This is undoubtedly a strange question, but here goes. My Ford C-Max Energi is coming up on eleven months and 10K miles with Mobil1 0w-20 EP. That includes 3200 miles of highway driving and another 600 miles of short trips in winter where heat was needed. The latter trips were either 18 miles or < 7 miles with the latter being qualified as severe duty. The owner's manual calls for a 20K or two year OCI, but the oil really has only 4K ICE miles on it.
Valvoline Restore and Protect is intriguing, but there is only one UOA posted to date. The marketing claims are that it cleans pistons but I have no reason to believe or not believe that my engine is in need of cleaning.
Moving on to the HPL PPMCO, the cost is obviously much higher. What is intriguing about this oil is its cold temperature properties. The ICE on a PHEV can start without warning in very cold weather. It is unlikely that my vehicle will ever need to start below zero degrees F, but occasionally I do take a winter road trip that can push that down towards minus 20.
So to wrap up the questions, I am thinking about changing the oil before winter and letting the ICE run for < 7 miles at times when I need heat. Any and all opinions will be considered. Thanks in advance.
