Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity
●5W oils are for use in areas where the ambient temperature is -3F (-25C) or
above. "10W" oils are for areas where the ambient temperature is -4
F (-20C)
or above. Oils with smaller figures are better for engine starting in cold weather
and fuel efficiency.
● XX-30 indicates oil viscosity. Oils with higher numbers have better sta-
bility at higher temperatures and are good for high-speed driving.
