I found out last week that all of the Walmart stores in central Ohio were out of stock on Castrol Full Synthetic in all grades.
I called Walmart customer service and was told that all Walmart stores in all of Ohio were out of stock.
I called Castrol customer service and was told that Walmart is no longer selling the Castrol GTX Full Synthetic.
Walmart has also discontinued sales of the gold bottle Castrol Edge Extended brand.
Amazon is selling the GTX Full Synthetic product but just raised the price from $26.27 to $33.99. So much for an entry level price!
