I stumbled across this eBay listing: Jaguar XF XFR 5 0 TVs supercharger Oil Refill Kit 2009 2010 2011 2012 2013 2014 | eBay
A worthwhile product or is it (pardon the pun) snake oil?

 

The very first supercharged Jags (up to the X308 & X100) had a defined oil change for the supercharger, from memory it was something like 30'000 miles?

After that they became "sealed for life" otherwise known as "sealed for the warranty period"

Changing the oil is not a bad idea. I changed the oil in the XJR at 155'000kms and it was black, burnt and far from it's best. Other people have reported similar things even at much lower mileage.

Have a search here on the forum, lots of pics.

Sealed for life LOL

EDIT

Here is the old info from Jag about the supercharger oil Oil Level Supercharger

 

Thanks Cam.
I wonder, has anyone done this on an XFR?
Coz it looks to me that getting at the oil drain/refill plug, let alone removing it, could involve dismantling half of the S/C and/or engine!

 

The fill point seems to be at the back of the supercharger, here's a pic (note that this is with the blower upside-down compared to how it's installed on the engine)

 

BTW, no need to do ebay if you have a GM/Holden dealer nearby.

 

If the fill plug really is at the back of and underneath the S/C then no way am I going to attempt to change the oil, as obviously the only way to do so would be to remove the S/C altogether. And a mechanic let alone a Jag *********** would charge a small fortune to do this. My reading tells me that on the Eaton TVS R1900 as fitted to the XFR there is no real need to replace the S/C oil unless you consistently drive the car hard, eg regular track days. So I think I will give this a miss!

 

Yep, plenty of them near me, the Eaton TVS S/C in either 1900 or 2300 guise is commonly fitted to Holden Commodore LS 1, 2 or 3 V8s here.

 

I looked through Cambo's links and it looks like although the XJR was a nuisance, ours would be an absolute nightmare. I have over 100k on my 09 s/c, and I can't imagine it's a good idea to let it go much further. If nothing else, it may be a performance and efficiency boost.
I'll need to look into it further and see if I can find a DIY.

 

With over 100k you may want to look into a supercharger rebuild and have the oil swapped at the same time.

EuroToys offers a rebuild for the 4.2L SC: Jaguar XF Supercharger Rebuild 4.2L, Eurotoys,Ltd.

Maybe there is a M112 rebuild kit that will allow you to do it yourself or much less...

 

Yeah I can't see this being a huge issue unless you run your car really hard (track days) or have high mileage. I would personally look into it at the arbitrary 100k mark

 

A rebuild was one of the things I was hoping to avoid by changing the oil though.

 

If you have the 4.2L it's not too bad to get at the plug and change the oil.

I used the GM oil too.

Do you happen to have a DIY for that?

 

Cambo has listed the 2 best threads on changing it on the 4.2L. Just look up thread a bit.

Cool. Didn't realize they were the exact same.

 

hmmm .... that's interesting

What year and model is that from?

 

It's off a 2011 Range Rover Sport 5.0L, same as the 5.0L Jags.

 

Can you hear the rotors spinning in my head?

 

They were spinning in mine too for a while.

I had this TVS R1900 off the 5.0L and a spare Gen4 M112 off a 4.2L and i investigated the options;

Fitting the rotors from the TVS to the M112, not possible
Fitting the TVS to the 4.2L, not really feasible

Andre's Twinscrew kit was the answer to these questions.

 

Ah .. but is fitting the 5.0L manifold possible in the 4.2L?
