Im looking for some expert opinions on which oil type is best and when it is best to implement full synthetic. I was once told that its good to put about 4,000 miles on your car to break it in and then to run full synthetic from there on out. I did so on my 2002 Toyota Celica GT and I drove that car hard on a daily basis and put over 100,000 miles on it and it ran just as good as the day I bought it. Being that you could have 5,000 miles on the oil and it would be just as clear as the day it was put in... It had me wondering if there was any real advantage from a synthetic blend vs. full synthetic, etc. Any experts have an opinion on the matter?
