Log book service intervals

[Homesport]

In recent years FoMoCo have recommended 12 monthly service intervals. A number of factors have been behind this trend, namely, improvements in engine lubricants together with more advanced electronic Management systems. This thinking may look good as a marketing tool, but in practice is it the best for the oily bits of the engine. Ford appears to have some agreement with Caltex ( Chevron USA ) worldwide to use Caltex lubricants.
Are Caltex oils are the right fit for the Ecoboost engine, i.e., LZ Focus petrol.
