Newbie here... I have a 2012 and 2013 Honda Civic Sedan LX. The '12 has 14k on it and the '13 has 8k on it. Both cars use the same oil filter and both require an API certified premium detergent 0-20w conventional oil according to the manual. I've been changing the oil on both vehicles around 4k...mostly because that's just the way I've done it. However, seeing that it's really no longer necessary to do so and the manual recommends a 7.5k or 12 month oil change interval. I've been using Mobil 1 0-20w of the advanced fuel economy version and a Purolator Pure One (Yellow) filter. Looking to go to the manual recommended interval of a 7.5k oil change. These cars are not driven hard, and a split between city/highway driving. What do you think about my current oil/filter pairing going 7.5k? I don't know if I'm more worried about the filter than the oil lasting that long or just whether they both will go that long. Would stepping up to the Purolator Synthetic filter or something like the Wix XP be a better match for this? Would there be a better oil to go along with either of these filters to go the 7.5k? Open to your suggestions. Thanks for your time!
