XKR cold start

Use an oil additive before changing the oil, one of those Sludge Remover ones. Don't drive while it's in there though, just a few minutes of idling.
Days past, many people added a quart of transmission fluid to the crankcase before an oil change for the same reason; the tranny fluid cleaned out some of the gunk that was stuck.

Follow the directions but usually you just add it to the oil and let it idle for 15 minutes, then drain and do an oil change.

Use 0W-20, not 5W-20
I disagree, and recommend all 5.0L engines use 0W-20 oil that meets the latest Jaguar specification, STJLR.51.5122. For details, see this thread, in particular, posts 18 (including the link therein), 19, and 22. It pertains to the problems with the chain tensioner and guide and improving oil flow at startup to reduce noise and excessive wear.

I know the OP, XJsss, and he is meticulous in maintaining his 2013 XJ SuperSport, which he special ordered. It was one of the first 2013 models delivered, and has always been serviced by the dealer. His car came from the factory with the original design chain tensioners and guides and 5W-20 oil, which was used for several years until Jaguar revised the chain tensioners and changed the oil spec to 0W-20. By that time, the chain tensioner damage had already been done. He has around 100K miles on his XJ and has driven it hard at the strip and other events.
0W-20 is not too thin, since once it warms up it's the same viscosity as 5W-20. The advantage of 0W-20 is faster and better flow at startup.
As I said, your car, your money, your choice.

Most of the chain wear occurs at start up. Before the oil warms up.
I think there is no difference in flow in typical temperatures a XK is started in.
Where 0w helps is after 6 months the viscosity changes, oil becomes heavier, so the thinnest possible oil will become heavier last.

Wow, outstanding responses for a newbee just concerned about a 6 week start-up, but I'm always interested in these types of discussions. I guess my main question for now is why would the dealer sell me the 5w-20 if the standards have changed to use 0w-20? I actually asked (the jaguar parts counter guy) why not 0w-20 for my 2010 XKR and his simple response was the 0w-20 oil only applies to 2015-on. My current plan is to change my tensioners and guides anyway since I bought the car with 87K miles already and no history of a previous upgrade. Since oil viscosity is so critical to these engines, is there a way for the collective forum or jaguar heritage to get a definitive answer from jaguar corporate? Just asking.

I'm not a chemical engineer, but it seems logical to me that oil manufacturers make both 0W-20 and 5W-20 viscosities because there is a difference in flow at startup when the oil is cold. Thinner viscosity flows faster than thicker viscosity.

This is an active thread. I suppose we are all sitting about digesting our turkey over load;-)
But to the point: My cars typically sit for a month if not two. And Try Ottawa some winter... of course I do have an in-line heater.
I do have a startup procedure I follow.
1. Climb in the car and without touching the brake, depress the start button.
2. Wait for all chimes to subside.
3. Now depress the brake and then depress the start button.
4. Wait to revs to come to equilibrium.
The XKR has 148,000 km. Just had the major service done. The oil does not display any misgivings in the engine.
Happy New Year Everyone!

The OP lives in Texas and while it can get cold, 0w20, seriously? I assume the 2010 onward XK owners manual recommends different weight based on climate as my manual (07 - 09) below: Use a 5W-30 engine oil, meeting Jaguar specification WSS M2C913-B is preferred.
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).
Some manufacturers make recommendations for different viscosities under different temps while others do not. I understand many engines from different manufacturers are built to use 0w20, but my 07 wasn't. And specifically, unless I'm starting up in -31 degrees, I shouldn't.
Is there a TSB for the 5.0 XK that recommends the use of 0w20?
