Decoding the Numbers for Engine Protection The numbers preceding the "W" describe the oil's viscosity at 0°F (-18°C). If the oil is too thin at operating temperature, it will fail to protect the bearings and camshaft.
High Temperature SAE Oil Performance and Engine Protection
This measurement ensures the oil maintains sufficient thickness to prevent metal-to-metal contact when the engine is under full thermal load. These formulations utilize polymer additives to provide the benefits of two different viscosities in a single product.
The lower this number, the easier the oil pumps through the engine block, reducing friction and improving fuel economy during cold starts. A low number indicates a thinner oil that flows quickly at startup, reducing wear on cold components.
High Temperature SAE Oil Performance and Engine Protection
Consequently, selecting the correct SAE grade ensures optimal engine protection, fuel efficiency, and longevity. Utilizing a viscosity that is too low can lead to increased oil consumption, bearing wear, and sludge formation.
