Pennzoil Platinum Synthetic oil advertises itself as lubricating the engine for 15 years or 500,000 miles whichever comes first? Is that claim true? Currently we do 3 month or 3,000 mile bulk synthetic oil changes at Walmart and the oil change sticker labels the bulk synthetic oil as Castrol Edge, also five quart Pennzoil Platinum Synthetic oil bottles advertise themselves as being made of natural gas, but how can a material in a gaseous condition be turned into a liquid that will lubricate the crankshaft, engine bearings, timing chain and timing chain tensioner, camshafts, camshaft bearings, camshaft lobes, valve tappets, and valve springs? I am asking because I know a little bit of physics or chemistry whatever science is responsible for identifying materials in different solid, liquid, and gaseous positions and so I don't know how can a gas be turned into a liquid that will lubricate the above engine parts for 15 years or 500,000 miles, Thanks, Alex Stathas

The claim made by Pennzoil Platinum Synthetic oil that it can lubricate an engine for 15 years or 500,000 miles is a bit misleading. While it is true that synthetic oils like Pennzoil Platinum can last longer than conventional oils, the actual lifespan of the oil depends on a variety of factors, including driving conditions, engine design, and maintenance habits.

In general, most automakers recommend oil changes every 5,000 to 7,500 miles for synthetic oils, which is much longer than the 3,000-mile interval for conventional oils. However, it's important to follow the manufacturer's recommendations for oil change intervals to ensure the longevity and proper functioning of the engine.

As for the claim that Pennzoil Platinum Synthetic oil is made from natural gas, this is also true. Synthetic oils are made from a variety of base oils, including polyalphaolefins (PAOs) and synthetic esters. These base oils are typically derived from natural gas or other petrochemicals and are then chemically modified to create the final product.

While it may seem counterintuitive that a gas can be turned into a liquid that can lubricate engine parts, it's important to remember that the chemical properties of a substance can change depending on its form. The base oils used in synthetic oils are specifically designed to have the necessary lubricating properties to protect engine components.

In summary, while the claims made by Pennzoil Platinum Synthetic oil may seem impressive, it's important to follow the manufacturer's recommended oil change intervals and to understand the science behind the production and properties of synthetic oils.
