I have gone off ethanol
I actually found i got BETTER economy and performance.
I stopped because the Federal Chamber of Automotive Industries
http://www.fcai.com.au/ethanol
says the extra oxygenation of fuel is not good for steel lines and rubber hoses
Ethanol is rated at 94 Octane - so no good for my Mk4 Golf either. Min 95
VW doesnt recommend it for their cars.
Dear Barry,
Thank you for your enquiry,
For the latest model cars, ie the millenium versions, it is best to use a
98 octane fuel with no more than 10% ethanol. For your VW Golf, a 95 octane is suitable but you would need to confirm if the E10 is definitely 91 octane.
E10 would not be suitable for any of your vehicles, however to use this fuel would be your perogative. Volkswagen vehicles are designed to use certain octanes.
Ethanol blends are only new on the market and not a lot of research on the long term effects have been made yet for the Volkswagen brand. Please always stay with What is recommended for your particular vehicle. Please contact a Volkswagen trained Technician to seek some more advice with particular fuel blends.

Caltex's replies to my questions
Barry,
Caltex E10 must meet the Australian Standard for regular Unleaded petrol, which has an Octane rating of 91 minimum, however, when you add 10%volume Ethanol to regular Unleaded petrol, the Octane of the mixture finishes up at between 94 - 95. Caltex Vortex has a guaranteed Octane rating of 95 minimum, so this is the one you should use. If you require a 98 Octane in the future, we do market Caltex Vortex 98 ( which is 98 Octane), but it is currently only available in Sydney and Brisbane areas.
As for suitability of use for E10, our information on VWs is that it is suitable for all VWs from 1986 onwards, unless the vehicle has a carburettor, and , of course, providing the vehicle does not require a minimum Octane fuel of 95 or more.
