Oil for 2021 Mazda CX-5 Skyactiv 2.5L Turbo

:
2018 CX-5 Sport
I changed my oil 3 times in the first 6000 miles and looked at the filter element each time. The 3rd change the filter material was clean. I think the Honda recommendation is for environmental reasons.

BINGO! Case in point? My ‘17 Odyssey that I traded in. They recommended the oil filter be changed every OTHER oil change, not each time. They’re so cheap so why not do it every time. Not to mention, I would have a hard time remembering if it was actually due following that schedule without writing that down lol!

What oil results is displayed cz5gt? Moly & Boron does't match oil I've seen. Ed

The oil used is Mazda oem 0w20 for the non turbo engine. It has high moly content. oem filter as well on every change.

Can you imagine, with Honda's gas in oil problem in the CR-V, just how great that break in oil will look and perform after 7,500 miles? Ouch.
That won’t happen as Honda 1.5T with oil dilution issue (mainly in cold weather environment and now it’s supposed to have fixed by ECM updates) uses strictly Flexible oil change interval based on on-board computer calculation. I‘ve heard the oil change can be as short as 2K miles when the notification of oil change is displayed.

We can see that by changing oil early most of the silicon, copper and iron is out early as well.
This is from the NA engine but we get the idea. And yes as mentioned above we could conclude that by 6000 the breakin is done already and parts are stabilized.
Whether thats really needed is another matter.
Can you post the comments from Blackstone and the universal averages column on the far right?
Why are you changing the oil the every 3k miles?

Hey guys, I'm getting a new Mazda CX-5 Skyactiv 2.5L Turbo and I'm not sure what oil I should use. I'd like a 0W-30 to help with faster oil flow and easier startups in winter, but I'd also like a higher HTHS and TBN oil to protect better for 10K Km intervals. A 5W-30 would also be good. It will be daily driven in Canada, some spirited driving, but nothing excessive for extended periods of time. Any recommendations for a full synthetic oil for this application?

I looked at Motul's 8100 X-Cess 5W-30, it has an HTHS of 3.5 and TBN of 10+, but I can't seem to find it here in Canada...
I have been using Mobil 1 5-30 EP for the last 53K miles with no issues. I use a 5000 mile service interval.

I was told at the Mazda dealership that they do not recommend using synthetic oil in the turbo engines. They said synthetic is more prone to burning oil consumption in the turbo engines especially when you get up around 100k on the motor. They use non-synthetic in the turbos 5W-30. The owners manual seems to confirm this.

Clowns :) Of course they will say this. Cheap is the word people like to hear and profit is the word dealerships want to hear.

I wonder how many of its customers would buy this kind of talk by the Mazda dealer?
