Welp, time to file a small claims suit against Walmart. Got an oil change the other day and noticed something was off after a few miles of driving. Come to find out, these numbskulls overfilled my oil by almost an entire quart, which is ridiculous enough on its own. Come to find out they also didn't put a washer on my drain plug which can lead to oil leaks (which it is leaking), stripping of the threads in my oil pan, and the plug being fused to the pan through galvanic corrosion. When I returned to get a refund & file a complaint the MOD tried to say they did nothing wrong and refused to pull up the service history for my vehicle. Oh, you don't want to give me the service history? Well I guess I'll just have it subpoenaed then fuckstick. Have fun paying for my new oil pan and my legal fees.
