Driving Auto Performance Through Lubricant Selection

Underhood temperatures are gradually rising as aerodynamics dictate tighter packaging and large engines are being replaced by smaller turbocharged and supercharged engines for improved fuel efficiency. With ambient temperatures under the hood exceeding 120 °C (248 °F), finding a lubricant that can withstand the high temperatures for an extended period of time is key.
