I run it on my car, but at a 50/50 mix or 75/25 mix. I have to flick a switch or 2 over to go between fuel maps. I get it from Morrisons in Crowborough . They price it at 5/6 pence less than the 95 ron unleaded.
It works But you'll need the right fuel pumps, lines, injectors, fuel rail , tune/tuner , fuel pressure etc etc. So unless you can get it regularly and easily/cheaply don't bother, go and get your car tuned on bp 102 or race fuel.
I tested this out at North weald the other week and managed a 132 ET on the 1/4 mile on my stock block so I'm quite happy with it for now.
The result is more power, lower Egt's, is much cleaner and I believe, would pass an emissions test without catalytic converters installed. The other down side is a drop in fuel consumption
