I just changed the oil on my 04 Honda Pilot. I was running Mobil 1 EP (Fram filter) and just changed it with 7,860 miles on it. I refilled it with Pennzoil full synthetic (gray bottle) using a supertech filter. I was curious what the forum thought was the better oil. Both oils were 5W20 as recommended by Honda. I am sending out a sample of the used Mobil 1 to Blackstone tomorrow. I would like to run the M1 or Penn Syn to 10K OCI. I recently switched to synthetic and wanted to complete an analysis before I drove to 10K on a single change. I might add, the majority of the miles on this car is around town. Unfortunately not much highway driving. It also gets really hot here in Socal in the summer. Your thoughts and opinions are appreciated.
