O'Reilly's just recently had a sale on Havoline oil.I was going to buy 5qts of 5W20 (still have 1 qt of MS5K) for my next oil change. Counter guy said Havoline doesn't make 5W20. WM does not sell 5W20 either. I checked Havolines website and they show it. Is there a reason it is not sold in certain areas?
I'm thinking about sending Havoline an e-mail asking why.
