I just had a UOA done using Castrol GTX 5W-30 in a GM 3100 and it was excellent.
GTX is a very good oil and will serve you well, but you might find better value for your money with another oil that is cheaper, like Pennzoil YB.
What kind of car are you running, driving conditions, and mileage?
Good oil, just too expensive for a dino. 
Good oil - thickest of the 5w-20s

I think GTX is one of the best conventional oils on the market.
Better than the highly touted Pennzoil YB ?

I use GTX as my "break-in" oil for new vehicles. After that it's too expensive for my liking.

My dad used to work for Chrysler for 20 years and have a service station before that and is a licensed mechanic (35+ Years). Trust me, those Shadows run on anything, just change it at a reasonable interval and don't overheat them and you will run forever!
My aunt had one with over 300K Miles before she was in an accident with it, and it was still going strong with only a bit of oil consumption!
I have posted before on how clean my father-in-law's 2002 Honda engine is. He has used GTX 5W20 and fram twice a year since new. Under the oil cap the valve train looks new. He has about 100,000 km on it.
A few months ago Walmart had 1 gal jugs of GTX on sale for $8.88.

No it's a 4 Cylinder Chrysler engine.

My nephew's Volvo chugs most oils like water. He ran GTX 10w-30 over winter and burned not a drop in 5k! I changed his oil w/o a top-off after adding like 3-4q over the previous ocis. Pretty convincing in that department.
Both my 02 grand caravan 3.3L and 09 fusion 2.3L love the stuff. The fusion has less valve train noise with GTX than most other oils I have tried syn and dino (tried many oils on my 06 also).
I have heard many complain on various other forums about the "ticking" from the 3.3L/3.8L in the caravans. Not the case with 5W-30 GTX (RX clean cycle).
I only buy GTX when it is really cheap at wal mart (sometimes at can tire) but may just buy more when it goes on sale. I can never seem to get PYB as cheap out here so I will stick with the GTX until then. If I keep getting these great results with this "cheap" oil I may just stick with it as my summer oil.
