The Gunter Specialty Guarantee

“My truck had very low oil pressure until it warmed up.  Took it to the Chevy dealer, they hooked it up to the computer to look for a reason, but were unable to identify the problem.  I was reffered to Gunter in Valley Mills by a friend so I wanted to give them a try.  They were upfront and honest with me, kept me informedof their progress, and were able to fix the issue.  Thanks, Gunter Specialty, for the help!!”
