2008 Accord, 4 cyl, grandmothers car. has about 70k miles. she puts about 15k miles a year. she used to get her oil changed by the guy with the local tire shop, sadly he passed away a few months back. I'll be doing her maintenance now. what sounds like a better combo, PYB 5W20 and a P1 filter for 3500-4k miles, or Mobil 1 5W20 and a Purolator synthetic filter for 5k miles? was also thinking of a Napa gold but ive heard the filter media is small in those filters,should there be any concern using a NG?
