The book also says to torque the filter to 13 ft/lbs.... which is insane...
When I was Tech Editor, I tested that torque once, and ren 4k miles, I wrecked 5 different filter wrenches trying to remove the filter, and ended up shooting a screw thru a cup wrench into the filter, so I could get enough torque to remove it....
At that torque, the rubber is totally flat, and the metal can rim is tightened against the boss...
hand tighten, then another 1/2 to 3/4 turn with a wrench is all it needs... trust me on this.....
