Club 80-90 Forums

I had a news article pop up on my phone stating that the current petrol sold at the moment (E5), will in a few years change to a type named E10.

Apparently current petrol grades in the UK contain up to 5% bioethanol, known as E5. The proposed E10 fuel increases the share of the renewable energy made using crops, to 10%.

Problem being it stated, that some older vehicles cannot run on it, so my first thoughts were, how will my 1.9 1990 DG cope with that, i'm guessing it wont?

I thought there might be a few posts on here about it but can't see anything. I guess, assuming petrol T25s cannot run on this fuel, that modified replacement engines will start to materialise over the course of time. I guess the topic will gradually be mentioned on here by owners who are worried.

Here I was thinking the government where trying to turn us away from Diesel engines

There was an article in the GEM breakdown cover mag covering E10 and it's effects on engines and not just in classic's.
They seemed think there would be quite a few adverse effects not just fuel lines breaking down as we know happens in our VW's with E5. But E10 attacking fuel tanks, carbs and engine seals in general. There were other parts of the engine mentioned but I can't remember them all.

Hello,

Replace your old rubber petrol hoses everywhere, including above the petrol tank
with silicone type from Brickwerks or similar.

We have been running E10 at 95 RON or 98 RON in Europe since 2002,

Never been a problem...

Hi thankfully did them all when I bought the old girl 2 years ago

Thanks Sarran, that's good info and reassuring.
Mine has new up to date fuel lines however not right on top of the tank. That said, the tank on mine needs replacing so will sort everything in one fix.

Just saw an item, can't remember where, that mentioned the new E10 fuel, as opposed to the present E5, not being suitable for all vehicles. Did a quick check but could not find any info on T25 era vehicles.
Anyone got any thoughts/info?

I’d strongly suggest filling up with Super Unleaded as that will still be E5 for another few years.

Unless you haven’t done so, a good time to change your fuel hoses to the Cohline product by Brickwerks as that’s 100% ethanol proof.

Hi,
Thanks. Yes I noticed that E5 will be Super Unleaded but wondered if T25 engines can/could cope with E10.
Fuel lines have been done.
PS. Usually running on lpg
 

Somewhere I have some VW original wbx petrol injection hoses dated 1994. Made by Continental and marked FKM...so they were suitable for ethanol blend fuel even back then!
The mechanical components will be fine, the metals used for the valves and seats are very high quality.
I wouldn't worry as long as you have replaced any old hoses with FPM(FKM)

Hi All, l too have read the article today, and was slightly concerned. I have a 1984 Holdsworth petrol with po up roof. I have looked at Gov web site on this and you go around in circles as our vans are not on the list of Vw vehicles listed by them. I have had fuel lines all changed. Does anybody know if this means we should go down the super unleaded route, or is the E10 fuel ok to use and will be ok for our vans? Many Thanks for any confirmation/ relies Regards

I also read that E10 can make starting more difficult on vehicles that aren’t used regularly. If that is true, then owners who mainly use their vans late Spring to Autumn would be advised to use E5 at least for a few weeks before laying their vans up.

As usual last minute government guidance that's as clear as mud. Thankfully mine's a diesel so I haven't got this problem yet, there are a few modern motors that are affected by this though so worth checking.

Jumping on this and changing direction slightly, well more than slightly.....what about my petrol lawnmower?

There is ethanol in diesel too I think? Its what causes "diesel bug" where airborne fungus spores and bacterias feed off the ethanol and condensation make a fungal mat on the surface of stored fuel. Or something like that. I'm not a biologist!

Its the hygroscopic nature of ethanol that causes corrosion in petrol systems and when the fuel evapourates it leaves ethanol crystal residues...
