The "20" refers to the oil's viscosity at the normal operating temperature of 100°C. The extended drain intervals associated with synthetic formulations also mean that used oil is generated less frequently, reducing the environmental impact associated with disposal and packaging waste.

Decoding the SAE 0w-20 Viscosity Grade The "0W" portion of the designation indicates the oil's flow characteristics at extremely low temperatures, specifically measured at -35°C. An incorrect grade can lead to inadequate protection or, conversely, excessive drag that reduces performance and efficiency.
Conversely, the advanced additives and synthetic base stocks prevent the oil from thinning excessively under high-load conditions, such as towing or high-speed highway driving. Always consult your owner’s manual to verify that sae 0w-20 is the recommended grade for your engine before making a switch.
