i figured that this story was a horror story. my truck came out with out a air filter once, and i always check it a little ways down the road to see if they changed my oil, (cause thats happened to me too.) i had to take it back and tell them to give me a air filter and i almost got into a fist fight cause the manager tried to say that i just took it out and tried getting a freebie. so i change my oil my self now.
