Recommended Sae Viscosity Number - Hyundai i20 Owner's Manual

Vehicle information

Recommended SAE viscosity number

CAUTION
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 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.
