Definite 5 star
I have used Valvoline for years and have NEVER been disappointed. All of the employees do a wonderful job. They are quick and curteous. The one time there was a problem, they took care of it and all of my service was free, over $200. Although I said I would pay, they insisted it was on them. And the problem had nothing to do with their service, just a new bug in Ford F350s. They truly are great and are proud to show their belief in God too. Top notch.
