Using 5W20/30 in an engine that specs 0W20 will not hurt it.
Thanks to Covid, I haven't seen my daughter since early Feb. She lives down in CT. Her 200 with the 2.4L Multiair engine runs great, but uses a bit of oil when run on 0W20 (doesn't matter the brand - Idemitsu, Valv Synpower, and other 0W20's). 0W20 is the recommended viscosity in the owners manual, but to curb the consumption, I started using 5W30 as I had a bunch in my stash. Actually, I used a jug of PP10W30 last summer and it ran smooth and all consumption stopped.
Fortunately, I changed to Castrol Edge EP 5W30 back in Feb, as she is not a quick lube fan (and save $80) and I have a good stash at the house.
I'm not sure of her current mileage, but the EP is rated for 20K, so hopefully this mess is behind us and she can stop in. My Blackstone Labs sample bottle is ready to go.
