Motul 300V 5W40 UOA 2011 BMW 328i xDrive

[edyvw]

OK, here is one interesting (I think) UOA.
Oil is Motul 300V 5W40, designed for racing purposes, and this is a current (new) formula with a bit less ester content than before (more PAO).
Specification is KV100 13.5cst and HTHS is 4.1cP.

Car was NOT tracked. Blackstone got used to me sending them samples having dual track/daily time, but not this time. I just did not have time to track. But, I was really interested in how this oil does in a strictly daily regime, considering it is racing oil.
Clearly, as this is simple UOA, not everything can be identified, but oxidation is in check. 300V even when it had more ester was known not to oxidize that much. ZDDP people, please enjoy at your own risk

Good that you got TAN. Looks good.

That was what I was mostly interested in.

THanks for posting, perfect timing. Posting the VOA below for 2023 on this forum.

The oil basically sheared 0 in 5000 miles. Very impressive. Does oil HTHS track with viscocity?

Also, did they tweak the formula a bit since 2023, as it looks like boron and calcium have gone up, or is this an effect of use/ margin of error?

Thanks

not sure what’s going on. Blackstone was saying few years back that their testing is more suitable for UOA, bcs that is huge majority of samples.
HTHS will decrease too.

I don't see an oxidation value on this UOA.

TAN value.

 

[Indyxc]

So the tan went from 3.7 to 4.2 so a very small increase. What exactly does this tell us overall?

I wouldn't consider 6% deviation from indicated viscosity as sheared "0", but then this is also Blackstone, who are notoriously unreliable and don't give accurate fuel dilution figures so It could just be fuel driving the visc loss or the visc loss figure could also just be wrong.

 

[Indyxc]

How did you get 6%? Agree thought that's it's blackstone.


SUS @ 210 / cSt @100
VOA: 69.3 / 12.77
UOA: 69.4 / 12.79

The oil is not acidic. Ideally you want virgin oxidation, and in a UOA oxidation, TBN and TAN. If TAN>TBN it should be changed. If change in oxidation value from new to used changes by 17-20, time to change the oil. However, I believe if TBN is 0 and there are no signs of oxidation the oil is technically still good.

From edyvw's post:

Copy. I was comparing blackstone VOA and UOA, and in that measurement the shearing was negligible.

My concern is that's 2 years old, so I was just going by spec. That said, if the VOA is accurate it definitely underscores yet another issue with Blackstone's testing, lol. I'm sure @kschachn will find that as amusing as I do

Again, Blackstone said few years back that their methodology is geared toward UAO not VOA.
Also, there is 0.5qt make up. So, there is shearing, as there should be. Still, the TAN part is what I wanted to know. I knew Motul 300V oxidation is low. We had UOA here from Corvette 0W40, that had really low oxidation after 5k.
And that thing is packed with additives!

 

[JAG]

Do you mean that you knew virgin Motul 300V oxidation is low or that the used oxidation would be low? What is the connection between the 0W-40 in the Corvette and this 300V?

 

[wemay]

I'd say this oil is fine as a daily. But we gotta consider that edvw's daily commute is more akin to an episode of Fifth Gear.

I will probably run the 5W-50 next fall in my S54 now that I see the phosphorus is FS levels. I am surprised how much Ca+Mg in total is here also. I thought being a "race" oil it would be more like 1500-1800 Ca only and no Mg. TBH it looks kinda like one of the FS SP additive packs + tons of moly.

Previous UOA of 0W40 had low oxidation values after 5k, although they do have hogher oxidation value bcs. ester content.
0W40 is same family of oil. It will have same additives, same purpose. Difference will be in VII and base stock weight.

It does have substantially higher Zinc level.
