thanks for fast reply.
can't take car out at min cause it is raining heavy, but had it out yesterday and i seemed to use a lot more fuel than my brother but like u said he's is a different model, yesterday i really noticed an oily mist all over the back and spoiler of the car like it was lightly coated in oil. also once it first starts it firstly revs then dies down but does this very quickly . also sounds quite load when at idol.
