Hello everyone,
Like all of you I am now obsessed in finding where to buy GC. I went to 3 different AZ's today and found 12 quarts of GC. I found myself looking at the green oil with amazement when I changed the oil tonight.
My question is this. I could only find 2 bottles that are pre '05 production date. Do you think there is anything to be concerned about with the '05 formula?
I have a '05 Yukon w/ the 5.3 with 4k miles. Previous to just changing over to GC I have changed the oil 2 other times. How long would you recommend I run this oil for? The majority of the miles are highway miles.
I can't wait to do a analysis on this oil and of coarse the minute I do I will post it here.
Thank you for your help
