Pennzoil PENZ1040 10W-40 Synthetic Blend Oil 1 Qt

SKU CH-ZFS2-EZFSH

Synthetic-blend 10W-40 engine oil in a one-quart bottle for gasoline engines

  • Synthetic blend protects gasoline engines
  • 10W-40 viscosity suits wide temperature ranges
  • Flash point 399°F resists high-heat breakdown
  • Pour point -22°F ensures cold-start flow
  • 1-quart bottle fits standard top-off needs

Pennzoil 10W-40 Synthetic Blend Oil

Pennzoil 10W-40 synthetic blend engine oil comes in a one-quart bottle for gasoline engines. The amber fluid carries a 10W-40 SAE viscosity grade and a flash point of 399 degrees Fahrenheit. It suits drivers who need conventional protection for daily commuting or older vehicles. Buyers requiring a full synthetic formulation or a different viscosity grade should look elsewhere.

Sustained viscosity and temperature stability

The oil maintains a viscosity of 15.4 cSt at 100 degrees Celsius and 20.5 cSt at 40 degrees Celsius. A pour point of minus 22 degrees Fahrenheit allows cold-weather flow, while the high flash point resists thermal breakdown during extended operation. Specific gravity measures 0.87 at 60 degrees Fahrenheit. Engines that demand a certified full synthetic or a manufacturer-specified approval code are not covered by this product.

Compatibility checks before ordering

Confirm that your engine specifies a 10W-40 viscosity grade and accepts a synthetic blend base formulation. Verify the required fill volume, as this container provides only one quart. Ensure the service interval matches conventional oil change schedules rather than extended-drain synthetic intervals. Vehicles requiring a distinct OEM specification or a different SAE grade will not be served by this oil.

Questions about this item

How hot does this 10W-40 synthetic blend oil get before it flashes?

The flash point is 399 degrees F, so it resists ignition well above normal engine operating temperatures.

What engine type must my vehicle have for this Pennzoil PENZ1040 oil to be compatible?

It is formulated for gasoline engines only; do not use it in diesel or alternative-fuel powerplants.

Will the 15.4 cSt viscosity at 100 degrees C protect my older high-mileage engine?

That viscosity falls within the SAE 40 range, providing the film strength older clearances typically need.
