Well we do have borrowers, so maybe they are getting a little more extreme.

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

The ethanol was added instead of tetra-ethyl lead (so essentially to unleaded petrol) but performed partly the same function (ie as an anti-knock agent).

I see the article mentions Millers "fuel storage treatment and corrosion inhibitor"
is there any evidence that this stuff works? :

Just as a (rather flawed) experiment I've put some Amal brass jets and Mazak parts into a jam jar half full of ordinary petrol (I assume 5%) and will leave it over the winter to observe results.

I will report back in the spring.

Not just petrol tanks keep a check on fuel lines replaced them every 3-4 yrs they get eaten from within , not only leaking but causing issues in the carbs even with fuel filters fitted yes they are supposed to be Ethanol proof. That said never had issues starting even with 3 mth + fuel sat sitting I read in one of the classic mags to use REDEX helps keep the fuel longer? They implied it helped stabilise unleaded fuel, not used the premium fuels DO add redex seems to work ......

As yet I've not experienced any ethanol related problems with my Guzzis maybe because I use the "super" varieties of petrol. But none the less I found this article very interesting and informative.

Only got around to reading  this   , interesting indeed , While My B750 has a slightly elongated petrol tank  my '93 MZ  with what i think is an Acerbis manufactured 21 odd litre plastic tank has been ok up till now.
The description of the jelly found in carbs reminded me of an F650 Bmw  that I  recommissioned for a friend after a longish lay off

I got to the stage of draining the carbs (i.e. float bowls off and tipped out) if bike was going to be left for any length of time. Never needed to do that 10+ years ago.

Result of leaving petrol in Monza carbs for long time, note the idle jet is rotted away bottom right of float bowl, both carbs in same state. Possibly the worst I`ve ever had to deal with and I assume it`s all down to the dreaded Ethanol
