E10 Crap

As far as I know. E10 was introduced in Europe back in 2013 (ish) and most manufacturers specify that their bikes are E10 compatible. See below some examples I found online.

• Honda for instance say all bikes made since 1993 are safe, while Honda said everything post-1993 is compatible, although carburettor-equipped models could experience poor driveability in cold weather
• Harley-Davidson say all bikes made since 1980 are fine
• BMW say every bike they’ve ever made will be alright as long as you get the correct octane.
• Yamaha and Triumph both said that all models from 1990-on are compatible with E10,
• Suzuki models made after 2002 are compatible with E10 and those made after 1992 might be but owners should seek advice.
• Ducati said that their Multistrada 620 and 1000 models were not compatible with E10 fuel, with tanks known to expand or leak in markets with ethanol-rich fuel.
• Kawasaki said that models made from 2006-on would be ok on E10 but advised customers not to use the fuel in bikes that weren’t specifically approved.

I've seen some E10 additives (protectors) in Halfords. Worth a try? It says multi dosage so I'm not sure how many shots you'd get out of 250ml bottle.

Initially I found them on MCN. motorcyclenews.com but a quick google search should bring up manufacturer's official website.

• Can't find an official Suzuki website with the info.
• https://www.gov.uk/check-vehicle-e10-petrol this is good info. you can directly put in your make/model and check compatibility.

I also have late 80's yamahas which fall into the non compatibility category.

Has anyone experimented with suitable additives?

That is a huge expense to get the dilution to 5% (which still contains ethanol, just less of it). Water is a lot cheaper, or free. The only expense is that when you extract all the ethanol from your fuel with water you will be 10% down on volume. It makes sense to do it before filling the tank prior to storage in the winter if you not going to use the bike regularly.

Yes. It is ieasy to exctract the ethanol from the mix. You only need a container and clean water. The trickiest bit would be to modify the container for easy separation / drainage of ethanol mix.

Put petrol into a container, add about 10% of clean water, shake, leave the mixture for a few hours. The ethanol (with water) will separate and will settle at the bottom of the container and once the purified petrol above is clear and not cloudy, collect it from the top or drain the water from the bottom of the container.

So will that additive do the job or what?

What is the fuel octane rating before ethanol is added?

Well, I am not sure about that. I think we had 95 octane fuel before ethanol additive was the new norm. I don't think the octane rating would be lowered before ethanol added, so the mixture is 95 octane.

Ethanol is the alcohol we all know about. Remove any remaining impurities and flavour to taste?

What is the actual damage 10% ethanol is supposed to do? Eats diaphragms, seals etc? Or just hygroscopic in a tank?

E85 is around 20% cheaper here in Sweden, I haven't tried the 636 on it yet.

This are in Lidl at the moment.

If I think I wont be using a bike for a while I'll be draining the tank.

It will suck petrol.

Why wouldn't it?

It is an option and if it was only one or two bikes yeah why not.

But what I have it's it's probably easier to drain them.

Hahaha mighty craic so.

Definitely doing it now.

I have one that pumps by hand but it's not great at getting fuel out of tanks.

What can go wrong?

Well I suppose petrol wouldn't be great for any seals inside.

I'll have to open it up and have a look and try a workaround if I think it needs it.

Most bikes have pumps submerged in fuel that can fail anyway.

I had a pump fail and when I took it out,a wire had a nick out of its insulation.

I'd probably be more worried about a vehicle that somebody uses one of these pumps all the time to drain the oil instead of via the sump plug.

I'm doing work on someone's bike at the moment and the sump had to come off.

37 year old bike, look what amassed.

The octane measure they use in the US isn't comparable with ours (look up RON and MON if you're interested) so the octane difference is much more slight than it looks.

Never used any but I ride year round.
