266 views

10W50 and 20W50 motor oils are both good for high-temperature conditions. However, 10W50 is better for cold starts due to its lower winter viscosity rating. It flows more easily at lower temperatures, providing better engine protection right from the start. On the other hand, if you live in a consistently warm climate, 20W50 is also a suitable choice. Always check your vehicle's manual for the manufacturer's recommended oil grade.
