What about zinc?

I agree with A56, but with a qualification.
Engines such as in taxis, trucks etc that are run for very long time periods have less wear over time than stop/start engines. That is because they are at continuous operating temp & the parts are getting lubricated & mate together as designed.
The plan should be to get the engine up to operating temp ASAP....& keep it there. Loading the engine when cold by driving the car will get the engine up to temp quicker. Just keep the rpms & load down until operating temp is reached.
