic motorists. Especially the addition of ethanol to petrol has raised a lot of cause for concern. A lot of old-fashioned rubber seals and gaskets undergo rapid deterioration when they come into contact with ethanol leading to severe leakage, fuel spills and firehazard. The industry has reacted by fuel addition systems or so called ethanol-killers. Ethanil however is different, because the product tackles the problem at the root, effectively removing all ethanol from petrol. And it does this by some very basic kitchen-science.

Ethanil makes good use of one of the key features of ethanol: its ability to bind with water. Petrol   (gasoline) itself does not bind with water, so in theory it should be able to separate the ethanol from the petrol using simple tap-water. Ethanil does exactly that. The system basically consists of a plastic Jerry Can with a strategically placed tap. Fill the tank with petrol, add a specified amount of water, with the aid of a supplied measuring cup and give the lot a good, sturdy shake. Leave to settle for a few hours and pretty soon you will see the ethanol and water gather at the bottom of the tank. The tap makes it very easy to separate the petrol from the ethanol-water mix.

The Ethanil system is available in two versions; a basic and a deluxe. The deluxe version comes with the Mr Funnel Fuel filter that actively filters all possible water particles out of the fuel. And to be honest, we would definitely opt for the latter, as you do not want to be pouring any left-over water into your gas tank.
On a day to day basis it might be a lot easier to add a ethanol-killer to your fuel-tank, but we at Classic Proof definitely appreciate a simply engineered solution like Ethanil. For more info on the product, check out their website on
