Duffer is I believe a pilot.He’ll know the answer to my question,it was suggested to me that running aviation fuel through your engine periodically and especially when storing over winter cancels the negative effect Ethanol has on older engines due to “ extra additives” it contains.Fact or fiction?😁

I'm not sure about the additives, but I'd be interested to know too, I do know its much higher octane and thats why the motocrossers love it. they tend towards tunes with high compression which makes for a very responsive engine but takes you very close to detonation. somehow (gawd alone knows how they did it, honda's genius strikes again) honda got the crf450 to run ok on pump p*ss with a 12.5:1 compression ratio, that has to be right on the limit

How it works chemically I have no idea. Someone will though. Just don't mix it up with Avtur, which is only OK if you have a jet....🤑🤪

Or a silver CB250N deluxe of course….

Now that would be funny.

so would a jet starter motor run on Avtur? I really should stop thinking thoughts like these...

A jet needs to spin to start. There are a number of ways to do this but one is from a small engine often in the tail called an APU auxiliary power unit. This is a very small turbine engine itself, and it runs on avtur, and it is only a matter of time before someone fit's one in a bike...... Over to you ?

crazy but it could be fun to try, wonder what my insurance would make of it

The problem with a turbine may be the size of the reduction Gearbox you would need for direct drive.....Could maybe set it up to burn off some separated Ethanol, and have a stainless tank.

I read this on the VMCC Facebook forum page posted by a member NOT the club
An interesting read. Ethanol fuels - back at the begining of August at an event at Brooklands, I had an interesting conversation with someone who works in the industry at Esso’s West London Terminal near Heathrow. They have their fuel supplies pumped in by pipeline from Southampton and then they distribute by tanker across much of Southern England. Key points were: 1 – The Esso Super they supply contains no ethanol even though marked as E5 at the pump. 2 – E5 95 RON fuel is 91 as a base and the ethanol added brings it up to 95. 3 – Avoid E10 if at all possible and if you have to, don’t leave it unused for very long. 4 – E10 is giving them problems in the depot as it’s attacking the seals used in their equipment. 5 – Tesco, Sainsburys & ASDA get their fuel from the Esso Depot and their Super Unleaded is pretty much the same as Esso’s. 6 – Esso's move to E10 is behind schedule due to covid delays and technical issues. 7 - Esso pumps marked as E10 are dispensing E5 at present. Other interesting points were that the pipeline from Southampton transports all types of fuel under high pressure and they use some clever techniques to keep them separate. Since being installed in the 1960s, the pipeline has eroded, they have to use filters to capture the metal particles. There is a separate pipeline for Jet A1 aviation fuel as contamination of that is not good. Now this is all based on an ad-hoc conversation but the comments about fuel types were interesting. Removing ethanol from normal unleaded using an ethanol removal kit looks like it could give a pretty low octane fuel. 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.

Good read this, with some interesting points. Predictably, I have found it a pointless exercise asking the workers in the petrol stations what their petrol actually is. I was in my local Tesco station and their pumps now have the E10 unleaded and E5 super unleaded marked. In the ESSO around the corner, theirs is the same too. From an ESSO point of view, it would be great if they could actually say which petrol station has what. In my area, Shrewsbury, I am close to North Wales and what I call North West England (North England?), but fall into the West Midlands! Where does the supply for my ESSO garage come from? Who knows and who actually cares apart from those that have old vehicles. I am going to go along the route of using super unleaded, changing the fuel lines and draining down the tanks. OK for the bikes, but for the cars?
