Warning for E85 petrol in France

When going to France and need fuel there, don't pump the cheap E85 petrol, this is 85 % Ethanol, and will ruin older vehicles. It's marked "Super Ethanol"

Just a quick warning!



Cheers,

Lex

Re: Warning for E85 petrol in France

Super unleaded used to be the fuel with least amount of ethanol so it’s now not the case - at least in France

Some of the independent tests we undertook at my place of work back a few years now - with varying percentages of ethanol led us to conclude that with EN15 EN20 - the real fun would begin for manufacturers/ but especially us classic vehicle enthusiasts

Rubber perishing will be least of our worries with this rot in our tanks

This stuff is not Super Unleaded John, It's Super Ethanol!! Ron

Re: Warning for E85 petrol in France

Lex's cropped photo seems to suggest that E85 (85% ethanol) is also 85 Octane.

Belgium is as per UK, I think. 95 Octane is 10% ethanol (E10) and 98 Octane is 5% Max.

Yes Rik, I use the 98 Super Unleaded from an independent Esso station (not a supermarket) and add a dash of anti ethanol additive.

I've just ordered a new bottle of this. Ron

Re: Warning for E85 petrol in France

Up to the end of august 2023 Esso E5 contained no ethanol at all, at least in my area. I checked on their website. I bought 5 gallons and wintered my engines with it. My tuned Enfield 535 started much easier come spring. Apart from Ethanol being hydroscopic I don't have any problems using E10 on my 40's engines. I just don't leave it in for long periods. However it reduces the oil ratio in two stroke mix over time, leading to seizures, so I use E5 for chainsaws and mix no more than a gallon at a time. If it gets stale I dump it in my Series One.

I remember one two stroke MX manufacturer recommending mixing the oil and using in the same day!

Re: Warning for E85 petrol in France

In the UK we have 95(E10) 97(E5) and 99(E5)
I always use 99 octane if possible or 97 if it's not available. I had to put 95 in my Norton Dommie and International, and they struggled to go after. I had to drain the tank and refill with proper fuel.

I was running on E95 at the weekend and if anything, it seemed to go better.
Condensation would be my main worry if it caused corrosion.

Aloha,

Well actually, if you completely re-jet the carb your bike will run just fine on E85! :grinning: Fuel consumption increases with roughly 25 % and that is the ballpark where you start testing out jets.

A bit surprised you have no ethanol cars in UK? Was a big thing here in Sweden about 15-20 years ago, before electric was thought to be the future. Had a Saab 9-5 Biopower for a few years myself, 150 hp on gas and 185 on E85. Some people converted lawnmowers and such, for at bit of a cleaner "milieu" during garden work.

Best regards,

Simon

Re: Warning for E85 petrol in France

As M20s 16Hs etc run about 5 to 1 compression ratio they don't need high octane fuel. Their original jetting was based on something around 70. The only conceivable factor for a jetting change would be the viscosity. The octane rating is a red herring.

Re: Warning for E85 petrol in France

Aloha,

My post was about running a WD-bike on 85 % ethanol. As is the warning in the original message, E85 means 85 % ethanol.
