Most of the fuel additives are only there to stabilise the Ethanol in the petrol. Don't let the Ethanol get in there in the first place (see this thread http://www.sohc.co.uk/index.php/topic,8911.0.html), job done the fuel will survive more than a winter without issues. Just run it up until its fully hot once a month if your not using it. The Ethanol can evaporate rapidly causing crud and it absorbs water from the atmosphere which causes your tank to rot. If left long enough in a damp garage it can absorb enough water to separate out and be just water at the bottom of the tank. Mega rot and mess. Cant stress enough, please guys keep the Ethanol out of your bikes, they will also run better without it. BP Ultimate Super Unleaded (except in the South West).
Your spot on there Mark. Looking at advice from research, removing the Ethanol from E5 should lower the octane by one and E10 by two. So if you start with super unleaded it should be good for classics. Does anyone know the chemistry of how this eBay device works? If its genuine, £50 is better than a new tank. And 18lts at a go is a useful amount as long as it only takes overnight. Doesn't help on a journey over 200 miles though. But those are pretty rare except for the annual trip to the Isle of Man, but their petrol is Ethanol free anyway.
Found this http://www.mcnews.com/mcn/technical/2012decethanol.pdf very interesting reading. Think I may give it a go to see if I can find some pump fuel ie. "BP Ultimate" that really is Ethanol free. This will show it up nicely, so have taken the plunge and ordered a kit. Will report back when the kit arrives and I have time to test it. If it works well it's worth every penny of £50. If "BP Ultimate" does turn out to contain Ethanol, the kit will get a fair bit of use making all the petrol I use Ethanol free. What price peace of mind?
