Hi all!

As some of you may be aware, I've been doing several UOAs on my CX-5 as I thought the OLM system was a bit optimistic. Check out this thread for review. I mailed my 4th sample on 3/6 so hopefully I get those results soon. In doing more research I stumbled on a Mazda specific forum and was made aware that the OCI was shortened starting in '18. I decided to dig into that statement, at first I thought that this was perhaps done since Mazda introduced cylinder deactivation for MY18, but that wasn't correct. The change actually occurred for MY17, this means that Mazda decreased the maximum interval on a largely unaltered engine. Has Mazda perhaps noticed that their OLM was letting owners go a bit too far and decided to scale back?

The 2016 2.5l produces 184 horsepower, whereas the 2017 produces 187. I can't find any materials which highlight mechanical changes made to earn this increase, I have however read that there were tweaks made to throttle/transmission response so I assume that these were software/electronic changes. If anyone is has more information, please share.

Below are the snippets from each respective manual.

2016

2017

interesting. I know the OLM is very optimistic. I believe I had gone 8k miles and it said I still had 50% life left. I started changing my oil around 6k miles even though I can barely even make it to 3k without having to top off the oil.

For 2017 the SkyActiv 2.5 Engine got a slightly redesigned piston and newly designed rings.

For my CX5 Iím still sticking with 5k oci since I short trip and 5k is about one year anyway.

Maybe they've noticed too much fuel dilution with the longer intervals so they decided to scale it back just to be safe?

This is precisely what I'm wondering. If I had to assume, I'd say this is the answer.

I have an e-mail out to Mazda so we shall see what, if anything, they say.

When I picked up our 17 the salesman gave us the two options for oil change intervals, 5000 and 7500 miles. The IOM was never mentioned.

I'm actually impressed by this. I've never had a salesman know about the maintenance protocol when purchasing a vehicle. Wish more salesmen would truly learn about the vehicles they're selling.

The manual for my 2012 Skyactiv indicates 7,500 as the OCI. I've been going 30,000 with microGreen filters so I change the filter every 10K and the oil every 30K with a total of one quart of top-off oil after the filter changes. UOA results were decent, too.

This video has some explanations of the changes for 2017.

The only change I know if for 2018 is the cylinder deactivation.

Starting with 2016 Mazda put an OLM in the CX-5. The caveat was that if you reach 1 year or 10k miles you need to change the oil regardless of what the OLM says. This was changed in 2017 to a maximum of 1 year or 7.5k miles.

There was another video by Dave Coleman where he held one of the new rings to show but I cannot find it anymore. Itís a bi-directional design.

The best OLM is on my 2010 Mustang GT. It always goes off within 5,000 miles so I can rely on it. Others have gone as long as 8,000 miles on GM cars. I think that's too long as many had issues with timing chains, etc.
