The more mileage you put on between oil changes the more justification there is for full synthetic. Use an oil with the proper additives if you have a flat tapper cam. 10-40 is good for most motors depending on the bearing clearances. I use 10-30 Brad Penn for my drivers including my SS427 and straight 30 weight Redline on my race car.
