I had to have the 1.6L Ecoboost engine in my 2015 Ford Escape replaced. As some of you may know, a lot of these engines had to be replaced due to cracked engine blocks. Mine was covered under the powertrain warranty. I'm sure that the new engine was filled with Ford's synthetic blend of oil. I had been running Mobil 1 in the original engine--and the engine failure was certainly not due to a problem with the oil! But my research has indicated that Royal Purple may be a better motor oil than Mobil 1. However, my engine now has fewer than 300 miles on it, and Royal Purple advises to wait until your engine has at least 2,000 miles on it before using their oil. This is, supposedly, so that valves and piston rings can wear and seat properly. Now, when getting a new car, I normally change the oil between 500 and 1,000 miles, to get any metal particles out that could have resulted from the break-in process. So, what would happen if I put in Royal Purple at around 1,000 miles? Would that prevent the engine parts from "wearing in" optimally? Thanks in advance for your answers.
