Synthetic oil use on flat tappet cam after break in

ir3333 said

synthetic is fine after break in.Is it better than dino oil...somewhere at the bottom of the argument there is a grain of relevance.Is it worth the extra money? I have run regular dino oil in all and everything for 50 years.All went 300k and were running fine when sold.

I tried synthetic but see no benefit. I have run Dino Valvoline Racing since 1972. Change oil every 3,000 miles in everything except the 2009 Challenger. All cars have never had any oil related problems and most have over 250,000 miles on them. They all still run like new.
