It's your posts on the topic here and on another MG Rover related forum that put my mind at ease on this topic.

The fact you have run your K-series engines on E85 fuel for years with no negative side effects just reinforces the fact that nobody has anything to worry about.

More than that.
As I'm not myself a petrolhead and might be seen as a non reliable authority despite my experience, I can tell you that I've just done last July a remap. Don't laugh! The aim was just to get a better torque in the low revs and uprate a little the bhp eventually.

Then I went to a very reliable garage I had been pointed to by my local vintage car club president & secretary: "LR Performance" which is the only local technical team allowed to intervene on the Albi race circuit (together with the racing teams of course). BTW they are specialized as well to help any compliant engine to be fuelled with E85.

When I told them my KV6 was already E85 compliant and that I'd already done the job myself (by a different way than theirs indeed!), I saw that the technician wasn't very keen. Then he told me they had to comprehensively verify my engine and my car before anything else, which they did. In the end he came back to tell me that my car was in very good nick for its age (1999) & mileage (191k km / 120k mls), and that they accepted to do the remap I'd asked for. Only then! You know they don't want to be involved in a damaging or destroying process... With a very good result: 80% of the max torque since 2k revs and +7 bhp: blissful!

Hence I think it's a good evidence made by a well known French professional garage in its area that a KV6 Rover / MG can even be higher ethanol blend fuels compliant without any damage.
I hope all that may definitely help lots of mates in Britain to feel safer & relaxed about E10 in the future for their pride & joy.
The rest is only gossips & scaremongery IMHO...
