What's the right pill to use 5w-30 full synthetic or synthetic blend ??
Thanks
Cost extra tAll Expeditions come from the factory with the Motorcraft Blend. If you are changing regularly(less than 7K) full syn is overkill. The Motorcraft Blend is rated pretty well by 3rd party testers. I get my oil changes from my Dealer for free. Cost extra to do full synthetic. If you are going longer intervals or towing everyday, sure Synthetic makes sense. Otherwise stick to t Blend.
The diff between Full synthetic and regular oil is that Full synthetic protects your engine better and can also last longer. I would still change out full synthetic oils at no more than 4k miles for ultra engine protection and makes the engine last even longer. I dont use full syn just so that I can wait longer for oil changes. I would never go over 4000 miles without an oil change in these ecoboost engines no matter what oil is in it.All oil brands have flashy marketing, but all are similar in the end. The Oil Specification (the odd letters and numbers) is what you are looking for, not the brand. Also, regular oil performs the same as synthetic as synthetic is modeled after regular oil. The benefit of synthetic is it lasts much longer. Ford recommends semi-synth probably because its lasts throughout the recommended oil change period and is slightly cheaper.
