Most cars today don't need an elaborate break-in. Mazda doesn't have a very specific one.

As soon as I drove it off the lot, with 30 miles on it, I took it on the highway and put it into manual mode. From there I gave it several 80% throttle runs in 4th/5th gear up to 4k rpms and let it engine break. I also did one full WOT, which was actually by mistake. I now have 71 miles on it and will drive it normally the next few hundred miles.

Yeah I've had Mazdas before and that's been their guideline for quite some time.

I've never heard of anyone doing this nor would I do this on my personal vehicle. Seems very aggressive.

I've done a lot of research on engine break-ins. I fall into the early moderate load camp to help seat the rings.

I think around 1k miles. On my previous 2015 3 with the 2.0, I changed the factory oil out at 4k. Going with Mobil 1 0w20 Extended Performance.

My "plan" as of now is to use either Zepro 0W-20 with moly or Mazda GF-5 in the CX-30, at least initially. The Idemitsu Zepro with moly, at least from what I've been reading, is the oil that our engines come with. I'm a bit undecided on whether or not to change the oil early vs the recommended 10K intervals. There are many that think removing the initial fill early is a good idea to get rid of any metal debris floating around. There are also many that think leaving the oil until the recommend interval is just fine. My thought.....is that if you are replacing the oil with the same oil that your vehicle came with, vis a vis "break-in" oil, swapping it out early, whatever "early" looks like for you, is not a bad idea. And if you're conducting your own oil changes, you know exactly what's going back in your engine vs even taking it to Mazda.

I got mine and there's a large stretch of road with about 5% grade for about a good 2 miles. Full throttle run from the bottom to the top on the first ride hole from the dealership. I break in all my engines like this, same way they break in racing engines. Every engine I've broke in like this runs good and burns very little oil if any at all.

It's very strange to be as to why here in Canada that dealerships can't seem to get the Mazda 0w-20 Molly oil that Mazda recommends and instead dealerships use Petro Canada surpime synthetic 0w-20 oil and I have called several dealerships across Canada and phoned Mazda Canada Head office and their response was that the oil that the Canadian dealers are useing from Petro Canada is a approved product and meets Mazda's skyactiv g engine oil requirement and as far as breaking it in goes I followed the owners manual to a T and did the oil change just shy of the change intervol at the dealership.

I followed the instruction manual for the first 1,000km. Pretty much do it will all my new cars, drive gently and not at the same speeds for a long stretch of time.

if i was driving on the highway i would enguage and disenguage sport mode so the engine wouldnt be running at the same rpm speed a precise intervolvs useually every 5 km and never race the engine at WOT. almost 17,000 km later things seem to be good and good mpg.

Respectfully....I have never done anything like this to my new vehicles and they also ran good and burned very little oil if any at all.
