Scubpar,
the last sentence in your oil analysis indicated "no notable fuel was found" , how does a smell from the oil equate w this lab comment ?

 

That's because when submitting the sample I asked specifically about the fuel smell/dilution in the oil. I paid for the additional TBN analysis which checks for fuel and other contaminants.
I suppose the fuel dilution is still under acceptable parameters.

 

If you want good measurement of fuel dilution, do not use BlackStone. Use Oil Analyzers instead, they have more accurate process to measure it. You can find more info on BITOG

 

Do you have any specific link or reference that you can post here? I did a quick search for "Oil Analyzers" but the site leads to an external AMSOIL link. Also on the BITOG most references are to BlackStone labs. Anyway, I'll keep searching tomorrow. Maybe I'll sent my next 1yr sample to both labs to compare.
Thanks!

Edit: Looking at the The Motor Oil Geek videos I found he uses a lab called SPEEDiagnostix. It's a little more expensive than BSL but couldn't find how it differs on the fuel dilution analysis.

 

here is one

amsoil is just their market place, the lab is called Polaris, or marketed as Oil Analyzers at amsoil

 

Having worked in the clinical reference lab business for more years than I care to mention, I can tell you that there are so many variables in getting a final result that most folks have no concept of what goes into a final result on a piece of paper.....
Just to list a few....
what are the qualifcations of a lab "tech" running the test, what is his/her training and do they recognize an issue if one surfaces with the test while runing it.
what certification standards does the lab operate under
how often is preventive maintenance peformed on that instrument ? how often is the instrument used in the analysis, in this case, mass spectrometers etc calibrated ?---Once every 10 samples, once a day, once a week etc?
How often is a quality control sample run in a batch of specimens?
where is the calibrator or standard that is used for the analysis produced ? Is it made in the lab and if so how is it prepared? How long is a calibration on an instrument good for
Etc etc etc
I can tell you that given the day, who analyzed the sample, where the sample was in the entire test run etc, the results can vary much more than most people think, and , variance is acceptable up to a point based on the standard deviation built into the assay/test
Sorry to bore you all, but results can vary from instrument to instrument in the exact same lab testing the same sample...a sample sent to one lab vs sent to another can vary and its within acceptable limitations
Best bet for you to get a real comparison of sample 1 vs sample 2 is to collect the samples you want compared and send them all at the same time to one lab and ask them to run the test on the same batch.....Thats of course assuming there is no degredation of the sample over time and considering storage....
Enjoy the day...

 

Lab results have their place, but as Lexicon1 explained above...the data is suspect. I'm going with my senses...sight (seeing fine glitter in used oil at 500 miles), and smell (smelling fuel in used oil as it is draining) to guide me. These two things make me want to do a couple more oil changes prior to the "complimentary" change at the dealer at 10K miles. Too, because of the glitter, I'm questioning the ability of OEM filters to filter out the finest of the break-in wear particulates. I'll report back on the glitter after running another 1,000 miles with the K&N filter, HP-1003, in place.

 

Friend, I own a ES300h 2024 - it's an engineering marvel! I prefer to buy brand new for reasons such as you mentioned. More to the point, modern motor oils are super well-researched and developed and will last a long time (maybe even forever??) Strange no record, I agree, but for me it would not be a deal breaker on such a great make and model. Could you use it as a bargaining point? And your engine will not blow up because of a missed oil change or two. Best wishes to you!

That's what I thought. Thanks!

Agreed 100%! Also, after doing some research I don't think the "Fuel Dilution" will deviate much when reported as < 0.5% by BSL. Maybe there's more variance above 1-2%. Analyzing Fuel% appears to be complex and could require fresh oil to compare. This is a note from Oil Analyzers regarding their GC test obtained form BITOG: "When the oil's viscosity is lower than one (1) cSt from the known starting viscosity of the oil when new, we will confirm fuel dilution by ASTM D7593 GC method, reporting the result as percent by volume. However, if lubricant grade is not included with the sample, fuel dilution will be confirmed by GC if viscosity is below 13.3 cSt for diesel engine oil and below 9.8 cSt for gasoline engine oil. If viscosity is above the oil's mid-point for the grade, fuel dilution will be reported as <1.0%."

Nice idea, could be interesting if there's variance in metals reported. Will think about it at my next OCI.

I did not visually inspected my first oil change; but probably would have showed the same glitter under sunlight. Fuel smell on the dipstick was a very faint one, nevertheless was there. You are doing great. Waiting for your report at 1k,

 

Now we can see how many 3.4 bi-turbo turbo engines are failing because of the machine debris that is left inside the engine. That debris gets inside the filter and clogg it and because of the low pressure the main bearings fail. Toyota is recalling 100,000 Tundras and LX 600s.
Also, the first versions of 2.4 turbo had similar problem. I bet you any money that replacing the oil after 1000 miles would solve this issue.

 

With that many clogged oil filters, don’t you think Toyota would have been on top of this a long time ago? That’s a lot of wiped out engines, no?

 

Some of the debris may be left behind after machining, but a lot of fine metal particulates are normal byproducts of engine break-in, which could also either overload the filter or simply not get filtered out because OEM Toyota filters are not good with fine particulates. This is why an initial change at the manufacturer's recommendation of 10K miles seems ludicrous.

 

The debries that can get through a Toyota filter can’t do any harm to the engine. I am talking about the visible pieces of metal that can clogg the oil channels inside crankshaft and clogg the oil filter.
Some of them may cut the paper inside the filter.

 

Just had my 5K/6 months done today. They aso measured the brake pads, washed the car and vacuumed out lots of dog hair!
But agreed, kind of a waste of time for the most part.
