Because they flow better at low temperatures, it’s possible to manufacture thinner synthetic oils and it’s these low viscosity oils that modern engines need to help reduce fuel consumption and emissions.

Synthetic oils also have a higher film strength, which gives better protection and reduced wear. And, as they are more stable and less volatile at high temperatures, they work better for longer, effectively reducing the engine’s oil consumption.

Mineral oils are derived directly from the crude oil refining process, whereas synthetic oils are altered by chemical processing which improves their chemical structure.

As a result, synthetic oils perform better than mineral oils at all temperatures and are more durable.

As they are higher quality, offer higher performance and longer life, fully synthetic oils cost more than mineral oils.

No. Look instead for a reputable brand like Mobil Delvac, for a product that meets specifications set by industry and original equipment manufacturers and buy products you know to be authentic from a trusted supplier.
