E10 fuel and other matters

Post by grahamemmett »

The Federation of British Historic Vehicle Clubs - to which the DLOC pays a handsome subscription, has some information on its website that somebody more cleverer than me might want to interpret.....

That FBHVC article is a very interesting read, right the way through.

I'm not sure what there is to interpret as it's very well written.

The salient section on ethanol can be found by using ctrl-f then putting the word "relating" (without quotes) into the search box, and then the browser should jump down to that key area on ethanol. From what I've read in other threads on this forum it's sort of summarised there.

The April DM has an article about the ethanol changes in September this year.
It seems that 95 octane fuel will normally have 10% ethanol and 97 octane will be 5% ethanol and classic car owners will be advised to use 97 octane "super" fuel.

My SP250 has been running very well on 95 octane unleaded fuel so will I need to adjust the mixture or advance/retard? I only do about 1500 miles a year so perhaps the increased octane in super won't be a problem.

What changes are Tesco planning?

Hello John,

I suspect Tesco may drop their Momentum 99, which will be a pity, replacing it with a 97RON 5%E and adjust their 95RON to 10%E - pure speculation on my part.

One thing is for sure, the juggle - be it Tesco or elsewhere - will catch many a folk out with incorrect E grade fuel being used.

Regards.

I suspect the critical element will be that, once "Super Unleaded" becomes the only E5 fuel left, retailers will need to see a continuing demand for it which justifies selling it on the forecourt. I think we can assume that there is a decent demand for it even now otherwise it wouldn't be there but once the E10 95 octane is introduced, if they see steady and even increasing demand for the E5 product, it is likely to stay available for a good while to come.

I suppose it's not unlike the supply of cellulose paint, we were lead to believe it would be likely to disappear but the retailers of it don't seem to have any shortage of it even though it is supposed to not exceed a very small volume of paint sales. It's worth remembering too that there are so so many off road petrol engines which will be likely to be with us for a very long time and even if electric cars do rise in number, the off road use of petrol will at least be a continuing demand.

Just as an aside on the electric vehicle line, it never fails to amaze me that when a journalist on the box is trying out an electric car for a "green" article, the thing they always comment on is how super the acceleration is. As I chugged round the centre of Dumfries this morning in its 20 mph zone, I wondered why anyone would reasonably want a car to accelerate even faster than the modern petrol and diesel stuff ? Given that the average human is used to seeing a vehicle in the distance and makes a decision as to the expected time it will take for that vehicle to impact them if they step onto the road, I think we're heading for a lot of accidents with the super quiet super fast electric cars with close to zero vision through the slits called windows that are way above child and domestic animal height.

I've just discovered the good news that, in some parts of the country, Esso Synergy Supreme fuel contains no ethanol.
Here's a statement from the Esso website:

"Although our pumps have E5 labels on them, our Synergy Supreme+ 99 is actually ethanol free (except, due to technical supply reasons, in Devon, Cornwall, North Wales, North England and Scotland). Legislation requires us to place these E5 labels on pumps that dispense unleaded petrol with ‘up to 5% ethanol’, including those that contain no ethanol, which is why we display them on our Synergy Supreme+ 99 pumps.

There’s currently no requirement for renewable fuel, like ethanol, to be present in super unleaded petrol although this could change in the future, in which case we would comply with any new legislation."

I believe that the hysteria about ethanol ( more properly called ethyl alcohol ) based fuels is just that . For the first 250,000 miles of my motoring career , from about 1962 to 1973, my preferred fuel was Cleveland Discol which at one stage was a blend of 75:25 petrol to alcohol. I never suffered any fuel system problem in a number of cars, some of which were pre-war

National Benzole Mixture and Regent Benzole Mixture were common in the 1950s and I'm sure my dad used Benzole mixture without any known damage, but I'm not sure if benzole is the same as ethanol.

I think the Benzole mixture was made from synthesising coal into petrol.
