I know the 2.4 VVT-2009 model engine has a engine oil over heat warning that will cut power if the oil temp is too high. I never saw that before, also the oil change light comes on due to use cycle roughly every 2000 to 3000 miles. The more highway driving you do the less it comes on, The longest on my own cars I have gone is 6000 on synthetic oil and most was highway driving. I have seen 360s and 318 thatb went 20K on oil changes and they were not pretty inside but they ran. I have had 5.4 Fords go 25K and never been changes But I don't recommend it. They used semi suynthetic oil and have 7Qt capacity
