Hi guys I'm in the Uk and drive my XJ-S daily throughout the seasons. Going for an oil change next week, what oil should I use? 3.6 Manual XJ-S with 72,000 miles. Oil type and Brand would be good please. Should I use specific oil filter too?

Thanks

 

I like to make my own out of beeswax and mineral oil, its super slippery on the garage floor. Thats how I know it good. Or you can use Castrol GTX 20/50 if you prefer to use commercial stuff.

 

100% synthetic 5w 30 or 10w 30, regardless of make as long as it is a well known make.

 

Hi Duke,

When I first bought my 1990, 3.6, manual I had it serviced by a long time Jag expert who recommended Shell Helix 10-40 semi synthetic. I changed the engine oil myself a few months ago (due to lockdown) and got some mail order from one of the motor mail order specialists in the UK. You will need two gallon cans.

The sump plug is big (30mm???) so check you have the correct size before jacking the car up.

I can't remember the exact engine oil capacity but it is more than most (7 or 8 liters from memory) so you need a big container to catch the old oil. I got a plastic one off of Amazon with a pouring spout for not a lot of money.

Cheers,
LeeP

 

Just noticed you have a 3.6. Nevermind

 

Castrol Magnatec 10w40 semi-synthetic, Look around for prices as they vary massively. Oil filter from Jaguar.

Good luck

Paul

 

What ever is on sale. 10L plus added up quickly lol. I've used pensoil and Castrol regular so far 10w40.

When I get it on the road in a couple more years I'll switch to royal purple.

 

The owners manual will tell you the recommended viscosity for the ambient conditions. However, with modern oils, use the lowest first number you can find. So if the recommended oil is 10W40, use a 0W40.

The reason is the first number describes the cold viscosity, and a lower number means the oil will be more pumpable and get up into the engine faster after startup. 90% of engine wear occurs on startup, so that is the need for oil to get things lubricated quickly after start. The second number is the hot viscosity, match that to whatever the engine maker calls for.

 

I always suggest, CLEAN,

Followed by 10W40, Semi or Full Synthetic.

Whatever is on special works also for me on these "older Technology" engines.

Filters, Ryco (Big$$), Geniuine (if push comes to shove, but $$ are usually OK), MAXX, Cooper. Again, whatever is IN STOCK, at the time I want it, and down here that can be a PITA.

 

Where I am, I can buy a genuine filter at the dealer cheaper than a Fram. That's a no contest in my eyes.

That being said, I have used Ford Motorcraft filters for a while and they are high quality. I can get the Motorcraft FL2021 for under $7, so I have used them.

 

Yep, The OE here for the 6 and 12 were AU$12 a while back.

Since the last engines to use that one are now 23 years old, youngest, and demand is down, they are dearer.

Ryco, last I looked, was $45.

MAXX, were $17

Cooper, been too long, so not accurate at all.

The later fleet beasts all run MAXX, and $12.5 is OK for something I will throw away twice a year.

Last one I got for the MK VII, cartridge style, was $40, but I suppose 1954 vehicles, ya gotta pay.

 

Not quite! Rolls Royce used the same filter up to 2002, Bentley to 2010. The later Jaguar V8 filters can also be used on the earlier V12 and 6. The filter OD is smaller, but the thread and gasket size is the same.

 

V12/6 filter vs the V8 filter:

 

For the 1000th time...


BUY OIL FROM YOUR LOCAL SEMI TRUCK DEALER it'll be half the price of retail. I get 3.8L jugs of Chevron Delo synth 10w40 with advanced soot control for $16/cad ...better than 25-30+ at walmart for junk.

And USE OIL ADDITIVES I am a vocal advocate for LiquiMoly products like CeraTec, and Archoil etc reduced wear lower engine temps faster rev and less throttle effort (less mechanical resistance) I've had members msg me with results nanoceramic friction modifiers WORK.
