Castrol GTX Engine Oil, 20W-50 – 5 Litres

Vehicles are staying on the road longer, and that means they need the right engine oil to keep them running strong. Castrol GTX is designed to fight engine sludge — a thick, tar-like substance that blocks oilways and affects performance.

With its 3X clean formula, Castrol GTX works to catch, control, and clean engine sludge — neutralising old deposits while creating a barrier that prevents new ones from forming. This superior cleaning helps extend the life of your engine, since sludge eventually affects every vehicle over time.

Key Benefits:

• Superior cleaning of engine sludge* caused by heat, contaminants, and short trips
• Advanced protection against viscosity and thermal breakdown
• Premium quality base oils and anti-wear additives to extend engine life
• Helps minimise oil consumption
• Keeps engines cool and clean
• Ideal for older, pre-2002 engines facing higher temperatures and stresses
