Castrol GTX 10W-40 A3/B4 engine oil is suitable for use in petrol and diesel engines in which the manufacturer recommends the use of lubricants of specifications ACEA A3/B3, A3/B4 or API SL/CF viscosity grade SAE 10W-40.
Advantages of Castrol GTX 10W-40 A3/B4:
A special sludge-resistant additive composition provides protection against these contaminants up to 25% better than industry standard standards;
excellent thermal stability and viscosity stability;
effective anti-wear additives contribute to extended engine life.

Severe vehicle operating conditions, such as frequent stop-start operation, harsh climates and extended oil change intervals, can lead to the formation of thick, resinous deposits called sludge. Sludge build-up in your engine can lead to poor oil circulation and premature engine failure.
Castrol GTX effectively protects your engine from these deposits.
