It's not my car, just in charge of the maintenance. The driver drives really spiritedly all the time. High revs, high load even with a cold motor. UOA looked good despite this. However... What all can I do to aid in protecting the engine? Or is there really nothing besides good oil?
Change it regularly. It probably won't even know the "abuse".... That's how I treated my first car, 1986 Mustang 2.3. 2 throttle positions idle and at the floor. "Warm up" was a 2k fast idle on the carb. After that it was go time, warm, cold, ice cold.
At 175k she would start right up, idle like a kitten, and run to the "redline". There was no redline, the tach stopped at 6k and even at the floor you just lost "power" as it approached it.
I know, I made some of you vomit in your mouths. But, really even yesterday's engines were fine with this "abuse".
