I just received my Blackstone Labs report for my 2019 Mazda CX 5 GT Reserve with the 2.5L Turbocharged Skyactiv engine. The car was four years old at the beginning of June and this oil was in the car for 14 months and 4975 miles. I am retired so make a lot of short trips and have only put 20,000 miles on the car in those four years.
I chose the Mobil 1 EP in 5W-30 weight which is one of their "extended protection" formulas supposedly good for up to 20,000 miles even though my usual OCI's are only 5000 miles. The filter was the OEM Mazda PY8W-14-302. As I make a lot of short trips I asked them to check for fuel dilution and as I also have some concern about the reported problem with blown head gaskets and coolant leaks in some CX 5's with the 2.5L turbo engines in my VIN range I also asked them to check for coolant contamination. I keep a close eye on the coolant level and so far it has remained at or very near the max level line.
I am a bit surprised though at the viscosity reading but they said it isn't a problem. Overall it looks like the readily available and moderately priced Mobil 1 EP oil is a good match for the Skyactiv 2.5 liter turbo engine.
