What’s the history of OCI’s? Time, distance and oil used? I’m curious how the engine got that dirty in 65k? Thanks for this post.
Valvoline R&P 5W-30, 5k mi; 2019 Lexus RX 350 with 65k mi

Like to know a bit more from the OP about engine noise, low end torque capability and fuel mileage vs previous product installed and run. These are just a few additional factors I use in making an oil choice.

Where are you seeing an engine that got dirty in 65k miles?
Yep. That prompted me to buy the last model with this engine: 2025 3.5 ES 350 F-Sport
Well….look at the mileage in the UOA and the filthy filter.
We have a 2015 ES350, and may end up with a 2025 simply because of this. Really don't want something without the 3.5L V6,
So is this perhaps the best UOA bitog has ever seen?
On worn in, non V8 engines you will likely see total wear metals at 2ppm (+/- 1) per 1000 miles with a good oil choice and interval with frequent long trip usage. I am too lazy to gather the data, I am sure someone in the forum has this handy.
The total bore swept area and the sump volume cannot be ignored and should also be a normalization factor in the calculation though.
A 1.5L 4cyl with a 5 liter sump will likely show better results than a 5.7L V8 with a 5 qt sump!
I just have never seen a UOA with this low of wear metals
Did you see my post #18? on a Frakenbrew?
Don't forget to do the math: total of wear metals / k miles
and that simple math is still not accounting for bore swept area (engine size) or sump size.
... or wear metal in the filter or sump not "seen" by this analysis.
Do not be mislead; UOA in general ain't "All That"

The only thing that UOA tells you without conjecture is that 5,000 miles on that engine in those conditions was too long for that oil to stay in grade. Any other superlatives gushed on this oil, there’s no evidence that other oils with the same certifications/approvals wouldn’t perform statistically identically, especially considering this family of engines is known to be very easy on oil.
Single digit ppm variations are literally noise, think of trying to find Waldo standing in the middle of Tokyo.
Doubtful, since a UOA truly only tells you if the oil itself is still serviceable.
Take a flip on the other (non-Swifty attitude that some folks seem to have for VRP) side… if someone had an engine with a known problem, like an already-spun bearing or worn timing chain tensioners, and poured in new oil and then 5k later did a UOA, is it the oil’s fault that it picked up the material from the previous damage? No.
Dont worry bro no ones gonna take your HPL
Fair enough, but it's not just this UOA. There aren't a ton of VRP UOAs on here yet but those that are posted are consistently showing excellent wear metals normalized by mileage.
It may not prove that VRP is better than something else for wear protection, but it shows it's not any worse within the sample, and you aren't giving up wear protection to get the cleaning.
That is the key takeaway here. It's that VRP is giving you the cleaning without giving up wear protection. And the weakness of that argument being based on oil analysis is the same weakness shared by any and all assessments of wear protection based on UOA, so it's not dispositive.
I was also paranoid the first time I used Valvoline R&P and cut open the oil filter after 1,500 miles to check… found a perfectly clean oil filter.
Been running my typical 5k intervals since. Oil filters still clean after 5k as well.
195,000 miles on my GMC Acadia that has been running Havoline Pro-DS @ 5k intervals for the past 100,000 miles.
The posts of clogged oil filters are from neglected turds that are obviously being cleaned out. Your average engine shouldn’t be THAT DIRTY.
True, however I'd say that most people (in other words non-BITOG people) I encounter don't care about oil or oil changes and either follow OLM or go further. This is why I'm cautious about buying used cars.
I didn't post anything about the filter. The engine has been well cared for over the 65K miles with 5k OCIs using quality oils.
The UOA states fuel dilution is "<0.5" which basically means none or very low. Also the Toyota 2GR is not a straight direct injection engine. It has both DI and port injection.Vis drop is prob from fuel. Looks great. Great low wearing Toyota engine.
This is the only thing about VRP that concerns me. It tends to shear down to a 20 weight. 5W-30 should be in the 10 viscosity range.
B/S labs can't measure fuel accurately.
