You're thinking of the (ACDELCO) PF25(short) PF35(Long) and PF1218( same as PF35 but with an internal check valve) for Chevy Small and Big block V8's

Its on the right track,and those oversize filters are listed in the Purolator and AC Delco books, but they have kinda over looked Mercedes.

I use mobil one and change between 1.5k and 3k miles (still clear amber color) but I can't ever leave well enough alone

Anyone else have any ideas?
