Oil needs an ultra-high viscosity index to account for extreme temperatures. The oil must be able to flow when temperatures are cool, and protect in extreme heat. Higher viscosity oils maintain their thickness to better keep metal components separated in the engine under high load at high temperatures. Watch as Lake Speed, Jr., Certified Lubrication Specialist at Driven Racing Oil™, explains how Driven products feature an ultra-high viscosity to handle higher temperatures than ever before in a wide variety of applications.
