oil and oil filter question..

[tekmoe]

im runnin amsoil 5w20. i put 3k on the original oil before swapping it out with the amsoil. did 6k on the amsoil and swapped it just a couple of weeks ago. ill probably go 12k on this oil and change the filter at 6k just to be safe.

I just found out a co-worker of mine's uncle sells amsoil, so I bought 4 quarts of oil from him (5w-20). The bottle said 7500 miles for oil change, is it safe to go further? And do I need amsoil filters or would I be fine with the mobile filters (heard they have a 98-99% efficency rating, better than the K&N I'm using right now.)
