Should we be worried about ethanol in fuel?

Start by using E5 super unleaded exclusively - the lower ethanol content is far less harmful than E10, and a damn sight cheaper than replacing fuel system components.

Will we see the results of your research Dom? I can't wait - the clock's ticking...

not very scientific, but a few years ago i drove to thailand and did a lot of b road driving in my 2005 JCW supercharged mini. the only fuel we good get in a lot of the rural areas was E85. it caused no problems with my car, but a friend who was with us in his 90's E36 M3 had a lot of trouble with his fuel pump and various fuel system leaks.

Thank you for the info Dom... What about the fuel stabilizer stuff that you can get in the shop. I try to use the 911 as much as possible (and the Boxster should be OK based on the fact that it is from 2001), but do worry about the winter when the car is parked up for 4 - 6 months :(

So without starting some sort of oil type debate, which fuels are best to stick to, a quick google seems to think that Shell V-Power and Tesco Super unleaded are both E5, so are these safe bets???

but loosely speaking don't leave your car parked up for a while with a lot of fuel in it.

 

Sounds more like without any fuel in it, even with the tank gauge on red the fuel lines, pump, etc are still going to be awash with fuel whether the tank is full or nearly empty.

Esso and ive read Total don't contain any ethanol (E0?)

V powers known for not being good when left in tanks for a while, not sure of exact reason as the 102 race fuel we use has a shelf life of 4 years as long as tins kept sealed and certain storage conditions are met.... But that is £4.10 a litre plus vat,

How long is "a while"?

This is getting more worrying by the minute. I thought I was safe with V Power in the tank - although I have started keeping a lower level in the tank than I used to. Trouble is, condensation then becomes an issue!

Oh well, I'll just have to use the car more often....but then there is the issue of salt on the roads and drivers sliding around in icy conditions, then there's the UV exposure in the summer cracking the dash and fading the paintwork..... :unsure:

My main concern is perishing fuel lines spraying fuel over the engine whilst driving along!

 

Has anyone changed their rubber fuel lines? which ones did you change? What should we look out for? symptoms? which pipes to check etc?

I though late SC's all had metal injector fuel lines ? Mine does. Are there other rubber fuel lines in the system ?

There has to be a rubber line connecting the hard lines on the engine to the body and there is definitely a rubber line on the fuel pump to the hard line through the body.

Correct Lewis. Flexible feed and return lines and pump hoses also.

 

It's not an issue yet but will become one.

Ok, so replace with what ? Aren't braided metal lines still rubber inside ?

I don't know for sure about ptfe but it's probably ok, just need to confirm first, but modern cars use a very similar plastic to ptfe so it's probably fine,

A quick Google turns up:

 

"We're also seeing a lot of PTFE sealing components for the seats in the valves, and those are highly compatible with ethanol." from this article.

 

But don't need to panic just yet, still some time to go.

Ha, I'm too old for panicking ;)

 

 

Why can't we just tell 'em to jog on- we don't want this ethanol stuff in our fuel?

:o

I would be more concerned about ethanol in my coffee....... :rolleyes:

 

Got this off the TR club website

 

BP Ethanol is added at 5% to unleaded petrol at all sites across the UK. BP Ultimate (super unleaded petrol) does not have Ethanol added, except in the South West of England.

 

Esso Ethanol is added at 5% to unleaded petrol at most sites in the UK. Esso Super Unleaded petrol does not contain Ethanol, except in the South West of England (Devon & Cornwall)

 

Shell Shell has repeatedly refused to answer the question. It is therefore an assumption only, that all Shell petrol should be considered to contain 5% Ethanol.

 

Texaco Ethanol is added at 5% to unleaded petrol. Texaco Super Unleaded petrol does not contain Ethanol.

 

Total Ethanol is not added to any Total fuel (including standard unleaded petrol). Except in the North West and South East of England.

 

Total have kindly provided a list of filling stations where E0 petrol can still be purchased. Click this link to download the list TOTAL E0 Fuel Sites.xls

Old rubber hoses can perish and split over time so if the presence of ethanol in unleaded means that this process is accelerated and new sections in resistant material are needed then I can't see this being a major worry. What is more of a concern is the potentially corrosive nature of alcohols on any steel, brass, zinc, aluminium etc.. components within a fuel system + bimetallic corrosion since they have reasonable conductivity (unlike staight hydrocarbons). I would have thought corrosion inhibitor additions could be made to and compatible with the fuel to minimise this risk?

although you would be amazed at how much of a modern production car fuel system is made up of plastic parts, so maybe not....

thats mainly down to cost and weight,anyhow before ethanol disolves our cars off the road the government will tax them off
