Conventional oils have a tendency to change in extreme heat. Your vehicle’s high operating temperature combines with the summer heat to create even hotter conditions. As a result, conventional oils evaporate and lose helpful additives. They may lose important lubricants and additives that help your vehicle stay cool. Your vehicle’s oil consumption will also be raised because of the quicker rate at which conventional oils evaporate. The viscosity of conventional oils will also be affected and can cause the oil to flow less fluidly. Sludge and buildup can cause deposits in your engine that can cause wear and affect your vehicle’s performance.The makeup of synthetic oils allows them to remain fluid in the heat. They are more heat resistant and will retain their viscosity under extreme conditions. They won’t evaporate at the same rate as conventional oils assuring less oil consumption. These oils will cause less deposits, allowing your vehicle’s engine to run smoother for longer. Important additives won’t be lost and will help create less pressure and wear on your engine.
