I've been running Rotella or Delo in my flat tappet cars since 2002. Many tens of thousands of miles. When I pulled the engine in my '67 GTO in 2011 after a decade of using Rotella to install a rear main seal and replace the core plugs, the inside of the engine looked like new. Bearings showed no visible wear. Engine had 80,000+ miles on it since I last rebuilt it. Ten years later, still uses no oil, leaks no oil, and runs great. Same with the '65 GTO, '61 Corvette, and '83 Toyota 4x4. Decades of use and tens of thousands of miles of trouble-free service and counting.
