What is the Recommended Engine Oil for my Vehicle?
Viscosity measures the thickness of the lubricant and is not an indicator of its overall quality; a higher viscosity simply signifies a thicker oil.
These lubricants are categorized by Society of Automotive Engineers (SAE) classes, which define how the oil performs at various ambient temperatures. In modern multi-grade oils (such as 15W-40), the rating provides two key pieces of information:
- The Winter Rating (e.g., 15W): The number preceding the W (which stands for winter) indicates the oil's flow characteristics at sub-zero temperatures, which is critical for reliable cold starts.
- The Operating Rating (e.g., 40): The second number represents the oil's behavior at 100 °C under high-load conditions.
While multi-grade oils are the industry standard, you may use an SAE-equivalent oil if the specific recommended grade is unavailable.
Risks of Non-Compliance
Utilizing fluids that do not meet the defined specifications may lead to the following complications:
- Mechanical Damage: Potential component failure that may not be covered under the vehicle warranty.
- Starting Issues: Extended engine cranking periods, particularly in cold weather.
- Environmental Impact: Increased vehicle emission levels.
- Performance Loss: Reduced engine power and diminished fuel economy.
- Safety Risks: Compromised braking performance.
For the recommended oil specification, please refer to the Engine Oil Capacity and Specification section in your Owner's Manual or contact the Ford Dealer for further information.
