Seriously!...

I'd only get 100 miles odd from £20 worth of Optimax, now I'm getting 150/160 miles!... I haven't changed my driving style at all. I drive the car nice and smoothly with the odd blast now and again.

I'm well pleased!

Hope your ECU hasn't Reset during recent Mods Mark.

Causes car to run lean.
