Well, I read on here a few days ago about GTX going to 16 bucks at Walmart a few days ago. It is 16 in North Texas as well. I like GTX but no way I am paying 4 bucks more when it is no better than any other oils out there for 12 bucks. Is this Walmart or BP pushing the price up? Actually, I was going to try PP. Is 5W20 not available in the 5 quart bottles? Matter of fact, they had no 5W20 at all in PP.
