Decided to try Idemitsu with Moly to compare to the regular ol' plain jane Idemitsu. Got this oil on sale from Amazon for like $25 shipped, I think.

Also decided to extend the interval a bit, to actually give the oil a challenge. An 800 mile trip right at the end helped rack up the miles over the course of two days. Haha.

The Oil Life showed 40% remaining using the "flexible" oil life setting, which calculates based on engine operations and conditions.

It's a silly comparison obviously, since most of the miles have been in cooler winter Florida temps, vs the 100F summer runs. The occasional 35F-40F (50-65F average) cold starts have been BRUTAL... on my hands while i grip the ice cold steering wheel and shifter. Hahaha. I don't know how you people live up north where its ACTUALLY COLD. Goodness gracious. I want my FL warmth back.

looks like the plain old idemitsu was better. you cant do much better than zero metals. flash point higher and TBN is higher.

I wouldn't call it a fair comparison though. This current fill has 2,000 more miles on it then the regular Idemitsu before it. Its not an Apples to Apple comparison.

Plus like i said, this current sample has lots of Cold starts vs the previous sample which was all summer starts @ 100F

I wouldn’t say that. Aluminum is 1-2ppm less even with 2,000 extra miles + cold starts.

I’ll try to pull the next sample at 3k for a fair comparison between previous samples. It HAS to be better... right?

Is there actually any proof to this?

Mazda purposely uses Moly infused oil from the factory for these Skyactiv engines in ALL their models. I doubt they would be using it if there was a chance for extra deposits. Their goal is to eliminate engine deposits, especially on the intake valves.

The key word here is MAY. My guess is that owners who do not change their oil as specified and run well over the mileage limits suffer from buildup on the pistons and rings. This can happen with any oil but maybe moly accentuates the process.

Oh I’m sure I can run the oil life down to 0% left and probably close to 9-10k miles but I’d rather not. This vehicle is MINT and is the Newest in my garage at the moment. I pamper it.

Maybe later down the road, once it’s retired to beater status, I’ll do some extended runs of say... 15-20k miles just for kicks and giggles because I won’t care about it much at that point.

Who knows. I certainly don’t plan on messing with Idimitsu’s formula with additives. I like it where it’s at.

I agree. I’ve contemplated running this oil in the CX5. It’s a very good oil.

Looks like both this and the Mazda branded oil (made by Idemitsu, as well) are chock full of Calcium, so Mazda has no worries about LSPI on these engines. I don't know why so many Mazda guys keep insisting it'd be an issue. Everything I've seen shows that it only effects turbocharged engines. I have to wonder if they're not setting themselves up for massive carbon deposit issues in their attempt to escape the non-existent LSPI issues.

Who knows. I’ve only run the high moly Mazda / Idemitsu oil a few times. It’s expensive from Mazda and I have no problem running “regular” synthetic in my Skyactiv.

Well, your average SN rated oil has as much calcium as this does. From what I've seen in Valvoline, with it's Na/Ca add packs (which should be the worst for LSPI), there are no issues in the NA Skyactivs either. It's a high compression engine, sure, but it does not seem like LSPI is an issue for it at all.

Valvoline dropped the sodium calcium additive package over a year ago.

And Skyactivs have been on the market much longer than that, with lots of them being fed the old SN oil grade (which Mazda still recommends, and which it's dealers still use as OEM) for hundreds of thousands of miles and nary a problem.

I haven't heard of a single issue with LSPI in any N/A Mazda engine, despite their high compression. If Mazda thought it was an issue, they would have never specced the oil in the first place, and would have updated the spec by now. They have not.

True but the engines have gone through CQI over the model years. I think it’s prudent to run the latest spec even if LSPI is not a issue in these engines. It really depends on how the particular vehicle is driven.


Valvoline dropped sodium and went back to a moly/boron package along with titanium.

Well, it's not going to be much longer now until just about every mainstream oil is SN+ rated anyway, so the point is probably moot. There won't be a choice. I'm sure it will work fine, though, even if Mazda doesn't worry about LSPI in these engines.
