Well as you may have read few weeks ago i was about to start using Optimax and wondered what other people thought.
After 3 full tanks it changed the nature of the car entirely.
Firstly, Performance - Its bloody loads better

. Pulls a lot harder in 2nd and 5th. Also it is a lot lot smoother. Dont get the resonance at 60 mph like i did before. Quicker to warm up, quieter and just generally a lot nicer to drive.
Secondly, MPG. Up about 2mpg on the tank. Takes a while longer to get a decent MPG reading but when it gets going its a lot better (but i reckon this is just the weather).
Cant recommend this enough. Will never use anything but it now. Transformed the car and is simply a lot better to drive.
