  • High mileage formula protects older engines
  • Synthetic blend resists breakdown at 410 Degrees F flash point
  • 10W-30 viscosity flows at -22 Degrees F pour point
  • 9 cSt at 100 Deg C maintains film strength
  • 1 qt bottle fits standard top-off needs

High-Mileage Synthetic Blend 10W-30

This engine oil is formulated for gasoline engines with higher mileage. The synthetic blend base helps protect aging seals and reduce oil consumption. It comes in a one-quart bottle for convenient top-offs or smaller sump capacities. Drivers seeking extra wear protection for older vehicles will find it suitable.

Viscosity limits at temperature extremes

The SAE 10W-30 grade means the oil flows at a pour point of -22 degrees F for cold starts. At operating heat it reaches a flash point of 410 degrees F. Measured kinematic viscosity is 80 cSt at 40 degrees C and 11.9 cSt at 100 degrees C. Specific gravity is 0.86 at 60 degrees F.

Check your manual for grade and capacity

Verify that your manufacturer specifies SAE 10W-30 for the current climate and engine condition. Confirm the total oil capacity so you purchase enough quarts for a full change. Ensure the drain plug and filter are accessible before starting the job.

Questions about this item

Should I choose the 10W-30 viscosity grade for my high-mileage gasoline engine?

Yes, this synthetic blend is formulated for gasoline engines with 10W-30 viscosity, offering cold-flow performance down to -22 degrees F and a high-temperature viscosity of 11.9 cSt at 100 degrees C.

What does the 10W-30 rating mean for cold starts and running protection?

The 10W rating ensures flow at -22 degrees F for easier cold starts, while the 30 rating maintains a 11.9 cSt film at 100 degrees C to protect bearings and rings at operating temperature.

Does the SAE 10W-30 standard limit the pour point or flash point I will see?

The oil exceeds the baseline with a pour point of -22 degrees F and a flash point of 410 degrees F, providing a wider safety margin than the minimum SAE 10W-30 requirements.
