<p>Pennzoil® High Mileage Full Synthetic motor oil is formulated to provide all the same benefits as our Pennzoil® Full Synthetic, with the added value of a high mileage formula. Specially created for vehicles with 75,000+ miles with seal conditioners to help rejuvenate old, dry seals and reduce oil consumption in high mileage vehicles.</p> <h3>How it Cleans</h3> <p>Pennzoil® High Mileage Full Synthetic motor oil is formulated with Active Cleansing Agents™. These powerful ingredients not only help prevent sludge and other deposits from forming, but also help remove existing sludge and varnish inside engines by gently lifting it from surfaces and safely dissolving it back into the oil. So every time you start your engine, the Active Cleansing Agents™ in Pennzoil® High Mileage Full Synthetic motor oil work to keep the car you love running for the long haul.</p> <h3>Clean is Crucial</h3> <p>All engines generate dirt, no matter how well they’re maintained. Today’s engines are more complex and often smaller with far tighter tolerances, yet they’re expected to provide better performance and higher fuel economy. So, motor oils that clean are no longer a luxury. Clean is now a necessity. Industry experts agree, a cleaner engine is better protected, more efficient and delivers optimum performance. And today’s motor oil consumers know that all good oils protect–they want one that goes beyond protection to deliver much more.</p>

It’s oil

Good value and works well

Received with several bottles busted...the geniuses at Sam's decided to pack the oil loosely inside a larger box, practically guaranteeing that it would get bashed around as much as possible. What were they thinking?
