My Jeep is spec-ed for a mid-size filter (same as the SRT-4, I think), as is the same Jeep with the 4.0 I6. With the 4.0, the larger filter (FL1A size, 5.0 Mustang filter) fits just fine, and bumps the oil capacity from about 6 qts to about 6.25 qts. Mine, however, will require relocation to use it, as it would hit one of the upper control arms for my front axle.
Call me crazy, but I actually try for mpg with this Jeep:

Typical driving: Back in Rochester for school, driving is 60 - 70% city
