OFFICIAL: Oil Analysis Report Thread ONLY

No analysis has been confirmed as resulting in failure yes. That doesn’t mean seeing a good result doesn’t point to the opposite because to my knowledge (which might be limited) no positive result has had a failure either. All things being equal, a good result has to at least indicate a better chance that things are going well.

 

Fair enough, but I have my doubts, based on the evidence.

I'd like to see just one poor oil analysis that conclusively signaled an imminent engine failure. Until then, I'm not going to waste my time and money on a mostly meaningless exercise.

But that's just me.

 

I change my oil every 1000 miles for piece of mind.

 

peace*

 

Yes, we all are. That's why we're testing and waiting whose engine will crap out first so just maybe we could see the pattern from the oil analysis that could potentially predict a failure

 

I have a feeling that this particular failure has a quick on set and probably has no bearing (excuse the pun) on your oil change intervals (5K vs 10K). So an oil analysis done before a failure occurs won't necessarily pick up an imminent failure.

If it does then what percentage of what compound found would be considered the triggering indicator?

 

Been following this thread, but just encountered a weird thing. After i saw it i don't know if one can trust all those results unless it has a good explanation



The results are VOA were taken from BITOG. VOA
Also i noticed from reports posted by some users on Toyota 0w20 oil the Moly, Zink and such in used Toyota oil are higher than in VOA

Is it normal?

 

Maybe explain what you think you are seeing.

 

Is an Iron Maiden fan I see

 

We don't know until proven one way or another.

If we get engine failure and no pattern nor hints of it in the oil test results - then yes, oil testing is useless.

But if we see increased metal wear levels, other warnings signs from the oil analysis and the engine blows up - that could be very beneficial information for the ones who choose to not do the recall yet.

 

Maybe I'm wrong but with all the people doing oil analysis has anything significant come up so far? I think this engine failure is equivalent to a brittle fracture. It just happens all of a sudden without any or very little pre-indication of a failure. An oil analysis would have to be done almost immediately prior to the failure occurring and the odds of that happening are remote.

 

LOL, Blackstone is making a killing off you guys.

 

Guy with a nine day old $60k truck talking about spending $45?

 

Take that bullshit oil report to the dealer and tell them your metal wear levels are high and demand a new engine? LOL

 

Blackstone and other companies that do oil testing has been doing this for quite a while and have a lot of customers so there must be value in their service. We don’t know what to look for or even if signs of imminent failure will show up in an oil analysis, that is true. That is what this thread is for I believe. We are trying to figure it out in a way where we use actual measurable data instead of speculation. Yes, there is a lot of people doing oil sampling and don’t have an answer yet, that doesn’t mean we won’t get there. Just ignore this thread if it doesn’t make sense to you. We are discussing data points here, not the validity of the exercise.

 

I think I will stay on and monitor this thread. As a mechanical Engineer with over 38 years experience dealing in all sorts of areas including failure analysis this topic intrigues me. I don't want to be confrontational here but data collection and the analysis/manipulation of that data can be a means of proving that a theory is accurate or not. It will take more than one data point (or a single oil analysis) to do this by the way. Personally at this stage, I am just not so convinced that the the oil analysis data will provide that evidence unless many oil samples are captured just prior to the moment of engine failure. As for the money spent by those who wish to continue getting their oil analyzed that is their business not mine. Just being practical here and would rather spend my money on oil changes or to put fuel in the tank.

 

Or hookers and blow.

 

I agree. I don’t know how many 3rd gen members get oil analysis and post them here. Or get the analysis and don’t post them. Either way, the fact that we do not have an oil analysis on a motor that ended up failing, has to at least point to the fact that failures are not as common as some suggest. And having one oil analysis from a failed motor would probably not prove anything but at least it would give us a starting point or indication what to keep an eye on. I think this thread makes more sense than a lot of others filled with nothing more than speculation and anecdotal “evidence”. People do analysis on motors from different vehicles, heck, even 2nd gen guys do it! So in my mind, it’s not just for the sake of finding out if a sample could predict chances of this particular recall related failure, but also just knowing if the motor is running where it should be.

 

FIFY

I'd agree with you but recently i started doubting the validity and accuracy of their results, See my post #248 above, let alone if you compare VOA of blackstone and other companies for the same oil, they are all over the board.

Thanks for sharing. Nice numbers. Oil Brand??

 

I'm not sure, Toyota dealership special. I think they use m1

 

125k currently on Jan 2022 purchased SR5 with TRD OR factory upgrades
Did BS analysis at 120k
10k OCI (3 yrs & 12 total oil changes)
Using 0w20 toyota flavor
Doing it again at 130k with TBN

 

Thank you for posting.
You say you use Toyota oil? Mobile1?

I compared my results and yours.
Your engine has 100k miles MORE than my engine.
I changed my oil at 1k, and every 5k miles
You change your oil every 10k miles.

How is it possible that your results are same or slightly better than my engine that has 100k miles less and gets oil changes twice often than yours?

 

Wild stuff, huh?
We should grab a beer next time I'm in sf & chat it up....but staying on topic--->

I was nervous at first doing zero early preventative oil changes & going 10k OCI rather than 5k...so far so good

 

Easy answer, see post #259

 

My take on this....gen3 peeps need to drive more & not worry, that's why we got a Yoda, right?
When you hit 100k, then start all the maintenance & analysis stuff

That's what I did & I am running strong
I did the oil analysis at 120k for shifts & giggles....hehehe

Nothing was wrong, but i thought it'd be fun to see what up & make a thread about 10k OCI & higher mileage on an early gen3

Need some new rear shocks & rear brakes soon
(Factory originals at 125k)

 

I'm also doubting the Blackstone results.

Engine with 20k miles and 5k oil change intervals can't have same results as an engine with 120k miles and 10k oil change intervals.

 

If you think about it, it actually makes sense that a motor that spends more time running at optimal operating temperature will have less internal wear compared to a motor that does shorter trips and spends less time, percentage wise, at optimal.

I am assuming, since there is such a vast difference in the mileage on your vehicles, that this could be the case. Not trying to start an argument, just pointing it out.

 

Totally agree with your logic on this
Motors last the longest when regularly used & occasionally driven hard

also, Could using toyota oil (like what was in the motor from the factory) have an effect on the oil test/engine wear?
I noticed that most peeps in this thread are using a variety of oils, usually introduced immediately after purchase of their tundra or soon there after....I didn't touch my factory oil until 10k & only used toyota 0w20 for my 12 oil changes, (btw I did all the oil changes at home)

I'm pretty sure when toyota engineer's/develop motors, they only use Toyota oil with the same specifications each time.... they are not using mobile 1, then pennzoil, then castrol, then toyota


They would use the same flavor repeatedly to insure valid testing results on the motor
Which I would assume is the toyota branded oil....I know toyota doesn't make oil, but using the same oil makes sense for scientific/engineering purposes

Honestly, I don't think any of this is super important but BS probably getting lots of gen3 tundra oil samples!

I just drive mine & enjoy the Yoda life
I did the oil test to see if my motor was due to fail recall wise, not because I was worried or I felt something was wrong with my motor

Knowing that I'm in good shape with my motor gives me the confidence to keep on racking up the miles & aim for 500k if the Yoda gods allow
