Castrol has been a forerunner in lubrication technology and their latest product for the Indian passenger car market is the Magnatec with Dualock technology. This oil claims to offer added engine protection, specially for cars being used within city limits, in bumper to bumper traffic. In such a situation, the engine gets abused a lot due to constant acceleration and braking, as well as idling for longer periods. Both of these combined, add greater stress on the engine, which results in higher wear and tear of engine parts. The Castrol Magnatec with Dualock aims at reducing this wear and tear by adding an extra field of protection.

The company has been conducting research for the last ten years, with help from Department of Chemistry, University of Cambridge, to develop this product. It has been tested for over three million kilometers, before introducing it in the marketplace. It also has patented this technology in several countries and is under process in India too. This oil is specifically designed to provide non-stop engine protection, not only during warm up but also during stop-start driving conditions.

As emission norms are getting more stringent across the world, manufacturers are taking all efforts to make cars greener and more efficient. Now, to make engines cleaner and greener, manufacturers need to depend on good lubricants, which can help reduce friction and damage to engine parts, thus keeping them running with minimal usage of fuel. This in turn helps reduce emissions. Castrol has taken the game further with the introduction of the Dualock technology, which provides greater resistance against engine wear, thereby increasing the efficiency. Less wear and tear results in good fuel efficiency as well.

According to Simon Edwards, Head of Technology, Castrol India and Middle East: “Castrol Magnatec with new and unique Dualock technology uses a combination of two different protective molecules that lock together at the engine surface to create a powerful force-field of protection, delivering a ground breaking 50% reduction in warm-up and stop-start wear. Castrol Magnatec Stop-Start 0W-20 and Castrol Magnatec Stop-Start 5W-30 offer an additional benefit of fuel efficiency of up to 60 litres per annum.”

Castrol Dualock


In India, cities have started becoming crowded and the car population is leaping forward in numbers. This has lead to more traffic congestion. Not only does this add pressure on our infrastructure, but commuters spend more hours behind the wheel. The congestion leads to continuous start and stop of cars, resulting in higher wear. Car engines also run on idling for long periods and this puts further pressure on parts and the they wear faster. Castile Magnatec Dualock aims at reducing this wear significantly with the new technology.


Kedar Apte, VP Marketing, Castrol, India said, “Both car engines and drivers are under considerable stress in today’s congested traffic conditions. The average driver can stop and start as many as 18,000 times a year and can spend up to 1/3 of the journey time idling. This puts up to 66% more load on critical engine parts compared to driving on the open road. The reinvented Castrol Magnatec formulation with ground breaking Dualock technology is engineered specifically for such stressful driving conditions. We believe that this launch will further strengthen Castrol’s leadership position in the passenger car segment in India.”

The Dualock technology is available on the full range of the Magnatec product portfolio with different viscosities. It addresses the evolving needs of the Indian passenger car market. Castrol Magnatec 10W-40 is suitable for petrol and Castrol Magnatec Diesel 15W-40 for diesel engines. Castrol Magnatec Stop-Start 5W-30 is suitable for application across Petrol, Diesel and CNG engines. Castrol Magnatec Stop-Start 0W-20 for petrol engines is also introduced with this new launch. The good part is that this variant costs only around 25-30% more than the regular one. Castrol Magnatec as a brand has close to 10% market share overall and is a market leader in the premium segment of car engine oils in India.
