i think its a pretty uneventful looking report, seems most 4runner engines don't want to do anything
but run. That said, I've been running M1 0W-40 in mine for years now and I think you'd be hard pressed to beat an oil of that thickness when its ~$25/jug down at the local wally world.
here's my last UOA, just food for thought - my iron levels were a bit lower by 20k miles although i'm sure its practically statistical noise at that level, vehicle to vehicle.
glad you like the truck, i love ours! just turned 55k miles, looks basically new inside and out, and asks nothing of us aside from fluids.
