What would you guys rather run in your usdm Fiesta ST 1.6l turbo? Castrol MAGNATEC or Castrol Edge 5w30? Currently running the magnatec, thinking of switching to Edge.
They are both fine engine oils.
The Magnatec is a lower cost option if that is a factor for you, and will be just fine for <5K OCIs.
The Edge is a more highly additized formula, and might use slightly better base stocks than the Magnatec.
It would probably stand up to DI fuel dilution a bit better, especially if you exceed that 5K miles on changes, but it is what, about $10.00 more per 5 quart/liter jug(??).
