The modern world creates difficult challenges for engines.
 
Poor fuel quality, heat and tough driving conditions can all lead to sludge formation that potentially shortens engine life. Sludge is a sticky deposit that builds up in an engine�s vital oil-ways and it can prevent oil from protecting the engine.
 
Castrol GTX ULTRACLEAN synthetic engine oil technology has superior performance. Its unique Double Action formula cleans away old sludge, and protects against new sludge formation, giving you more control over today�s challenging conditions.
