Does my, and your, Super Duty have an engine or a motor? I see the two terms used interchangability, and in fact it seems like motor is used more often than engine.
I grew up thinking they were different, and that my truck had an engine. What do you think? Is there a difference between engine and motor and what is it?
I'd say it's the region of the country you're from, or perhaps in. In the south we say "motor". As in, "Man that thing can motor". Saying, "Man that thing can engine" doesn't sound Southern.
