If you have already opened the store, Restore it on your taskbar. Not only does refining fail to remove critical impurities, the actual lubrication and performance qualities of refined petroleum lubricants are limited.
Synthetic lubricants are impurity-free and offer superior performance and greater versatility.
Heat transfer Heat damages system components and destroys petroleum oils. Synthetic oils maintain their integrity in much higher temperatures than petrolem oils can tolerate. In fact, synthetics actually remove heat from lubricated systems, helping them perform better, last longer. Lubricated systems remain clean and efficient for superior performance, long life. Lubricated systems remain deposit-free and corrosion resistant for longer life.
