WARNING: This page is about a different car, the 2013 Jeep Patriot and 2013 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
There are a number of engine oils being promoted as either synthetic or semi-synthetic. If you choose to use such a product, use only those oils that are certified by the American Petroleum Institute (API) to display the "Certification Mark" and show SAE viscosity grade recommended for each vehicle. Follow the service schedule that describes your driving type.
