CASTROL GTX ULTRACLEAN 10W-40 A3/B4 oil

Cars today face difficult conditions, and this is not going to change with the passage of time, on the contrary, it may get worse.

Heavy loads, towing, long highway journeys and long periods of idling while waiting for the family – all add up to tough driving conditions.

All of these can cause high engine temperatures and high levels of pollutants from burnt and unburnt fuel to build up in the oil.

Consequently, they can lead to the formation of thick sludge (sludge) in the engine, which can reduce the life of the engine.

Castrol GTX ULTRACLEAN's synthetic technology breaks down and removes existing thick sludge (sludge) and protects the engine from future sludge formation, offering up to 50% more sludge protection than strict industry limits*.
