RAV4 Hybrid with 40,162 miles. Is a DD and driven very easy. Good mix of trips less than 10 miles and between 11 to 40 miles. 80/20 split local/highway.

Changed oil and oil filter April 2020.

Filter was Purolator PBL 25608 and was in good shape with no noticeable particles to cause concern nor build issues.

Seems the Castrol Bio-Synthetic held up well in the 2.5L (2AR-FXE)

And yet another great Toyota 0w-20 UOA. I’m not surprised.

Thanks for the used oil analysis-ten looks great and overall can not beat Toyota engineering-excellent oil analysis and great wearing engine.
