I run 20w-50 gtx with Lucas in my 22r, I am in a warm climate however. I don't burn much oil. I do have a little blue smoke at start up but not at any other times, and I figure that is valves. I use the thicker oil because once my truck gets hot and you kill it leaks oil like crazy right on top the front drive shaft u joint.

Using thicker oil is kind of like putting a band-aid on a cut that needs stitches. It will help, but you're just putting off the inevitable. Half a quart per fill-up is a lot. I would do a leak down test on it to see if it's the rings. If the rings are ok just do the top end, if they're bad do both. If you can't do a rebuild right now thicker oil should keep you from having to top off every fill-up, but I would plan on a rebuild in the near future.

are you sure there isn't a puddle of oil on the ground? that's a lot of oil consumption!
heavier weight oil should only be used in hotter climates or when you have problems keeping oil pressure. i use 5-50 full synthetic in my chevy truck because at 313,000 miles the clearances are a little bit wider and it helps keep up my oil pressure.
fix what is consuming your oil! you shouldn't need more than a quart between oil changes on any vehicle.
and do you know for a fact you aren't burning oil out your exhaust? have a friend follow you up a hill, i bet he sees some blue smoke you can't pick up in your mirror while you drive.
