That’s a good idea use the 0w16 you have on hand then start with a fresh slate either stick with a 0w16 whichever you can source locally and least expensive or move onto a 0w20 which is always available. My doctor recommends I don’t eat fatty fried foods sometimes I do (0w20)sometimes I don’t (0w16) I’m still very much alive. I remember having this discussion last night the engine and oil pump knows no difference. Maybe one day manufacturers will install a viscometer that’ll be a scare tactic for using an oil “not recommended”
OCM, consult owners manual
Oil Circuit Malfunction, cause
Oil viscosity being used that the engine isn’t calibrated for.
