Oils Frequently asked questions about Castrol EDGE

Castrol’s Strongest and Most Advanced Range of Engine Oils

It strengthens the engine oil's, enhancing it’s ability to minimise metal to metal contact between your engine parts, lowering friction and maximising engine performance for longer even when under pressure

Excellent levels of protection across a variety of driving conditions and temperatures
Maximised short and long term engine performance
Improved engine efficiency (independently qualified)
Sustained performance even when under pressure

Increased confidence to go and drive how you want, when you want, knowing that your engine oil has the strength to not let you and your engine down
Ability to achieve maximum engine output for longer
Savings from improved engine efficiency

We believe Strength to be the single most important attribute in an engine oil for the technology in today’s car parc
The oil's ability to minimise metal to metal contact occurring in your engine especially when under intense pressures, providing continuous engine protection and maximising engine performance output is a direct result of your engine oils strength

The Fluid Strength Test tells us how strong the oil is at minimising metal to metal contact; the more contact that occurs, the more likely friction is to increase, the more likely performance is to be impacted, the more likely that engine wear will occur and long term engine performance is impacted

The MET proves the enduring strength of the oil. It indicates the oil's ability to resist breaking down, continual ability to cope with engine pressures and deliver extended engine performance and remain stronger for longer no matter what the variety of conditions or the way you drive
A complete test and comparison of the oils ability to continually excel at doing its job even when under pressure; cleaning, lubricating, cooling, protecting, allowing maximum performance to be achieved.
