I don’t want to get into a remarkably long debate but curious what you guys will be running. For the last decade I’ve run a Mobil1 Full Sythetic in my vehicles. At the 6,000mi interval I change the oil, I haven’t found sludge or anything to suggest the oil had broken down enough to harm my engines. I used to run the Motorcraft parasynthetic oil but it required a shorter change interval (I found it to be 4,000mi or less). And with these Ecoboost engines there has been great debate regarding the best oil; regarding fuel blowing past the piston rings into the crankcase, diluting non-synthetic oil, and the fuel/oil/air mix finding its way back up the crankcase breather tube, into the air intake, and baking onto the intake valves closest to where this recycled air enters the air intake.
Eventually there will be many options for air/oil separators (aka “oil catch cans”) for the Ranger, but in the meantime I’d like to run a synthetic that will reduce the deposits being left on my valves.
