Took 2 cars to Walmart (old one in town) and selected Value Package Oil Service.
Car 1 - found fluids not topped as in plan, no vacuum cleaning of interiors, no windshield clean and no window shield washer fluid added. Also found some charges for battery terminals that were unchanged... So took back and technician checked and added transmission fluid and had battery charges reversed.
Car 2 - Oil was black!!! as if not changed at all, no vacuum of interior, no windscreen clean, no topping of fluids, so took it back and manager said it did not look okay (oil being black) and that he would have the oil change done again for free. Also promised to top off all the fluids as required. Later found that the fluids were again not topped. But oil change was done second time for free.
I will never go to Walmart for oil change again. Do not know how many times they did this earlier... with inexperienced or non professional technicians. The technicians seem like temps. Last time I went for oil change, they replaced my battery with a new incorrect battery and did not even fix it. Upon noticing that the clock had reset in the car, I checked hood and found the problem. Spoke to manager... who had my old good battery put back and gave the replaced battery to me for free as 1). It was tech fault to replace battery and put incorrect battery and also not connect the clamps back again on the car 2.) They could not sell the battery again.
