Quick question, my little brother just bought this car with low miles on it and i told him i would post this question. Is this car generally hard on oil? I know some are worse than others. We drained the 10w40 that the small dealership put in when they serviced it and went with the factory recommended 5w20. QS Horsepower 18 bucks at WM. I kinda think some places put the heavier oils in just to quite down the engines a little or reduce oil burning if there was an issue. That was just a side note.
