HPL PCMO 5w-30

[Toyotech454]

This is the first sample of HPL in my/my wife's 4Runner. Previous two fills were Penzoil Ultra Platinum 5w-30. This vehicle has received mostly 5000 mile changes with store bought synthetics (PUP, Mobil 1 0w40, Castrol edge etc...) since 10,000 miles when we purchased it. I did a "short" interval in case any cleaning occured, and to set a baseline for analysis, the goal is to do 10,0
00 mile intervals with HPL. Absolutely nothing showed up in the filter, like previous oil changes, which was nice to see.

The vehicle sees mixed usage, plenty is typical in-town/ highway driving. We reside in a city, so the vehicle does see some short trips where it does not reach operating temperature. It gets used for ski trip duty up steep canyons in cold temperatures, and also sees extended periods of 80+ mph longer trips loaded with camping gear, as well as plenty of time in low range off-road in rocky/dusty desert and high desert environments. I would consider the use of this vehicle on the severe end of things, durability and off-road capability were primary concerns when we purchased it.

Held its grade pretty well.

I love HPL, and I’m certainly not going to dissuade you from its use, but your 4Runner is certainly not in need of an HPL-caliber oil for 10k use. IMO, do an in-service sample at 10k (I.e. don’t change it before sample results come back), and sample again every 5k til it’s either out of grade or TBN < 2, or TBN < TAN. If you’re paying for the premium stuff, you may as well maximize its benefits!

I’m totally surprised your PUP tests stayed in grade…in fact may have thickened relative to VOA, which I thought was under 10.0.

Why? At 5k OCI PUP, or basically anything for that matter, should do great.

It sounds like you'll keep testing at 10k intervals too? Report looks great.

They "flagged" the aluminum but don't worry about it as the Virgin oil has some amounts of Al as well, forget the details but IIRC it has something to do with the type of moly they use.

You can see the Al here in the VOA database:

I almost totally ignore single-digit results on UOAs. Discerning a problem from one sample and a couple ppm of an element is an exercise in futility, or lying to yourself.

I know the HPL is overkill for that interval, just like a store synthetic changed at 5k is, but I am not trying to maximize value, just trying to maximize protection and cleanliness, and not change oil quite as often as I have been.

I will, although I don't expect to be near the limits of the lubricant, even with the way the vehicle is used.

Because there is no appreciable fuel. People on here keep conflating a viscosity loss due to fuel contamination and one that is actual mechanical shear of the VM. One has something to do with the oil and one does not.

Considering the vast majority of UOA are Blackstone analyses doesn't help.

Nothing wrong with that. Thanks for the update.

Plenty of life left in the oil to continue running safely, why change it? That’s a great report.

I love you guys! Not trying to talk him out of HPL. Very good.

We have seen on this board highly extended oil changes cause deposit buildup, even with great UOA reports. I do wish I had a vehicle I was willing to risk super extended oil changes on, but this isnt the one to do that with.

Where/when did we see this? Curious.

This is the example that sticks in my mind, I want to be clear that I do not think that deposits on this level would cause any perceivable mechanical issue, I still do not want them forming in my engine though.

Thread 'Valvoline R&P, 5w-30, 5k oci, Toyota 4.0L 1GRFE'

Jul 8, 2025

2007 Toyota FJ Cruiser 4.0L 1GRFE gasoline v6 w/237k miles. I've owned it since Jan 2009. It's never consumed any oil and it didn't this time either. Still on the full mark when I drained it.

out and off = 6.5 qts Valvoline R&P 5w-30, Purolator Boss PBL30001 full flow filter, and Amsoil EaBP90 bypass filter.

in and on = 6.5 more qts of VR&P, and new EaBP90 bypass filter, and a new Fleetguard LF3487 full flow filter. This is my forever oil for this vehicle, and I'll stick to 5k oci.

Sample#1 - Dec 2010 = Amsoil SS 0w30 - oci 17,000 miles
Sample#2 - Dec 2011 = Amsoil SS 0w30 - oci 18,700...

I'm backtracking a bit on my TBN position lol. Someone pointed out today how Tooslick would say once TBN is under 4 (approx) that you may see a drop in cleanliness. I do wonder if HPL's very strong TBN, or any oil with high stable TBN, does in fact keep engine cleaner.

Detergents/dispersants are what keep things from sticking to metal surfaces.

You could easily double your interval here, maybe more, but I understand your thinking.
