Daughter’s 2007 Honda Civic with about 68,000 miles. She purchased it used at about 52,000 miles. It had regular but unknown oil/filter changes up to about the 52,000 mile mark. I have been giving it PYB 5W20 with a Purolator Classic at intervals based on the oil monitor. Should I do a cleaning cycle on the next oil change with something like PP? Or just stick with PYB? Something else? What do you think I should have as my regular oil and filter combo for this vehicle? Thanks for your advice.
