5w-50 Roush/Valvoline Blackstone OIL report
- Thread starter me32
- Start date
Yet another virgin sample with extremely low levels of ZDDP.
It frightens me.
aww man, you didn't pay the extra cash for TBN readings. I would have loved to know how much TBN, or little actually, was contained in the sample. Thanks for doing this though, we needed this information.
Like I have been saying, Blackstone FTL. OAI gives you TBN and oxidation readings for no additional fee.

Has anyone sent in Castrol Syntec 5W-50 for analysis?
There isn't a VOA that I know of, but there is a UOA. You can read about it by clicking the link below.
Castrol 5W-50 UOA
After reading all this I will be changing out my Castrol w/ K&N filter asap. I'm not sure if it will be a good example with my mods and the few times to the track but I have about 1500 miles on it and 5500 total on the car.
I've heard of Blackstone but who is OAI? I can it to them to get the extra readings
API SM maximum allowance is 800-900 ppm, why not max it out to get as much protection possible and still pass the certification?
This is the second VOA sample of 5W-50 that shows low amounts of ZDDP. I wonder if Blackstone is doing something wrong in their testing methods.

Oil Analyzers Inc.
The letter head company name is owned by Amsoil, but all lab testing is performed by Polaris Labs.
You can buy your pre-paid testing kit here.

thanks for the info, when are you gonna send you amsoil in?
I don't believe API SM has an established limit for Zinc, but there is a range specified for Phosphorous (P) and that's between 600 to 800 ppm (parts per million), and only for certain grades that do not include 5W-50. For 5W-50, the only requirement for Phosphorous is that it must have at least 600 ppm with no upper limit specified.
So with 450 ppm P, this sample of oil does not comply with the minimum API SM level specified for P.

The Valvoline/Roush 5W-50 oil complies with the Ford WSS-M2C931-B spec. Perhaps the Ford spec contains limits for Zn and P?
Here is an interesting claim that's certainly not justified by the VOA:
ROUSH Motor Oil is one of the only synthetics on the market using an advanced anti-wear additive that keeps higher levels of zinc/phosphorus in the engine where it can protect the internal components instead of on the catalytic converter (which can actually damage the vehicle's emissions system).

Finally got the Blackstone kit yesterday, and the oil change is taking place tomorrow. The UOA results probably won't be in my hands until after the new year. :nonono:
Thanks for the info, good to know. Looks like this oil, much like the Mobil 5W-50 sample, is fail.
This is a reminder to you all of how marketing can be so misleading. People can be a skeptic of AMSOIL all they want, but every VOA and UOA proves it performs and formulated exactly how the manufacturer claims.
So unleashed your using blackstone. I ordered their kit last week so as soon as it gets here i'm going to do the oil sample for the truck. ordered another kit to do the mustang since i'm running castrol syntec and was planning on going back with castrol
I'm really wanting to know what was in the old motorcraft spec A
I only ordered a Blackstone kit so I can send it to BOTH labs.
I'm tired of skeptics saying OAI is biased towards AMSOIL's, when Polaris labs actually does the testing. If I send a sample to both, and the results come back close....I can put a lid on that debate.
Looking forward to the Amsoil results. That is the brand that worked best for my previous cars with turbos or superchargers. Of course, I found that out by trying several different brands. The Amsoil Euro Car 5w40 was great and designed for boosted cars.
Beast, is there going to be a 5w50 Amsoil or are you going to try the Euro 5w40?
A few things that would be helpful for those posting up a UOA is if they could post their mods, driving style, and climate. A sample from someone with a 4.0 Whipple is going to be different than someone running a stock car. There may be a reason the oil isn't holding up as long as some may think it should...like coming from a 700rwhp car or someone who races. Amsoil, like others, voids their oil warranty for modified cars for a reason...you can't expect it to last 7500 miles regardless of the engine environment and you may need to change it sooner.
Can't wait for the Mobil 1 results to be posted...I am betting they will be horrible like they were under boosted conditions in past years.
I've used Blackstone for my testing but would be 100% comfortable using OAI as well. I don't think either one is incompetent given their business line nor biased. It's a fairly simple business for them given the expertise they have. People like conspiracy theories...

I'd like to see a virgin sample of Motul for S&Gs. Seemed to hold up well during track days in the past.
300 V 15W50 Competition

The Roush/Valvoline 5W50 is no longer available...so isn't this kind of pointless?
Pointless? Captian Obvious says: I doubt it is to the people who still have the oil in their motor or the people who bought some for their next oil change and/or several cases of it. If you have no interest, move along.
