I just did a little arithmetic and found that oil changes on my DeLorean average about every 180 miles. "HOWZZAT?", you ask? Well, the car is about 18 years old with about 9800 miles on it and I have changed the oil on average of about 3 times a year. Simple arithmetic calculates about every 180 miles on average. Actually, over the past 5 to 6 years I would put that average at about once every 10 miles or less. "Are you crazy?", you ask. Well, oil has properties other than lubrication and those properties tend to break down over time regardless of mileage. BTW, oil does not "wear out". It only gets dirty or contaminated. My oil has never been dirty but could easily become contaminated between changes. Regards, Ed Thompson (#6419 since 1982) Midlothian, VA
