I am about to change the oil in my car for the first time. It has been going to be dealership so far. The cap says recommended oil is 5w-20, however the owner's manual says 5w-30. I live in Florida. Any ideas on which one is accurate or more appropriate?

Also advice on best oil filter wrenches for this car will be appreciated. Thank you!

 

I checked on the Topix website and the first edition owners manuals do indeed show 5w30 as being the recommended oil. However the second edition of the manual states 5w20 so I presume the manufacturer changed the spec as more knowledge was gained on the engine.

 

Yep, 5W-30 was the original spec for the AJ126 V6 when it came out in 2012 but about a year later JLR changed it to 5W-20 then a year or so after that they changed it to 0W-20. My Oct 2014 built V6 engine has 0W-20 on the oil filler cap.
Any and all of these specs will be perfectly OK for your 2013 XF, and being in Florida I would lean towards the higher viscosity 5W-30 seeing as the latest 0W-20 is really meant to cater for very cold start up temps. Lots of debate as to why JLR went with lower and lower viscosity but the two main reasons appear to be slightly better fuel economy and reduced emissions of the dreaded CO2 (per CAFE and Euro regs) and improved lubrication of the timing chains and related components at initial start up.
Whichever way you go you want an oil which meets ILSAC GF 6A.
For the oil filter canister removal tool you want a cap style tool with 15 flutes and an internal diameter of 88/89/90 mm, I use one marked with "907" which works well.

 

Thank you! This is very helpful information. I appreciate it.

 

I seem to have successfully changed the oil this Wednesday. Used the evacuator pump and changed out the filter. The car indicated oil levels are okay. However I seem to only have used 6.75 quarts of new oil, while the specs call for a capacity of 7.7 quarts. I am assuming I left some old oil un-pumped from the car. Is this within a normal range of what gets left behind or should I do something differently next time?

 

No oil is left behind. I checked when this system first came out. I vacuum pulled the oil out then took out the oil pan drain plug. I only got a few drips.
After that I was satisfied that it worked and have only used the extraction method since.

You have not given us your car details so it's hard to say? AWD or not? It makes a difference.

It is a 2013 3.0 XF. I think he is using the wrong number for oil volume.

 

It's an 2013 Jaguar xf 3.0, gasoline, RWD. What should be the correct oil volume?

 

Why not measure the amount you extracted

 

First thing I did. It was only 5.5 quarts. But 6.75 quarts went back in. I am aware of a slow gasket and valve seal leak, so didn't expect the oil that came out to be fill capacity anyway.

 

Correct oil fill is 6.5L. 7.7 quarts sounds like the V8 fill which is 7.2L. Both values include oil filter change.

 

Nope.
The V8 (AJ133) and V6 (AJ126) take the exact same amounts of oil, 7.25 litres for RWD and 6.5 litres for AWD.
The OP's car is RWD so it should take 7.25 litres.
My F-Type is the same AJ126 engine and also RWD and it has taken smack on 7.25 litres every single oil change, about 10 of 'em so far!
6.75 US quarts is 6.388 litres.
So something is a little screwy with the OP's refill amount, my WAG is he didn't get all the old oil out.
It's not unusual for the vacuum seal of the extraction tube around the extraction pipe to be a little less than perfect which can lead to less than optimal pump performance.

 

That's what I figured happened - I didn't get all of it out. I will be more diligent the next time. I am assuming it is at around 85% replacement right now and not anything big to worry about. Might change it a bit sooner for the next round.

 

Yep, it is now common knowledge that the JLR recommended oil change interval of 16,000 miles or 12 months whichever comes first is a sick joke and the change interval should be closer to half that. Maybe if you do very low annual mileage, less than say 3,000, you can get away with annual oil changes, but if you do lots of miles then you should change the oil at least every six months or 8,000 miles whichever comes first. Many around here change the oil every 5,000 or even 3,000 miles, the AJ126 (and AJ133) engine is very fussy about clean/fresh oil.
The main problem with 16,000 mile oil changes in these engines is the build-up of sludge and varnish, not oil degradation as such.
The sludge can block the timing chain oil squirters (three behind the timing chain covers) leading to premature wear and "stretch" of the timing chains, as well as other problems.
These engines are prone to sludge build up due to a combination of GDI, the PCV system and the EGR system and the best remedy is to change the oil often.

 

I stick with a full synthetic that meets the exact Jaguar spec in the manual, usually in 0W‑20 or 5W‑20, and I change it often on the supercharged motor.

 

I’d just stick to the Jaguar spec in the manual and pick a good full synthetic that matches it, usually 5W-20 or 0W-20 for that engine. I’ve kept my own cars happy by doing the same and using short intervals. I’ve even grabbed oils from places like https://www.coxmotorparts.co.uk/hond...approved-oils/ for my other car, and the legit, approved stuff has always treated me well.
