Oil filter and oil

Best for the filter to buy from a reputable Jaguar supplier for a car as old as this. The engine is worth a lot more than trying to get by with cheap filters. OK, if the Fram filter fits, its probably OK, as filtration is far better than it ever was in 1954 !
However, for oil, I would avoid the modern "thin" oils. The XK engine was built on well-used machinery, (second-hand from Standard), to tolerances that were much wider than today. I would use a good brand of something like 20W50, or a 15W40. However, what condition is your engine in ? If it has had a fairly recent overhaul, you'll be pretty safe with a 15W40 as that is what was recommended for the XJ saloons using the same engine 30 years later !! I don't think anything changed in the production line, the machinery was just a lot older by then.

Someone has recommended this for classic cars even though it is a synthetic.
Will it work do you think?
AMSOIL Z-ROD® 20W-50 Synthetic Motor Oil

Check out Ratblog540 for more than you ever wanted to know on eng oil and oil filters. Very good empirical comparisons on a lot of different brands of oil and of the various oil characteristics with explanations as to why one is better than the other.
You can also as the blog questions and he will answer.
One of the top performing oils is Valvoline VR! mineral Oil. Silver bottle labeled Racing but with the characteristics you need for flat tappet street drivers. It's high ZDDP if you're into that.
Available in the US in 20w50 and 10w30. Summit Racing, Amazon, others including your local auto parts store carry it. Other geographic areas may have the 15w40 they make available as well.
Don't get confused in buying because they also make a VR1 Racing oil in a black bottle which is strictly racing oil, and a VR1 Synthetic.
Just to be clear, I have no affiliation with either RatBlog540 or Valvoline.
