I have an older Mazda 3 with a 2.0 Skyactiv engine. The OCI in Canada is 8,000 km with 0W20. I will use the cheapest 0W20, so most likely Castrol from Costco.

Is there any issue with extending the OCI to 10,000 km?

Is 0W20 a good grade for these engines or do they like 5W30 better?

0W-20 is the recommended grade and it will run fine in your SkyActiv motor. I would stick with the 8000km OCI.

Sis had a 2012 with the 1,998cc (2.0l) Skyactiv.
I used 0W-20 and a 5K mile OCI. 2 OCI on each filter.

I had her oil analysed once and it was stellar. I stayed at 5K miles.

How long do you want to keep the car?
I wouldn't even go 8K Km which is already a compromise between the engineers & the Marketing dept.

Keeping for a few years at least. In Europe the OCI for these cars is 20,000 km, so I thought I could extend.

How many km do you drive in a year? What is your driving routine like? City or highway? Which part of Canada?

I wouldn't overthink it.l, these motors are very reliable. My family had 3 different Mazda3's with the 2.0 (2008, & 2x 2010s). All had over 125,000 when we sold them, mostly trouble free on 5,000 mile OCI on dealership bulk oil.

Those models had the older Mazda L engine that was also shared with Ford.

Skyactiv is a newer engine with 13:1 compression and DI.

Mix of hwy and city in the gta. No short trips.


I would still stick with the 8000km oil change intervals which is just under 5000 miles. That in my opinion is the sweet spot for these engines. Consider the winter climate as well.

You should be OK if you do highway. Btw, chepest 0w20 here is Supertech 0w20 from walmart, not Castrol from costco. Also go with the bigger oil filter ( 7317 series that fits hondas )
