Getting more from your bike
By keeping your engine clean Shell Advance ensures maximum protection for your bike.
Shell Advance oils are made up of a special mix of top-quality synthetic, semi-synthetic, or mineral base oils.
Special high-performance additives are also mixed in to help provide long lasting protection against engine stress and improved cleanliness.
It takes years of oil formulation experience to come up with the right formula for Shell Advance and the way various additives are mixed in with the base oil is crucial to its overall performance.
Shear Loss
With less sophisticated oils, intense shear forces can lead to breakdown of viscosity modifiers that are added to prevent oils becoming too thin as the running temperature increases.
When this breakdown occurs, small carbon particles are released into the oil and can form sludge deposits around the engine.
These can lead to carbon and lacquer deposits especially at hot engine parts such as pistons and piston ring grooves, resulting in starting problems, power loss and failure to protect pistons from metal loss.

Viscosity Loss
Shell Advance is specially formulated to take advantage of a narrower viscosity range to reduce the amount of viscosity modifiers that are needed to build wider span multi viscosity motorcycle oils.
This reduction in viscosity modifiers has shown in laboratory testing to help reduce the amount of dirt that is generated from broken down viscosity modifiers, helping to keep the engine cleaner for longer.
This graphic reveals that Shell Advance is very shear stable and retains 98.5% of its viscosity after the Bosch Injector test, staying in grade longer.
Shell Advance also contains special detergents that promote component cleanliness. Right up to the next scheduled oil change, it keeps on removing the stubborn black carbon particles that can build up rapidly on parts lubricated with less advanced formula oils.
Evaporative stability, chlorine content and shear loss
