Yes. I have looked at carfax records of many CX5s over 120k some up to 200k (both turbo and non turbo) and almost all had regular 5-7000 miles oil changes. Some changes at independent shops some at dealer. Which means they used whatever oil.
Thats great! Thats real world results right there and tells me with proper maintenance, the Skyactiv G is a great engine..
Wow.. your comment prompted me to do a search and i found a forum discussing that issue . due to cylinder deactivation? LOTS of people had problems.. i had NO idea this even happy it’s disappointing the hear the way Mazda was dealing with folks according to their testimony. Thats disappointing. Wow
Unfortunately a small batch of them had this issue. I will say though, the Skyactiv 2.5 is otherwise one of the best engines ever made. Not just from a reliability perspective, but the overall design and tuning. I have seen this engine hold nearly 50 degrees of ignition timing at 14.5:1 AFR during low rpm cruising (According to Mazda edit) While tuning on Ethanol-free 91 Octane fuel. Aside from standard wear and tear (If you want to also throw the valve cover gasket job into that category) I've literally never had an issue with this engine, ever. Only now am I dealing with a tiny air pocket in the top of my radiator which I suspect it due to a small leak in the radiator caps return valve. The best tank I have ever managed with this vehicle, tuned, while employing my usual driving habits, mostly on one lane roads with little traffic is 5L/100KM. That's exactly 47 US MPG.
I really think the only reason for the lower weight oil is to qualify the car for gas mileage and emissions rules. If your only keeping the vehicle while it's under warranty it doesn't matter too much. If your keeping it past warranty 5w-30 is a smart choice imo.
