You are right Glasman. I threw that in for a little trivia & it left a bad taste in my mouth. I still wouldn,t use synthetic because of the cost & then I would want to change it at the intervals for natural oils. Some vehicles like ones with Turbo,s must use synthetic oil. The high heat can bake the oil. I agree with Achip. I get over 200,000 miles out of all my engines. I don,t think different oil would help.
