I have been a customer for many years with W.H. Thomas oil. Bill and Howard are very knowledgeable on the Chevron products, as well as the rest of the staff. Jason is quite helpful also. He has got us out of some mechanical problems more than once. To summarize, these are great people to deal with. The best thing is how dependable they are, they are there when they say they are going to be. Keep it up folks!
