    Throwing around non-standard home-made and insider acronyms instead of plain-English equivalents somehow makes some people feel superior. That habit is caused by a combination of laziness and elitism.

    sorry I made you feel inferior :) (actually you did it to yourself )

    But the fact is that this (UOA) IS a common acronym on blogs where car maintenance are discussed. And this is a technical thread of a CAR more specifically Gen 3 prius ... where among other things common maintenance like oil change and other stuff like, you know, MPG, ATF-WS, OCI , CVT etc comes up time to time ....

    After reading these threads, I had the dealer change my ATF at 15K miles, [ after tearing and surgery for meniscus tendon ]. I changed the wife's fluid myself at 55K in her 2012 ''v'' a few months before this, and it was BLACK. I goofed around and forgot my sample bottle when going to the dealer, and have kicked myself for being so negligent. My next oil change, I will get a UOA and my ATF also around 55--60K.

    i consider comments like that a gross exaggeration. now if you had a picture of oil blotted on paper towel, we could discuss it.

    All righty then--- it was a very, very dark brownish black without any hint of factory red/cherry. Better, Thomas??

    Since the original post CANNOT be edited anymore (not sure why it was pretty convenient updating the original post)

    I am putting a table here with all the data as it comes in time..... hope this is useful...

    The newest change was done a little early, only because I needed a state inspection and did not want to go twice in two weeks ... and this way actually the inspection was "free"

    the above (your post IS the updated one) unfortunately the original post is no longer editable I thought it was neat that I was able to add almost 4 year of data .....

    so yes my last post is the updated table (you can see from the dates)

    I thought maybe a thread to collect this information is useful for all. (moderator please feel free to correct me)

    Since the older posts are non-editable. I am quoting the last table and adding to it as it goes

    See bellow the updated report including the most recent data.

    Here it is.

    Since the older posts are non-editable. I am quoting the last table and adding to it as it goes

    See bellow the updated report including the most recent data. Las oil change 21 April 2018 @74650 went a little bit early ... another fill up or two weeks left but better early than late :)

    I am not totally sure about this the service guys gave so little oil half the test couldn't be done, and the oil seems contaminated. Perhaps forgot and filled it from the pan ?? ... and the result is funky ... but I will post it so the record is there



    Here it is.
