• It exceeds the demanding requirements of International lubricant Standardization and Approval Committee GF-5.
• Cleans out up to 40% of engine sludge in the 1st oil change. Continues to clean in the 2nd oil change.
• Helps clean up engines by gently lifting sludge deposits off engine surfaces and dissolving them safely into the oil.
• Controls high-temperature oxidation and deposits.

Product Description ------------------- Pennzoil Motor Oil from the maker of the leading motor oil in America, an advanced proprietary conventional formula with Active Cleansing Agents. Not only helps prevent dirt and contaminants from turning into performance robbing deposits, but also cleans out sludge. Because at Pennzoil we know, a cleaner engine is better protected and responsive. It meets or exceeds the engine protection required by ILSAC GF-5 (SAE 5W-20, SAE 5W-30, SAE 10W-30), or API SN (SAE 10W-40, 20W-50), and is specially formulated to provide extra protection against the harmful effects of stop-and-go driving and high and low-temperature engine operation. .com ---- Motor oil is made from crude oil and is used to lubricate, clean, and cool engines. Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. Motor oil varies in weight and viscosity, as well as additives that some manufacturers add to the oil during the refining process. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity--the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance. SAE 5W-20 --------- This oil has a weight of SAE 5W-20, meaning it has an SAE viscosity rating of 5 in cold temperatures and a rating of 20 at normal operating temperature. Always check your vehicle's owner's manual to verify that this is the correct weight of motor oil for your vehicle. Conventional Motor Oil ---------------------- This oil is a conventional motor oil, meaning it is refined from crude oil or petroleum products. Conventional motor oils may or may not have additives included after refining. Conventional motor oils are more versatile than synthetic or hybrid motor oils, because they are suitable for use with nearly all types of modern vehicle engines, from cars and trucks to motorcycles, ATVs, farm equipment, and more.
