In summer, it resists thinning and maintains adequate lubrication to prevent metal-to-metal contact. Understanding 0W-20 Viscosity and Its Importance The "0W" in 0W-20 refers to the oil's cold-flow viscosity, while the "20" indicates its thickness at operating temperature.
The advanced formulation helps protect turbocharged components and variable valve timing systems, which are common in today's fuel-efficient vehicles. Compatibility with Modern Engines Many modern vehicles, including popular sedans, crossovers, and compact cars, are designed with tight internal tolerances that require low-viscosity oils to function optimally.
