OIL GTX 20W-50

The Castrol GTX 3X-Clean formula has been developed to combat the three main causes of Sludge in the engine: temperature, contaminants and short distances.
Cleaning up existing sludge and creating a barrier that prevents the formation of new ones, Castrol GTX keeps engines clean for longer, 35% longer than industry standards*.
It is designed for all types of vehicles that require a lubricant with viscosity 15W-40 and ACEA A3/B4 specification and/or API SP or earlier.
