Ok first, OP you need to look at this thread -

- Our engine does not ''need'' or ''require'' a 0w-20
Does anyone have any actual oil analysis data that supports any oil or filter over another or is this whole thread people looking for confirmation bias?
For what it's worth I just put 20,000 miles on my last oil change @ 90K miles.
I didn't even need to top it off and the oil still tasted great. I used mobil 1 oil and filter because I liked their marketing the best at the time and it makes me feel good. If my 1986 Toyota Camry owners manual recommended 10K change intervals back then with 5w-30 conventional, then I will do 15-20K now with the right oil.
Unless someone has some actual data I don't think our cars care what oil or filter we use. Just keep it topped off and use what you like.
And another thing, our cars do not require 0w-20. Other countries that don't require automakers to eke out every last little mpg allow up to a 40 or even 50 weight and we all have the same engine, so no we don't ''need'' a 0w-20, that is strictly for efficiency sake. See the above thread link. 0w-20 is ''recommended'' because that's what the advertised and government reported MPG was achieved with, and in the legal world there is a huge difference between recommended and required. In fact there is no actual ''required'' oil viscosity. The repair manual states the oil is ''required'' to have the starburst symbol for automobiles, and it lists a ''required'' minimum oil pressure at idle, and at a specific higher rpm. Those are the only things ''required''.
