SkyActiv Oil Analysis Thread

yea but it does have the intercooler getting air flow

True but that's not cooling the turbo down. The intercooler (air to air) lowers air temp exiting the turbo, before it goes into the intake valves. It's the oil that keeps the turbo's moving parts from overheating.

Also the Turbo has oil cooler if i recall. So the oil temp should be better than the NA.

Does anyone know where the oil cooler is?

Engine the oil cooler is below the turbo at the rear.

May be we should split the last 10 replies into a new thread?

I agree it doesnt make sense to continue adding posts as it makes it harder to find actual oil analysis which is the purpose of the thread

I mean, we're still talking about oil.

Skyactiv Oil Analysis is the thread title and topic. It's for posting Used Oil Analysis reports and discussing the results of those reports. Discussing OCI is relevant to a degree, as some people will change their OCIs according to their UOAs. However, debating the manufacturer's recommended OCI, discussing oil coking, etc. is unrelated.

Keep it on topic please.

First UOA on a new to us 2019 CX-5 purchased from a Mazda dealer. Sticker indicated it used Qualker State 0w-20. The aluminum was a bit higher than anverages. What say you all about this? Is this normal for a CX-5, especially one with cylinder deactivation?

 

[N7turbo]

I would not say that 5 is high considering 6188 miles on the oil. I would defer to their expertise whether it's abnormal to see aluminum higher than iron.

... The aluminum was a bit higher than anverages. ...

Our 2.2 diesel UOA's average 8ppm aluminum and 51ppm on the iron for all the reports from 0 to 75k miles.

As a comparison point. I think your 5ppm aluminum is fine. No worries.

Cant open the file for some reason but Check my past UOAs of the same engine (past posts) if curious. I have done multiple UOAs from new.

5 is not a lot. Your are fine.
Changing oil earlier or using Mazda oil should drop those even lower.
