TRANSFORMS TO BE STRONGER UNDER PRESSURE This showed that Castrol EDGE with Fluid TITANIUM physically transforms its structure – becoming stiffer at points of extreme pressure, to keep metal apart and reducing friction. When the pressure subsides, the oil reverts to its free-flowing state.

Castrol EDGE transforms its structure under pressure to keep metal apart to reduce friction for maximum engine performance and delivers 6X better wear protection than required by the latest Sequence IVA test limits.

EXTEND MAXIMUM engine PERFORMANCE Castrol EDGE High Mileage provides 10X better high temperature performance* than the latest industry standard. As your car ages, it can lose performance and efficiency and is also more prone to catalytic converter failure.

Castrol Edge Extended Performance - Full Synthetic Oil It provides ultimate performance and the strength to enable an extended drain of 20,000 miles or a full year*.

between 25-65 PSI The unit of measurement is either PSI or Bar. The ideal oil pressure varies depending on the car brand and model, but generally, the ideal oil pressure is between 25-65 PSI.

Castrol is part of bp and is marketed in Malaysia under bp Castrol Lubricants (Malaysia) Sdn Bhd. The company has a proud heritage of innovation of over 90 years in Malaysia and is one of the market leaders in the retail automotive lubricants segment.

If you're looking for a reliable synthetic motor oil, then Castrol has you covered. This affordable synthetic engine oil option is designed to reduce engine wear leaving engine parts up to four times smoother through molecules that stick to the engine.

Castrol EDGE, an advanced full synthetic 5W-30 motor oil, is Castrol's strongest oil and a great option for those who want the very best for their car.

It has the strength to maintain this unsurpassed level of engine protection for an extended drain cycle of up to 16,000 km between oil changes which is the interval recommended by many vehicle manufacturers.

The expiry date is simply the point at which the motor oil starts to degrade and lose its effectiveness. How long does motor oil last then? On average, conventional motor oil lasts about five years on the shelf in unopened containers. Semi-synthetic and synthetic motor oils will last seven to eight years.

Oil pressure is created by a fluid flow restriction in the outlet line of the pump, not by the pump itself. Examples of such restrictions include big end and main bearings, as well as camshaft and rocker gear if fitted.

The oil pressure generated in most engines should be about 10 psi per every 1000 revolutions per minute (rpm), peaking around 55-65 psi. Local pressure (at the crankshaft journal and bearing) is far higher than the 50, 60 psi &c. set by the pump's relief valve, and will reach hundreds of psi.
