There goes a saying, 'the time when you done most damage to the engine is when you start up the engine'. Does this apply to rotary as well?

I would assume so.

When the engine is cold, parts dont fit (made to fit when hot, as heat=expansion).

When the engine is cold the oil is cold, and doesnt do its job as well.

Engines are designed to be run @ operating temperatues because thats what there at 90%+ of the time unless your only doing 2 mile school runs every day.

M-Ster, even now I don't race past 3000 revs when the engine is cold. Once warm do what you like.
Most of my cars have been treated this way and last 100k miles no problems.

It's a hectic world out here, I don't normally have time to let the engine sitting around to warm up for 5-10mins before driving off, BUT I do have the habits of not reving past 3500 on my miata til the engine is properly warmed up.

The reason why I've even asked this question was I thought since the rotary has so much more lesser moving parts and not as delicate as those valves, pistons and cam sharfts, I thought the rotary as compared to the ordinary engines would have a minimum damage, when one starts it.
