Shell Advance ensures maximum protection for your 4 stroke engine

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 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. 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.

Shear 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 reduce the amount of dirt that is generated from broken down viscosity modifiers, keeping 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.

Viscosity Loss

Shell Advance also contains special detergents that promote component cleanliness. Right up to the oil change, it keeps on removing and rendering harmless the stubborn black carbon particles that can build up rapidly on parts lubricated with less advanced formula oils.

Overall, Shell Advance performs better than other oils in the same class when it comes to evaporative stability, chlorine content and shear loss.

Shell Advance ensures maximum protection for your 2 stroke engine

Shell Advance base oil blend is specially selected to provide maximum protection to all key parts of a 2-stroke engine, especially the pistons, bearings and exhaust system. The choice of additives selected depends on the amount of stress and chemical attack that the bike components need to withstand.

As 2-stroke oil is fed into the bike via the fuel system, the oil and the important additives that protect it are continually consumed by combustion and replaced with a new fuel oil charge. As a result the oil is only exposed to the moving parts for a very short space of time before it is consumed by combustion. It is therefore very important that the oil is of a high quality to provide the protection the engine needs. Shell Advance base oil blend is specially selected to provide this protection to all parts of the engine and is exclusively formulated to keep bike engines and exhausts cleaner.

Using less sophisticated oils may result in higher friction and more wear to the bike leading to piston and cylinder scuffing, piston ring sticking and bearing seizure - problems that all affect your bike’s performance and ride. Shell Advance also minimises deposits during combustion, and so reduces the likelihood of blockages which can eventually lead to engine seizure.

Using Shell Advance also safeguards the engine from corrosion and helps to prevent other problems such as spark plug fouling, pre-ignition, exhaust system blockage and excessive smoke. All this adds up to a cleaner engine and exhaust system, helping your customers get the most out of their bikes for longer.

JPI tests show that Shell Advance VSX2 two-stroke oil keeps engines cleaner than other top oil brands.

 The higher the number the more deposits. In comparison with other leading brands, tests show that using Shell Advance VSX2 results in less carbon-based deposit formation on different types of pistons and cylinder heads. Higher levels of deposits can affect bike performance and damage components.

Key features of Shell Advance 2-stroke oils

• Low exhaust smoke production
• Superior control against exhaust system blocking
• High quality anti-wear protection
• Preservation of power
• High lubricity formulations to ensure that the moving parts are protected from metal-to-metal contact
• Meets or exceeds highest international specifications (JASO, ISO, API)

Modern bike engines require different oil formulations to cars.

As you know, years ago it was possible to put the same oil in bikes and cars. Since then car and bike engines have followed fundamentally different design objectives, meaning that nowadays, some 600cc Japanese road bikes produce twice the bhp per litre of a sports car by using engines with running speeds approaching 15,000 rpm. A sporty 105bhp 1.4-litre car with a 3.2-litre sump has an engine oil stress factor of approximately 23. A sporty 0.6-litre 123bhp bike with a 2.7-litre sump, on the other hand, has an engine oil stress factor of around 76- three times that of the car.

Under such engine speeds, lesser quality oils would evaporate from piston and other hot metal surfaces and fail to provide the protective films needed to safeguard metal components from damage. Which is why we developed Shell Advance. Bikes now accelerate much quicker than cars and this puts immense extra stress on their engines and oil.

Shell Advance is designed to help your engine withstand the stresses, so you get more from your bike, for longer.
