M1 regular or EP easy to get been doing it in my Skyactiv for 120K still runs like the day I picked it up new. Currently running HM formulation with ultra filters.
True...can’t go wrong with M1. Used the 0w20 age for many miles in my half ton dodge with great results before playing around with a bunch of different oils later on.
Neat setup, but 5qt jugs are perfect for this Mazda
If you are dumping sumps every 6 week on the low end or 7.5K on the high end - why not try supertech or rural king ?
1. This is my first gdi car and concerned about fuel dilution & deposits
2. The cylinder deactivation is controlled by a variable pressure oil pump that activates/deactivates CD adjusters with oil pressure. For this reason would rather go with more of a name brand premium synthetic that is perhaps more likely to hold grade. More of a peace of mind thing I suppose
