*1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other
additional benefits, they contribute to fuel economy by reducing the amount of fuel
necessary to overcome engine friction. Often, these improvements are difficult to
measure in everyday driving, but in a year’s time, they can offer significant cost and
energy savings.
*
3: If the ACEA A5 engine oil is not available in your country, you are able to use API
SM & ILSAC GF4 (or above) or ACEA A3.
*
4: If the API SM & ILSAC GF-4 engine oil is not available in your country, you are able
to use API SL & ILSAC GF-3.
*
5: If the front/rear differential is submerged, we recommend that you visit an author-
ized retailer of Genesis Branded products to replace differential oil.

Recommended SAE Viscosity Number
Always 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 weath-
er operating (engine start and engine oil flowability). Lower viscosity engine
oils can provide better fuel economy and cold weather performance, howev-
er, 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 temper-
ature your vehicle will be operated in before the next oil change. Proceed to
select the recommended oil viscosity from the chart.
NOTICE
*1: For better fuel economy, it is recommended to use the engine oil of a viscosity
grade SAE 5W-30 (ACEA A5). However, if the engine oil is not available in your
country, select the proper engine oil using the engine oil viscosity chart.
*
2: For better fuel economy, it is recommended to use the engine oil of a viscosity
grade SAE 5W-20 (API SM / ILSAC GF-4
(or above)). However, if the engine oil is not available in your country, select the
proper engine oil using the engine oil viscosity chart.
