My buddy and i are having a debate on his situation. Hes got an 06 s2000 that he only drives mainly in spring and summer. He changed the oil this past may and roughly put only 1200-1500 miles on the car this past season. He only changes the oil once a year to be noted. I told him that because he only put so little miles on the car this past season that when he changes the oil in the spring that he should not change the filter and just just use that filter again and not have to change it. Filter being used is a oem honda 15400-pcx-004. Lets get some opinons on this. Should the filter be changed? or should he use it for the 2015 spring/summer season?
