As vehicles age, they change and some of these changes can result in costly repairs or replacement. Catalytic converter failure is one of the most common – and costliest -- problems faced by higher mileage vehicles. The phosphorus in all motor oil anti-wear packages is also an industry recognized catalyst poison.
Castrol® GTX® High Mileage is specially formulated with less phosphorus than other leading oils, replacing it with advanced technology invented and patented by Castrol that helps prevent catalytic converter and emission system failure and delivers unsurpassed protection against sludge, wear and oil burn-off*

Castrol GTX is one of the world's most trusted engine oils. The modern world creates difficult challenges for engines. Poor fuel quality, heat and tough driving conditions can all lead to sludge that potentially shortens engine life. Sludge is a sticky deposit that builds up in an engine's oil-ways and it can prevent the oil from protecting the engine. Castrol® GTX® Ultraclean's synthetic blend technology - with its proprietary sludge buster - is our cleanest GTX ever. Its unique Double Action formula cleans away old sludge** and protects against new sludge formation, giving you more control over today's challenging conditions. Help extend the life of your engine with GTX Ultraclean.
