Hey all,
My wife and I are considering a pre-owned CX9, but lately I've been hearing a lot of issues with oil consumption on the 2.5T and it's getting me a little concerned. My brother's 2019 non-turbo Mazda3 has had its oil-low light come on a couple of times, and he does top his oil off from time to time...which I find pretty concerning for someone who drives what I would consider very normally, somewhat spirited with a decent dose of mechanical sympathy. Just recently, some guy left his 5,000 mile CX50 in sport mode for a good part of its life and almost ran out of oil, failed an oil consumption test to which Mazda US has basically told him to get bent. Suddenly, I'm hearing people chime in and say they've had to add oil to their very young 2.5 turbo engines well within the service interval.
What? Why? How could a new engine be taking even a noticeable amount of engine oil under normal driving? No one is tracking their CX50 here, and these things don't have 300,000 km yet. I'm looking at keeping this CX9 for the long haul and I don't want to be stuck with a oil burner.
So, in an 8,000 km / 5,000 mile interval, how much oil does your CX9 take?
Do you do your own oil changes on it?
Have you measured what comes out vs what you have to put in?
Did you ever get a low-oil light?
