Cars today face difficult conditions, and this is not going to change over time, it may even get worse.
Heavy loads, towing, long journeys on motorways and long periods of idling waiting for the family – all of these make for difficult driving conditions.
All this can cause high engine temperatures and high levels of pollutants from burnt and unburnt fuel that accumulate in the oil.
As a result, they can lead to the formation of thick sediment (sludge) in the engine, which can reduce engine life.
Castrol GTX ULTRACLEAN’s synthetic technology breaks down and removes existing viscous sediment (sludge) and protects the engine from future sludge formation, offering up to 50% more protection against sludge formation compared to strict industry limits*.
Castrol GTX ULTRACLEAN: No other engine oil keeps your engine cleaner.
