Castrol EDGE advanced technology
The American Petroleum Institute (API) includes multiple tests to measure a lubricant’s performance. To be certified against the industry standard, the oil must achieve the minimum value of the test limit. Castrol’s line of premium engine oils far exceed these industry standards, ensuring the highest level of protection and performance for your car.
Viscosity breakdown (3X stronger)
Viscosity breakdown in motor oil can result from the mechanical shear that moving engine parts put on the lubricant. This shear breaks the oil down at the molecular level and reduces the initial viscosity. This reduction in viscosity increases the probability of metal to metal contact and decreases the motor oil’s ability to provide engine protection.
High temperature performance (10X better high temp performance)
Castrol motor oil protects an engine in many ways, including prevention of the formation of deposits on engine valves and pistons. These deposits often occur as a result of the extreme internal operating temperatures created during the fuel combustion process. Castrol’s high-quality motor oils clean these critical metal surfaces with detergent additives to prevent deposits from forming even under intense operating conditions.
