I do all of my own oil changes and are very faithful to never go over 5000 miles (despite what the display may say for oil quaility). My TH, V-6, has 19,000 miles on the clock and has always run perfectly. My question is every time I have changed the oil the dip stick shows it to be over filled by like 1/4" above the full mark after a few hundred miles. The last change I let the vehicle drain for over one hour! I put exactly 6 quarts and of course a new filter. Within one hour it showed exactly full, a few hundred miles later it is showing above full. Have never needed to add any antifreeze, oil does not smell like gas. This is driving me crazy since I do not want it over full and I end up taking like 1/3 of quart out to bring it down to full. Is it because of the oil in the cooler that does not drain out? Any ideas?
