Why not use the Nulon oil which has ZF approval, unlike all the others?

Suitable, not approved. Sorry for being pedantic, but big difference in whose ass is on the line if something goes wrong.

That rev hunt your talking (if I understood what you said correctly) is just the car running the rich startup cause its cold.

Wrong.

The box is actually commanding the PCM to do that.

Why would it do that though, any ideas?

I read another member who had the same problem, monsta torque suggested it had previously had water contamination and the torque converter may be damaged. Ford checked for fault codes and it only said clutch slip.

Water contamination does cause hunting too, riptide had it, his was all the time though

It could be a number of things like converter is trying to lock up early or incorrect oil temp reading. It's not easy to diagnose over the net.

Fair point. I assumed the title of the other thread was correct.

I used the genuine oil for my service and will continue to do so. Not worth the risk not to IMO.

So what is the reasoning for the PCM doing it?

I know that run a rich cycle on start for a little bit which also shows in the revs, whats the PCM one about.

The rich cycle is open loop and it bypasses the o2 sensor and runs a different fuel map. Since its a static map, revvs shouldn't hunt. Not sure if our map sensor and coolant temp is used to calculate AFR in this case but if they are the. Maybe one of those is faulty.
