Has anyone had confirmed E10 woes?

[SirFallalot]

Was having the usual discussion with a friend about "how it leads to problems on older bikes as materials get corroded/worn/generally fecked" vs "E10s always existed, always put it into my non compatible bike, it still runs great and will forever".

Has anyone had any Confirmed "E10 ate my hamster" problems?

I've used it a couple times where E5 was unavailable, don't remember noticing a diff except it was cheaper I use it because Kawasaki advises to, but would rather pay less

Had the needle valves on a 1996 KLE500 fur up to the point they stuck open, flooded the airbox and set the bike on fire while I was riding it (thankfully self-extinguished).

I'm blaming E5 in fairness, it was the classic damage that kind of thing causes and the carbs had been cleaned out about 3 months previously when there was no sign of any corrosion in that area. Replaced the valves with ethanol compliant ones.

I’ve been running E10 in my ‘99 ZX6R, which was fine until there was a slight chill in the air, then it had some starting problems. In fairness it’s overdue for a valve clearances check so it could be that. I’ve taken it off the road with the intention of doing the job, but I did wonder what the starting qualities of E10 are like. There’s some speculation on the internet that it might affect cold-starting, but little hard evidence.

Canada had had E10 for years, It seems to gum up carbs with corrosion a lot faster when they are left sitting with the E10 fuel in them for a few months. The worst is always the small engines such as my pressure washer with a small carb with tiny orfices.

I either make sure l add a fuel stabilizer additive and/or fill up with premium fuel that has no ethanol.

I've used a couple of tankfuls, it seems to give about 10% lower mpg but as always it's hard to be directly compare.
That's not going to reduce emissions much.

E10? E5 is bad enough because where i live it`s all E5 now.

As posted before i had to chuck all my "suitable for unleaded fuel" pipes because they go slimy inside with E5.

I have also noticed that when leaving E5 fuel overnight in a container (pot noodle cup) it has water in the bottom through absorbing moisture.

Also carbs will not varnish up as years ago they will go rusty.

I've had the FI light come on randomly when turning on the ignition from cold that coincided with first tank of E10. It's only happened a couple of times but timing of it was a bit weird. Not actually been arsed to lift the seat and put it into dealer mode as ignition off/on has sorted it.

As I mostly work from home now I've only just done my first full tank of E10 and noticed absolutely nothing. Modern EFI bike though.

No problems using it here, but I feel that any issues are likely to be medium-long term so people are unlikely to be reporting them yet.

There is concern in some quarters over the likelihood that E10 will absorb significant amounts of water if left for longish periods, which is clearly a Bad Thing in fuel tanks etc. I've just taken the precaution of filling up with premium petrol this month, as my miles ridden per month falls off a cliff during the winter months.

I'm grateful for the fact that I'm in one of the E10 exempt areas of the UK.

If we ever got it here, I'm not sure any of the petrol stations would have the capacity to run an E5 pump or two and that would be a headache for a lot of people running small engines let alone the vintage crowd.

[blurredman]

No confirmation of anything in that regard for me yet.

But using on all my bikes (signature), and my 1980 Buick LeSabre, and my '91 Peugeot 205 1.1l (carb).


No problems regarding running at least.

You would think that keeping the tank full would minimis the amount of air in contact - advisable anyway to avoid condensation.
Obviously the tank isn't 100% airtight but not much exchanging going on.

Shortly after switching to E10 my 2019 CRF250L had a little trouble starting after a two week layup. Not too bad but it cut out when I throttled up leaving my street, then kangarooed a bit after restart. Quickly cleared. No issues since but it's been in more regular use since then.
