Redline 0w20 15,458miles Focus

^I think you might be right, at least according to 'recommendations'...I'd like to see what Mobil1 5w-20 EP could do instead or Amsoil ASM. 15,000 seems to be too long also, try 13,000 next time.
Also, here is the virgin analysis for this oil. I also put a larger then stock oil filter and compared results with previous microgreen and K&N filter. The larger filter has given better filtering:
Micron particle size and respective counts/ml. Note, first count value represent oem size microgreen filter, second is oem size K&N and third is an oversized mircogreen filters. First and second count had ~12,000miles, whereas, third is with 15,458miles on the car:
>=2: 1085,, 2878,, 833
>=5: 402,, 1066,, 308
>=10: 111,, 295,, 85
>=15: 43,, 114,, 33
>=25: 10,, 27,, 7
>=50: 1,, 2,, 0
>=100: 0,, 0,, 0

Why 13,000? Seems like 15k is about right?

We don't have a TAN here, so assuming a TBN of 1.4 is adequate is risky. I'll agree that everything looks great aside from the lowering FP.
Also, to the OP, I wouldn't worry about the minor up-tick in iron. What's the accuracy of sampling and analysis? I'd stick with 0W-20 and NOT go back to 5W-20.

Variables change etc etc, this appears to be an exhausted oil. 15,000 seen here is about near death, so I'm just offering the advice of perhaps giving the oil and your engine more headroom.

Yes, but with a tight engine, it shouldn't be an issue. I'd rather replace the cat before the engine.

Have you replaced engines before?

LOL! Point taken but I'm a believer in the protective attributes of zddp.

Thanks for the UOA, I don't think you could get much better. I wouldn't switch either, you have a trend going and it is good. This was max though. Tan is hard on this type of oil though. Esters start out with higher acid #'s than petrol oil in general.
The TBN is your guide with this oil IMO. You have hit your max, but it is doing beautifully.

I have some real (to me) concerns about people trying to do extended OCI's and verifying oil condition with simple Blackstone UOA's. Don't get me wrong, I have used Blackstone many times myself. But I understand the inadequacies of the basic with TBN report. For wear trending it works fine. But for oil condition and causes of abnormal wear, it becomes a guessing game. Ordering more testing from Blackstone is a must, or use a different lab that includes more oil condition testing.
Although wear indications and trends remain steady, the oil has thickened and it has more fuel dilution than Blackstone indicates. So with a relatively low TBN, I'd like to know what TAN, oxidation and nitration are to decide when this oil is truly unserviceable. Anytime there is thickening or shearing, a V40 cSt would be nice to have also.
This is only a recommendation, since you appear to be concerned about your investment enough to do a UOA. I'm just trying to point out that extended OCI's are a different animal than just following the manufacturer's recommended service schedule. IMO, getting more information is paramount to doing this safely, rather than getting a false sense of security from a simple Blackstone report.

I wouldn't say that. OP wend beyond a cheap UOA and included particle count.
I did see the thickening out of grade, but this 0W20 started as almost 30 oil, so it's not huge. I kind of wondered how Blackstone determined what should be the viscosity range for used 0W20 oil. They reported it as still in range.
IMHO, despite what people say, this UOA validated 15k miles in this application with this oil.

I don't know, the VOA shows it thickened to me. It starts out as a nice 20 though.

I would want much more info to validate a 15K OCI.
