I've got a MY99 UK Turbo. What fuel should I be using, UL or SUL?? Does it really matter?? :confused:

yes it does if you care about your engine!

optimax or SUL at all times ;)

i gained 2 mpg when i changed from 95 to 97. So i do actually save money. Do it!

I have a MY99 turbo and mix it up between Optimax most of the time and SUL now and again. I kept a record of MPG before and after changing from NUL to Optimax/SUL and also have noticed a better MPG since changing as well as smoother running - not sure about better performance though(might just be 'thinking' it's faster because it's got better fuel in) :)
