Amber synthetic blend oil in a one-quart bottle

Pennzoil

Pennzoil 550022818 High Mileage 5W-20 1 Qt

SKU CH-0MB4-V6NB9

High-mileage synthetic-blend 5W-20 engine oil in a one-quart bottle for gasoline engines

  • High-mileage formula protects older gasoline engines
  • Synthetic blend base resists breakdown at 446 °F flash point
  • Flows at -25 °F pour point for cold starts
  • 47 cSt viscosity at 40 °C maintains film strength
  • 1-quart bottle simplifies top-offs and changes

High-Mileage Engine Oil for Gasoline Vehicles

Pennzoil 550022818 is a synthetic-blend lubricant formulated for gasoline engines with higher mileage. The 1-quart bottle delivers a 5W-20 viscosity grade suitable for cold starts and normal operating temperatures. It targets reduced oil consumption and leak prevention in aging powerplants.

SAE 5W-20 Viscosity Grade Matches Manufacturer

The single specification that decides fitment is the SAE 5W-20 viscosity grade required by the vehicle maker. This oil meets that exact grade with a viscosity of 47 cSt at 40 degrees C and a pour point of -25 degrees F. Using a different grade risks inadequate film strength or cold-flow performance.

Stable Protection During Extended High-Temperature

Under sustained load the fluid maintains its protective film with a flash point of 446 degrees F and a specific gravity of 0.88 at 60 degrees F. The synthetic-blend base resists thermal breakdown better than conventional oil during long trips or heavy traffic. This consistency helps prevent sludge buildup and maintains oil pressure over the full drain interval.

Questions about this item

How does the 5W-20 viscosity behave once the engine reaches running temperature?

The 20 grade limits thinning at operating heat, keeping viscosity at 47 cSt measured at 40 °C and maintaining a specific gravity of 0.88 at 60 °F.

What performance ceiling does the SAE 5W-20 standard impose on this synthetic blend?

SAE 5W-20 sets cold cranking and high-temperature viscosity limits; this oil meets them with a -25 °F pour point and 446 °F flash point.

What does the 1 qt bottle require to fit and pour into a gasoline engine?

The 1 qt bottle fits standard quart openings and pours directly into any gasoline engine filler neck without special tools.
