They are designed to withstand the high temperatures and pressures found within modern engines without breaking down or losing their lubricating properties. A synthetic 0W-20 maintains a consistent viscosity across a wide temperature range, ensuring protection during summer heat as well as winter cold.

This specific viscosity is significantly thinner than traditional 5W-20 or 10W-30 oils, allowing it to reduce drag on the crankshaft and internal moving parts. In hot weather, the synthetic formulation resists thinning (shear stability) to maintain a durable lubricating film between metal surfaces.
In frigid climates, the low winter rating ensures that the oil flows almost instantly upon ignition, reducing wear on the engine during the most stressful moment. Therefore, consulting the vehicle’s owner manual is the definitive method to confirm compatibility before purchasing a product available at Walmart or any other retailer.
