Changing Engine Oil and Engine Oil FIlter
I have a 2004 Honda Accord LX at 111000 miles. The owner's manual says that I should replace engine oil every 5,000 miles (8,000 km) or every 6 months. However, most of the people around me says it should be done every 3,000 miles or every 3 months. Which one should be the guideline to be followed? It has been around 2.5 months since I changed the engine oil. I have noticed today that the oil is about in the middle between the full level and low level marks in the dipstick and its color has become darker. Moreover, do I need to replace the engine oil filter every time when I replace the engine oil?
