Can you use E10 - web-based checker:

[BBROWN1664]

based on the 10% blend vs the 5% blend, you would loose about 2% of the overall power from the engine based on the calorific value of the fuel. 99.99999% of people would never even notice that.

E10 was introduced in France quite a few years ago, and I had reservations regarding a recent trip to France and Spain, regarding E5 availability.I only came across one petrol station that offered only E10, with the majority offering E5 98 octane alongside E10, and some had both E5 95 and 98 along with E10. Hopefully the UK will follow suit regarding long term E5 availability.

Not in Teesside, north wales, Scotland, Dorset or north west England I believe, they will have ethanol in their super but only up to 5%

That info was only regarding Esso Synergy Supreme+ which is totally ethanol free other than Devon,Cornwall,Teeside, NW England and Scotland where it will contain 5%, which will no doubt be the standard for all petrol stations super grade other than Esso. I make Esso stations my first choice in my usual riding area Surrey,Kent,Hampshire,Essex etc as know I'll be getting the good stuff. :thumbup

I'll throw this into the debate. I've had the Fazer now for 8 years, I had a PC5 fitted and set up on a dyno to maximise performance, Scorpion system and decat link pipe. I still found (a common problem I believe) that when closing the throttle from wide open, then opening it up again, the response time was not immediate, possibly more noticeable to me as I do several trackdays a year on the Fazer. However, the last time I filled up, I sought out and used BP Ultimate. Although I have not changed anything else on the bike, the problem has 95% disappeared, and now picks up smoothly from closed.

The ECU cuts the fuel on the overrun and it takes a while to build up fuel pressure again when you apply the throttle this causes the lag you describe, akin to turbo lag in years gone by. There is a Fuel Cut Eliminator available from Ivans Performance in the states which sorts it
