Synthetic oil vs regular oil
167,500 miles on a 1994 LT1. I've never used anything but conventional oil in ANY of my cars, and have NEVER had a problem. On my current car, which has run on nothing but 5W30 or 10W30, no ticks, no tocks, no smoke on start-up, no burning oil, no eating oil either.
you know why? cuz you have a chevy small-block, the best production motor ever. i watched that discovery show mythbusters, you dont wanna know what they put in a chevy small blocks gas tank, but it kept chuggin the whole way.

If you don't mind the drop in oil pressure. I would only recomend synthetics be used just after break in. don't forget that brand new car you just bought w/65 miles on it, that motor ain't broke in yet. putting it in a motor with 75K plus on the odo is as pointless as using Maxlife in a 100K mile leaking grease ball. You wont see any benefit from it cause the motor was'nt conditioned to run it. all you'll do is lower the oil press. and increase the risk of breaching the hydrodynamic barrier formed between your bearings and crank. Not to mention the cost. All the tests I've seen were performed on new engines not 100K mile plus, hard run motors. I'm not saying synthetics are all hype they are better than convetional oils, and when implemented at the right time they will extend the life of your investment.They can talk friction modifiers all they want, I suggest looking up "Oil film and wedge principal". that plays a key part in an older motor with more bearing clearance than new. Who cares about how high a temp it can take? If your engine produces so much heat that you need an oil thats good to 800 degrees you have a bigger problem.
Also don't switch to synthetics in an old motor. Seals worn in to conventional oil won't be able to stop the smaller molicules of synthethic oil from slipping by. Usually only happens on motors with 100k miles or more.
