I noticed, when using a Sainsburys filling station, that E10 fuel will soon be replacing E5.

Seems that not all petrol fuelled vehicles are fully compatible with E10.

I thought it generally already had.

Phil for your older bikes Ive read theyre using super unleaded which will still only have 5% ethanol for now.

Also drain petrol out of carb when not using it for long time.

I read somewhere that owners of petrol powered lawn mowers and similar should check combatibility with E10.
I hadn't noticed until reading about it that our local Asda petrol station were already supplying E10.

Esso supreme+ 99 is Ethanol free in most areas I believe if needed.

Filled up with my first tankful of E10 on Thursday, it's already here in Pompey. Got me to South Yorkshire and back, couldn't tell any difference in performance or economy. 2014 Lexus IS300h.

From what little I have read about E10 (mainly in USA) it's the long term effects that may be a problem.

The only thing I'm likely to use E10 in is my Hyundai 200cc lawnmower.

It’s really only an issue for classic car and bike owners, corrosion, degrading of rubber hoses and seals etc. Stick to the Super unleaded as Nick said ‘up to 5%’ ethanol and the Esso Super as it’s ethanol free in some regions. E10 has a lower calorific value and contains more oxygen so a jet size increase may be advisable on your classic along with a few degrees more ignition advance. Use a fuel stabiliser for over winter storage of fuel in the car with at least a 90% full tank.

Thanks Neal, that's a thing I didn't know about. I guess you mean this sort of thing?

Yes that’s the sort of stuff. There’s some debate over the effectiveness of these additives but I’ve been happy with STA-BIL and have bought some Classic Valvemaster Plus to try even though it’s intended as a lead replacements it says it stabilises E5/10 fuel…

Gov website to check if your vehicle is E10 compatible.

For Nick.

Porsche
E10 petrol is cleared for use in Porsche vehicles with petrol engines since the 1998 model year and all Boxster models with petrol engines since the 1997 model year.

The Carrera GT is not cleared for use with E10 petrol.

Thanks Phil, I guess, I did check a month or so ago, but I use Esso Supreme+99 most of the time anyway. Will use that in the bike as well as I think that’s more likely to have problems given its from 1976.

Not "proof" about E fuel stabilisers but interesting.

yeah seen that before hardly a controlled environment though. More research is required I think…
