GENERAL BRAKE SYSTEMS DIAGNOSIS
The oil service rating is critical to your engine’s performance and protection. Be sure to follow your vehicle manufacturer’s recommendation for the correct service rating.
Exposure to high temperatures over an extended period of time will cause the structure of the oil to break down on a molecular level. This
break down will reduce the viscosity of the oil (increasing heat and wear through friction) and causes the oil to become more acidic, leaving
the engine components exposed to corrosion.
