Periodic maintenance of my 400 BHP supercharged Jaguar XJR

I changed the engine oil and oil filter and also decided to clean the K&N air filter. I have been using the same filter for 15 years now!

BHPian Jeroen recently shared this with other enthusiasts:

It was time to do an oil and filter change on the Jaguar.

I always use Kroon oils these days. For several reasons. My local parts guy stocks just about all their products. My Jaguar specialist friend Raymond uses it.

This stuff ain’t cheap! Euro 120 for 8 litres of oil and an oil filter. And that’s just the parts, I don’t charge me for my labour!

You have seen me do this numerous times in this thread. Its an easy job. I reverse the Jaguar into my garage. Nose sticking out, in this position I have easy access to the oil plug and the filter.

As always, I used my trusted oil filter spanner to take the old filter off. Only handtighten the new oil filter!!

I drained 7 litres of oil from the engine (the engine was still at operating temperature) and the filter into my special oil drainage canister. I pop in the drain plug (after cleaning) and put the new filter on.

Next, I pour that into the (now) empty oil containers and take it to our council tip for proper disposal.

In all honesty, most of the work is cleaning up and pouring the oil into these smaller containers.

I also did my air inlet filter. I have one of these fancy K&N filters. It means removing the air mass meter and inlet pipe. As always one clip on the filter housing broke. JB Weld to the rescue.

Not too bad.

I have had the same K&N filter for 15 years now. So it certainly proved itself in terms of value for money. Mind you, you do require special cleaning and recharging fluid which doesn’t come cheap.

To what extent the K&N filter provides more power/torque I don’t know. My Jaguar packs 400 HP, so a few more extra horses will go unnoticed by and large.

The biggest pain of these filters is to have to clean and dry them. You really have to let them dry by just leaving them overnight. It’s getting cold and wet here now. So this morning the filter was not dry. So I placed it carefully, on top of an old towel over one of our radiators. Don’t tell Mrs D. She goes ballistic when I bring parts into the house!
