Millions of drivers across the world are unaware that their car engines are being needlessly
The problem with 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.
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.
The problem with engine oil is that it drains off your engine when you need it most - which is why Castrol's scientists have worked so hard to prevent this.
The breakthrough achieved is Castrol Magnatec's intelligent molecules - molecules which give oil the power to cling to critical parts even when your engine is turned off; ready to protect from the moment you start. They bond to metal surfaces in your engine, forming an extra layer of protection, dramatically reducing* engine wear.
Because they cling to critical engine parts, the protection is already there when you need it most - while the engine warms up.
* As tested against the industry Sequence IVA wear test.
Castrol Magnatec's ultra-refined molecules are in unique formulations, exclusive to Castrol Magnatec.
Even though gravity forces the oil to drain down into the sump, the intelligent molecules cling so tenaciously to the engine's surfaces that they continue to cling to your engine after it has warmed up. The oil helps maintain top engine performance by protecting your engine in all driving conditions and at all temperatures. And when your journey is over, the intelligent molecules keep clinging to critical engine parts so they're able to protect when you start your next journey.
Castrol Magnatec's ability to cling to metal surfaces is a real leap forward in oil technology.
Castrol Magnatec's innovative solution to engine wear happens at a molecular level - but this doesn't mean the benefits are invisible to the naked eye. In fact, we can demonstrate how it protects your engine from unnecessary wear in very tangible ways.
Castrol Magnatec intelligent molecules are now ultra-refined, for protection you can see, hear and feel.
Tests show that engine parts protected with Castrol Magnatec intelligent molecules are 15 times smoother** than those without. In fact, the level of abrasion on the first component is such that if you were to run a fingernail over it you could feel and hear the scratching sounds caused by the tiny grooves in the metal. Clearly this kind of damage to key components is not ideal if you want your engine to perform with maximum efficiency.
The image below shows two engine test parts from two identical engines. You can see quite clearly that the one not lubricated with Castrol Magnatec has clear evidence scratches and abrasive wear. By contrast, the part that was protected by Castrol Magnatec intelligent molecules is much smoother with very few signs of damage.

The evidence you've seen has been put through its paces in 18 test cells at Castrol's UK Technology Centre in Pangbourne. The oil is tested in engines that run for up to 1,000 hours at a time, placed under different stresses to help us understand how it responds to the full range of modern driving conditions. This level of rigour allows us to have complete confidence in the benefits of Castrol Magnatec.
Under a scanning electron microscope the contrast is even more dramatic. These engine parts are subjected to huge pressures and the only thing that protects them is the thin coating of oil. Clearly, the clinging power of Castrol Magnatec's intelligent molecules ensure this protective layer stays intact at all times preventing the kind of damage you see on the metal surface on the left.
If you haven't been using Castrol Magnatec in your car, the good news is that you can still take advantage of its proven protective power. We've tested the intelligent molecules on engines with significant evidence of damage from abrasion. The evidence shows quite clearly that if you switch to Castrol Magnatec you slow that wear rate dramatically.
Castrol Magnatec's Intelligent Molecules start working for you the moment you change your oil. Castrol Magnatec's intelligent molecules cling and bond to engine surfaces, dramatically reducing further wear to already worn parts.
So if you haven't been using Castrol Magnatec in your car, the good news is that you can still take advantage of its proven protective power.
Switching to Castrol Magnatec is easy. With our oil selector you can find the right oil in a matter of seconds and we can also show you where to buy Castrol Magnatec. Then you can simply let your garage know that you would prefer them to use Castrol Magnatec at your next service.
