There is a lot of scaremongering going on and panic buying it seems, like when the supermarkets got emptied on Loo rolls when the virus started....it wasn't that kind of virus!
Not that I'm saying the E10, or indeed the E5 situation isn't a disaster for our older classics.
Now, not all superunleaded fuels are ethanol free....I did some digging on it a hwile back, think it's just Esso that are E free... just that the superunleaded fuels still have an E5 limit.
This I would suggest to all our guys and galls on here is still very much to be avoided without making extra precautions.
A little precautionary tale.
A couple of weeks ago, the Bank holiday weekend, I woke up theintegrale from the unit planning on going to cadwell for the afternoon. On moving the car out then turning around to close the workshop doors I saw a trail of fluid, directly in line from where the car was and the route I'd taken. The fact it was fuel and leaking in the engine bay soon had me abandon any thoughts of a nice ride out!
The new rubber fuel lines I'd fitted 2 or so years ago were badly cracked under the coolant reservoir out of sight. I have always used superunleaded in the car but that still hasn't prevented this issue. Obviously fuel leaking onto the exhaust front pipe isn't ideal, so it has sat motionless until I find a better solution.
Tonight I have ordered enough new pipe (4M) to do the integrale and the Dedra as it too has an engine bay fuel leak, not cheap at around £85 inc some new stainless clips but way cheaper than a fireball. This stuff is said to be E15 resistant and the best spec currently available, I would suggest to anyone else to change before the splits become serious!

An alternative is an Ethanol stabilisor, which also has the added benefit of lead additive to combat valve seat errosion. A faff maybe and an extra cost, but £12 for enough to treat 250L is about the same as using superunleaded assuming a 5p p/l difference, which it is probably way more than that anyway!
