As your aware from posted UOA's, under the valve cover pics, etc, Toyotas love M1. Toyota may think so too, new engines are designed around TGMO 0w20 which is a XOM brew. My personal experience with Toyotas swapping brews agrees. Use M1 in a Toyota long term, get a long life with no problems.
So which one? IMO both have similar cleaning power, a step above regular M1. For an older Toyota engine would go with M1 HM. The Camry in my sig has some old age issues all caused by rubber seals (burns oil, has several oil leaks). Results of prior owner neglect and sludge. 130k later, I still havent replaced anything. Oil consumption is better, a reasonable 1qt every 3-4k, no oil leaking on the ground anymore. 8-10k OCI's with a high efficiency filter. Thats about 4 months for me. Mostly brutal city stop and go with a few high speed races to parts depots. But OCI length was gradual, the car was a sludge bucket to start. The engine looks like it will outlive the body with no major mechanical repairs.
