I used a Purolator Pure One filter. Only high end filter they had at Pep Boys. The problem I had today was with a Vavoline filter that was on the truck when I bought it. For some reason this filter (the Vavoline) is slightly smaller in diameter than the others and the wrench wouldn't grip tight enough.

As I stated above I had to wedge a big screwdriver between the body of the filter and the adjustable wrench.

Also:

This oil filter test page is easy to find so many of you have probably saw it already but I thought it was worth doing a link cause it was interesting:
