2003 Jaguar X-type. 2.5L v6 with 65,000 miles. I was wondering what is the absolute best oil I can buy for my car. Also if you can give a cheaper 2nd alternative that would be great too. Thanks everyone this is my first post!
Define your criteria for "best". That will narrow your options.
In the absence of that, any name-brand synthetic 5w30, changed at factory recommended intervals would be "best", according to my criteria (which is 100% un-scientific).
My recommendation for a cheaper 2nd choice is Motorcraft 5w30.
