Matching Oil to Your Engine Modern engines are engineered to precise specifications, requiring specific oil viscosities to function correctly. Selecting the correct viscosity grade ensures optimal lubrication, reduces wear, and helps maintain fuel efficiency.
Understanding SAE Ratings for Cold Weather Oil Performance
They are engineered to resist thermal breakdown and shear forces better than conventional oils, meaning they maintain their correct SAE grade performance for a longer period. Using the wrong SAE rating can lead to significant issues.
If the oil is too thick (high viscosity), it can cause poor fuel economy, reduced engine power, and difficulty starting in cold weather. Conventional Oil Ratings Whether you choose a conventional, synthetic blend, or full synthetic oil, the SAE rating system applies uniformly across all types.
Understanding SAE Ratings for Cold Weather Oil Performance
The Meaning of the "W" The letter "W" stands for "Winter," and it is a critical component of the rating. This dual-number system provides a complete picture of how the oil flows through the engine's intricate passages.
