Finally changed the supercharger oil today on my 2005 XJR.

Job took 2 hours with the first hour spent on fishing out the allen wrench that I dropped into the engine block alley so the real oil change procedure only took me 1 hour max.

New oil is clear white like thick water and the used oil you'll see in the picture.

Managed to extract about 6 Fluid Oz. from the supercharger and I have 2 4oz. bottle of the new oil so I used about 1.5oz. new oil to flush/aerated/clean the supercharger and the oil came out pretty brown too.

Pick up about average of 2mpg and stronger and smoother acceleration on the highway mpg.

 

I was lucky and didn't drop mine but I did break a balance tube (brittle with age) for the intercooler. Mine came out pure black with metal dust in it (I used a magnet to test). The blower seemed happier and the car seemed to rev easier. Kind of like when you fill low tire pressure and the car pulls better. I didn't do the flush after draining but plan to do it again in spring. Once you know how it's too easy not to.

The dealer wouldn't touch it, as Jaguar used "lifetime" in service wording. I've talked to owners who had no interest in changing it, even after I showed them my sample I saved, as the dealer said it wasn't required. Clear gear oil turning black could only have been from over cooking. I can't imagine metal dust being any good either.

 

So how does one go about doing this? And is there a certain mileage where it should be considered?

 

Remember, when the dealer or manufacturer says "lifetime", they don't mean the life of the car. They mean the life of the warranty.

 

There is also the point that there is only one way to check the level. Once you've gone that far, unless it has been done recently, you might as well just change it.

 

I am planning to change the SC oil on my 2004 XJR, what is your source for replacement oil? what kind of syphon did you use to get the old oil out?

 

Yes, I'm curious as well about how often this needs to be done? My 04 XJR currently has 45K miles.

 

there are several how-to articles in the X308 section that apply

 

Let me google that for you

Wasn't the smell horrible Vector? Of course l spilled it all over. Cat pits and warm vomit is the only way l can describe it

 

Thanks for the picture in your post Casper, I just changed my SC fluid today and it was much simpler than I thought it would be!

Didn't have to remove everything, just used a bungee cord to move the coolant hoses out of the way while I opened the filler hole and used a syringe with 1/8 tubing to remove about 6oz of old oil out, then filled with 2 new bottles (4oz each) of GM AC Delco supercharger oil ($7 each from parts.com). Will add the SC fluid change to my regular maintenance.

 

Where were you able to locate the syringe to remove the old oil?

 

The syringe if I'm not wrong it's in the kitchen section(spatula, measuring cup etc.) from either Wal-Mart or Meijer can't remember.

 

This chat board is absolutely too cool and the guidance off the hook. So many unique ideas that would never be heard or explained anywhere else. THX !

 

I actually got it from my veterinarian, he takes care of my horses.

I dated a nurse, she got me my supplies. More fun securing the necessary parts that way.

 

I use a meat injector from the grocery store, just remove the big needle and push a piece of 1/8" clear vinyl tubing on it. These things are well made and will last forever.

 

Superchargers are rare in the UK, I don't know a common source for the lube. If I ever manage to do it, I think I will empty and refill, then empty and refill after a week or so, when the new lube should have flushed away the resident grime I missed the frst time.

Flexible small-bore silicone tube is available from hydraulics suppliers, but I don't know if it would be small enough.

edit
I think it might be this stuff available from aircraft engineering supply places

BP synthetic turbine oil
though there do appear to be a few grades.

 

I would prefer the nurse and the meat injector.
