Built for Extended Performance
One of the biggest distinctions between regular Castrol EDGE and Castrol EDGE Extended Performance is right there in the name.
This oil is designed to maintain protection over an extended service period.
Castrol advertises protection for up to 25,000 miles or one year, whichever comes first, subject to its applicable conditions and recommendations.
That does not automatically mean every vehicle should travel 25,000 miles between oil changes.
Vehicle manufacturer requirements, engine design, driving conditions, oil-filter capability, warranty requirements and severe-service schedules can all dictate shorter intervals.
If your owner’s manual calls for 5,000 miles, “but the bottle said 25,000” probably won’t win the argument with your engine.
Exceptional High-Temperature Protection
Heat is one of motor oil’s greatest enemies.
High temperatures can accelerate oxidation and contribute to viscosity changes, deposits and deterioration of the lubricant.
This becomes particularly important in modern turbocharged engines, where oil can encounter extremely demanding thermal conditions.
Castrol EDGE Extended Performance is formulated for excellent thermal stability and advertises 50X better high-temperature performance based on Sequence IIIH testing versus API SQ test limits.
For performance cars, turbocharged daily drivers, hard-working SUVs and other demanding applications, that thermal resistance can be a compelling reason to choose a premium full synthetic.
0W-20 Protection from Cold Start to Operating Temperature
The SAE 0W-20 viscosity is designed to provide excellent low-temperature flow while maintaining the operating-temperature viscosity required by compatible engines.
During cold starts, rapid oil circulation is particularly important because the lubricant must reach critical components as quickly as possible.
Once the engine is hot, the oil must maintain an effective lubricating film despite increased temperature and load.
Castrol EDGE Extended Performance 0W-20 is engineered to handle both ends of that operating range.
Always confirm that SAE 0W-20 is the correct viscosity for your specific year, make, model and engine.
Advanced Wear Protection
Inside a running engine, crankshaft bearings, camshafts, timing components, cylinder walls and valvetrain components are subjected to continuous mechanical loads.
The oil film separating those components is one of the major things standing between normal operation and a repair bill capable of ruining your entire week.
Castrol positions EDGE Extended Performance as delivering its highest level of wear protection, helping protect critical engine surfaces under demanding operating conditions.
Its resistance to viscosity breakdown also helps maintain the lubricant characteristics necessary for reliable protection throughout its service life.
Helps Control Deposits and Sludge
Advanced motor oil isn’t only about reducing friction.
A quality lubricant also needs to control contaminants and resist the formation of deposits as the oil encounters heat, combustion byproducts and repeated operating cycles.
Castrol EDGE Extended Performance is formulated to help keep modern engines cleaner while maintaining lubrication under demanding conditions.
