Engine Oil The numbers on the container's label tell you the oil's viscosity or weight. Select the oil for your car according to this chart. Synthetic Oil You may use a synthetic motor oil if it meets the same requirements given for conventional motor oil: energy conserving, a service classification of SJ, and the proper weight as shown on the chart. When using synthetic oil, you must follow the oil and filter change intervals given in the maintenance schedule. Additives Your Honda does not need any oil additives. Purchasing additives for the engine or transmission will not increase your car's performance or longevity. It only increases the cost of operating your car. Ambient Temperature An oil with a viscosity of 10W-30 is preferred for optimum fuel economy and year-round protection in your Honda. You may use a 5W-40 oil if the temperature in your area goes below 0°F ( 20°C). 164 Maintenance
