I've been using the rubber strap wrench, medium size f/ Sears. Been working OK, tho I haven't liked the fiddling around w/ it to get it positioned and snugged just right to prevent slippage. I hand tighten the new filter w/ reasonable firmness - I'm not very strong, anyway. This spring when I changed filter while getting rid of winter storage oil, the damn rubber strap actually broke trying to loosen the filter. I'm going to try a different wrench, either the metal one pictured here (that Spke posted):Chromer said:I use the strap also. Fits well in tight places. $6 at the auto parts store.
