Castrol Magnatec is not magnetic, but since even educated people seem to struggle with electrostatic attraction and molecular polarity, this would be a difficult marketing story, hence the magnet
analogy.
As per Castrol in some parts of the world.

Castrol Magnatec 5W-40 SP is a synthetic SAE 5W-40 multigrade
engine oil that utilizes Unique Molecular Attraction to form a
lubricating surface on engine parts, protecting vital components at
start-up and during warm-up better than ordinary oils. Castrol
Magnatec 5W-40 integrates Unique Molecular Attraction with
Castrol’s proven advanced lubrication technology to deliver
exceptional performance in all conditions, whether stop-start or city or highway driving.
Castrol Magnatec 5W-40 SP contains a synthetic ester unique to
Castrol. The molecules of the ester are strongly attracted to metal
surfaces, forming a film on these surfaces that provides enhanced
wear protection in the engine. The protective film of lubricant provided by this Unique Molecular Attraction remains adhered to internal metal surfaces when the engine is idle or switched off for weeks or months.
