I use bp ultimate or vortex but useually go for the bp first, why would you own a high performance bike and use cheap fuel.
Try to stay away from dodgey servos they make good hamburgers useually though.
Have read plenty about tolulene you can buy a 20 litre drum of the stuff for the same price as a 500ml bottle of the same stuff with octane booster written on the front.
If you are worried about it dont sniff it, also suposed to be a great solvent for cleaning fuel injectors....just stick to the bp and stay away from dodgy servos unless you need a hamburger.
