Hi, I have a MK4 Vauxhall Astra Club 1.6 8V Y Reg.
On £20 of fuel at an average of £1.07p per litre petrol, its giving me about 80miles, or 100 motorway miles.
I'm getting really pissed now!
Ive just changed my exhaust (back and centre) doesnt do anything.
I've calculated its giving me about 20 MPG which is REALLY BAD! I might aswell be driving a VXR or something!
