4-3. Do-it-yourself maintenance
Add oil based on the oil level shown on the meter.
Do not add more than 0.5 qt. (0.5 L, 0.4 Imp. qt.) at a time regardless of
the oil level reading.
To check the oil level again, install the oil filler cap by turning it
clockwise.
Check the oil level using the “Oil Level” display and repeat the
above procedure if more oil is required.
Even if the measurement result shows that the oil is below the maximum
level, be careful not to add more oil than necessary.
Install the oil filler cap by turning it clockwise.
■Engine oil consumption
●The amount of engine oil consumed depe nds on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds and fre-
quent acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumpt ion, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
●Oil consumption: Max. 1.1 qt./600 miles (0.9 Imp. qt./600 miles, 1.0 L/1000
km)
●If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Lexus dealer.
■After the engine oil has been changed
The “Oil Maintenance” display on the mete r needs resetting. Have the display reset
at your Lexus dealer. ( P. 1 3 2 )

Lubrication system■ Specified engine oil for the LFA
*1: The oil filters used are exclusive to the LFA. When the oil is changed, the oil fil-
ters should also be replaced.
*
2: The lifetime of the vehicle depends greatly on the quality of oil used. The use of “Mobil 1 5W-50” is most suitable for your vehicle and is recommended.

■Engine oil viscosity
●The 5W portion of the oil viscosity rating
indicates the characteristic of the oil
which allows cold startability. Oils with a lower value before the W allow for eas-
ier starting of the engine in cold weather.
●The 50 in 5W-50 indicates the oil viscosit y when the oil is at its operating tem-
perature. An oil with a higher viscosity may be better suited if the vehicle is
operated at high speeds, or under extreme load conditions.
NOTICE
■To prevent engine damage
If “Mobil 1 5W-50” is not available, another oil of equivalent quality to “Mobil 1
5W-50” may be used. In this case, do not start the engine if the engine coolant or
oil temperature is below 5 F (-15C), and do not drive the vehicle under extreme
load conditions.
