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®

Conventional Motor Oil

Pennzoil® motor helps clean out sludge lesser oils leave behind.1 One more reason more people trust Pennzoil® than any other oil.2

Cleansing and Protection 2 star rating

Pennzoil® motor oil is a traditional oil base, fortified with Active Cleansing Agents to continuously prevent dirt and contaminants from turning into performance-robbing deposits, helping to keep your engine clean and responsive. In fact, Pennzoil® motor oil helps clean out sludge lesser oils leave behind and keeps cleaning all the way to your next oil change.1
