Great post from Mustang Manic on the ethanol debate raging here in the UK

Alcohol Free Zone – C2H5OH

Posted on October 24, 2021 by Mustang Maniac

A few of our customers have asked us about “Ethanol” in the standard UK’s petrol on their Mustangs. Yep, that very word ‘Ethanol’ the chemical formula which is ‘C2H5OH’ strikes fear into any classic car owner. Ask us the chemical formula should be ‘DEV1L’s juice. Many questions since the switch over to E10 in September this year here in the UK. A few problems have arisen from their old fuel lines now under attack the Ethanol, and leaking. If you’re not careful, you could be in for some big bills! Despite what people think and say about us, here we are going to try and stop you spending out large wads of cash with us believe it or not.

We have done a little research and collated some pointer and facts for you;

  1. Ethanol is an alcohol substance, those properties will dry out the rubber components in a fuel system. This leads to cracking and brittle fuel lines, floats, seals and diaphragms, caps off’s etc.
  2. Ethanol is corrosive when in comes into contact with certain materials within the fuel delivery systems and its related storage. This will be things like the flexible joining parts, rubber compounds and also the more worrying aspects of the zinc and aluminum alloys used in carburetors. Yep, your nice new shiny carb will slowly disintegrate inside out.
  3. Ethanol is ‘hydrophilic’. In other words it loves water. Because of the water absorbency properties, the water content enters fuel containers when they are filled up, that’s your fuel tank, jerry cans, plastic petrol cans etc. Once water is in the fuel it forms a chemical mix that causes corrosion of internal parts. As the fuel level in your fuel tank or container drops, water condenses on the cool surfaces of the container, droplets form and run down into the fuel where the ethanol absorbs it.
  4. Ethanol is also a solvent in older or classic car engines. Not such a bad thing you say? Well, the ethanol begins dissolving the varnish and other deposits in your tank and fuel lines. These deposits are then carried to the carburetor or injection system where they can clog the small or tiny orifices involved. The results of which could cause all sorts or problems, over fueling, fuel starvation, stuck floats, blocked jets, engine stumbling, idle issues, pick up issues and so on.

  1. One man and his Mustang – UK – I'm just a man with a Classic 1966 Ford Mustang Coupe and an ever increasing collection of car detailing products to keep it clean. When I first started this blog this is what I wrote: "I had bought a project car that had been neglected, set fire to, rusted and abused. As a result of all that the car needed a bare metal strip down, a nut and bolt restoration." Four and a half years later the car was completed, on the road and shown at the UK's premier Classic Car Show, everything that was done to my car is documented here. I now have the privilege to drive one of America's most recognised cars and a true Icon, the Ford Mustang. I'm still sane after the blood, sweat and tears, so would I do it again? Oh yes!

    Excellent information.
