Select engine oil of the proper SAE viscosity number according to the at-mospheric temperature.Recommended viscosity is given inthe following illustration. The engine oil quality should meet the following API classification: 2.6 N/A : CF-4 or ABOVE 2.5 4D56 : CF-4 or ABOVE 2.5 CRDi : CF-4 or ABOVE The engine oil quality should meet the following ACEA classification: 2.6 N/A : B2 or B3 2.5 4D56 : B2 or B3 2.5 CRDi : B4 NOTE: For diesel-powered vehicle SAE 0W-30 oil should be used only inareas where extremely cold tem- peratures of 10°C (50°F) or below are experienced. For diesel-poweredvehicle, if the atmospheric tempera- tures are 0°C (32°F) or below, SAE 30 oil must not be used.

Recommended Oil Gasoline Engine
G030B01JMEngine oil is essential to the perfor-
mance and service of the engine. It is suggested that you check the oil level at least once a week in normal use and more often if you are on a trip ordriving in severe conditions.
The engine oil quality should meet the
following classification.
API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE NOTE:
o For good fuel economy, SAE 5W- 20 (5W-30), ILSAC GF-3 engine oil is preferred regardless of regional option and engine variation.
o If SAE 5W-20, ILSAC GF-3 engine oil is not available, secondaryrecommended engine oil for cor- responding temperature range can be used.
This oil should be used only inareas where the atmospheric tem-peratures are 0°C(32°F) or above.

10CHECKING THE ENGINE COOLANT
G350A01A-GAT ENGINE OIL CONSUMPTION Function of Engine Oil Engine oil has the primary function of lubricating and cooling the inside of the engine. Engine oil consumption It is normal that an engine should consume some engine oil while nor- mal driving. The cause of oil con- sumption in a normal engine are asfollows;
o Engine oil is used to lubricate pis-
tons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated dur-ing engine operation sucks some of the oil into the combustion cham- ber.This oil with some oil of the cylin-der wall is burned by the high tem-perature combustion gases during the combustion process. o The engine oil consumption is
strongly effected by the viscosity and quality of oil, engine rpm and driving condition etc. The engine oil is more consumed under severedriving conditions such as high speeds and frequent acceleration and deceleration than normal driv-ing condition. I080A02P-GAT
!WARNING:
Do not remove the radiator cap
when the engine is hot. When the engine is hot, the engine coolant is under pressure and may erupt through the opening if the cap isremoved. You could be seriously burned if you do not observe this precaution. Do not remove theradiator cap until the radiator is cool to the touch.
