E10 Petrol

I have to agree that there is a degree of scaremongering over this and doubtless hidden agendas, but I also have the opinion that it is possible that a higher concentration of ethanol may degrade certain things quicker or even cross a threshhold of degradation which was not the case at 5%.

I was driving my 'normal' car in France and filled up with the cheapest fuel on one occasion - then realised that that was E10 not E5. Didn't think much more about it but the car now stinks of petrol so something is clearly leaking. The car is 26 years old.

I agree....but it will defiantly effect lots of classic car and bike owners.....and obscure things like small old light aircraft that can use motor petrol....also old lawn mower outboard motors....the list goes on.....as well as lots more risk of fuel vaporisation.

Lots have plastic or fiberglass petrol tanks....its a real head acre for many 1000s

From what I have read, the premium 97 or 99 octane petrol will still be sold as E5 for now.

Bet the price will go up.. it's expensive enough as it is

light aircraft still use 5 star leaded, if your worried about e10 make friends with a pilot

It is expensive, but most classics don't do a lot of miles.

Around here E5 in the super petrol....10p per ltr more....prob need it in our 2001 Astra 1.6p

I am not worried about the money, but in rural areas, Super unleaded isn't always easy to find.

If you have to drive ten miles in a Series to fill up, you burn a gallon on the return trip!

I'm sure we all understand the only reason behind Gov't drive for E10 is carbon emissions. Some pre-1995 vehicles will suffer from increased E volume but I'm certain it won't be as bad as the doomsayers are spouting. When E5 became standard the only people who really suffered were those who had poorly maintained cars/bikes, especially in the classic car world. So the issue wasn't seal/rubber degradation from E5, it was their fuel lines and seals needed changing because they work at end of life.

The Gov't has a ready reckoner does your car work with E10 here https://check-vehicle-compatibility-e10-petrol.service.gov.uk/manufacturer [if you drive a Subaru Forester, like me, then Subaru engines/fuel components from 1991 onwards are good with E10]

Interestingly, Todd @ Project Farm has completed a like for like test...the results are telling and I wonder if we're all being sold a pup?

it will be bad for those who dont use their vehicles much, especially over winter, the fuel will go off much quicker

Possibly, it depends where the vehicle is kept...in a dry and humid free garage or outside under an old tarp exposed to all weather. I'm going to empty the lawnmower this coming winter. Actually thinking of buying an electric robot mower at some stage and an old push n pull mower for when I get the urge for old skool grass cutting

They should drop all this shyte if they're going for the phase-out of new ICE vehicles, it's not really sound to bung ethanol in the petrol because the ethanol has to be produced at some carbon cost and also crop cost, plus you burn more fuel due to the slightly lower energy content so I can't really see it saving much in the way of carbon emissions.

I'm still using lead substitute additive, is that compatible? There don't seem to have been any problems with E5 but then I just don't know if there have been any problems...

Re. the fuel going off, I think I'll just make an effort to leave it empty if it's going to stand for a long time, at least with an electric fuel pump I could pump all the lines out too.

The Alfa is my daily and, according to the govt website, it's not compatible with E10. I figure, given its age and mileage, the engine will give up the ghost before the tank does.

Why are you using lead additive...are you expecting valve seat recession / what car?

It's a 1978 109 hard top with 6 cylinder petrol engine (6pot ) and as far as I know the valves/seats are not hard enough for unleaded, pretty certainly the exhaust valves at least.

Good plan, you really don't want to take any chances with valves on those, setting the tappets is a horrible job.

I use additive as well, on a 4 cylinder with an unleaded head. Every little helps, as they say.

Yes indeed and luckily the additive is still readily available.

Reading this I've suddenly realised there are two E10 threads on the go at the moment...

Only two?

We had a Daimler 4.2 come into workshop this week with a serious fuel leak and customer said ‘I not long filled up with e10, it must be that’
Sorry MrCustomer but I think coincidence comes into mind
