Scroll down to the middle of the article (hint: look for bold print) while you read dictionaries, I went to automotive school like 25 years ago and have long since retired. I rest my case.

I've always been told it's not a good idea to do that to a cold engine.

You think revving the engine at start up is bad, try doing it next to a stopped car in traffic.

Revving or putting undue stresses on any engine that is not up to full operating temperature reduces longevity. It's up to the operator to decide "how much warmup" to use before loading an engine. It's their choice. There are thermodynamic reasons that are the cause/effect of "why" it's not a good idea to flog a cold engine.

Yup. Different engine parts expand at different rates, for starters.

And OIL temperature is usually the best indicator of when an engine is warmed up enough to whack it.

Which can be a challenge if you have large amounts of oil to warm. For example, my new Porsche convertible holds 10 quarts of synthetic oil, so it takes a little while to warm up to 160F degrees.

I’ve never known a woman hesitating telling a man he has issues.
I’ll ask my wife and see what she says.

As a licensed mechanic I was also told the difference in trade school many years ago and old habits die hard. it was one of the first things the teacher told us in engine class. A motor has an external source of power and an engine has an internal source of power and that stuck ever since because its true . Ive never heard anyone say electric engine when describing a motor, a thing with windings and a power source. Hey my starter engine failed, the engine for my jacuzzi needs replacing. When I hear someone say "my motor in my car......" I think uneducated. Like many words, the true definition gets lost over time.
