Oil changes

By this logic, we should be expecting an increased amount of engine failures past 60k miles. I don't think we are seeing that though with Toyota, Honda or even Mazda vehicles. Also, how do you know that the engineers did not sign off on allowing 0w20 engine oil be used for daily driving in North America?


I agree about the thicker oil possibly offering more protection, but you have to remember, we are driving family cars, not race cars. No one is going to be cruising down the highway at 5k RPM for the whole stretch of their commute.
