We are talking about internal combustion engines, it is the same, petrol diesel, small, big, just engines that contain oil inside. metal, bearings etc. If a very big truck pulling very heavy weights working non-stop for very long intervals would last very long without oil change why wouldn't a very small car that transports very light weights compare to the truck.
You are a professional Old Mechanic i don't expect you saying oil should never be changed cause you will loose your job.
You don't convince me ever. I will never change the oil!

Your ignorance of internal combustion engines is apparent to any reader. There are large diesel engines that run 24-7 for years. They generally run at very low speeds, sometimes less than 100 RPM.
If you think that is the same as a model airplane engine running at 42,000 RPM, then you need to educate yourself.
A brain is a dangerous thing to waste and the ultimate cost of wasted brains is loss and poverty.
I'm finished here, not interested in free lessons. Try using spell check in your posts.
