I have been using Mckinney Oil X-Change for a few years for oil changes, this morning they tried to rip me off by telling me that I needed new spark plugs. In January I had my mechanic change my belts and spark plugs on my vehicle. The so called mechanic came in and told me my spark plugs needed to be replaced oh really I said they were replaced in January. The spark plug he was showing me doesn't match what my mechanic used. I will not deny that removed the spark plug but the one he was showing me was dirty and burnt. When I got home I removed the spark plugs and they were clean and it was a dealer part not an after market product. I am so disappointed in Mckinney Oil X-Change that I feel I need to tell everyone my story.
