As vehicles age, they change and some of these changes can result in costly repairs or replacement. Catalytic converter failure is the most common and costliest problems faced by higher mileage vehicles (vehicles with over 75,000 miles). The phosphorous in motor oil anti-wear packages is also an industry-recognized catalytic poison. Castrol GTX high mileage is specially formulated with less phosphorous than other leading motor oils, replacing it with advanced technology invented and patented by Castrol, that helps prevent catalytic converter and emission system failure. Castrol GTX high mileage also protects your vehicle against oil-related engine damage.

Castrol GTX high mileage motor oil is for engines with over 75,000 miles. Castrol GTX high mileage protects against deposit build-ups in your engine. Castrol GTX high mileage delivers unsurpassed protection against sludge, wear and oil burn-off vs. leading motor oils. Castrol GTX high mileage has seal conditioners to help reduce leaks and advanced additives to minimize engine wear. Castrol GTX high mileage has improved fuel economy and superior disbursement that fights sludge build-up and exceptional oil burn-off protection exceeding industry standards, based on API and ACEA volatility specifications.

Castrol high mileage oils can offer advanced performance over both synthetic and conventional nonhigh mileage products focusing specifically on conditions that an aging engine can experience. a high mileage oil contains base oils and additives designed to take care of aging engines while also being completely suitable for newer engines. while high mileage oils do have additional performance features, as with any motor oil, one should always follow the manufacturer’s recommendation for proper oil grade, performance specification and oil drain interval. oil drain intervals can be found in the owner’s manuals or by using the oil life monitor found on the dash of many of today’s vehicles.
