Why You Should NEVER Use 0W-20 After 100,000 Miles (Unless You Do THIS)

Why You Should NEVER Use 0W-20 After 100,000 Miles Does 0W-20 become dangerous once your engine passes 100,000 miles? The real answer is more complicated than most people think. In this video, we break down what engineers, oil-analysis data, and experienced Toyota technicians actually say about 0W-20, 5W-30, high-mileage engines, fuel dilution, oil shear, and wear. You’ll learn when 0W-20 is still the right choice, when moving to 5W-30 may make sense, and why oil condition and change intervals often matter more than mileage alone. If your engine is healthy and the manual calls for 0W-20, mileage by itself is not a reason to switch. What oil does your car use, and how many miles are on it? #0W20 #EngineOil #CarMaintenance #HighMileage #MotorOil #MechanicTips #Toyota
