Castrol motor oil and lubricants
Why choose Castrol motor oil?
With more than 100 years of expertise and an international reputation for innovation and high-performance engine oils, Castrol has developed a complete range of advanced motor oils for your car. At NAPA Auto Parts, you’ll find synthetic, synthetic blend, high mileage, conventional, and diesel oils. Castrol has the right oil for every kind of engine, no matter the driving conditions.
Castrol Edge full Synthetic motor oil
The Castrol Edge range is highly recommended for protecting your engine from severe weather and driving conditions. Using Syntec technology, the oil neutralizes acids, protecting your engine against corrosion and rust. The protective film that it forms on the engine walls is twice as powerful as the previous formula, reducing friction and oil breakdown. Enriched with liquid titanium, Castrol Edge has a viscosity that’s three times as stable as most oils on the market.
For optimum performance, use Castrol Edge Extended Performance, Castrol’s premium grade, the most powerful liquid titanium enriched oil. Its unparalleled power lets you extend oil change intervals up to 24,000 km and maintain a tough and efficient line despite difficult driving conditions and temperatures.
For European diesel vehicles, choose Castrol EDGE 5W30, developed in collaboration with the Volkswagen Group.
For new 4-cylinder engines, Castrol EDGE 5W30 A3 / B4 is specially formulated to withstand very high temperatures.
Castrol MAGNATEC full synthetic motor oil
Castrol MAGNATEC full synthetic motor oil guarantees peak protection against engine wear. Its active formula allows the oil to form a protective film that attaches to the metal walls of your engine. Even under extreme temperatures, this oil keeps its optimum viscosity and protects the engine during cold starts.
Castrol GTX conventional oils
Difficult driving conditions such as heavy traffic, poor fuel quality, harsh weather conditions, and extended oil change intervals can all cause a build-up of a thick, tarry substance known as "sludge". If left untreated, this sludge can rob the engine of power and shorten its life.
Castrol GTX oils are specially designed to combat the harmful build-up of sludge, reduce oil deposits, and provide daily protection for your engine.
For vehicles with over 120,000 km, Castrol designed GTX High Mileage motor oil. All motor oils with additives contain phosphorus to prevent engine wear. Yet it’s known in the industry for “poisoning” catalysts. GTX High Mileage is specially formulated with less phosphorus than other conventional high mileage oils on the market, helping prevent catalytic converter and emissions system failures. Also reduces leakage and improves fuel consumption.
Castrol GTX Diesel motor oil is a premium product formulated to give diesel-powered cars and trucks superior lubrication. It fights piston deposits, oil thickening, and general engine wear. It also contains antioxidant additives to fight against corrosion.
