One of my daughters just got a 2011 Ford Fiesta SES which has the 1.6 L Duratec Ti-VCT Engine. It is in very good physical and mechanical condition. It has about 135K miles on it. The previous owner has maintenance records showing religious oil changes every 4K miles.
According to the owner's manual, "use Motorcraft SAE 5W-20 or an equivalent SAE 5W-20 oil meeting Ford specification WSS-M2C930-A."
For those with knowledge and experience with this particular engine, what do you think about running a 5W-30 (full synthetic) instead? I'm thinking Liqui Moly SPECIAL TEC AA SAE 5W-30.
That would allow me to stock a single oil for use in both of my daughters' vehicles, the other one being a 2012 Dodge Journey Crew AWD with the 3.6 L Pentastar engine.
