Here's my procedure: get the vehicle up to normal operating temperature so the oil is warmed before you drain. I raise the front end up with a jack placed on the center of the front part of the engine cradle - there's a round nipple there that the round pocket of my jack fits right into. Once lifted, I place jack stands at each corner of the sub-frame/cradle and let the vehicle sit there. Using a 13 mm, 6-pt socket, I loosen the drain plug. Then I slowly undo the plug by fingers while holding a round plastic drain pan close to the drain so the oil doesn't splash all over my garage floor - once a steady flow state has developed, I lower the pan to the floor.
I let the oil drain until the rate is a few drops/minute. Then I replace the oil drain pan w/a smaller container and move the pan directly under the oil filter. I usually have no problem turning the filter with my bare hand (it shouldn't be on there that tight), but an oil filter wrench should suffice;^) I'd never use a Fram, however, and my preference is for the NAPA Gold (1085), but I have used the PureOne (PL14670 - it has been noted that the PureOne's may be a bit more restrictive, flow-wise, but they do filter well), and the AC-PF13. All the above filters are slightly larger than the stock OEM. The Saab filters are fine, but my local NAPA dealer is more convenient.
Anyway, once I loosen the old filter, I let it drain completely before totally removing it and try, though not always sucessfully because it's usually still warm, not to let it drop into the drain pan, splashing oil all over my floor.
One would think that because the oil drain plug is toward the back of the engine, lifting the vehicle from the front, so that it's at an angle would cause all the oil to drain completely out - but not in practice. I've found that if I remove the jack stands, and lower the vehicle back down on it's wheels, more oil will drain out. While this is happening, I oil the gasket on the new filter, and do Aeroguy's trick of annealing the copper washer on the drain plug - simply get it glowing red w/my handy blow-torch and drop it into a cold cup of water. After that, just about all the oil is drained and I lift the vehicle up, put the plug back, screw on the new filter, and add 5 qts. of M1 15W-50, the only oil I'd consider in my B234R engine......finis!
