Bioethanol news item - 'ideal for turbos'
BBC has an article about the increasing use of bioethanol in fuel:
http://news.bbc.co.uk/1/hi/business/4498934.stm
It doesn't mention that the Tesco 99 octane is up to 5% bioethanol (post corrected), but it quotes Saab:
'E85's higher octane rating adds 30bhp to the 150bhp turbocharged engine, and a 15% gain in fuel consumption can be had at high speeds, said Kjell ac Bergstrom, chief executive, of Saab Automobile Powertrain.
"Turbocharged engines are particularly well suited to the benefits of ethanol," Mr Bergstrom says.'
Now the bad news - there are some issues with the effect of E85 (the 85% bio version) on Scoobs:

I thought that Tesco 99 Ron was about 5% bioethanol http://www.greenergy.com/products/99_octane.html - that bit from the Australian website is a bit worrying especially as minis is a UK MY99 with a few added tweaks, it does seem to like Tesco 99 at the moment though.

My MY05STI PPP loves Tesco 99. starts better, pulls better and runs smoother. I will ring Subaru UK just to check. BP Ultimate sucks in my car, ran like someone had stuf a rag in the turbo and had problems starting in the cold mornings and ran rough low down too.

Because E85 has a much higher octane rating (104 RON) than petrol, this allows the timing of the engine's ignition to be advanced, producing more power without risk of harmful 'knocking'.
