Or do you not agree?

Perhaps I'm missing something here (won't be e first time), but If your trips are always short, is there any good reason you can't let the car warm up better before you drive a single inch ? ? ? The oil won't care if it's warmed up while the car is sitting still, or going down the road. If you want to treat the engine like a disposable Kleenex that's your business. Changing the oil more often if you have a lot of short trips may help the enigine somewhat, but don't kid yourself, you are still getting a SUBSTANTIAL WEAR from your driving habits. You could mitigate 99% of that wear by letting your engine warn up to the point where the coolant thermostat opens before you move an inch. My car's engines have an average age of 52 years. And I drive them hard. But where it comes to lubrication, I make sure they are babied, and that means don't drive off in a car with a cold engine.
