I see.... but when i ask to jaguar mechanic in Italy, he recommend Magnatec

 

Castrol EDGE is a full synthetic engine oil; Castrol MAGNATEC is a semi-synthetic. (Castrol MAGNATEC Professional is a full synthetic but not widely available). Castrol EDGE is their premium product line.

According to CASTROL the differences are:
Castrol EDGE does not have the same technology as MAGNATEC, the two have different additive systems. Castrol MAGNATEC has intelligent molecules that cling to critical engine parts like a magnet, providing an extra layer of protection from the start and throughout warm-up that won’t drain to the sump. Castrol EDGE has a more advanced technology with fluid titanium that provides superior engine wear protection. It provides a higher level of high temperature protection, anti-wear performance, and viscosity stability.

The important thing is to ensure the oil you choose meets or exceeds Jaguar specification for viscosity and API. Both products are premium oils suitable for your vehicle. It is therefore little more than a choice by personal preference and availability.
