Owner Maintenance
Engine oil viscosity, or thickness, has an effect on fuel economy and cold-weather operation
(starting and oil fl ow).
Low-viscosity engine oils can provide improved fuel economy and cold-weather
performance.
When choosing an oil, consider the temperature range your vehicle will operate in before
the next oil change.
Then select the recommended viscosity from the chart.
Using oils of viscosity besides those recommended for specifi c temperature ranges could
result in engine damage.
NOTE
It is normal for all engines to consume engine oil under normal driving conditions.
Engine oil consumption may be as high as 0.8 L/1000 km (1 L/800 miles). This may be as
a result of evaporation, internal ventilation or burning of the lubricating oil in the working
engine. Oil consumption may be higher when the engine is new due to the running-in
process. Oil consumption is also dependant on engine speed and engine load. Under
extreme driving conditions, oil consumption may be higher.
