dparm, what tires are you running on that beast? What harness are you using?

I do not think Motul 300V is anyway designed for 6k OCI.None of the 0w40 samples stayed in grade. I say forget running 0wXX in the Texas heat, and run Redline 10w40.
Too much esters. It has higher natural alkalinity. Same is with Redline too.With respect to the viscosity, M1 starts at 12.9 CST, Motul starts at 13.6. In grade is in grade, but a head start by one or the other, per se, is going to show in the final results all else equal. I notice the flashpoint in the UOA is a tad higher even by just a bit with the Motul, which doesn’t take much fuel to lower viscosity by even a little bit. The fact both oils did well relative to starting in the lower 40w range, says good things about both. For sure, if staying in grade is important a 10w40 may do it.
Motul looks to be fine with respect to the OCI, TBN is strong and wear numbers are great. Not sure how Motul is not “anyway designed for 6k OCI”, the analysis shows it did well.
The higher AW content sure could be why aluminum is down on a longer OCI. As well, could be the higher numbers overall are leading to the better TBN.
Anyway, Happy Thanksgiving all!
It has also better additive package for sure, and definitely more suitable for track.Looked like moly, zinc & phosphorus are quite a bit higher in the Motul 300V vs. the M1.
Do you think that played a big role in the reduced Al wear numbers?
For oil with that Ester package, TAN looks excellent, but it is getting there. Motul has oils with intended long term use, 300V is not one of them.Good info. What would the high natural alkalinity not show in an analysis that would be detrimental? Asking sincerely, as the analysis looks really good.
Ahhhhhhh... With that said, when TAN crosses over and becomes higher than TBN isn’t that a sign change it? Like you said, M1 TAN was high as well, and was higher than TBN. Should both of the oil brands been changed earlier then? What makes 300v a bad choice, based on the numbers we see, compared to the M1? If TAN is helping us understand acidity, then ester or no ester, 300v did better compared to two of the M1 samples with respect to acidity regardless of what Motul claims or doesn’t claim for extended use. I think that makes sense?For oil with that Ester package, TAN looks excellent, but it is getting there. Motul has oils with intended long term use, 300V is not one of them.
Now, I am not sure we have VOA of 0W40 300V to see where TAN is. This ESP also has high TAN, but then Mobil1 is known to use Esters too, though highly doubt it is anywhere close to 300V.
He is tracking vehicle a lot, and oils are going to see much higher temperatures than normal, will oxidize more, so there is no need to run them long, nor it would be prudent.
I never said 300V is bad choice. It is right choice, it is better choice than M1. It is dedicated racing oil. But it is not designed for long OCI's, that is my point.Ahhhhhhh...

Now, it would be interesting to see how M1 0W40FS version does in same engine.Agreed, wasn’t trying to put words in your mouth. Now I understand what your reference point is with respect to the length of an oil change with 300v. Agreed as well M1 doesn’t seem to be a longer-term oil in this application either.

I just posted in thread with your UOA.Nice analysis’ for the driving style. Wish my LS7 looked this good after track time!
I think that’s a good idea!I just posted in thread with your UOA.
Why don't you try Motul 300V too? 5W40? It would be good comparison with Redline after your RL 5W40 run.
