No Oil Keeps Engines Cleaner
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 oilways, 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.
