0W, 5W, 10W will all work. Unless you live in Alaska, or so synthetic 10W is fine for a car that has lived on 20W. Put a jug of dino 20W-50 in the freezer. You don't want to know that it isn't pumping in your engine when not too much below freezing.
You very well may not get a leak...I just wanted to warn you not to blame the synthetic for causing the leak. If a car leaks right after changing to any other oil- I can gauranty that car already had a leak - you just didn't know it.
Amsoil 10W-30 is $5.70 a quart.
Top line Purolators are just OK. Fram is bottom of the line regardless the marketing name. Nothing wrong with Volvo OEM filters made by Mann. Amsoil, Mobil 1 and K&N oil filters are top of the line, but again you pay more.
A regular full flow filter will not filter 1 um particles. A bypass filter will.
It's a great sign that your flame trap is clean - how long have you had the car? Either the oil was changed very regularly or it was serviced not too long ago. In fact if it wasn't crusty there is some correlation that your seals may be in good shape AND have not be subject to undue crankcase pressure.
