I got the 3 legged oil fllter wrench and it didn't fit into the recess on the pan. Tried to use some sand paper on the strap wrench and it wouldnt budge. Finally took the truck off the ramp and went down to the oil change joint that put the filter on the last time. They were pretty good and put the truck on the hoist to remove the filter. The guy said they only hand tight the filters. Yeah sure. They used a metal cap wrench to get it off, along with a big breaker bar. They put on a new filter, handtight, and added a quart of oil to make up for what was lost NC.
As a side note, the guys said the GM filters that are recessed into the oil pan are a bitch to get loose at times. Fair enough I guess. Glad I have a bunch of other cars I can use.
