hi to everyone, i'm new to the forums, i have an 05' c230 and i recently hit the 76000 miles mark, no problems so far, just a broken door handle wich i hear happens a lot, anyway, my question is, do you guys recommend other oil besides the Mobil1 0w20, i been using it since i got the car, but recently i took a trip from New Jersey to Florida around 3000 miles back and forth and the car consumed around 1qt of oil. Is this normal at 76000mi? will a thicker oil help? and also, do you change oil by the recommended intervals? thanks for all your help.
