Hundreds of thousands of cars could be at risk of damage from new petrol expected to be introduced by next year.
Earlier this year the Government launched a consultation into making E10 petrol the standard fuel in the UK from 2021 to cut pollution levels. However, experts are warning that the fuel is not suitable for classic cars and even some relatively modern vehicles.
Just wonder how we will be able to get the old style fuel, or possible will there be an additive available
To be honest Phil, our friends across the pond have being using E10 fuel in their old English classic cars for quite a few years now and I see little in the way of problems caused by it reported. This particular media story has been circulating in various guises for some time. Some of it stems from a list of cars compiled several years ago where manufacturers said what cars were compatible. I suspect in many cases the manufacturers were not prepared to comment on cars they ceased to make over 10 years ago as it is not in their interest. This article was from the Daily Express over 2 years ago! www.express.co.uk/life-style/cars/1009524/E10-petrol-car-compatible-check-fuel
Over the years we have seen these "scare" stories time and time again - unleaded, E5 and now E10 fuel. Then scare stories about old cars being banned, or subject to more testing etc. Me I just carry on regardless. I have never used any lead replacement additives in the fuel, I just fill up with what ever is at the pump, I never bothered using LRP. I have covered many thousands of miles in various old cars and not suffered any ill effects.
The only real issue I am aware of is enhanced levels of ethanol effectively dissolving certain grades of rubber fuel hose - easily fixed by replacing with E10 rated hose from a reputable supplier. Possibly the diaphragm in the fuel pump may be affected but to date I have not had any issues with those either.
One last thing - E10 allows for UPTO 10% ethanol, doesn't necessarily mean it will have that level and with recent events it may change the balance of supply and demand and delay the introduction.
The only consequence is you may have to adjust timing/mixture - but then you check that when yo service the car anyway - or should do!
I would like to endorse what Marshman says; I run a fleet of Standards dated from 1919 to 1956 and they all have always been fuelled on regular E5, since the time when leaded fuel was no longer available I have never used or found the need to use lead replacement additives, and on stripdown there has never been any indication of valve seat regression.
Club supplied Fuel pump diaphragms are all ethanol compatible and I have merely replaced fuel hoses with the right material.
The only issues I sometimes suffer from is overheating due to the increased volatility of modern fuel, but I get round that by lagging fuel pipes in the engine bay. Would someone like to start a debate about that?

I understand that with increased levels of Ethanol, the car will run hotter. I have only come across this problem once. A few years ago I took my 1935 Ten over to France for an excellent Club Holiday/Rally in Brittany that Brian and Dorothy Murrish organised. I filled up with petrol in Plymouth before getting on the Ferry. For the first couple of days, whilst I was using up the British fuel everything was fine. From the third day when I was using French Fuel, which has had increased levels of Ethanol for some years, the 1935 Ten was inclined to boil on hills, when it never used to over here. As soon as I returned home and reverted to British fuel everything returned to normal.
I also understand that most premium brand fuel contain very little, if any Ethanol. For the last two years I have been using Shell V-Power in all three of my pre-war Standards. I have been very happy with the running in all three cars and following a 20 mile round trip last Saturday in the 1913 Standard, using Petrol that was at least 10 months old, I don't even think it goes stale as quick.

Stevo has a valid point. But the reality is unless you are running on a large percentage of paraffin or any other "additive" I doubt they would ever find out - as long as it is clear paraffin and not the pink stuff. Still we could all apply for a license now "just in case" then we will be covered! VOSA (or what ever they are called these days) can and still do dip dip tanks around here looking for illegal use of red diesel!
I understand that the addition of paraffin to petrol is illegal, but HMRC may issue a licence to do it.
How would this affect emissions tests? MOT failure?
I wouldn't try it in your Dolomite Steve! It's OK in older lower compression engines all of which are exempt from testing other than, as misterm says, a visual smoke check. More modern "high" or "higher" compression engines will start to object if you start adding paraffin.
In many cases I think adjusting the mixture and the ignition timing may help keep temperatures down. People forget that modern cars with ecu's, knock sensors and closed loop control will automatically adjust ignition timing and the mixture to suit the fuel. A car with a carburettor and conventional ignition (including those with electronic ignition modules fitted) will require adjustment to run at its best on different grades of fuel, i.e. E5, E10, normal unleaded and super unleaded. Running lean or over advanced can make the engine run hotter, increasing under bonnet temperatures and increasing the risk of vapourisation problems.
In the "good old days" I knew when I had it all set up right because the inside of the exhaust tailpipe was a nice light grey colour after a long fast run. These days with no lead in the petrol you don't get that indication.
