I'm revisiting my oil selection for our small commuter. Transitioned from a 17 mile to a 5 mile commute. Short trips. 2012 Mazda Skyactiv 2.0 with 80k miles. IVD is the principal concern. I'm considering going back to six month changes if 5-6k OCI is too dirty. Middle Virginia, so only a handful of morning starts below 20 F per year. I've typically run M1-HM, PP-HM, or most recently M1 EP, always 0w-20. Use now is much closer to "hard use" than it was. Stock grade is 0w-20 but I've highly considered transitioning to a 5w-30, obviously in full synthetic...less for viscosity concerns than other matters.
Walmart jug oils are strongly preferred. I plan to use my annual Mobil rebates for our other car, so I'm slightly biased towards other annual rebate/deal brands for this car (PP, Castrol Edge, etc). I've read plenty of love on here for M1EP in GDI application, but seems formulas changed a few years ago (less PAO) so I'm not sure how to consider historical BITOG searches. (I read the 7 page thread.)
Between M1-EP (HM or non), PP (HM or non) and the other variants (M1 AFE, M1 AP), Castrol, Valvoline, etc, is there a current leading candidate for IVD and LSPI?
Dexos1 seems like the best specification I should look for. (I don't think I'm going to find C2/C3, VW 504, etc at WM.)
Amongst a given brand and model of oil (M1 EP or PP, for instance) would grade choice (ow-20 vs 5w-30) contribute to NOACK, oxidation, IVD, etc? Does the HM option typically impact this as well?
