My friend bought a new Jaguar and mentioned the convenience of long 10,000 mile interval oil changes. I was vaguely aware of the Mercedes FSS problem and suggested that more frequent changes would be better, but that if kept to the interval, use synthetic. We both have short commutes so by the time we pull into work, our engines have just barely reached full operating temperatures. I don't know if Jaguar requires synthetic or relies on typical dino oil for the 10,000 mile intervals.

Any thoughts or suggestions for her?
