The recommended oil viscosity for your climate is listed in the manual. There's no need to second guess or experiment.
As for type and brand, it's not much different than asking 'what's the best beer?' Everybody has got a strong opinion and everybody else's is wrong.
Be aware that you might feel strongly about certain preferences but the car couldn't care less.

HEY, I've got a 1999 xk8, 4.0 and have been getting my oil & filter changed at a lube shop here where I live and they put 10w-40 Pennzoil FULL synthetic. if I'm not mistaken, the upside with synthetic lubricants is that they leave a film of lubricant on all internal moving parts and that gives you protection when you first start the engine the next time. cold starts are where the most wear occurs. I believe mineral oils don't offer that.
others in here may or may not agree with that. btw, they charge me $72 for the change.

Use them if you like but there will be no real world benefits.

mikey, many people use synthetic lubricants for a variety of reasons. they burn cleaner, resist deterioration better and most will leave a light film of lubricant on all the internal moving parts and therefore retarding the wear upon a cold start. many report getting better fuel economy due to the reduction of friction and slightly cooler running engines. I am aware that most engines are designed with a specific operating temperature for optimum performance and i'm not aware of any synthetics causing one to run 'cooler' than the correct operating temperature for a particular engine.
having said all that, mineral oils still provide excellent service and of course are less expensive.
happy motoring,

There's actually very little real-world data to back it up. Engine failures due to lubrication are a thing of the distant past, irrespective of what type of oil is used.
Again, owners should choose an oil that meets the OEM spec. Going beyond that will not help the car.

I am kind of old fashioned...DUH I use a 5W30 in the cold(45 to -20 degrees), and 20w50, when it is warm(50 to 110 degrees) I always use a thicker oil, in high mileage engines(over 80,000 miles), and a very good oil filter with a one way valve in it.(not Fram) I also change my oil every 3000 miles. After 4 or 5 oil changes, the oil comes out looking like new, and I like it that way. I know synthetic oil can last a long time, but the chief reason to change the oil is to remove the chemical contaminants, that like eating aluminium and brass. I change my antifreeze frequently also, after having to have a machine shop drill out broken studs, that were eaten away by old coolant....Be cool.....Mike

A little something to read - Bob is the Oil Guy - Bob is the Oil Guy
I personally am not in favor of going higher than 10w-30 but that is my preference.
I recently removed my valve cover to inspect the tensioners and I am attaching a photo of that.

That would be the 40 part. And since you don't see freezing weather,
a 15W40 would suit you fine year round.
Walmart sells 15w40 Shell Rotella conventional.
They should also have 0W40 Shell Rotella T6 synthetic.
Forget if Castrol has a 0W40 synthetic.
If you find a Castrol in the 5W30 black bottle synthetic that
says "Made in Belgium" on the back, it is the fabled GC(German Castrol)
that all the oil people rave about. It is a "thick" thirty, and meets the
demanding ACEA A3/B4 European spec as well as various BMW/VW
specs which are again demanding.
BTW, you can take comfort from the fact that Jaguar Warranty coverage
in Mexico for those years required xW40 oil. That may give you some
idea of what Jaguar thought about using a xW40 in hotter climates.
Notice the weasel words in the manual right after the 5W30 recommendation
at the top ... "for best fuel economy". Their concern, which is not your concern,
was meeting CAFE requirements. For most people who have a basic level of
understanding of the English language, "for best fuel economy" is not the
same as "for best engine protection". Read between the lines.

why so complicated ... oil seems to be a quite difficult theme ...
the manual says 5W30 ... point
So use what the manual says ... buy Mobil1 or Shell
Using new kind of oils isnīt so clever because you have to notice, that the engine is developed quite a few years ago. Jaguar knows, whats best for the XKs.
