E10 petrol is sold at the pumps your standard unleaded and you know how that messes with are old bangers, so in 2021 they are giving us E20 that means 20% ethanol in unleaded.super unleaded is ethanol free and staying like that .so if you are intending to stand your bike drain the tank and carbs E20 will soak up moisture like a sponge.we are saving the environment you know

Any thread that is started regarding oil, petrol and even tyres I have decided to no longer get involved in. That said, I know we can discuss things on this forum in a more adult manner, but on facebook things just get silly whenever someone brings up these subjects (on the BSA page for example).......grown adults start hurling insults like children. But that's facebook and most of you know my thoughts on that. Opinions are like a*seholes.......we all have one and they are not always the same.
It's a shame.....because I do like a good oil / tyre / petrol discussion. Maybe it's because oil is found in all three and is closely linked to the economy thus politics and people with too much 'vested interest' get involved......and things become heated.

You have blokes on there saying that the unleaded thing was all a con with the hardened valve seats etc... Then you have someone else saying it wasn't......makes my head hurt tbh. That said I have always used Super Unleaded in my bikes....the amount I fill them up it's just a no brainer to me. In the states I buy the highest ron I can which happens to be I think 91 here....again, the difference in cost / mileage covered to me is virtually zilch if I was filling up with 87. The extra outlay in cost would be virtually nothing over time. |

Another side effect of higher E rated fuels is that older petrol resistant seals may begin to leak and degrade, and that's not just old bikes, there's a running thread somewhere about the plastic tanks on BMW's won't refit correctly after removed because they warp and expand after long exposure to e20 fuel.

Forum sites are exilent for info nick but you need to be able to see the wood for the trees, most map bikes run fine on modern fuel most carb service kits and fuel lines are ethonal resistant. Brit bikes especially the high performance models like your lighting and my s r.they put high compression pistons and a sportier cam in to get more power no problem in the day of 5 star but today these engines are not happy. Pre ignition is the main problem .my s r I have fitted gold flash pistons and a milder cam so I have lost some hp that I will never youse .I have not faced a problem yet that can't be engineered out.but do not youse shop manual and parts books as holey bibles there are people on forums know more about a certain model of bike than the people that made them.youse forums for hints and tips not gospel

FWIW mixing ethanol in petrol actual raises the Octane racing , the same reason grass track and drag racers use methanol, it does have a lower energy density which means the compression ratio has to be increased to achieve the same power output . Which of course is the opposite of what most forums etc will tell you .........  |

Back in the day , if I had water in the fuel I would tip in some methylated spirits - same as ethanol it will mix with and absorb water and allow if to be burnt rather than continiously "blocking up" the main jet .

Up to 2013 unleaded had 0 to 5% ethanol now its 5% to 10% ethanol is 25% less efficient than petrol it's not me that says it will corse problems with older vehicles it's the aa and rac why do you think modern vehicles all now have plastic fuel tanks

I though we were on e5 and in 2021 they are starting to introduce e10 which is not recommended for anything befor 02 and since 11 any new car must be able to run on e10 |
