Question Oil Analysis

Posting in General, please move to mechanical if needed.

I will be sending off my engine oil to Blackstone Labs in about a month or so when I do our next oil change. It will be 1yr and ~10k miles since the last change, which was the first change while we have owned the vehicle. Please don't criticize me for that, it was not my ideal circumstance to do the first test after we put 10k miles on the engine and oil... life gets in the way some times ;-)

I'll post all my results here, I have no real concerns that a modern engine in good condition can easily do 10k miles on synthetic oil. I'm simply looking to find out if our engine is good or was it abused before we bought it.

I have two questions.

First, has anyone done oil analysis of the transaxle/transmission fluid on their RAV4? If so, can you share the details (age, mileage, etc... at test) and the results?

Second, has anyone collected engine oil analysis done by the forums users? I'd love to review what others have found in their oil at various points along the life of the car.

Cheers

My OCD is getting the better of me... I am building a spreadsheet with the various RAV4 Oil Analysis results I can find... Please share with me your results if you are willing (PM for e-mail if that is preferred)...

Here are a few for you. I discovered the motor and oil do just fine with 10,000 mile oil change intervals.

Same goes for Mobil 1 0W-20 Advanced Fuel Economy oil.
