Castrol EDGE Motor Oil 0W8 Full Synthetic 1 qt (US)

Advances in engine technology have led to increased power and efficiency, meaning engines work harder, under more
intense pressure and higher temperatures than ever before with longer drain intervals being recommended by vehicle
manufacturers. These demanding conditions require the motor oil to be stronger and more resistant to thermal and
viscosity breakdown to maintain protection and deliver maximum engine performance.
Castrol EDGE has been engineered to withstand the extreme friction of modern engines and provides 10X better high
stress performance than the latest industry standard. Peak engine loads and high operating temperature can break
down weaker lubricants, so viscosity control is the ultimate measure of strength for any motor oil. Castrol EDGE has
been proven 3X stronger against breakdown than the leading full synthetic, so its shear stable and maintains its initial
viscosity over an extended drain cycle of up to 10,000 miles.
