Owners manual says to use Castrol SLX 5W-20 in my 2011 XKR. This is not available any more. So what do you use? Research from Jaguar says Castrol Edge 0W-20. Do you use this?

 

Your 2011 XKR is out of warranty so you can use any brand of oil that meets Jaguar's specifications - or not. Your car, your money, your choice.

See: Which oil?

No other topic has received more posts.

 

Edge 0-20 is fine.

 

The JLR recommendation has changed since your Owner's Handbook was printed. It is now:

Castrol EDGE Professional 0W-20 EC engine oil specification STJLR.03.5006, STJLR.51.5122 0W-20 lubricant.





If you are looking for an equivalent from another manufacturer, it's the STJLR reference and weight that counts.

Both my XK and F-PACE require the identical oil specification. Just a shame they take different size oil filters!

The latest oil specification, STJLR.51.5122, is discussed in the "Which oil?" link in my Post #2, above, beginning with thread #28. That spec oil is now available from several brands, including but not limited to Castrol, Ravenol, Liqui-Moly, and Mobil 1, at varying prices.

I would shop around for the lowest price oil that meets STJLR.51.5122 for my 5.0L. So long as it meets that spec, what difference does the brand make?

 

in the age of “branding”, marketing is king, lol.

 

Stuart S, Thanks for the info. Doing some looking I found the same thing.

 

Absolutely! Would you eat a Gooseberry? Or a Horse Mackerel? They don't sound very appetizing. 🤮

But change their names to Kiwifruit and Tuna fish, and the rest is history.

The bluefin was not always considered a delicacy. In the early 1900s the fish was known as “horse mackerel,” and its red, strong-flavored flesh was considered suitable fare only for dogs and cats. ..."

Just keep it British with Castrol; for Queen and Country.

Where can I buy? LOL

 

Many a fortune has been made in my state with whale oil. The Nye's are prominent family name in olde MA history.

 

I use Pennzoil Ultra Platinum genuine full synthetic (not fake full synthetic like most others) in either 0w20 or 5w20 depending on climate. It meets the JLR specification and according to prominent analysis likely exceeds the Castrol quality and even better, it's quite inexpensive.

 

jahammer isn't this thread about what oil to use in the 5L engine? Your sig lists a 2008 so 4.2 (right?) and that engine doesn't have the same oil requirements as the 5 L, does it..
So, respectfully, I'd say that your post sort of muddies the waters doesn't it?

 

The oils I referred to are NOT for the 4.2. I have other JLR vehicles as well which do use the same oils as all modern JLR models do.

 

 

Yep, old thread. I get that the 0-20 is intended for the 5.0. But for the 4.2, is it 0-20 or the original spec of 5-30? I live in Florida, so hot summer. Thanks.

 

I use 5W30 in the 4.2, 0W20 would not offer the proper lubrication for that motor. For the 5&3 litres in warm climes, 5W20 is what I and the main dealers have used for over 10 years. In cold regions 0W is better for frigid starts (not to be confused with cold start).

 

At the risk of being flamed by the faithful, I just installed Shell Rotella T 5W40 in my 2008 XKR, for use in Houston where it is also hot most of the time. Yes, Rotella is branded as a diesel oil. No, it doesn't say it meets Jaguar specifications. In a few months time I'll let you know if my engine has grenaded or continues to purr along. I suspect it'll be the latter (or if not, it probably won't be due to the Rotella). As with all oil threads, YMMV.

BTW, for full disclosure, I work for Shell. But not in the lubricants business, so don't ask me about the ingredients in Rotella, I would have no idea.

 

From the XK handbook for my car:

Engine oil temperature ranges
For climates ranging from -35°C to +50°C (-31°F to +122°F), the following oil viscosities may be used:
0W-30 protects from -35°C to +35°C (-31°F to +95°F).
5W-30 (preferred) protects from -30°C to +35°C (-22°F to +95°F).
0W-40 protects from -35°C to +50°C (-31°F to +122°F).
5W-40 protects from -30°C to +50°C (-22°F to +122°F).

Within the typical temperature range of most of the inhabited world, you can use 0W or 5W and 30 or 40 in whatever combination you like so no need to sweat it. 😉
