I think this should be made a sticky thread

I would imagine that the retail suppliers would be screaming louder than the likes of us with older cars.

If it corrodes the underground storage tanks, the cost of replacing them to be able to accommodate high Ethanol fuels would be horrendous :o

you will find that the tanks get a clean and protective coatings applied every so often

and they don't suffer the water absorption problem causing corrosion because the fuel is in their tank for a very short time.


Excellent thread, not to be ignored.

A good point ! some people (like me) have the same tankful for months during the winter when it doesn't get taken out of the garage if the weather is foul and the roads are salty.

Anyone know if Sainsbury has changed to E10 ?

I filled up from them for the first time about a week ago and have noticed that the engine feels 'different' maybe running a teensy bit hotter and the fuel/air mixture meter I fitted a few years ago is behaving differently ???

Thanks Yas, very informative ! I note that the article is dated Feb. 2014, I didn't notice the supposedly mandatory notification on the pump that the fuel was now E10 and may not be suitable for some vehicles !!

Maybe they're sneaking it in already :-\

A lot of what they say in that article about the detrimental effects fits with my observations of how my engine and Lambda sensor is acting but I'll reserve judgement for the moment.

I was right to reserve judgement !

This morning I had a go at the Lambda sensor and Lambda meter connections as well as the earthing points at the back of the manifold; they all looked fine but I gave them a light squirt of WD40 and plugged everything back together.

The engine now feels 'normal' again, the temperature meter is back to its usual rock steady 90 and the bar graph display alongside the numerical display on the Lambda meter is exhibiting the swings that I have come to expect rather than stuck more or less in the centre of the display.

It doesn't take much to screw up the Lambda sensor voltage since the sensor output of 0.45 Volts on a bog standard connector is pretty small !

P.S.  There was no indication from the fault light of anything amiss !
