What do Grades mean

WHAT DO THE GRADES MEAN?

Motor oils use a rating system developed by SAE, which is the Society of Automotive Engineers, to classify oil by viscosity. We’re all used to seeing designations like SAE 5W-30 or SAE 10W-30, so let’s talk about what they really mean.

For multi-grade viscosity motor oils, the cold-temperature viscosity is labelled with a “W,” which stands for “winter.” Thus, in an SAE 10W-30 motor oil, the “10” is the cold-temperature viscosity rating and the “30” is the high-temperature viscosity rating. This combination provides a motor oil that flows well at low temperatures, but still protects the engine at high temperatures.

For comparison’s sake, SAE 5W-30 and SAE 0W-30 will flow better at even lower temperatures than 10W-30 while still providing protection at high temperatures. Just remember, the “W” stands for winter.

Please refer to your owner’s manual or our Motor Oil Selector tool to ensure you are using the recommended motor oil for your vehicle.

Pennzoil® Gold

Synthetic Blend Motor Oil

Pennzoil® Gold helps clean out sludge lesser oils leave behind plus keeps pistons up to 10% cleaner than the toughest industry standard.1

Cleansing and Protection 3 star rating

Pennzoil® Gold is a synthetic blend motor oil with a combination of high-quality conventional and synthetic base oils and additives to provide better protection for severe driving conditions (such as stop-and-go driving, frequent short trips, extreme temperatures, idling and towing) than conventional oil. Pennzoil® Gold keeps pistons up to 10% cleaner than the toughest industry standard1 and helps clean out sludge lesser oils leave behind.2

1Based on ILSAC GF-5 and Sequence IIIG piston deposit test using SAE 5W-30.
2Based on severe sludge clean-up test using SAE 5W-30.
