Engine oil filter for my 1996 XJ6 Vanden Plus
I've got about 184,000 km on this car. The oil looks relatively clean and it has a new looking oil filter. My question is, how do I tell if the oil is synthetic? It has a "Parts Master" oil filter. Is this any good?
What oil filter do you guys use for your 4.0 litre inline 6?

Welcome to the forum, Anbran. I stock whatever looks like the best deal on RockAuto. Lately that's been Motorcraft, although I have also used Bosch, as well as some other, lesser known and unremembered brands.
Short of sending a sample off for analysis, I don't know how you could distinguish whether or not your crankcase is housing synthetic oil or not. I further don't know why you'd care?
An excellent practice, if you've just acquired a 20+ year old car, would be to renew all the fluids so as to establish a baseline, unless you have documented maintenance history. FWIW, the 4.0L, as well as several Jaguar Techs, seem to like 15w-40 (5w-40 in syn) though you will find opinions on oil and oil filters are nearly as plentiful as rectal sphincters in any population of forum participants.
All but the hard-boiled brand ambassadors will agree that new, clean oil, changed at the recommended intervals, will result in a long-lived AJ-16 irrespective of brand and viscosity rating within reasonable parameters.

At the risk of poking a stick into a hornets nest, my only input re viscosity is to pay attention to the Jaguar recommendations for your climate. There is sometimes a temptation to put “thicker” oil in because the engine is “old” and will be worn. In fact a well maintained AJ16 will evidence very little wear, and these engines were designed to run on relatively “ thin” modern oil.

Hi Anbran,
Welcome to the Jaguar Forums! It's great to have you with us!
Ditto on countyjag's advice to follow Jaguar's oil specifications. Your car was manufactured a decade before Jaguar began specifying synthetic oil, so you can use conventional oil (which I personally prefer in the AJ16, but I don't judge those who want to use synthetic).
Rock Auto usually carries the Mann W7197 and Mahle OC238 oil filters. Mann and Mahle are long-term original equipment manufacturers (OEMs) for Jaguar. The Mann is the same filter you will get at a Jaguar dealership without the Jaguar graphics. I usually order 2 or 3 Manns at a time to reduce the per-filter cost of shipping.
The Wix 51231 is also excellent and Wix is now owned by Mann+Hummel.
Two very important features you want in an oil filter are a check valve or non-return valve, which helps keep the oil system primed, and a bypass valve, which allows oil to flow should the filter become obstructed. The Mann, Mahle and Wix all have these features.
Cheers,
Don
