I use the M1 filter as well, Pep Boys had a killer deal combining both 5qts of M1 and thr filter for $30.

Walmart has the 5qt jug for $27

The RP was in my 2004 350z with about 70K miles at the time. I have run RP for about 40K miles and had no issues prior. I pushed the interval to 6K and the master tech who inspected my Z said it looked horrible.
