GC is interesting because you can buy it for 5 bucks a quart at the local AZ, sometimes even cheaper, and it has the "stealth" factor in that 99.9% of the customers don't have a clue that it's something special.
Driving to Chicago to get some of that Shell Helix magic @ the Ferrari dealer for a king's ransom is probably exciting but not practical for most of us.
