It seems to work well with the engine which originally specs 0w20 but I can’t say that I found my go to oil due to the shearing that seems to be taking place. I’m not too impressed with that.


I want it to stay in grade, **** it. Is that too much to ask for?!
I do have the option to set my own OCI in the maintenance reminder system, instead of the “flexible” setting which takes into account operating conditions. It was showing 30% left when I pulled this sample, so there’s still oil life left, if I trust Mazda with my whole heart. I’m gonna push it and see how it looks.
