I use K&N Air filters on all my cars, even the wife's PT Cruiser. Just remember to service them.

 

In my owners manual is show oil capacity with a new filter as 6.1 quarts. I do the 5.5 quarts first and top it off until it is full and with the markings on the side of the bottle it usually very close to the 6.1. Good idea with the K&N I run them in all the cars I have had and never had a check engine light for an MAS. With a standard replacement filter I had to change the MAS on the Benz I had, then change to a k&N and drove it 70K with no problems. Just make sure U clean it once a year, unless you live in the desert and when reoiling USE AS LITTLE OIL AS POSSIBLE, the cleaning takes off very little oil, if you see a white or light spot on the filter LIGHTLY oil the spot. People claim to have trouble with K&N filters 9 out of 10 times is they use too much oil after cleaning. the oil blows off and onto the MAS and there is your check engine light. You can check MAS aerosol cleaner on the MAS by the way it works well. Make you you clear the code after you reinstall the MAS. BAH HUMBUG.

 

andahaion - do u do an oil change every 3k miles for your jag?

 

Due to the great transit system here in DC, I drive about 5,000 miles a year. I do two oil changes, seasonally. Once in the fall and once in the spring. The dealership nearest me seems to always have a coupon on their website for a $49 oil change, so I take advantage of that.

Could I get by with only one change a year? Sure. But that's just me being me, I like to run a tight ship. I like my routines. Also gives me a chance to have her looked at twice a year by a professional.

 

thanks andahaion. i was asking b/c my boy has a 01 mercedes E320 and oil changes are reco'd every 13k miles. this is my first jag, and wanted to check to see if the oil change time was similar to that of my boys mercedes.

 

No problem. Theories on changing oil are ubiquitous around these parts. I think you just have to go with something that makes sense to you and your car.

 

Frontrunning,
I use the entire 6.3 Quarts which puts the level right in the middle of the Low and Full marks on the dipstick. As far as changes go I change oil and filter every 4500 to 5000 miles with a good grade petroleum product. I used to change at 3000 miles but things have changed dramatically over the years and oils can provide superior lubrication for much longer than before and I'm comfortable with that.

As far as a K&N air filter is concerned I've had them on a couple different vehicles and for a daily driver you're just fine with a good quality paper element. Yeah a K&N will last a long time but it is also a pain in the butt to service. Wash, drain, dry, oil, wait, re-apply as necessary. It takes hours to execute this and if you're not careful and put too much oil on the element you can screw up the mass airflow meter. On the Jag I use a good paper element and change it out when it collects dirt that wont shake out. In 65,000 miles I think I've changed it twice. Takes 5 minutes instead of 2 hours.
