Features

Castrol MAGNATEC Stop-Start 5W-20 E Engine Oil is formulated with Dualock technology, designed to provide exceptional wear protection for modern engines. This oil is specifically engineered for Stop-Start engines that frequently stop and restart during driving conditions.

The key feature of this oil is the Dualock technology. It contains intelligent molecules that cling and lock onto engine parts when the oil drains away during engine shutdowns. This provides an extra layer of protection during the critical moment of restart, allowing immediate lubrication for vital engine components.

This prevents metal-to-metal contact during restarts, reducing friction and engine wear. Tests indicate Dualock technology can reduce engine wear by up to 50% compared to other oils without this technology. So for Stop-Start engines that experience more frequent shutdowns, this oil helps extend engine life.

Overall the features focus on wear protection, friction reduction, and suitability for modern Stop-Start engines. The Dualock technology provides the core benefit of reducing engine wear during the high stress of engine restarts. This allows the oil to deliver exceptional performance in these types of engines.
