My UOA represented several longer trips of 500+ miles towing, truck camper, or both at the same time. My understanding is that fuel dilution would not be the issue with the long trips??? Please help me understand. TIA

Now look at the flash point.
This is why when fuel dilution is a possibility (which it certainly appears to be here) we recommend using a lab that uses GC, which Blackstone doesn't.
It would depend on the cause of the dilution. If the oil is being continuously diluted then it will appear no matter what.
Nevertheless, the point here is that with the way Blackstone estimates fuel dilution (and other issues with that lab) it's most likely not accurate.

This thread title is more hat than cattle 
I know, like, and have used PUP extensively. It’s a really good “shelf” oil that can’t be found on shelves anymore. If you get it on sale on WM or Amazon, it’s a good value. It works well.This thread title is more hat than cattle
However, for those wanting dexos certs, it’s not there. For those wanting an oil that says it’s 15-20k capable, it’s not there. For those wanting very high HTHS & KV100 for a given grade, it’s not there. But guess what? It works really well. I ran 17k+ on PUP in my Fusion. If I hadn’t come across HPL, I would still be using PUP exclusively.
As it sits, if I was servicing FnF that wasn’t willing to spend the ~15% price premium for HPL, I would still recommend PUP. But to put it on a pedestal when M1 FS 0w40 is available for ~$27/5qts, PUP is third-tier at best.
Plot twist.. you are him!

I did the same on M1 AFE 0W-20 in my 2010 FX4 while towing heavy in all manner of climates and conditions. It depends more on the engine than the oil. Low mechanical shear, low fuel dilution, and good engine design trump the oil itself.I proved to you guys years ago based on UOAs that PUP was better than the critics said it was, so it’s quite bittersweet to see some of you fawn all over today like there’s some magical revelation thanks to LSJ
I went 17k+ on PUP about 4 years ago and some folks said I was crazy and that PUP wasn’t fit to be a long drain oil…
Lol, I wish. That career would be more interesting than herding 300 inmates and 14 employees on a nightly basis.Plot twist.. you are him!
That’s fair, lol.
I have a truck that comes into the shop (5.3) with 220,000 ish miles. The guy runs it down to 0% Everytime, and uses our bulk (Mobil 1) dealer oil with a pf63, and no issues at all. I think it comes down to luck of the draw tbh.
Also 6.2's seem to drop lifters more often.

Yep, engineer at work at 170k on a 2015 … M1 AFE @ 5k OCI’s
I would argue against that, based on personal and fleet data. You can search “3.5 EcoBoost” UOAs here, and you will find 99% of the sensationalists screaming 5k OCIs or DIE!! but yet when you look at a good oil (HPL PCEO) going 15-20k OCIs with hundreds of idle hours in some of the harshest conditions known, and there are zero failures or other issues… that’s not a function of the engine.
That’s because the oil is more robust and more resistant to oxidation. I went from subpar 6k OCIs with Ravenol DXG to 15k OCIs using the cheaper yet more robust HPL PCEO & No VII oils with 2.5x longer OCIs. There certainly are some engines that are super easy on oils (Ford Vulcan 3.0 & 4.6 are some) that can go ridiculous distances on just about any oil. But there is definitely a higher tier of oils that show statistically significant performance differences on some of the more difficult engine families.

Yeah, I think it’s very much luck of the draw with these things. I actually think the harder you run them, and the less it switches into V4 mode, the less problems you tend to have. IMO.
They did nothing of the sort. Those videos came after I proposed discussion of repeated Pennzoil VOAs coming in under the 600 ppm minimum for phosphorus.

LOL - of course you would. However, it does not change the fact that I was able to use not one, but two oils that have never been associated with long drains to achieve long OCIs. Mobil Super 5000 for over 10K miles and Mobil 1 AFE for over 15K miles and could have gone further. @dnewton3 was cheering from the sidelines for me to do exactly that.I would argue against that, based on personal and fleet data.

Neither of those oils are “robust” as well as being API SM (AFE may have been API SN, but not SN+) and the fact that I could run them for as long as I did speaks far more (as I have said) to the engine design than the oil itself. Your point is valid in that there are oils that can help compensate for poor engine design and conditions such as your 3.5L Ecoboost example, but again it points to the engine and its design being an issue and not the oil being a savior.

Those were excellent and informative posts. Many thanks for doing that. It opened a lot of eyes (hopefully).
