Oil Usage
According to the manual on the 2003 from the the full mark to the add mark is 2 quarts. I would alot rather run a engine a little low (above the add mark that is) on oil than it to be over full. Couple of years ago had one of those quick lube places do one of my gassers, and noticed the oil pressure gauge had a different reading from normal driving back home. Checked it after about 30 minutes, an it was three inches over the full mark. Called the manager of the quick lube, and told him it was over full, and he sent a man out to my house, and changed it again with five new quarts of oil.
