heh heh, pays to read the fine print i guess...
The bio-fuel in question is an ethanol blend...
This stuff is available here pretty cheaply... usually from the smaller fuel companies eg: SAFF and LIBERTY servos...
It's basically unleaded mixed with ethanol...
most commonly available stuff is E85, and Liberty sells E10, which is a 96RON ethanol blend. The E85, oddly enough has an RON (octane rating) of 85...
And before any of you think "hmm, 85RON, premium unleaded is 96 or 98 RON, E85 is $hit and wont make my car run well", try the stuff.
E85 is the new avgas... The performance capabilities of this fuel are very surprising. As the engine runs a lot cooler, like it does with avgas or methanol, you can run a heap more timing. Some of the numbers coming out of highly tuned engines, particularly those that have forced induction, are damned impressive.
The only downside with running E85 on these worked engines, particularly the ones that are designed and tuned to run only on E85, is that they chew through a heap of juice. Due to the timing that can be run with ethanol-blend fuels, they also need a heap of fuel to do it... Roughly 30% more than using premium... But you also gain a lot more horespower than the equivalent motor running on premium...
And yes, E85 will run well in pretty much everything... I've been running it in my twin-turbo aristo for a few weeks now, (was previously running only 98RON premium, occasionally with octane boost thrown in for good measure), and there is no noticeable powerloss running fuel with a much lower octane rating, and it runs cooler... Win!
oh and E85 is about 20c a litre cheaper than premium in most cases...
