CASTROL GTX ULTRACLEAN 5W-20, 1 Qt

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- 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. When tested in engines with high level of sludge.
