Castrol EDGE 5w-40 A3/B4 Boosted with TITANIUM FST
With worldwide emissions regulations tightening there is a renewed challenge to produce more power whilst still improving engine efficiency. Never before has engine oil played such a key role in delivering performance.
Engines are complex, with many moving parts – movement that can waste useful fuel energy through inefficiency. With these losses, power can be impacted. The challenge is to maintain the high performance levels expected by drivers, whilst engine technology adapts to meet the demanding legislative limits.
Castrol EDGE is stronger under pressure. It unlocks your engine’s performance and efficiency to deliver more power with the same fuel.*
Castrol EDGE: unlock the very edge of performance. *
Greater power delivery for the same amount of fuel used compared to the 5W-40 baseline, demonstrated by engine testing for more than 80% of the Castrol EDGE portfolio in global sales volume in 2021.
Castrol EDGE 5W-40 A3/B4 is suitable for petrol and diesel carsand designed to meet the latest specifications required by modern engines where the vehicle manufacturer recommendsand ACEA A3/B4, API SP or earlier specification 5W-40 lubricant.
