Castrol EDGE High Mileage with Fluid TITANIUM Technology is the natural choice for drivers who demand maximum performance from their high mileage cars, which often operate at extreme temperatures. Castrol EDGE High Mileage provides up to 10X better high temperature performance than the latest industry standard to ensure optimal protection and oil flow over the drive cycle. As your car ages, it can lose performance and efficiency and is also more prone to catalytic converter failure. Castrol EDGE High Mileage is liquid engineered with Phosphorous Replacement Technology to reduce harmful phosphorus to protect the catalytic converter and preserve the life of your emission system. Castrol EDGE High Mileage helps your car defy its miles and extend maximum performance.

Product Features:

• Patented phosphorus replacement technology to help extend the life of your emission system
• 10x better high temperature performance (as measured in sequence iiih engine test vs. api sp test limit)
• 6x better wear protection (as measured in latest sequence iva engine test)
• 1.4x better sludge protection (as measured in sequence vh engine test vs. api sp test limit)
• Maximum Performance: Castrol EDGE High Mileage with Fluid TITANIUM Technology is designed to provide maximum performance for high mileage cars, even in extreme temperatures.

Castrol GTX High Mileage motor oil is the leading consumer high-mileage brand. You won’t need to worry about using a high mileage oil or synthetic because this is both. It’s a synthetic blend engine oil that helps extend the life of your engine by protecting against sludge, wear and burn-off and also liquid engineered to protect your emission system. One of the leading causes of ‘check engine’ lights coming on in high mileage cars is actually catalytic converter failure, which can be caused by phosphorous in engine oil. While phosphorous is present in all engine oils for its ability to reduce wear, it is effectively poisonous to catalytic converters. Castrol GTX High Mileage Motor Oil is liquid engineered with Phosphorous Replacement Technology to replace some of the phosphorous with an advanced additive that maintains robust wear protection. When you want to extend the life of your high mileage engine and emission system and find out how many miles you can go on a high-mileage oil, there is no better choice than Castrol GTX High Mileage Motor Oil.

Product Features:

• Phosphorus replacement technology to help extend the life of the emission system
• Superior dispersancy that fights sludge build up
• Exceptional oil burn-off protection exceeding industry standards (based on api and acea volatility specifications)
• Improved fuel economy (in 5w-20, 5w-30 and 10w-30 grades versus industry specifications)
• Provides extra protection for older vehicles: Castrol GTX High Mileage Engine Oil is specifically designed to provide extra protection for high mileage engines, helping to extend the life of your vehicle.
• Synthetic blend composition: This engine oil is a synthetic blend, combining the benefits of both conventional and synthetic oils to provide superior protection against sludge, wear, and burn-off.
