Yes, it will help keep it cleaner.
I cant help but feel everyone is reading to much into the question.
The oil you are asking about is a CERTIFIED API SN oil for gasoline engines. So yes, its ok to use and yes, since it also qualifies for the diesel rating common sense is it will help keep the engine cleaner as well as less piston and ring deposits.
I agree again, where you live wont matter 5w or 10w
