CASTROL MAGNATEC

"Up to 75% of engine wear happens during warm-up - and that can take as long as 20 minutes"

The Problem The unseen damage that's eating away at your engine

Millions of drivers across the world are unaware that their car engines are being needlessly worn away.

So what is this unseen damage? And why does it happen?

The problem with some conventional motor oils is that as soon as your engine is switched off, the oil begins to drain from the engine parts, dripping to the bottom of the sump. Only when your engine is started again does it begin to circulate – but this takes time so there's a crucial period when key components are most vulnerable to the intense forces at work within the engine.

'As soon as your engine is switched off it begins to drain from your engine parts'

Castrol's scientists have discovered that up to 75% of engine wear occurs during warm-up.

The result? The engine's critical parts suffer needless damage. The effect of wear on some parts is so dramatic you can actually see, hear and feel it.

So what can be done?

Castrol Magnatec is the result of almost 20 years of continuous development by the scientists and engineers at Castrol's many technology centres around the globe. Their latest development is the 'ultra-refining' of the key component that provides the clinging protection in Castrol Magnatec's unique formulations. See Castrol Magnatec's solution to engine wear.
