Hello all,

I'm sure this is a well trodden path, but I haven't been able to turn up anything concrete. Before I commit to buying a car I would be keen to know what engines can and cannot use unleaded fuel. I have been looking at new (and newish) 4/4s, so no problem there, and I guess anything with a Zetec uses unleaded, but there are a couple of early 1990s Plus 4s that have caught my eye, with both the M and T series Rover engines. Can these use unleaded? And what about the earlier CVH?

thanks in advance

Mark
