Ford's IOLM and Ecoboost engines

[Ken2]

Quote:
it was verified that the Ecoboost line of engines simply requires the use of Synthetic Blend or Full Synthetic which is similar to all Ford vehicles. ...The requirement for the oil is that, it must meet or exceed Ford Specification WSS-M2C946-A for the 2.0L Ecoboost engine.
Except this isn't right:

Is Toy the only manufacturer which gives one OCI for conventional and another OCI for synthetic? Thats interesting. I know Ford, GM, and BMW don't do that. In BMW's case, they force you to use syn, but don't give an option to use conventional at lower OCI.


VW's turbo'd DI engines are easy on oil. Even urban drivers are able to do 10k OCIs and turn in good looking UOAs. The only DIs that appear to be hard on oil are the ones running 87 octane.
