I've been away so just playing catch-up, so a bit surprised you haven't already had more (different) answers than there are active members.
If you don't have a favourite brand,, any reputable one, anything between 10/30 & 15/40, depending on price, availability, engine mileage &/or ambient temperature. Shell Rotella diesel has found great favour for old flat tappet engines such as ours but even that has its detractors.
Much the same story with filters, any reputable brand, although the general consensus seems to be Wix are good, Fram not so much & everything else falls in between. Not sure what you mean by "metric filter" I thought all XJ's were metricbut as they didn't arrive here until '94/5 I have little knowledge of early models & =, certainly, no idea of if/when they switched. Just get the one listed for your model.
