Castrol GTX 20W-50 - Motor Engine Oil (5 Litre)

Castrol GTX 20W-50 is a premium conventional engine oil engineered to provide superior protection against engine sludge and thermal breakdown. Daily driving conditions such as heavy traffic, harsh climate temperatures, and frequent short trips can cause sludge build-up that restricts oil circulation and causes premature engine wear. Castrol GTX features a double-action anti-sludge formula that cleans away old sludge while protecting against new sludge formation better than tough industry standards. Formulated with high-viscosity mineral base oils and advanced anti-wear additives, it provides exceptional film strength at elevated operating temperatures, making it ideal for high-mileage engines, older vehicle models, and hardworking engines operating under heavy loads.

Suitable for use in naturally aspirated, turbocharged, and multi-valve petrol and light diesel engines where the manufacturer recommends an API SL/CF or earlier specification 20W-50 lubricant. Always consult the vehicle owner’s manual to confirm the recommended oil viscosity grade and service classification.
