Hello,

I have Jaguar X-Type 2002 3.0 V6 and I am interested what oil do I use for it?

Last owner used 10W-40, today I saw that I am reaching minimum on oil, so I need to fill it before regular oil change? What do you advise on this?

Thanks

 

I use Castrol 5w30. I believe thats what the manual says. But mine is a 2.5 and should ok for a 3.0

 

5w30, and don't mess around with refilling it... Jaguars need their fluid changed every 3k miles to stay maintained and running. It will take about 7 quarts with .5 in the filter and 6.5 in the pan. Don't blow your engine by just keeping your oil filled because you will blow it

 

10W40 is not a recommended viscosity by Jaguar. Refer to page 7-7 in your owners manual for the correct grades for your climate, most likely 5W30.

 

I have added a liter of 10W-40 now, is it a problem that I change it later or?

 

Every 3k miles?
Is this true?

 

YiorgosX, when it comes to changing the oil in the car, this is like asking what your favorite color is. Everyone has an opinion on it. Changing the oil more often is not detrimental to the car. But, it can cost you in the wallet. So, where do you feel comfortable in how long to drive between oil changes. I would say for you if you are changing the oil every 7-10K KM, you are fine. If you do your own oil changes, what you are shooting for is the point where the oil starts to change colors (go from a light honey color to a dark, blackish color).

In my car, I can see the mileage start to change slightly when I am getting near the time I say the motor needs an oil change (I do it every 4,000 miles/7,000 KM). But, like I said, it is a personal preference though. The big thing is to stick with one grade of oil and use that unless you have very big changes in the weather throughout the year.

 

Absolutely not. Cars haven't 'needed' 3K oil changes since the '60s. Most modern cars go 10K miles between changes (including our Jags), even longer if synthetic oil is used.

Sorry to disagree Thermo, but using oil colour is NOT a meaningful or accurate way of determining the need to change.

 

Thank you both for answering.

If I was asked, I'd use Mickey's approach, but this forum is a wealth of info for our cars, so when I read the 3k oil change I was really shook up and wanted more info.

Anyway, till now at 48k km (~30K miles) I've been changing oil at 16k km, as Jag and the dealer suggested.

 

I change my oil every 3k miles because changing oil is so much easier than messing around with a screwed up engine. Every oil change costs me $20-$25 and if I keep my car for 100k miles, then I'm spending only $660 on oil changes over the rest of the life of the car while someone who changes it every 9k miles is going to spend $220 over the 100k miles. I see the extra $440 dollars that I spend as my warranty for my engine and whenever I change my oil, it has already changed in color. The thing is that oil is "used up" after all the additives in the oil have been used. As soon as your mileage starts to drop, your additives have been depleted and cannot do their job anymore. When your additives cannot do their job, you risk damage to your engine which is why I stay on the safe side and change it every 3k miles. Not to mention the extra 2mpg that I get from changing the oil could also stack up to be close the the extra $440 I put into oil changes. That's just my thinking of why I change my oil every 3k miles

 

Here is a good article regarding this topic.

Other than the 'reduced mileage due to old oil' theory, I partially agree with your thinking, however modern oils used in modern cars 'wears out' at ~10K miles not 3K. It's your choice to do what you want, but there's little evidence to support that it makes any difference in engine durability.

If worn out oil was to cause an increase in fuel consumption due to additional friction, the heat generated by this friction would be substantial- something like driving with the brakes applied. This is an old myth.

 

I was also wondering, do I also have to change the filter each time I change the oil? What else should I change @ 75 k?

 

I've been using Synthetic but have been changing my oil every 4 to 5 thousand miles.

 

mushawatus, it is highly recommend that you change out the filter each time you change the oil. Technically you can never replace the filter and the motor will continue to run. The issue comes that the filter has a bypass feature to it that when the filter gets too full of particles, it will start bypassing the oil around the filter. When this happens, engine wear dramatically goes up. A filter is cheap insurance as I see it.

If you want to understand why filters are important, look at some of the articles written at - Bob is the Oil Guy. This is a guy that has taken it upon himself to learn and teach as much about oil as is possible. he is not sponsored by any oil company, so, when he puts something in writing, that is how it is. He does pictures and very detailed write ups, even has some oil analysis results from various things he has tried out.

 

I use synthetic oil in all my vehicles past and present and change oil every 4k to 5k miles (excluding the Vette). I recently pulled the valve covers on my Durango with 80k miles for a cam swap and it still looks new inside and these 4.7L ohc engines are known to sludge. And this truck pulls my car trailer and plows snow in winter. I use Mobil 1 5w30 since new. The X Type, I use Joe Gibbs DT 40 synthetic (5W40) which seems to work well.

 

hie,

temperatures are usually high in Zimbabwe, I am looking for the oil that will suit these conditions.
