This is my first post; I've lurked and learned for a long time.
2015 Mazda3 with the SkyActiv 2.5L engine. First owner. I ran factory fill for 1000 miles, then Amsoil Signature Series 0W20 with the OEM filter, as there wasn't consensus that the Amsoil (or any aftermarket) filters had the correct bypass spring pressure for that motor. I was a little nervous about the first oil analysis to be honest, as I had ridden with the dealer when shopping for the car, and he drove it hard right after startup - with ~200 miles on it, so I assumed it had a lot of similar drives before I bought it. The comments on the first analysis were that it was fine, other than somewhat elevated copper and silicon, which they suspected was due to break-in residuals. 2nd analysis comments agreed that had been the case, with the only issue this time being somewhat low flashpoint; they mentioned the engine not being warmed up enough, which was true - I drove it up the street for a few miles, but the oil temp when I drained it was probably 100-120 F.
Didn't do an analysis at the second fill as I was moving and just needed new oil. Decided after this 3rd analysis that I'll probably only do it every now and then until I get to the end of the warranty period, at which point I'll start doing TBN and stretching the OCIs. For now I'm trying to keep it close to 7500 miles, per Mazda's spec. I might do one next time to see if it's holding up for the short drives we're doing here.
