All cars, including those with the latest stop-start engine technology, do not perform at their best in traffic congestion. And as congestion has increased dramatically over the past 10 years, engine wear has risen while fuel is wasted.

Castrol MAGNATEC combines DUALOCK molecules with Castrol’s most efficient full synthetic base oils. These breakthrough DUALOCK molecules cling to critical engine parts and lock together to create a powerful force field of protection against engine wear.

They dramatically reduce both warm-up* and stop-start** wear by 50%, while providing non-stop protection and improved fuel economy*** from every start, even in vehicles with modern stop-start technology.

Castrol MAGNATEC 5W-30 A5 is suitable for use in petrol and diesel engines where the manufacturer recommends an ACEA A1/B1, A5/B5, API SN, ILSAC GF-5, or earlier specification 5W-30 lubricant.

• Tested vs. the API SN wear limit in the Sequence IVA test.
  ** Tested versus the ACEA wear limit in the OM646LA test.
  *** Compared to an industry reference 15W-40 oil.
