My wife took our Jeep Liberty to the dealer for some problems with turn signal. The service manager calls and says they'll have to replace. Fine. Says the oil should be changed. I say "NO!". I just changed it about 2 weeks ago (Pennzoil Platinum 5w30 for the winter). Other things they want to do: change air filter (I changed it some time this year, no), rotate tires (Okay), wiper blades (no, I can do it cheaper), adjust parking brake (yes, please). Wife comes home - they did everything I asked them not to, and didn't do what I did ask them to do! Needless to say I will be over there this week. I was thinking about leaving the oil they put in for about 1,000 miles. I just hope I don't get a big hassle over them paying for the new Penzzoil Platinum!
