I took my car to Walmart for an oil change in May 2009, to save my husband the time and trouble of doing it for me. When my husband changed my oil again in October 2009, he removed the filter and found written on the filter the date of 12/17/08 and the initials of the service technician at another auto service center where we had work done (including an oil change) on December 17, 2008.
I was thoroughly disgusted to find out that the Walmart auto service center had charged me for an oil change in May, but had not actually done the work.
I have been driving around for 10 months with the same oil and filter, after paying Walmart to change the oil in May!
We took our receipts, the filter, and our complaint to the manager and he at least gave us a refund, and it doesn't appear that any damage was done to our vehicle because of their negligence. But never again will I trust Walmart with my vehicle in an attempt to save time!
