With the looming changes to E10 happening soon, I need a bit of advice.  where i am (Orkney), we dont have access to super unleaded, which will be staying low ethanol content, so i will be forced to use E10.  Basically, are the ethanol fuel protection additives work, or will i need to start replacing rubbers/seals to suit the new fuel.  The fuel hoses would be easy to replace, but more worried about other fuel related parts (mainly the carb). Just wondering what people think

 

I also have a 1991 T25 1.9 petrol, which will also have to go through the same

 

 

cheers

Change the hoses to Ethanol resistant ones ASAP.

I have just changed some marked suitable for unleaded and they were rock hard and not very old apparently.

If you have a mechanical fuel pump be aware that if the diaphragm failed it would fill your motor with petrol so that may be something you need to look at.

I would trust a 1990`s factory fuel pump over some of the s**t available but Burlen may have something.

As for the brass and alloy I don`t think there is a lot you can do about it other than completely drain the fuel system if you lay it up over winter.

The likes of Fuel Set by Liquid Engineering claim to remove water from fuel systems as well as varnish and gum but if it does remove water where does it go ??.

Agree with updating hoses. Had the one off the tank crumble and leak fuel everywhere in boot and on garage floor. Do entire run to carb.
The carb itself should be OK as only the float and its shut off needle are not metal. Generally these are durable plastic (float) or Viton rubber (needle sealing tip) and should not be troubled.

For Winter lay up, best to keep tank near full to reduce water condensation within. Use some fuel storage treatment as these stabilize water absorbance.

Won't you still be able to get E5 at the pumps in Orkney? As far as I'm aware our petrol stations up in Shetland are keeping E5 available. There has been a lot of talk about trying to get one of the stations getting super unleaded but I can't see that happening to be honest.

Apparently the tanker ships that supply Orkney, Shetland and the Western isles are not suitable for transporting E10, therefore we have an exemption. https://assets.publi...onsultation.pdf

There was a thread on this recently;-

 

https://www.theminif...t-year/?hl= e10

 

Some issues I've noticed from it is that it seems to have a lot of water in it, be it from production or storage, it's there. I've notice that causes accelerated rusting of our steel Fuel Tanks and corrosion in our Carbs (and no doubt Fuel Pumps too). I've also heard of corrosion in the fuel lines. It also causes rubbers in the fuel system, hoses and other parts, to crack, unless they have been up-dated to the most recent E compatible parts.

 

I also only found out yesterday that it's not compatible with Nylon 66. Our locally made Minis and Mokes had Nylon 66 fitted for the Fuel Tank Breathers / Overflows and Mokes from November 1979 were fitted with Nylon 66 Fuel Lines. Oh the joy.

 

Straight Ethanol is around 30% by volume, Oxygen, so when mixed with Petrol at around 10%, it will lean your fuel mixture by around 3%. On top of this, the Stoichiometric Air / Fuel ratio for straight Ethanol is around 8 or 91, so further fueling is needed, even when mixed with Petrol. Also, it has a slower burning rate so some Ignition Advance would also be needed.

In our cars, I'd suggest avoiding it. It's Cat's Pee. It's perfectly fine if the car was designed for it from the outset.

There's a bit of info available on how to easily separate most of the Ethanol from E Fuels.

We only have standard E5 at the moment, wouldnt imagine there is much demand for super unleaded.

Ah cool, i will have a read. would make things a lot easier
