I usually stop by walmart and pick up my oil, and have found that they have RP in stock. See price chart bellow. I usually use Valvoline since its good value for 5qt which is exactly the amount I need and is almost always in stock. But, would RP be worth it for that 11$ more for 5qt?

FULL SYNTH 5w301qt5qt
Super Tech$ 5.28$ 19.98
Chevron Supreme$ 4.58$ 22.90
Quaker State$ 5.72$ 22.97
Valvoline Advanced$ 8.98$ 26.97
Penzoil Full Synth$ 7.66$ 26.44
Castrol EDGE Advanced/HM$ 8.88$ 28.94
Mobil1 Advanced/HM$ 8.78$ 26.97
Royal Purple HP$ 9.07$ 37.56
Mobile1 Extended Protection$ 9.67
 
It's been a while since I paid any attention to RP. Was never a fan of it. IMO, no there is no benefit.

Their website has some good information on it though. Took a quick look. Their current PDS look decent. Low VI. Probably pretty shear stable.

14% isn't great.

Do you think it would be worth running in a tuned 2.0 turbo engine vs just any regular oil like M1/Val? I am pretty sure it would be of no benefit in any of my toyota's.
 
I used RP in my 2020 Equinox and did a UOA and compared it against Pennzoil PP. the RP had a much better uoa than the Pennzoil. I have Valvoline EP in now and will compare it to both RP and Pennzoil. If it’s close to RP I’ll use Valvoline for awhile and save $ oil change.

Do you have the UOA sheet? Or link to OG post? Would love to see the numbers. I don't see Valvoline doing much better than Penzoil around here in the UOA department, at least for me, I have a decent amount of fuel dilution.

This was after 4k miles of 5w30 valvoline.

'22 Accord 2.0t K20C4 Valvoline High Mileage 5w30 Full Synth 4K Miles

Bought car with 6ish k miles, did an oil change at 8k and now at 12k miles. First drain was factory honda 0w20, second was valvoline 5w30 full synthetic high mileage.

Have a look at their HPS line of oil, not the shelf stuff at Walmart that has to restrict ZDDP levels in order to get an approval.

Nice, but that would be like 2x the oil price from what I pay now. 10$ more is fine, but 25$ more is a bit much considering I change every 4-5k miles (although the argument would be you could go longer, but I wouldn't anyways).

Based on the UOA I saw of the off the shelf stuff, 0w20 has better results than my Val 5w30 LOL.

I don't. I still think M1/PUP/Castrol Edge are as good or better in most areas. I don't know about their HPS line.

Give it a shot though. That's just my opinion on it.

RP was bought by Calumet in 2012. I don't know what role they play, but I know they are a chemical manufacturer.

I buy it in the 5 gallon containers, lots cheaper per QT like that, but I understand it is a larger initial outlay of funds.

Have a look at Mobil 1 Euro 0-40 if you're wanting something you can find on store shelves. I buy that stuff in the 12Qt "garage packs"

agree 👍. The HMX line in 5w30 has a 3.3hths,Synerlec and high mileage conditioners. I believe it's SL rated so lots more of the good stuff. the HPS line is even higher up but I don't know much about it specifically. Used to buy their GDI spray directly, but using CRC,Lucas, etc

Yeah, I did the math on the 5 gallon and its pretty much identical to just buying 5qt's. About 50$ per OCI vs 25-27$. Although I might as well give it a try and see. Only one way to find out.

I think we're talking different things. There isn't anything special about the shelf RP oil at Walmart and IMHO, it is way overpriced. Conversely, their HPS line of oil has much higher levels of ZDDP and can be bought in 5 gallon containers for 178 to your door, or 8.90/Qt, which is half what it costs per Qt in the very few stores that stock it.

RP HPS 5w30 VOA

Here is the VOA i promised of the RP HPS 5w30. Bottle wash shaken well before I took a sample. This oil looks stout. A healthy dose of Calcium, and plenty of Zink and Phos. Does anyone know if this moly would be Trinuclear? Enjoy!

That VOA looks pretty good to me

You can't use UOA's to make this sort of comparison, it's outside the useful scope of the tool.
