My supervisor just picked up a 1998 Jaguar XJ6, with the 4.0 straight six, and the first thing I asked was to see his owner's manual! [Smile]

They recommend 16,000km (10k) oil changes, with no severe service schedule (they say to consult your dealer for advice)

The interesting thing was the listing of viscosities you could use. They list almost every viscosity out there! They recommend 10w30, but also say you could use 5w20 when it's below -10C. Above 0C you can use almost any oil you want, they list 5w30, 5w40, 5w50, 10w30, 10w40, 10w50, 10w60, 15w40, 15w50, 20w40 and 20w50. Very interesting stuff.

The engine holds 8.5 quarts of oil too, which is going to make it an expensive oil change for him, especially since he has an aftermarket warranty which requires 3000 mile/3mo oil changes, and no do it yourself is allowed (this is the same warranty I had on my Firebird, but only followed it for a short time since I wanted to do my own changes)

My old Jag V12 took 12 quarts of 20W50. I used 15W50 synthetic. Oil changes were expensive.

Cheers, 3MP

With oil capacities that large though, the UOAs would probably look much better than we're used to seeing. All that oil would dilute the concentration of wear metals.

Not to be overly critical, but there is no such thing as a 1998 XJ6. Jaguar retired the 4.0 I6 engine in 1997. 1998 brought about the 4.0 V8 model cars.

You're right, it is a 1997! He thought it was a 1998, but I just checked his owner's manual and it does say 1997.

It's only got 37k on it, so he's not too concerned that he just found out (two minutes ago!) that it's a 1997.

Unless Canadian model year designations are different, a 1998 model should be an Xj8 (X308) and have a 4 litre V8, the 4 litre straight six and the 6 litre V12 having been discontinued in the preceding model year.

The straight 6 does take 8.5 quarts and the 6.0 V12 takes 10.5 qts. I use Mobil 1 15/50 in my V12, 10/40 or 10/30 in my wife's Vanden Plas, and whatever I can find for dirt cheap in my Xj6!

With 3000 mile oil changes and that large capaity sump I would not sweat it. I would use either a 15W40 HD oil if temps permit or if it is colder out try 10W30 type II+. With that much oil capacity it should be rather gentel on the oil especialy with 3000 mile change intervals!

I almost forgott to mention that 15W40 Delo or Delvac are about $5 a gallon and 10W30 Chevron Supreme is $1.08 a quart! Penzoil 10W30 is $1.29 a quart.

I like JB's recommendations. [Wink] Pennzoil Long Life 15W40 would probably be my pick this time of year, though.

So Patman, don't hold us in suspense, what's he gonna use? [Confused]

He honestly doesn't know. He's most likely going to use a local mechanic who specializes in Jags for his oil changes, and will listen to his recommendation. I told him he probably should run 5w30 in winter and 10w40 in summer. Due to him needing to do 3k oil changes and having to add so much oil, synthetics aren't a good idea for him right now. I told him once the warranty is up, he should go to 15,000km intervals with a good synthetic.
