I have gone to Ken at Tune Tech for several years now. I live on the west side of the Denver Metro area, so it's quite a drive for me to get to Ken's shop, but I've found that it's worth it. On this trip, I made a "wait on it" appointment to have several automotive fluids inspected, and changed if needed. Ken and his technician pulled a sample of the fluids that I suspected needed to be changed, showed me the condition of the fluid, and worked with me to decide if it was time to change the fluid based on condition. Almost ALL of the shops that I've been to previously would never take the time to do that. That's one of the many reasons that I do business with Ken and his guys. Additionally, Tune Tech uses BG fluid additives to help my mid-2000's Chevy Tahoe last as long as possible. That is sincerely appreciated give the condition of the new and used car market. Ken, I'll see you again when I need your help.
