i believe the early engines were run on leaded fuel but they have got hardend valve seats so they can run on unleaded with no problem

I disagree, unless you know this for a fact?

The lead will damage the 4x4 cat.

The 2WD's were leaded but can also run on unleaded, this is why they had red cam covers and 4x4 had a green cam cover, denoting the respective fuels.

YBJ has no car as you say, but YBG has cat, so I doubt this can run on leaded

The YBG was not the later model of the YBJ. The YBG was sold in regions where a cat engine was needed, the YBJ was sold where it was not needed. Holland never got the YBJ, only the YBG. YBJ cars have later been imported from for instance Italy, where the cat was not needed.

What interests me is that the manual on my standard 4wd (red top) states to use unleaded fuel, yet all of the threads, tuners, rsoc etc etc say it MUST me 98 RON or it'll blow up

Why can't i just run ordinary 95 unleaded if that's what the Ford book says?

Is yours standard though , if so then as the manual states.

I run mine on 95, it depends on what it's mapped for, I assume by the advise they have given you that it's "Mapped" for SUL?

SUL is recommended for performance cars though.

Then you can run it as the manual says imo, RSOC etc don't know more than Ford

The only thing I think they could mean is four star was 97 octane, and SUL is 98, so if your car is totally standard then it may be more suitable, as technically your supposed to make ignition timing adjustments for unleaded petrol.

I've had my 3dr since 1990, and I used to run it on 4 star until it was phased out. Since then I've run it on premium unleaded with no probs at all

They have hardened valve seats so can run unleaded no problems, although as is common practice it's wise to adjust the ignition timing if changing the fuel.

It will if it's mapped for it I think the problem is if it's mapped for SUL and you run it on unleaded.
