Whatever car you drive, and whatever the manufacturer's specification, there is a Castrol® engine 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 engine 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.
Up to 75% of engine wear takes place in the first 20 minutes after your engine starts. That's why Castrol Magnatec is liquid engineered with intelligent molecules that cling to engine components and form a protective layer from the moment you start the engine, to dramatically reduce engine wear.
Sludge can form in engine oilways, blocking them up to reduce power and engine life. Castrol® GTX® is a premium conventional engine 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.
