Kia K900: Recommended SAE viscosity numberAlways be sure to clean the area around any filler plug, drain plug, or dipstick before checking or draining any lubricant. This is especially important in dusty or sandy areas and when the vehicle is used on unpaved roads. Cleaning the plug and dipstick areas will prevent dirt and grit from entering the engine and other mechanisms that could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather operating (engine start and engine oil flowability).
Lower viscosity engine oils can provide better fuel economy and cold weather performance, however, higher viscosity engine oils are required for satisfactory lubrication in hot weather. Using oils of any viscosity other than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be operated in before the next oil change.
Proceed to select the recommended oil viscosity from the chart.

1. For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 5W-30 (API Service SM / ILSAC GF-4).
However, if the engine oil is not available in your country, select the proper engine oil using the engine oil viscosity chart.

1. For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 5W-20 (API Service SM / ILSAC GF-4).
However, if the engine oil is not available in your country, select the proper engine oil using the engine oil viscosity chart.

To equalize tread wear, it is recommended that the tires be rotated every 7,500
miles (12,000 km) or sooner if irregular wear develops. During rotation, check the
tires for correct balance.
