Castrol GTX High Mileage 5w30 Motor Oil (2 pack, 5-quart bottles)

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.
