I have a 1997 Jaguar XK8 that I drive very seldom. I last changed the oil (Pennzoil Platinum 5-30w and a Bosch filter) on 7/24/2012. Since that time I have accrued about 2000 miles. Jaguar calls for oil changes every 10,000 miles. In the past two years I have put less than 200 miles on the car. The oil looks, feels, and smells clean, and I never get any unusual noises or symptoms of anything amiss when I start and run or drive it. I always run the engine to full temperature to burn off any moisture. THAT SAID, I am thinking about putting a new set of tires on and doing some medium length trips (200-500 miles). Should I change the 8 quarts and filter, or just cruise along as it has been???
