Seems like MAYBE you could get away with a non-API oil (I would use an API for a year or two/20K) but sliding up on the viscosity, that's on you.
I am not lecturing you, or telling you not to use HPL, but just letting you know. I personally decided to go 0W-30 on both our 0W-20 engines, so it would be pretty hypocritical to do so.
That said it would be ridiculous if Mazda claimed 0W-30 did harm. That would be on them.
Your call man.
