Yeah, being an old guy growing up in the 1950s, it's hard for me to pour 0W20 in my Mazda's crankcase. When I first started changing my family's oil, we were using straight 30W or 10W30 and 10W40. Heck, I still use 15W40 in my '96 F250 diesel. So the 0W20 is a big change for me.

But it seems to work well. I regularly experience temperatures in the 90s during the summertime, topping 100F occasionally, and the Mazda seems to take it fine with the thin brew. Of course, I haven't bothered to install an oil pressure gauge, so I don't know what that's doing, but the engine seems fine and uses no oil between changes. So, what's to worry?
