I have an opportunity to buy a 1994 J30 in immaculate condition from my parents, who have owned it for 7 of its 12 years. It only has about 63K on the odometer. However, I don't think it has ever been run on synthetics-just old fashioned "dino" oil. Am I risking anything as far as seal damage etc. in a 12 year old car by changing to GC? My 2 current vehicles have been run on synthetics since new without problems. Also, the owner's manual says the timing belt is good for 105K on this car. I would like to save the 350-400 it would cost to change it right away, depending on feedback I am requesting from you, my fellow BITOGers. The car has been garaged its whole life.
