I'm only reporting my own and others' experiences. No need to be sarcastic.

Older riders may remember Cleveland Discol which was widely on sale for many years in the 1950s and contained 10% - 20% ethanol (supplied by Distillers Company).


I am unaware of any problems caused by this and would welcome any evidence.

I'm not saying there aren't problems experienced by people; what I am suggesting is that modern petrol is packed with substances like benzene (a known carcinogenic) which to my mind are more likely to be causing problems.

For what it's worth I use ordinary pump petrol in my bikes (except the V50 which specifies 97 octane). I've left many bikes unused for months without draining tank or carb(s) and they've started first kick. I've not experienced any of the issues described by others in any of my old or modern bikes.

Obviously I lead a charmed life and have done since I started riding over 50 years ago.

"I don't actually think it's ethanol."

Well Ian, did you say that or not, and what evidence did you provide to back it up with apart from problem you had years ago with a Triumph fuel tank you'd left laying around? That's not being sarcastic, it's putting your statement into context and backed up by you making further unsubstantiated claims about benzine causing the problem; unless you think that soft fuel tanks are a form of cancer?

Length of time doing something doesn't make anyone an expert. I've been riding on buses all my life and I still couldn't drive one.

I said "think". I still await real evidence that it's ethanol not something else.

But believe what you like.

I got the chance to drive a bus once. It seemed like a doddle until the back wheels started jumping as I took a bend too fast. It was one of those tanner to half crown moments Happy days...

So I did.

[QUOTE=BobV7] Hi Chris
There is problem with that, and that is many owners of newer machines have reported issues of poor running on premium grade fuel simply because the engines are not designed to use it. It's OK for the owners of older machine that will run on any old fuel but times have moved on a bit since they first trundled out of the factory.


Last time I tried premium in a V50/3 the down pipes started to glow resulting in having to faff around with the timing, however, easier solution was to tip the fuel into my 1150RT and revert back to 95. Strange thing is the V50s were originally made to run on 97 octane.

The Cleveland Discol brings back some memories but that was added to leaded fuel in those days so maybe that's the difference

I like coaches, specially the ones that come in long strings with a kettle up front. You used to be able to get a proper breakfast on them. Whatever happened to them?

But back in the 50s there weren't any pastic tanks.

Also I took the tank off the Norge (not full of petrol - too heavy) and put it back on again the following day, well tried to.
The tank has not distorted, it still fits apart from the fact that it is about 20mm longer thn it used to be. The fork top yoke now hits the tank and the rear bolt is way back from the theaded hole.

Better 5 minutes late in this world than years early in the next.

National Benzole added ethanol too. It usually needed the carburation altered. It was added as an anti-knock agent.
Ethanol may attack plastics but petrol itself is a pretty good solvent too.

When I had my Tiger 955i with a plastic tank it was well known that if you took the tank off when it was full of petrol and left it for any length of time the fittings wouldn't line up as the tank would distort. And that was early 2000s well before ethanol arrived.

I have a 955 Tiger and the tank has not expanded although I do try and leave as little petrol in it as possible if its not being used.However,before the Tiger I had a Sprint ST.The tank on that had expanded a fair bit making it very hard to refit.

Brian are you absolutely sure that someone isn't shortening the frame on the Norge whilst your back is turned, every time you take the tank off?
