I got the same car. No need to let it warm up. They say you can drive off right away. There is no break in period like there is with European makes.FYI The older engines American made cars were larger V8's and straight 6's and the oil pumps less efficient, so it took longer for the oil to get around to all the parts and build up oil pressure to cushion the metal parts(that is the reason for the warm up without a load).
