Running unleaded fuel at the moment and the car feels as though it is holding back above 4000rpm.Would I be better running it on super unleaded.

 

Please use a proper fuel dude optimax (dunno if they do it near u but check out da shell site i suppose) is my gas of choice & i'm about 2 start sticking octane booster in that so i dread 2 think wot it's like with the shyte it sounds like u use.
Presuming it is a scoob u have then u surely cant b so skint as 2 starve yer baby of tasty food (fuel)?
U no u wana

Cheers scooby si thats what i was wanting to hear.
