Hi all...I'm finishing up my Auto RX "rinse" and want to convert the PT Cruiser to a synthetic when done. After reading this forum I wondered where I might find some of this great green elixir. I'd stopped by the AZ's in the local suburbs and only GC Gold or the yellow US label stuff was to be found. For the heck of it I mapped out a bunch of AZ's where I figured people might not be willing to pay $5.00 for a quart of oil and management might not have cleared old stock for new. After only 4 stops (these AZ's are only a few miles apart) I found 12 quarts of 04 vintage (which I bought) and at least 35-40 quarts of 02 (2002) GC! I didn't buy the 2002 stuff due to my concerns about it's age and not sure what the formulation was then. Is this stuff still good? Was the 02 stuff the "right" stuff? (excuse my ignorance but I'm just getting acquainted with the green GC...just as it fades from availability alas...). I'm going to hit a few more locations in search of more and would like some advice as to the 2002 labeled stuff...appreciate any input or advice.
