Does Mitsubishi Yige's new car need engine cleaning?

The engine of the new car is clean, so it doesn't need cleaning. Generally, it runs for tens of thousands of kilometers, and the engine needs to be cleaned only when there is some sludge. I use GT now. Magic? Force? Red engine oil is the base oil of grade IV PAO, which has good cleaning effect. The engine has been very clean, and it has not been cleaned until now, and it is still running well.
