E30 Zone

Does anyone know about the new E10 fuel arriving in the UK later this year? I heard that it perishes older fuel lines so I’ll change them as mine are probably due for an overhaul. I haven’t heard anything about compatibility with engines etc.

Is there anything else we need to be aware of with this 10% Ethanol fuel?

i've heard it's coming in some time this year but dont know when,

as for it perishing older fuel lines? i replaced mine with teflon/ptfe lined braided steel ones that are E10 safe just incase.
thats all i know so far, but i'm keeping my eye out for anymore info about it.

I use Esso Supreme which has no ethanol and will continue to be so post E10 rollout.

My fuel lines were replaced with genuine BMW ones last year and I assume it will be E10 safe but don’t know for sure if the spec has been updates since 1990.

Been using E10 for the last 6 years...The rubber fuel line sections are all new obviously, otherwise zero issues.

Everyone in Europe is in the same position, seemingly no issue...there sure ain't piles of old E30's on the side of the road !!

E10 fuel is very common here in Australia, but it's only a replacement for 91 so higher octane fuels are also available.

According to the fuel police (Federal Chamber of Auto Industries), all BMW models post 1986 can use E10 fuel:

Edit: but there are a few reasons why you might want to stick with "normal" unleaded (you can still buy RON91 fuel here, it's just more expensive than E10).

Only problem I have with E5 is that if the fuel is left to evaporate it leaves a gooey green deposit so I have to clean my carbs, jets etc on the kit car that stands for ages.
On the BMW I think it might be a good idea to buy a meter of fuel line and fit new anyway after 33 years along with a filter..

E10 fuel is coming from September this year as I understand it. There is a list of car manufaturers on this website showing the compatibility with E10 fuel. BMW is cleared with E10 in all models. I am not so sure if it applies to very old models using carbs.

As I understand it problems arise with brass carb floats if they have any soldered joints. If its got plastic floats then I believe it should be OK. Most of the E30s on this site are fuel injected so it should be OK. As a precautionary measure it would be prudent to replace rubber fuel hoses as ethanol has been known to attack rubber and there have been some cases where classic cars have had fires. I am not sure if OEM fuel pipes originally supplied by BMW in E30 when new are compatible.

I have started using Esso supreme+ which does not have ethanol and is 99 octane. My experience suggests the car is now more responsive. I was using BP ultimate before and only changed it because I thought the petrol seem to have a different smell and may be ethanol content had gone up.

Sorry forgot to put the link:

I've just replaced my fuel hoses. One had deteriorated to the point where fuel was leaking. I'd guess it was age-related, but for the conspiracy theorists out there I did use E10 a couple of times, so it could've been that!

Advice from my local mechanic - "E10 won't cause you any major problems, but it's crap fuel". He also told me he won't use anything less than 98 in his E30 (which I note is little more than a rolling shell, so I don't think fueling has been a big issue for him).

The guy who looks after my cars at our house says dont use anything below 99 octane (shell ) and I definately notice the difference in the 325 e46 in performance ,MPG and response .
Going in the e30 very soon.

The e30 won't perform any better with higher octane. The ECU can't adjust for it.

Correct. You can however get performance chips from Mark D'Silva on R3VUnlimited that take advantage of high octane fuel.

To be honest I run all my cars on super market fuel because the 'brand' stations near me are all on major roads and take the absolute piss price wise. I am doing a test woth m M140 over the next couple of weeks to compare the Shell and Sainsburys locally.

Asda price fuel FTW

The important thing is that for those whose vehicles cannot cope with E10, the 98 grade petrol will continue to be E5 as a protection grade.
I had a discussion with the previous fuels expert, and he told me that was very little difference between supermarket petrol and mainstream brands, it has certainly never given me any trouble in my 325i.

It's also important to note that Esso synergy supreme+ 99 continues to be completely ethanol free in most of the UK. That's what I use for peace of mind.
