Whatever car you drive, and whatever the manufacturer's specification, there is a Castrol® motor oil that has been created by our Liquid Engineers to provide the best possible protection. That's a fact whether you want conventional motor oil, semi synthetic or full synthetic. It's also true whether you drive a late model, high performance car from a European manufacturer or a high mileage American classic.
Modern day engines are smaller but more powerful than ever, operating at more than twice the internal pressure of older engines. Castrol® EDGE® is our strongest motor oil, fully synthetic and liquid engineered with Fluid Titanium Technology to make it strong enough to handle the demands of today's engines at all times.
Tough driving conditions like idling on congested highways and frequent, short trips put peak loads on critical engine parts and create engine wear. Environmental factors like heat can lead to sludge, varnish and carbon build-up in your engine. That's why Castrol GTX Full Synthetic is engineered to provide maximum protection to help extend the life of your engine. It provides an extra layer of protection that clings to engine components to dramatically reduce engine wear. It also helps to clean away old sludge and protect against new sludge formation.
Sludge can form in engine oilways, blocking them up to reduce power and engine life. Castrol® GTX® is a premium conventional motor oil that has been helping to extend engine life since 1968. It does so thanks to a double-action formula that cleans away old sludge and prevents new sludge from forming.
