E10 fuel issue

Just putting this out there. The 961 did not take to the new E10 fuel, however I should have thought about it as my 961 has been mapped and ‘decatt’d’ . The first time I filled her up after the introduction of E10 it started pinking under load. After stopping the engine it wouldn’t start without smoking and spluttering. Once I drained the tank with a syphon and refilled with’ super unleaded’ E5 it struck up and performed as normal.

E10 = bad news.

I'm still waiting for Esso to get back as to whether Supreme+ with the red label will remain E0.

If not then it's 4* E0 leaded racing fuel for me and that is not cheap!

I have yet to see a motoring organisation or club campaigning for E0.  Have they all been Green washed and on the agenda?

My understanding is that  Esso Supreme +  at the worst will  go to E05 .   However  none of the availiable fuels are  accurately mixed   in manufacture . Its done at the point of loading the road tankers. So E05 could easily   be topped up to  be E25 by some  dozy  newboy . Try to run your 1931 model 20 on that. .If an airliner can have 1000% too much additive  put in the fuel that stops the engines (and it has been done) then anything is possible once you allow pollititions to  design the systems.(which effectively is what has happened).  You could try Aspen fuel ?.Fill up at the local Garden Center  ,  That sounds green and good for the enviroment !.

From my own experience on Sunday, after filling up with E10 at a local Sainsbury's petrol station, my machine runs with no discernible difference on the new fuel but it can strip the paint off the tank in half the time of E5 if the tank is over-filled. I suppose that is one of the consequences of using and riding a machine as opposed to taking it everywhere on a trailer...

If the tank is full its worse on a trailer as no fuel other than what leaks is being consumed. Need to get my 5 gal jerry can filled quickly or my lawn tractor, quad bike and digger are going to need surgery now rather than in a years time.

Just in from ESSO..........

Thank you for contacting Esso Customer Care.

 

Please be informed, we have no plans to change the Ethanol content of our Esso Synergy Supreme+ 99 fuel, and will continue to provide ethanol free fuel in ethanol free zones.

 

Thank you for your patience and understanding.

 

Kind regards,

Whilst it won't help day to day on the road, if you are like me and no longer ride during the salt season and are worried about the corrosion in the tank and carbs, there is a reasonably cheap alternative for the carbs at least.

1/ Drain down the fuel tank and store fuel in sealed containers or use it in your car if it is a petrol one. Drain carbs (or run engine until fuel is used up).

2/ Add around 1 litre of  white spirit into the tank and open the fuel taps. Back in the day when cars had carbs, white spirit was used big time on carb flow benches when setting up the carbs (it is a lot less explosive than petrol) and they could be left on the shelf for months without any damage occurring to them. All rubber diaphragms in the accel pumps were unaffected, floats and needles were ok, plastic pipes and seals were fine too.

3/ Either tape over the breather hole or sandwich a plastic bag between the cap and tank filler hole to stop air getting in.

White spirit is not hydroscopic so no water would be attracted in. It isn't silly money to buy either.

Come salt free time, drain it out from tank and carb, revert to normal fuel and away you go. 

Regards,

George

My local Tesco filling station has had the regular unleaded pumps marked E10 for several weeks.  I queried this with the staff, because my understanding had been that the change would not occur before 1 September. The staff explained the pumps had been relabelled early and did not know why, as they assured me that the fuel is currently still max E5.

So just because a pump may be marked E10, it does not mean that is what you are getting - for now anyway.

Has anyone any idea of what or where an Ethanol free zone is?

'Please be informed, we have no plans to change the Ethanol content of our Esso Synergy Supreme+ 99 fuel, and will continue to provide ethanol free fuel in ethanol free zones.'

Hi Al,

No problem with this and you can get Esso E0 down your way...Supreme+ with the red label.

Easier for me to tell you where the ethanol zones are:

Devon & Cornwall

Teesside:  But beware, this goes as far South as Ripon, North Yorkshire but not Harrogate.

Scotland:  All of Scotland as far as I know.

I hope this helps.  Use it or lose it... (Bit like cash really)

The IOM is a real  ethanol free zone.  Here the Esso pumps will all have E05 or E10 stickers  although the fuel at present is EO  and E05  as Neil says.  I have had to switch garages for my regular top up as my local  sometimes fills up the Synergy plus tank with  the cheap stuff  just to make a bit more money. They were also likely to use your credit card details to book a flight home. Tried it on me once. Stay alert guys!.

Yes, Robert, IOM not in the E zone. I was told it was because the storage tanks are not E proof.

I spilled a bit on my tank at the MGP 2017 and the paint didn't come off when I cleaned it off.

Got to have two jabs to go over there now. I won't go again on principle.

The E5 sticker is there by law but it is supposed to mean up to 5%, which includes 0%.

PS: I try to always use cash, as above.........

HI Neil,  two jabs,    I read that as two jobs !!.    When in the Island  i heard that lots of bikes were not performing as usual  and the fuel  was the suspect.  Usually too rich. I do find that switching from E0 to E05   (usually not  intended)  changes the  fueling.

Hi Robert:  Two Jobs? It will be a hell of a job getting that lot out of the body. Must be a nightmare for our poor old engines to try and run with different fuel, why I stick with E0.

Peter, my vmcc Chairman a couple of years ago suggested buying a gallon of Aspen to put into empty tanks, bit in each bike over winter and would also allow some start ups.

No need of course with E0 but good for riders in the E zones. £14 a year is cheaper than new hoses and a rusty tank + blocked fuel filter.

Just a thought...

What’s in our Synergy Supreme+ 99 premium petrol

What’s in our Synergy Supreme+ 99 premium petrol

 

Our Synergy Supreme+ 99 petrol has more cleaning power than our regular petrol – and includes molecules whose job it is to reduce the friction in your engine helping the moving parts work more efficiently.*

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.

If you have a bike that is already running a bit too rich with sooty plugs a switch to Synergy Plus may make it a little richer .  It did that to me.

not quite Robert. .....

Where Ethanol is added (along with other additives that change fuel from basic I.e. little of no additive supermarket fuel through standard oil company to super grades) at the loading racks there is no human. so driver input, this is entirely high tech mechanical.  The tolerances are extremely tight , So if the injection of the Ethanol or additives goes out of tolerance then loading is terminated. So E5 is E5 and so on..  Never a home brewed mixture courtesy of a dozy tanker driver.  

Now where dozy tanker drivers do get it wrong is when they get it all mixed up at the filling stations, but that is always more problematic - petrol grades never mix well with diesel and vice versa.....   Fill up with a crossed over cocktail and you will never get far from the filling station.
