This is the third and final sample of this oil.

I dragged this out until 15% oil life left and was just itching with anticipation to get under the car and change the oil and have a look around to make sure all is well. :sneaky:

The 2nd sample @ 7,540 mile UOA thread can be found ——> HERE

The 1st sample @ 5,305 mile UOA thread can be found ——> HERE

Can't wait for the new Havoline Pro RS formula to finally hit ChinaMart shelves so i can try that out. :cool:

I sent a second sample to Oil Analyzers for a second opinion. I'm not sure where they got Diesel out of a Mazda 3 but ok... :LOL: 🤷‍♂️

This oil seems to be on the thin side from the get-go. Would probably do well in a lot of engines that call for 20 grade.

This is not the first time I've noticed Boron dropping consistently with miles driven. Out of all the detergents/additives, it seems to be the one that consistently drops the more miles you put on the oil. I have a feeling if you know the starting Boron on a given oil, you can use the Boron depletion itself to give a rough idea of how much oil life is left.

BS less than 0,5% fuel, and Oil Analyzers 4.6% :oops:

Yea I thought that was very strange as well. Somebody is obviously wrong here. Blackstone’s flashpoint doesn’t coincide with 5% fuel or else I’d expect it to be 320F or something ridiculous. 😆🤣

Oil didn’t smell like fuel (just nasty used oil stench) and my sampling technique was the same as always in order to pull oil that shows accurate daily operating conditions (after coming home from work) 🤷🏻‍♂️

🤔 hmmmm. Interesting point on the Boron. 🧐

Regarding the thin viscosity though… I don’t think that’s right. If I bought a 5w30, I want it to stay that way.

I use this same oil in Wifey’s GMC Acadia that spec‘s 5w30 as well as other engines that also spec 5w30. I don’t want a 20 grade to be flowing thru there.

But it might just be this engine & driving style that shears the oil a bit. 🤷🏻‍♂️

Well, GC directly measures fuel content, unlike Blackstone's "inference" method. And Blackstone doesn't know the virgin flashpoint of each lubricant, which puts it even more out of whack.

PDS shows 10.8cSt @ 100C for this oil for the SP version and a flashpoint of 460F. Gasoline is ~0.5cSt, the Widman calc gives us ~9.2cSt with fuel dilution, so some mechanical shear there too.

It has been said on here multitudes of times that Blackstone’s measuring of fuel dilution is off.

Can you really infer viscosity with gasoline based on the calculator only? Or can gasoline have an effect on some viscosity improvers or something, and affect viscosity more than "just" dilution?

Yea but I still expected SOME amount of calculated fuel dilution based on flashpoint alone… isn’t that how we always do it with BS’s reports? 😆🤣

The calculator just calculates, as the name would imply, the final viscosity of the two fluids if they were just mixed virgin at those ratios. I use it as a figure for what the viscosity should be if the ratio of the fuel to oil was the only factor in viscosity loss.

Of course, as we know, that's not the only factor, which is one of the reasons (along with lab accuracy as to fuel content, batch variance...etc) the OP's result didn't match the calculated figure. There is more in play.

@MolaKule would be more knowledgable than I on the impact, if there is one, of fuel on VII polymers.

The problem with the Blackstone reports is of course that, since they don't actually properly measure fuel, and the percentage is subsequently always so small, that a lot of what would rightly be attributed to fuel dilution if from a lab that used GC, instead gets construed as mechanical shear.

Thanks for the tip - I was not even aware of this offering until you mentioned it.

This appears to be an "ultra-premium" offering that is positioned above their current ProDS. I think they are employing a strategy that is similar to Valvoline's Extended Protection.

Classic silly marketing. Premium and best should be swapped. It's either the best and it's at the top, or it's not the best.

That's just semantics.

But yes, I do think most oil brands have way too many products.
