Which oil is best for the 2.5L Non-Turbo CX-5?

[kymasabe@ya]

I've switched my 2023 CX-5 to 0-20 Valvoline Restore and Protect. Very quiet Oil due to the Moly level of 171. The Idemitsu oil is good because it has a moly level over 600. The Japanese Manufacturers have compensated for the lower viscositiy oils by using lots of Moly in their oils. Mazda, Subaru and Toyota oils are all blended by Idemitsu and have high moly levels. For everyones information except for the Amsoil Signiture Series Oils, Valvoline has the highest Moly levels of all the oils marketed in the United states. The high moly levels used to really quiet down the clattering of my diesel trucks.

I wonder if only the Mazda and other OEM oils have high moly counts, or if the off the shelf Idemitsu oils are high moly as well?

My initial oil analysis of the factory Idemitsu 5W-30 drained at 1200 miles. And yes, you should do this if you want the best chance at long engine life:

Thought I'd share my 1st change at 1200 miles. As noted above, my oil does not appear to be "high moly" either.

Along with Moly, Calcium has also come down, presumably to meet modern standards and reduce LSPI.

My wear metals appear very similar to @ch3no2 's numbers, but with a different (more accurate?) fuel dilution measurement.

I replaced the factory oil with Pennzoil Ultra Platinum 5W-30 for better LSPI protection, cold flow, and resistance to high temp breakdown.

I just did my 2nd oil change and will send off the bottle tomorrow, curious to see how the engine did with 1 year of PUP.

Note that molybdenum is one way to achieve a goal, but it isn't the only way. Also, there are different forms of moly. Some of the ones in use have 2-3x the effect of plain old moly, so 1/2 to 1/3 the amount is used, and you won't know what they are using from an oil analysis. Therefore comparing oils based on moly counts for these two reasons is not useful.

It will soon be time for me to do an oil change and I haven't bought any oil yet. I never see that Pennzoil ULTRA platinum at walmrt, just the regular Platinum, which I've used for a number of years now with good results.

amazon has been my go to for PUP

amazon has been my go to for PUP

I bought there last time, but right now Walmart is cheaper. Picking up some now for the Miata.

The off the shelf Idemitsu oil is the same as that Packaged as OEM Branded oil. Anybody who wants to listen how moly quiets an engine, Run some Royal Purple in your car, no moly in it. Its a great oil but the engine will be noisier. The only Oils that will go into my Mazda are full synthetic Amsoil Signiture series, the full synthetic Valvolines, and oils intended for asian vehicles by Idemitsu. Idemitsu worked specifically with Mazda in the developement of the Skyactive engine. I want my engine internals plated with the Molybdenum and stick to a 5000 mile OCI. BTW Idemitsu Oil In the USA are blended in Their Jeffersonville, Indiana facility. The lower viscosity oils almost require High Moly, tolerances are much higher in these engines chasing the Federal fuel milage requirements.

True, but it is what I use as a marker for use in my Mazda Vehicle. It isnt all unicorns and fairy dust. The true longevity problems are with the Skyactive turbos and not the non turbos. There is no perfect motor oil, but the product it is used in, the way it is primarlly driven and where its driven, and how its cared for guide us to the oils that are most appropriate for an application.

I’ve used Mazda 0W-20 moly since new. No noticeable oil consumption between oil changes.

I’m staying the course

Currently around 89k miles

I find this a very informative oil channel with in-depth coverage of everything oil related

Coverage on additive packages was eye opening as one size definitely doesn’t fit all engines.

Not true. Only the non-turbo cars have the oil leak from the cylinder head crack issue. The turbo cars could have a more rare head crack from the exhaust manifold and this caused a coolant leak. They could also have faulty exhaust valve seals that caused oil burn. This was limited to a specific run of engines, mostly MY 2021. We don't know how many cars were affected by these issues, but it's safe to say there are far more non-turbo Skyactive engines out there than Turbo engines.

Also, I wouldn't get too hung up on moly counts for the reasons I mentioned above, as how an oil actually performs as a package is more important than any single number, especially when you can't compare oils that way, but Pennzoil Platinum and Ultra Platinum have moly as well.

Reports are that Pennzoil Ultra Platinum uses trinuclear moly, whereas Idemitsu/Mazda use dinuclear, making this a not-1-for-1 comparison. You'll see these simpler forms of moly needing to use much more to achieve the same effect. Something like 50-80 vs 250. And, there are other friction modifiers in use in addition to Moly, such as Boron (not its only function though). In my research, Boron does not need heat to be activated, so it works right from cold start. So if you see more Boron in a formula, that could be a reason to use less Moly. Again it's all about how the oil performs as a total package.

Idemitsu no longer sells their premium line in US. So its only the base one now and it is different than the Mazda Moly oem. Still decent oil.
Other oils have Moly too not just Mazda Oem. Although the Mazda oem has a very high quantity of Moly.

Yeah, this guy has some amazing info.
Good info on the Ultra Platinum.

 

[dunhillmc]

Mazda has a new GF-6 version of their high-moly oil that's still made by Idemitsu. They are stocking it at dealers for CX70/90 oil changes

Second oil change. 1 year and 3100 miles on Pennzoil Ultra Platinum 5W-30. Compared to the first change:

• Iron, Aluminum, Copper are lower per mile driven, evidence of engine break-in progressing.
• Silicon is much lower, evidence of engine assembly lube and any dirt or dust getting washed out.
• You're seeing the new additive package coming in from the Pennzoil Ultra Platinum. Molybdenum count is the same as the Idemitsu however it is tri-nuclear and therefore more potent. Boron is a friction modifier working alongside Moly so in total there is a much greater amount of friction...

3100 miles in a year? I have put almost 7000 miles on my bicycle in the last year and 30,000 miles on the cx5 since end of janurary 2023 and 8000 miles on my jeep since april of this year. I think i drive too much

Unfortunately, due to suspension issues I was sorting and the arrival of a Miata to the house, the CX-5 wasn't driven much this summer. Also, my drive to work is 4 miles.

 

[Omg_Onex]

valvoline synpower 5w40 , havoline pro ds 5w40 , total quartz 9000 5w40

I use 3 mentioned above , whichever one is on sale for my 2.5 setup turbo

 

[DG_1234]

My CX-5 and Miata use Valvoline full synthetic.
