MAINTAINING YOUR VEHICLE 199 SAE 5W-30 oil is preferred for use in 2.7L engines within the operating temperatures shown in the viscosity chart. You are highly encouraged to use SAE 5W-30 oils to aid in low temperature starting and for improved fuel economy. Synthetic Engine Oils There are a growing 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 meet the American Petroleum Institute (APIJ) and SAE viscosity standard. Follow the service schedule that describes your driving type. Materials Added To Engine Oils The manufacturer strongly recommends against the addition of any additives (other than leak detection dyes) to engine oil. Engine oil is an engineered product and it's performance may be impaired by supplemental additives. Disposing of Used Engine Oil Care should be taken in disposing of used engine oil from your vehicle. Used oil, indiscriminately discarded, can present a problem to the environment. Contact your 3.5L Engine Oil Chart The proper SAE viscosity grade of engine oil should be selected based on the following recommendations and be within the operating temperature shown in the engine oil viscosity charts. SAE 10W-30 engine oil is preferred for use in 3.5L engines within the operating temperatures shown in the viscosity chart. SAE 5W-30 engine oil is allowed for use in the 3.5L engines during cold weather only to improve cold weather starting. 7
