most dealers pump oil out of a common 500 gallon tank.. they use recycled oil, whatever the local petroleum supply sells..

it's crap oil..

but seriously, a 30 to 20 weight change on the high end of viscosity is NOT GOING TO SPIN A BEARING. there has to be another factor that caused the damage.

Why not? This is operating end of spec, And the viscosity is much less. SAE 30 is ~ 65% more viscous than SAE 20. 5.6 vs 9.3 cSt MIN. That bearing wont run out of hydrodynamic range too long before it gets hammerd egg shape at the top center of the top bearing shell, rod big end. Then you have Clack clack clack. Easily predictable failure - ignoramus EPA pushing AUtomakers to show higher CAFE numbers, Stupid managers making stupid decisions. Lucky toyota with the 60K engine warranty. I'll trade car at dealer that ruined it. I'll run 60W race oil to get it there.
