Castrol EDGE – A Modern Synthetic Engine Oil

In the last 30 years, engine pressure has almost doubled in conventional vehicles, making it crucial for an engine oil to be as strong as possible. No oil provides that strength quite like Castrol EDGE does. Castrol EDGE is boosted with TITANIUM FST to double its film strength and performance under extreme temperatures and pressures.

So, what’s the secret of TITANIUM FST? How does it provide the boost in strength that Castrol EDGE is known for? The additive’s state-of-the-art Fluid Strength Technology works hand-in-hand with soluble titanium polymers, changing the way that the oil behaves when it is working under pressure. This equates to maximum strength, maximum protection from engine deposits and – most importantly – maximum engine performance.
