Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can’t compete with the overall engine performance and protection provided by synthetics.

Overall, full synthetic oils provide better engine performance and protection than conventional and synthetic blend motor oils. Mobil 1™ advanced full synthetic motor oils are specially formulated with a tailored additive system that provides additional performance benefits above and beyond those found with conventional and synthetic blend oils by:

Synthetic oils are created through complex processes, including being chemically developed from petrochemicals, to have the exact molecular qualities needed for a specific application.

These processes remove impurities from the crude oil and enable individual molecules to be tailored to the demands of modern engines. These customized molecules in synthetic oils provide higher levels of performance and protection than conventional oils.

Engine parts are in constant contact with each other and moving at high speeds. In the extreme environment of your engine, components can wear and break down. Your motor oil is the only protective barrier between these components.

As conventional and synthetic blend oils break down, typically, their ability to prevent engine wear diminishes. But Mobil 1 full synthetic oils retain their wear protection properties for a much longer time, helping to increase engine life by keeping important engine parts in excellent condition for 250,000 miles.*

As oil circulates through your engine, it can pick up deposits. Over time, conventional oils can form sludge, which can reduce your engine’s efficiency and, ultimately, reduce the life of your engine. Mobil 1 full synthetic oils contain fewer impurities compared to conventional and synthetic blend oils and can better resist the formation of sludge and deposits in your engine. If your engine already has sludge, Mobil 1 motor oils clean up virtually all engine sludge in just one oil change.
