I don’t know if this is the case for cars since i don’t have one. But driving a warmed up motorcycle is definitely a lot better than just driving it straight away
In: Engineering
When an engine is cold, the air/gas mixture going into the cylinder will allow the gas to condense on the cylinder wall, leaving the engine in a “lean” condition, which is why you had to choke old engines (fuel injection doing the same thing, but automatically). So now there is liquid gas on the wall of the engine washing away the protective oil coating, causing metal to metal contact rings to wall. Additionally, there are numerous corrosive gases generated by the combustion process that will burn out naturally at normal temperatures, but are very evident when cold. All of which adds to initial wear on your engine. I read that the start up process adds more to your wear than the rest of the day’s driving, but have no corroboration on that.
Motorcycles have the same problem, with the possible added problem that they usually run at a much higher rpm and could presumably do mire damage more quickly.
