If you are wanting to use Castrol Magnatec you will need the at least 10w 40 or 15w 40 to maintain protection under load.
Otherwise their Edge 5w 30 is a very good oil
As for the word magnatec that Castrol use its really just advertising material.
Castrol found that when they "Hydrocrack" an oil it made the molecules of the oil charge positive - it's not really magnetic!
Also just a little information on synthetics
While I would have no hesitation using Castrols Edge it's not really a true Syntheic oil - it's been "Hydrocracked" to profrom in a simula way to a Syntheic oil.
Mobil 1 is a true Syntheic PAO oil and starts its life as a top grade oil. All marketing stuff aside it's one of the best.
