I recently moved to upstate NY from FlawDUH where I purchased this car & as soon as I got here I bought Mobil 1 oil & had the mechanic change the oil, etc. In the last month everytime I drive the oil gauge registers only at 80, the far end of the gauge and never sits in the middle where it sat when I was in FLA...do you think this is from cooler weather and the oil being thick? I just want to be sure nothing serious as winter is fast approaching. Thanks so much. JOY
