Vs caprice grange spec
Hey guys my v6 caprice is using about 28 L to the 100 and is all black out out of the exhaust. It’ not showing any faults on the computer. It intermittently runs rough and blows black smoke. It has 345000 on it any thoughts

Possibly both exhaust sensors are stuffed and it is too rich. If only one goes, then you get error codes from left-right mismatch.

If it's using twice the amount of fuel it should I'd be getting the reg checked out. I've had two faulty O2 sensors over the time and only used an extra litre or two per 100km.

Yep I'd certainly agree with that.
