Be prepared for the "lazaro speech"!!!!!!

What you "find....stupid" doesn't really count. Not when there is 30+ years experience in extended OCI's. BITOG is not the world. And 25K in a vehicle is not "testing ground". "Tall claims" they may be in your mind, but I can say they are more than just claims.

So we can brag on UOA's for lower OCI's, but if this UOA is OK, we should ignore it. Doesn't make a ton of sense.

If this UOA comes back healthy I'll be the first one to sing the praises of amsoil, as I've done many times. I just don't think it's going to happen with a new engine and such a long oci. We'll have to wait and see.

Lazaro, don't fudge the numbers eh! Give us the real goods when they come in

35 years of testing is a testament to quality product, My dad has a 2006 Toyota Sienna van with over 118,000 and we have done 4 oil changes so far total cost $260.
Are you saying we are

lazaro, very few UOA's look good with any synthetic oil past 15k miles.

 

[dave123]

Most run under 10k or less big deal... for something to go 25k to35k

 

[Brons2]

So where are the much balloeyhooed results?

 

[lazaro]

I have been waiting for the results online at http://www.trackmysample.com
The oil sample was recieved but not tested yet, maybe another few hours,days,weeks?
real soon I bet

 

[buster]

Will you have a Tbn with this sample?

 

[lazaro]

results are in as I promised, you guys should have a field day with this! 40 miles to 25,856 miles 5.3 gas engine.
I did cut open the oil filter and the pleats, after cutting away from filter and squeezing out excess oil, were free of any large pieces of metal or free of any sludge, but the results are significant
Aluminum 12
Chromium 4
Iron 132
Copper 332
Lead 141
Tin 10
Moly 79
Potassium 7
Silicon 70
Sodium 45
Calcium 307
Magnesium 18
Phosphorus 614
boron 30
Zinc 782
cST Viscosity @100 14.5
TBN 2.76
OXIDATION 57
NITRATION 45

why would I fudge the results? I dont swing that way. you mean you know people here who do?

CLOSE!

 

[webfors]

this may have been covered already, but what viscosity/product from amsoil was used?

My guess? Copper over 300, Iron between 100-150, Lead around 30-40, Silicon around 200, viscosity well into the 40-weight range...

But engine will probably run fine right to 200k!


I came pretty close, except for the silicon and lead. The lead would trouble me, as even at break-in, lead is much lower than iron. The fact that it is higher than iron here means there is some abrasive wear happening to the bearings.

I'm impressed that the oil still had some TBN remaining - I think it is a good showing for Amsoil in an almost impossibly difficult situtation...

Webfors,

Amsoil ASL 5W-30 was used.

Couple of other observations - I'm assuming the Calcium number is a typo, and is really '3007', and I'd assume that the sodium is left over from the Mobil conventional factory fill.

I wouldn't treat a new vehicle this way, but heh, each to his own!

your right I read the calcium wrong it was 3078

We did not find any results for balloeyhooed.
Search tips:
Ensure words are spelled correctly.
Try rephrasing keywords or using synonyms.
Try less specific keywords.
Make your queries as concise as possible.

 

[Drew99GT]

Oxidation and nitration, along with viscosity, are up there. No insolubles?

All I can say is, thank goodness it's not my truck!

For what you spent to do this oil change using the Amsoil filter, and getting a UOA, I would have done 5 oil changes with a conventional oil, or even less and followed the OLM so my warranty wouldn't have gone down the craaper. A 100,000 mile powertrain warranty isn't something you want to chance.

But to each their own I guess.

Pb 22 141 actual (really wasn't expecting lead to be this high)

Si 111 70 actual (eh, close...)


I wonder if high levels if normal break-in copper would be abrasive enough to be the cause of the iron and lead levels? Does anyone know if this engine type normally throws off copper early in its life?

With the "wink" emoticon I think webfors was saying this 'tongue in cheek'...and now that I think maybe your reply was also!
