Castrol GTX Ultraclean 15W-40 Engine Oil is 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.

These cleaning elements help extend engine life and in turn providing extra protection on seals and gaskets that become worn over time. Suitable for passenger and light commercial vehicles, the use of premium quality base oils and anti-wear additives in Castrol GTX engine oil help protect and prolong engine life whilst keeping engines cool and clean.
