So here you go, maybe you are old school and are stuck in the old days. thinner oil carries heat away a lot quicker, less drag and friction, runs lower oil temps. thicker oil moves slower and keeping heat in the bearings, raising oil temps, etc. there is way too many Toyota’s and Honda’s out there running good ole 0w20 especially in tundra with half a million miles on them. There are many 2016 and newer Nissan titans out there using 0w20 with over 200,000 miles on them no issues, whole lot of Nissan maximas out there 0w20 over 300,000 miles on them with the snot ran out of them no issues. Toyota camrys with 200,000 miles using 0w16 no issues. Stop comparing Asian vehicles to garbage domestic vehicles. Asian vehicles can handle the thinner oil. Domestic vehicles can barely make it past 100,000 miles.
