Beware of French Petrol

French petrol stations are now selling regular unleaded petrol mixed with Ethanol, Called 95-E10, or Bio Fuel. This fuel is 90 percent ordinary unleaded and 10 percent Ethanol. Apparantly Ethanol is Highly corrosive and wears away metal fuel tanks.


Also if you have a vehicle which is difficult to atart when hot. avoid using supermarket unleaded fuel, use only branded fuel from the likes of Shell(v power) and BP Ultimate secondly use higher RON fuels which contain more Benzene and at least two combustion improver additives.

Re: Beware of French Petrol

Those are sweeping statements.

Some supermarkets have perfectly acceptable fuel. I believe Morrisons have Texaco clean system 3 which is about a good a fuel as there is out there.

Putting a higher grade of fuel in a vehicle than it is designed to run on is a waste of money and will not give any advantages if the motor does not have knock sensors to take advantage of the higher octane.

Fuel with 10% bio in it is used in lots of countries and if treated with a suitable corrosion inhibitor should be OK but will give lower MPG.

Re: Beware of French Petrol

I'm pretty certain it is here already, it was one of the big reason so many petrol stations had to upgrade their storage tanks.

Reminds me of the panic over unleaded fuel and how we were all going to have to change our cars, bikes, lawnmowers and bonfires !

Re: Beware of French Petrol

Ethanol is quite hygroscopic and it is possibly the absorbancy of water that causes the corrosion. I know that Petrol also absorbs water but it is less than Ethanol, petrol is also corrosive. No doubt somewhere out there is a company selling Bio-Fuel conversion kits -- ere Colin, you aren't diversifying whilst you are laid up, are you

Re: Beware of French Petrol

You have been filling your engines up in the uk for 12months with Bio fuel.
And your quite right about water getting into the fuel as well but before bio was introduced water dropped to the bottom of the tank. With bio the water attaches itself to the ethanol until it reaches a saturation point then both the water and ethanol drops to the tank bottom (phase sereration) not good but this is monitored very strictly and you have no need to wory about your engines.
