Mobil 1 Toyota 0W-20 oil analysis in Insight hybrid

If I recall correctly, the G3 was the first Prius to switch from xW-30 to xW-20 oil. Here is an oil analysis I did comparing Mobil 1 versus Toyota's own oil (in a Honda engine). The Toyota oil performed just as well as the Mobil synthetic (except the T oil had high acid content):

Mobil 1 0w-20 on the left
Toyota 0W-20 on the right
1.0 liter 3-cylinder, 2006 Insight hybrid
4000 mile intervals, 134k on engine

BLACKSTONE: We like steady wear trends, and they don't get much steadier than this! We always say that it takes three samples to build a solid trend line, but the first two reports show nearly identical levels of wear after similar oil runs, so you're off to a really good start for this Insight. No moisture, dirt, or fuel was detected, so the oil was once again free of harmful contaminants, and there were no signs of air or oil filtration problems (low silicon and insolubles)

Same Honda car, but two different oils in two changes.
