Hey all.I have a 2004 BA XR6T and my normal fuel economy used to sit around the 14L/100k,s.Since a I have towed my boat for the first time(1500kg)it is now reading 25L/100k,s and now maintains that figure with out towing.It this a sign of a shagged out cat?It also runs a little rough on a cold start aswell.Power seems to be fine.

Any ideas are welcome.

Thanks Darren....

Yah, me too. Did a run down south on the weekend, and is only slowly creeping up again.

Are you chugging through fuel, or is it just the reading that's worrying you?
