CASTROL MAGNATEC STOP-START 5W-30 Full Synthetic – 4 L is a premium full synthetic engine oil designed to protect modern car engines, especially under stop-start urban driving conditions. In typical daily driving—even normal drivers may stop and start thousands of times a year—engine wear mainly happens during warm-up and at each start. CASTROL MAGNATEC STOP-START uses Intelligent Molecules™ (DUALOCK technology) that cling to critical engine components to form a protective layer that helps reduce wear from the moment the engine starts and throughout stop-start operation.

This 5W-30 oil meets performance requirements for gasoline and some diesel engines where API SN and ACEA specifications such as A3/B3 and A3/B4 are recommended. It provides reliable protection, smooth performance, and continuous lubrication across a wide range of temperatures and driving conditions.

Key Features:

1. Full synthetic engine oil designed for daily stop-start city driving and highway use
2. Intelligent Molecules™ cling to engine parts, forming a protective layer to reduce wear at every start
3. Helps protect against engine wear associated with frequent stop and go driving
4. Maintains performance across varying temperatures and speeds
5. Meets industry standards API SN and ACEA A3/B3 & A3/B4

Application:

Ideal for passenger cars (petrol & diesel) where the manufacturer requires a 5W-30 full synthetic oil with API SN and ACEA A3/B3/A3/B4 performance. It is especially useful for drivers in busy city traffic or frequent stop-start conditions.

How to Use:

Completely drain the old engine oil. Pour in the required quantity of CASTROL MAGNATEC STOP-START 5W-30 Full Synthetic 4 L, and then check the oil level with the dipstick. Follow the vehicle manufacturer’s recommended oil change intervals.
