142,000 on 99 XJ8

 

Today

 

255,000 miles, but had to rebuild the transmission twice. Engine was just rebuilt. It was weak on horsepower, but i think 255,000 was pretty good!

 

Hell man, I'm thinkin' I was doing pretty good with 200,560 kilometers ;o)=)

 

2001 XJ8 L just hit 99,000 miles this week.

 

It wasn't without it's problems. Here's a pic of what was found during the rebuild...

 

107 km I have done the timing chain

Hmmmm...those cams sure look in bad state.
A little previous 'butchery' methinks ;o]
Also the use of poor quality oil not changed very often??

 

Oil and filter were changed regularly at 3000.
Oil types were brand names, not to include royal purple though.

Didn't do any crazy driving, but yeah, something had to cause it. Wish I knew what it was in order to avoid it this time around.

 

How long have you actually owned the car?
How many miles have you placed on it?
This looks like the results of a lot of stop/start driving
and engine not getting up to full operating temp.

My oil changing regime is every 5,000 with Penrite HPR5
which we get here in Australia.
It is fully synthetic 5W40 which I change to HPR10 which is 10W50
during the hotter months.
I also use a PTFE aditive called Nulon E-30
This is used evry six months and I have found it to be very effective,
especially on an engine with VVT's which the super charged versions do not have.

I only take my car out once a week but do a minimum of 300klm....no shopping trips and no drag strips ;o))
I'm still running on the original Nikasil engine and I hope to stay that way with a bit of good maintanance and sensible driving ;o))

I think one of the major factors of long engine life on these is to allow the motor to completely warm up.
These engines were designed as a 'Rapid warm up' design with coolant flow being arranged to allow
for rapid heat of engine head/block and coolant.
The coolant flow in these engines also travels in the reverse direction of a lot of cooling designs and if maintained properly will last the life of the engine.

During start up, the gas pedal should not be touched and allow the computer to do it's thing.
Engine will initially fire up and run at fast idle of about 1200rpm (depending on ambient temps)
This will settle back to around 900rpm until the 'upstream' heated O2 sensors cut out and idle
speed should settle to normal at 750rpm approx.

Here is an article you may find interesting about the oroginal design parameters for this engine:

This gives a good insight to the design philosphies at Jaguar in the early 90's and the demands
of Fedral legislation coming into effect at the time.

 

Thanks for posting that article. When i was getting ready for the rebuild, I was looking for something like that, but never found anything.

Car was bought with 30,000 miles on it. Daily driver. Definitely some short trips, but a lot of highway miles as well.

I was planning on using mobil 1 5w30 year round.

I checked and can't find the Nulon E30 in any stores in the States. Found online, but only thru Australia or New Zealand. I'll have to look for an alternative. I like the idea of adding something similar. Is there a big benefit adding it everything 6 months vs a specific mileage?

Thanks again for posting the link.

 

That's what I thought.
You will find an equiverlant in Slick-50....if it's still available.
Despite what people say, it is an excellant product.
I used to use that in my old Rover 3500 which covered 360,000 miles with two head jobs and still remained on the same bottom end.

The Nulon instructions say to use once every 80,000klm....so my useage is
probably overkill.....but hey, I like the stuff ;o)

 

I have a champagne 2005 Jaguar XJ8L with approximately 76,900 miles on the odometer. I purchased the vehicle on eBay last January from a Florida dealer for $10,300. Since it was a Florida car, the body and undercarriage were in excellent shape. I did inherit an "air suspension fault" and a "vehicle too low" message with the vehicle, but I subsequently converted the suspension over to standard coil/spring. Everything seems to be working although I didn't try out the AC yet (too cold outside). All that the car needs now is a couple of hood (bonnet) struts which are currently on order. Other than that, the car is in splendid shape (mechanical and otherwise).

2001 and 189,000 Km.

Takeo.

 

98 XJ8 - 78,000 Miles
Just getting broken in...

 

Just hit a lucky moment last week, 2002 XJR

 

225,000 miles. Still runs like a champ. It's a VDP 2003 model

 

Owing to the implementation of stricter environmental standards in the Netherlands, I am regrettably obliged to retire my faithful Jaguar from active service. I would like to express my sincere gratitude for its many years of dependable performance. Despite its considerable mileage, the vehicle remains good condition.
