Ok. Are the numbers you provided all there was to the analysis?

Have a JATCO in an 08 Rogue with 120K mi on it. Love it, wouldn't trade it. The only issue I see is it got a little noisy but that was fixed with a fluid change. I service it every 60k. I used Eneos CVT fluid and the CVT has always been quiet since. I think a lot of the noisy units that were...

OP, Is the drum not labelled? Do you have any other info from the analysis that can be posted? Was there any Zinc or Phosphorus in the oil? Thanks,

ccl088, I see nothing of concern in your analysis. Use it as a frame of reference or "starting point". As others have suggested, there are two many "ifs" to draw any real conclusions, especially alarming ones. I see nothing that would cause me any concern-yet. As some others have suggested...

BlueOval, Here is an article that addresses changes for GF-6. IIRC, this has just been delayed to Jan 2017. I already have enough GF-5 on hand to get me there lol. http://www.stle.org/resources/articledetails.aspx?did=1671

Still looking good, harryj! How's it looking under the valve cover? Can you see much through the oil fill hole?

Thanks for posting! Can't get enough "under the valve cover pics"!

Napa has them in the Carlyle line. I've had good experiences with their stuff so far.

Merry Christmas to all! God Bless!

Congrats on the car! I have been privileged to care for a small fleet of these cars over the years and I will miss them! What an awesome fleet car! I have always run Schaeffer's 7k 5W-20 in ours with 10-20k mi equivalent drains and they run like tops and are spotless inside when we part with...

Looks good!

Thanks, I think so too. I have been using Schaeffer's in our small fleet for several years now. I will try to post up some more right off.

Thank you! May God bless you all!
