I have been working out of town for the last few weeks so I stopped at Expert Tire for a Kendall synthetic blend oil change. I had a coupon right off the Expert Tire websight for Kendall oil. After about 30 min. I walked back to see them putting in the last qrt of Advance Auto conventional oil. When I asked about it they said they just ran out. Funny my truck was there for 45 min. and they had this oil on hand but they just ran out. Everything in the store on all the paperwork said they used Kendall motor oil.
