On my ford taurus sho 2011 It was driving fine the other day when all of a sudden where the mileage and MPG are displayed an oil lamp appeared. I looked at the oil level and it seems as if it was a quart low so i added a quart and the problem ceased. I did an oil change about 3K miles ago w/ the recommended full synthetic oil. today i took a drive and everything was fine no lights or anything until i got back after an hour drive and let my car sit for about 20 minutes. I went back outside to run to the store and then all of a sudden the same oil lamp indicator appeared and i checked my oil dipstick and it was low again already. I had no huge amount of smoke coming out my exhaust but I also do not have any visible oil leak so i thought most likely somehow i was burning oil. just an FYI, my turbo has already been replaced and I have had no other issues like this until this super cold weather begun. does anyone know what this could be or why my oil level keeps dropping? Please help me out!!!
