well i usually run mobil1 5w30 and mobil1 filter and change every 5k, i was hoping to run amsoil 530 (or 0w30?) syn and change it every 10k (if safe, i run my car hard) and a GOOD filter. i have never heard or read anything bad about mobil1 oil filters, or k&N.
but what do you think about amsoil oil filters?
amsoil 5w30 and ea oil filter should be great for more than 10k miles, right? i'd never go past 10k on oil/filter regardless how long they last, but i'd be safe running my engine hard with amsoil oil/filter for 10k right?
