The number after the dash indicates the oil's viscosity at 220 degrees Fahrenheit, reflecting its stability and thickness when the engine is hot. In reality, using an oil that is too thick for your engine can lead to poor fuel economy and inadequate lubrication during cold starts.
Decoding the SAE Code: Understanding Oil Viscosity Ratings
Understanding what does sae mean oil is essential for anyone who owns a vehicle or manages a fleet. While the SAE standard defines the physical properties of the oil, vehicle manufacturers determine the exact specification required for a specific engine.
As manufacturers push for greater fuel efficiency, the industry moves toward lower viscosity oils, such as 0W-16, which reduce drag and improve mileage. Conversely, cold weather causes oil to thicken, making it difficult to pump through the engine.
Cracking the Code: Understanding Your Oil's SAE Rating
These oils utilize polymer technology to provide the benefits of two different viscosities in one product. Matching the SAE rating to your specific conditions is the most effective way to extend the life of your engine.
