Engine oil OEM Mazda or Total

Mazda says every 7500 miles for normal duty OCI, and I’ve done every 7500 miles since brand new on my 2014 3z.

It’s now at 187k flawless miles, consumes no oil *at all* (I’ve literally never had to add oil beaten changes, ever, what goes in comes out every time), runs like new, seems easily headed to 250k.

For Naturally-Aspirated Skyactiv engines, it is highly recommended that you use Mazda's own(Idemitsu) high molly GF-5 0w-20. Arguably it is one of the best oil for skyactiv engines.

This oil has good parameters and depending on your driving habits will require change 6k-10k, but if you can perform changes more frequently - even better.

I can personally recommend ***Total Quartz Ineo FDE 0W30****.* This oil has even better specifications than *Petronas.*

I’m using Total 5W30 and pretty satisfied with the performance.

I run Total Quartz 9000 Future FGC 5W-30 in mine. Change every 3500 miles.

But then we replaced it with a SkyActiv Mazda3 that used 0w20 and proceeded to have a good long history with that motor that had 0 oil consumption in 125K miles; I did all of the oil changes myself and it was always 4.5qts in/4.5qts out every 5k miles.

I use the same oil for my C4 1.6HDi, just 5w-40 and it works great, since I don't have a DPF.

for 1.6hdi 2014. i use total Q ineo ECS 5w-30. Reccomended by the factory for engines with DPF.

Many reputable rotary shops have tested numerous oils over the years, and agreed that the bearings do not have adequate protection with 5w-20 or 5w-30, especially if you track the car or do any spirited driving regularly.

I encountered something similar when I took my CE Turbo in for service a few weeks ago. The invoice said 0W20 and when I asked the service manual why they used the wrong oil they told me “oh our technicians know what oil to use, ignore that.” Needless to say I have zero confidence that the correct oil was used.
