What oil kind for a Chrysler sebring 2004?

Answer 1

The recommended oil is conventional 5W30 oil for this vehicle. You can use 10W30, but 5W30 is recommended and is considered an "energy conserving oil" which may give you slightly better fuel economy (1% to 2%).

You can also use full synthetic 5W30, but it is not necessary and is more expensive, but can go longer between changes, so it's a trade-off. Synthetic does reduce friction slightly, so may increase fuel economy over using conventional oil. Usually that is a 5% to 10% improvement.

However, if the car has any oil leaks, switching to synthetic will tend to make them worse. This is due to the difference in molecular structure between petroleum based oil and synthetic oil.

So you have a choice, but if you use 5W30 conventional oil and change it every 5000 miles, you will be following the manufacturer's recommendations and should have no problems.
