Based on my UOW of my last bulk dealer fill in Canada it WAS TGMO based on the ppmThe question is what bulk oil is used by Toyota dealerships? Honestly I don't think anyone trying to drive a car 200-300k plus should really be doing more than 5k, you're spending very little extra money as insurance you won't need a $6000 engine. Nobody ever wore out their engine cause the oil was too clean.
Of moly! The Aug of moly blows my mind.
