Castrol is home to some of the world's leading motor oils, including Castrol EDGE, Castrol MAGNATEC and Castrol GTX: liquid engineering for every car.
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 mineral engine oil, part synthetic or full synthetic. It's also true whether you drive a performance car or a high mileage classic.
Today’s engines are smaller and more efficient, without sacrificing performance. These advances in engine design challenge the oil with increased pressure. Castrol EDGE is our most advanced range of engine oils – designed to unlock the true performance of your engine when you need it most.
Castrol MAGNATEC's DUALOCK technology is the result of over 10 years of research and development by Castrol's technologists in partnership with one of the world's leading universities. DUALOCK technology uses the combination of different protective molecules, locked together at the surface to create a powerful force-field of protection.
The Castrol GTX range of engine oils help extend engine life by cleaning away harmful sludge, and protecting against new sludge formation. Castrol GTX is one of the world's most trusted engine oils, helping to extend the life of engines since it was first introduced in 1968.
