I use Mazda Moly 0w-20 in our 2014 Skyactiv CX-5.
I use motorex 30W in the air (or coil) side. The motorex is great stuff
Remember that the rotary engine burns oil by design and does not particularly like eating synthetics. Expect to use old fashioned dino juice and change your oil every 3000 miles.
Although this is exact replacent, mazda OE still uses Mazda branded GF-5 which is exactly the same oil but branded Mazda....
Love these high molly low viscosity oils. Absolutely the best out there
Motorex 60:1 piston and rings go 180 hours with out issue, could go longer but i change it every winter, powervalve has yet to need to be seriously cleaned in 3 pistons.
I went with the motorex recommended oil. Worked great.
They should be using 0W20 full synthetic oil (not synblend crap). Its not going to hurt running the 5W20 in it instead but next time mention it at write up. Mazda claims benefits such as better cold start protection and better efficiency among other things.
