The risk of engine wear
Castrol MAGNATEC helps defend engines from wear in four critical areas which can impact efficiency and performance:
Inside an internal combustion engine (ICE), the valvetrain controls the combustion cycle. The opening and closing of the intake and exhaust valves is controlled by the precise profile of camshaft lobes as they move against the pushrod lifters.
Valvetrain lubrication is vital to reduce friction and wear at these high load contact points, as wear on cam lobes can lead to loss of power and increased fuel consumption.
Castrol MAGNATEC allows synchronisation of the valvetrain and helps maintain engine efficiency.
In many of today's fuel-efficient engines, a metal timing chain performs a vital role - synchronising the rotation of cam shafts and crank shafts with engine intake and exhaust valve cycles.
Proper chain lubrication is vital to ensure the engine runs at optimum performance and efficiency. Using the right oil for each vehicle's chain helps minimise damage and elongation.
Castrol MAGNATEC helps prevent against chain elongation and wear, which helps maintains chain tension and precise engine timing.
When an engine is running at 1000 RPM, each piston could be going up-and-down 2000 times per minute.
Piston and cylinder liners are designed with grooves (or cross-hatches) to optimise oil distribution, ensuring separation of precision metal-to-metal contact points.
Over time, unburned fuel and aged oil can build-up, forming abrasive deposits on the pistons which can cause damage to cylinder liners. This wear may lead to a lack of compression, which can affect performance and fuel consumption.
Castrol MAGNATEC helps maintain piston cleanliness and defends cylinders against abrasion, so all components can perform at optimum efficiency.
In a modern engine, bearings such as the cam-shaft, crank-shaft and pin bearings all support other engine parts, keeping vital components in precise alignment, creating stability and allowing smooth rotation.
Although small, without proper lubrication, engine bearings are susceptible to scoring, wear and failure, so other larger parts can not perform as they should.
Castrol MAGNATEC helps provide a long-lasting film of oil between the shells and moving parts, keeping everything running smoothly and preventing against corrosive wear.
Frequently asked questions
Engine wear occurs as a result of metal-to-metal contact between precise components. If these components come into contact, it can result in abrasion, wear and damage. This can reduce the efficiency of the engine or even result in failure.
The only thing standing between engine components is a thin layer of oil.
Engine oil is designed to maintain your vehicle's engine health and improve its performance. There are a variety of different types of oil available such as mineral, part-synthetic and fully synthetic. The higher the synthetic content of the oil, the greater the level of protection and performance and fuel efficiency you can expect.
Oils also come in a variety of viscosity grades. This is a measure of the thickness of the oil and its resistance to flow. The numbers often referred to with oils indicate the oils ability to flow at cold and hot engine temperatures.
We'd always recommend that you refer to your vehicles manual for the ideal viscosity and oil specification. You can also use the Castrol oil finder with your vehicle's details to see which viscosity is right for your engine.
