I put in Castrol Magnatek 0w-20, purchased in Feb. 2022, from the stash. SP, dexos 1 gen 2 on the label. Which I came to find out has been discontinued. I'm not a big believer in oil shelf life, correct my wayward thinking if needed. The poor old Mazda commuter gets all the older stuff now.

Ugh. I ran this way too long by mistake, typical is 7500. Had to see the carnage. It was a roughly 50/50 mix of K&N and Kirkland, both 0w-20. First time I've used Oil Analyzers, have always done BL in the past. No cross ref of ranges and no commentary I see. Please give your read on the report.

I was busy with work and duties and didn't email Blackstone until Wednesday the 29th. I received this in reply: ------ Unfortunately, we only keep samples for a week after they're tested, so we no longer have this sample of oil. It's not unheard of for iron to read low in this kind of engine...

I will contact them. Lot of wisdom on this board and the iron argument is compelling. And if there is material left for a retest, might it be useful to add the TAN test? Further, might they release the residual and mail it back, to send to another lab? This is such an unusual OCI and it would be...

What an ... waste of time and money if so. I was getting mad at how long it was taking. I drew on the 27th iirc, mailed the next day iirc, and didn't get results until Jan 20? Even excusing for the New Year's delay. What's the issue with their fuel dilution testing?

I do remember back in the day people here were complaining about Blackstone numbers getting wonky. I see now, not having posted in a few years, a lot of different testing companies. Is Blackstone still considered accurate and reliable? Considering this was a one-off run, I would have sprung for...

Not on the run after 26k. The engine is running the "after" right now. I changed at 115k down in AZ, changed at 141k at Christmas at my home. I'm a Bitoger since 2005. Green GC days. I'm surprised at the doubt of my word. But I guess that's the territory of today's more suspicious 'net...

Dang, I would have done a TAN. I see it on their website, but don't recall the option on the tiny order sheet.

I don't recall TAN being an option on the small check sheet when sending in. TBN was the extra $. Correct, no makeup oil. My relative is not a maintenance guy. The oil was down about 3/4 qt. Know the 4Runner specs 0w-20, but I had put in 5w-30 given he lives in Arizona, drives long distances...

I tossed the filter at the time. The 4Runner uses a non-can unit, would have been easy to lay open. It was either a Fram Ultra or SE, as at the time I expected a longer OCI. I can assure you this is real info, but that means nothing obviously. I don't understand the "averages don't track." Does...

I changed this oil on a relative's 4Runner last spring. He ran it 26k mi with a lot of long distance driving. On his visit this Christmas, I changed it again. Horrified at the OCI, I ran this test, to see the carnage. I haven't run a test in a few years, oil is so good now it doesn't really...

I'm a bit committed to the 0w-20 flavor of SGT now. Picked up 30 quarts in the ongoing Autozone clearance. Ends up $0+tax after rebate ($0.20/qt) net. Going to run this in a DI Mazda 2.0. SN+ and dexos1/gen2 should do fine. Higher moly is in keeping with Mazda's own oil as well. Otherwise...

Ran this test to check engine condition more than anything, as I bought this Jeep with 120k on the clock. Have run it to 130k and had 5k on this OCI. Post this test, I'm running high mileage M1. Highest 100C cSt I had in my stash, as I've read the 4.0 prefers heavier grades. Though I've found...

One of my previous UOA posts, with 3 oils compared in the same engine: here Results below: QSUD = Quaker State Ultimate Durability, MS = Mobile Super 5000 Code: OIL Chev 5w30 SN QSUD5w30 SN MS 5w30 SN MILES IN USE 6500 7400 5700 MILES...

From a 2007 Subaru Forester 2.5 naturally aspirated with 162K. I ran the oil to 8050 miles not by choice. I was a bit derelict in getting it changed. I had the external infamous head gasket leak and both HGs were replaced at 125k. This was my first UOA after that work a few years ago. This run...
