I'll request that the topic be removed. Didn't intend for this to become such a controversy. Perhaps if I try and retrofit a Chrysler 318 V8 from a 71 Dodge Truck into my S Type I could get better responses?

 

Litres and pints! And manuals that refer to quarts! That may be the reason why the dipstick has a Min and a Max mark, to allow for conversion interpretations of litres vs quarts vs Europe vs North America.

Reminds me of an American definition of an English roundabout - "when 4 or more roads meet and the authorities aren't sure how to handle the problem, they plant a garden in the middle and let the motorists sort it out for themselves.

 

I see no controversy (?) and I think the responses so far were quite helpful. If the manual was the primary or sole authority for oil quantity- why is there a dipstick?

Overfilling an engine by a litre/liter/US quart/Imperial quart will not cause a problem nor will underfilling it by the same amount

 

Robinb -

3 is enough!

We also have mini-roundabouts which are a sort of painted upwards bulge in the road you can drive over. No garden.

 

Ok fellas', just today I changed Joyces 2005, 3.0 Jag, 710 and filter. Now I know the OP refers to a 2001, but to my knowledge they hold the same amount of 710!


Anyways for the past 6 years or so, I purchase the recommended Castrol 5w30 conventional (makes Mikey happy ) just exactly what the manual calls for.


I drain, remove 710 filter all within a beer time frame, as that drains, I fill the new 710 filter almost to the rim with new 710 from a US qt and have another beer. Fit new 710 filter to engine and add the remaining quart (US) plus another quart (US) and a 5 quart (US) "jug" for a grand total of 7 US quarts. Sure I pull the dipstick and check 710 level but really I am only going through the motions. After all these years and 710 changes I know for a fact that the 7 US quarts takes the 710 up to the top but not the hole in the dipstick at the "max. position.


For the Blondes that don't know 710:

I don't think that's necessary Tony, oil is one of those subjects than can spark a healthy debate but no bloods been spilt!

Rick in my British head I buy a gallon can of oil rather than a 5qt jug.

 

Your British Norri


British one gallon can = 1 and 1/4 US gallons? I believe that would be 160 ounces (US).

 

I think it's 1 and 1/5 US gal but I think you can no longer buy a gallon of oil here, at least I've not seen one for a while. Common sizes of oil "jugs" (we'd say something else) are 5l, 4l, 1l.

 

Just embracing our newly renewed national bonds.

 

Yay!

1 imperial gallon= 4.546092 litres

1.25 US gallon = 4.731765 litres

160 fl oz US= 4.731765 litres

160 imperial fl oz. = 153.7217 US fluid oz.

Everyone confused now?

Back to the 'controversy':

6 US quarts= 5.678118 litres

7 US quarts= 6.624471 litres

6 Imperial quarts= 6.819132 litres

The 2003 Owners manual states that the V6 engine takes 6.9 US quarts or 6.5 litres including filter.

The 2001 owners manual for the UK specifies 6.7 and 6.4 respectively and 11.25 pints.

I'm very curious as to why the US version of the manual says 6 US quarts.........

 

That's what my original question was based upon. 7 quarts US measure fills it right up.

 

Looks like they thought US quart = UK quart

 

What specifically does your owners manual say?

 

Here's what JTIS has to say for the 2001 V6

Capacities
Description .................................................. ........................... Liters
Engine oil, initial fill .................................................. ................ 5.5
Engine oil, service fill with oil filter change
Vehicles equipped with T-bar handle design oil level indicator........... 5.7
Engine oil, service fill with oil filter change
Vehicles equipped with loop handle design oil level indicator............. 6.5

 

Mine has the round loop and 7 quarts did it just fine.

 

On the topic of oil, is castrol gtx the prefered oil for these cars? a lot of my German cars love mobil 1.

 

Your oil cap under the hood should even state "Castrol 5W 30"

 

Yes it is recommended, I use Castrol 5W30 too.

I've been thinking of going full synthetic, and going to the 10,000 mile change interval.

I was going to do 5,000 mile intervals with regular Castrol 5W30, but since reading the addendum to the owner's manual thats states it is okay to go synthetic, I'll use that and go to the 10k mile change intervals.

 

The Castrol people would just love to have your money, so they'd prefer that you use their oil.

The Jaguar/ Castrol relationship is purely a marketing deal, nothing in any way related to product superiority. There's tons of posts hare agonizing and arguing over oil brand, type and viscosity but precious little in the way of evidence that any product is superior to another.

Use an oil of the recommended viscosity and API category as specified in the owner's manual. Anything beyond that will be just to make you happy. The car couldn't care less.

Standard oil change interval is 10K miles/16K KM or one year. As noted many times, North American owners are still hung up on extended change intervals even though they've been around for decades.

The standard on the newest cars is 15K miles, so our 10K looks a little old school and conservative.

 

Below is a picture of a US market Jaguar 3.0 engine taken less than 3 minutes ago. God bless Castrol and Jaguar calibrating! Our US parts stores run bimonthly sales on Castrol conventional oil, and yes I take full advantage of the sales! I just go somewhere else to purchase my (unnamed) 710 filter !


Oh and for those that have witnessed Joyces under bonnet, sorry I haven't hosed it down for a month or two, so I apologize for the dust and 710 ring around the filler after this past weekend.
