Today even a normal driver can stop and start as many as 18,000 times a year. All that idling in traffic causes microscopic wear in your engine. In the latest industry test, Castrol Magnatec Stop-Start 5W-30 gives significantly less wear in stop-start operation.

Castrol Magnatec Stop-Start 5W-30 contains intelligent molecules that:
- Cling to engine parts when the oil drains down
- Form a self-healing layer to protect at each of the critical stages of stop-start driving and beyond
- Are proven to reduce wear in stop-start operation

Castrol Magnatec Stop-Start 5W-30 is suitable for use in automotive petrol and diesel engines where the manufacturer recommends an API SN, ACEA A3/B3, A3/B4 or earlier specification 5W-30 lubricant.
