On this forum it is commented byJaguar Steve and Tame Technican that regular servicing at the 7/8K rather 10K is far better for the engine etc
Well i had 2K still to go until the next service (8th service) so i thought i'd follow the advice of the experts! i had manged to get hold of Magnatec oil at a rather good price, picked up the oil filter, sump plug and air filter from the dealers and decided i'd give it a quick service so that a) i get used to servicing the car and i get to have a poke around underneath to see if everything is ok

At the last service the dealership used Shell helix F (Ford spec oil), and the previous service that Magnatec 5w-30 Ford oil was used. The first 5 services it has been filled with Mobil 1 5w-30 Ford spec oil and generally been serviced every 7-9K and once at 10K. the car uses just under 0.25 L of oil between services.

i changed the engine and oil filter, old oil looked ok I thought but my friendly mechanic thought otherwise as he smelt it(!) and touched it. His comment being, the car needed an oil change. i left the airfilter at home(d'oh) but still had a chance to see how the airfilter had coped with in the last 17K. the airfilter looked terrible. i really should have taken a picture to post up here to show how bad it looked. My mate wasn't impressed with the 20K service interval for the airfilter. i commented on to him that the car wasn't as responsive and smooth on start up as it used to be.

well the air filter given a good blow with compressed air to clean it out until i replaced it when i got home.

The car is running so much better with the new oil and air filter. it actually feel faster, more responsive, quieter on startup from cold and the MPG has improved by 2MPG.. I was getting 24/25mpg on the way to work. I hit 27mpg easily this morning which is a rather nice bonus considering the drive to work wasn't free flowing..

So from now on i'm going to give it a interim service at 5K with new oil + oil filter and an air filter at 10K..

Got to say these cars need regular oil changes just as Jaguar steve and co have commented.

the car is running sweet!

cheers

i'm always suprised at the mpg on the motorway. town is generally 18-20mpg though and alot less if traffic is stop start.

last week on a spirited 65mile motorway drive (sport button used alot) i got 23. i really can't complain about that with the way the car was being driven!

Doesn't seem to matter how I gentle I am with the right foot I always get 17/18mpg with mixed driving.

Get about 23/24 on the motorway.

i wonder if the later 2000> 4.0 engines are more economical than the earlier 4.0?

I have a 2000 XJ8 and get 18-19 around town and 28 on a motorway run at a steady 75-80.
Quite pleased with that.

I can't think why that would be though other than in terms of general wear and tear though?

Mines a late 1998 with original Nikasil (compression is good so that doesn't explain inefficiency!). I would hazard a guess that the original Nikasil lined engines would be more efficient over short-medium distances because of the better warm up times... But I'm usually wrong about these things!

I reckon my poorer MPG is a mixture of a heavier than average foot and my love of cruise control through Scotland, the lake district and Shap.

I'd love to have a comparison now though... Where's Steve? He's the resident Jag geek biggrin

EDIT: Oh wait hang on you've got an XKR? and BigNige has an XJ8? Lol, Not a lot of basis for comparison here then in fairness!

Air filters have a hard life when you have a forced induction engine (turbo or super charger) The service interval for normally aspirated cars is 40k.

You don't really need to change the oil and filter every 5k, unless you do loads of cold starts and short runs. The oil get diluted buy fuel in these conditions.

The problem with modern cars generally is they feel no better after service, so customers think its a waste of money. In the old days, I put a set of point in my MK2 escort and it felt like it gained about 10 bhp.

Its nice to see you could feel the improvement that doesn't always happen nowadays. When are the plugs due, I always felt superchargers seemed a bit more lively after we changed them, but then we did the air filter at the same time, so maybe it was that.

Often overlooked, dont even think its on the service sheet actaully, check you are getting full throttle, so many Jags have the throttle stop setup wrong, you can wind it down further to the floor under the accelerator pedal (be sure not to damage the wires if its got a kick down switch in it)

I used to believe that the 10,000 mile oil change would be OK with modern oils

Last year I sent a sample of oil to www.blackstone-labs.com in the USA
Only cost $22.50 plus post for a report.

They said there was no fuil contamination but 10K was to long, 5-6,000 would be best


If anyone wants a report email them and they send a sample container with a questionair free of charge
Return it with your CC/DC number and they return the report by email after a week or so

Norman, does your car ever go 5K between having the next set of tweaks?

True on BOTH counts
