Agreed the Gov gave the ok to use Ethanol, to help reduce the price of fuel and yet this is more expensive. What Crap!
As most of you guys, if ur running stock ECU u will not notice much of a difference. If you just buy an aftermarket ECU and tune to this fuel, ur not acheiving much. Unless ur going to be doing some other big mods.
Personally l have turned off the shell optimax, l have found most of the time the alternatives from Caltex and BP have been cheaper.
