What are fully synthetic motor oils?

Shell Helix fully synthetic oils are manufactured from 100% synthetic base stock and high quality additives to achieve higher performance levels than both synthetic technology and mineral oils. To these high-quality synthetic base oils we add our proprietary Active Cleansing Technology to create a motor oil that helps provide superior cleansing and protection for today’s engines.

Fully synthetic motor oils help protect your engine.

It is not just freezing Arctic conditions or blistering deserts that push oil to extremes. Everyday motorway driving or congested city traffic, where the car repeatedly has to stop and start, can mean severe conditions for engine oil. Shell Helix Ultra’s fully synthetic formulation offers Shell’s maximum protection in very hot and extremely cold climates, and severe driving conditions.
