Synthetic motor oil, by contrast, is engineered in a laboratory using uniform base stock molecules or chemically modified compounds. Some drivers notice slightly better fuel economy after switching to a low viscosity synthetic, especially during highway driving.
Synthetic Motor Oil Better Long Term: Durability and Engine Protection
Compatibility with Modern Engine Technology Newer vehicles often incorporate variable valve timing, turbochargers, high compression ratios, and exhaust gas recirculation systems that place additional stress on the lubricant. Longer intervals can mean fewer service visits and reduced waste oil over the life of the vehicle.
How Synthetic Motor Oil Is Made Conventional oil is refined from crude petroleum, where molecules of different sizes and shapes are separated. Drivers routinely face a choice at the service desk or while ordering oil online: stick with conventional mineral oil or upgrade to a synthetic blend or full synthetic.
Synthetic Motor Oil Better Long Term: Engine Protection and Drain Intervals
Long Drain Intervals and Engine Protection Synthetic formulations resist oxidation and sludge formation longer than conventional oils, which allows for extended drain intervals when the manufacturer and oil meet the required specifications. If your vehicle manufacturer specifies synthetic, or if you frequently face extreme temperatures, short trips, towing, or spirited driving, the upgrade is often worthwhile.
