GENERAL FUEL, COOLANT AND LUBRICANTS ENGINE OIL SPECIFICATIONS Normal operation While SAE 15W-40 multi-viscosity oil is recommended for most operating climates, refer to Oil performance recommendations are as follows: the previous chart for oil viscosity recommendations The use of a quality engine lubricating oil combined with appropriate oil and filter change intervals are Single graded oils may be used if multi-graded oil is critical factors in maintaining engine performance and not available. But be sure to use oil that matches the durability. temperature shown in the table. for extreme climates.
SAE 15W-40 multi-viscosity oil meeting the American Special break-in lubricating oils are not Petroleum Institute (API) performance classification recommended for a new or rebuilt engine. Use the of CF-4 or CF-4/SG is recommended. same type of oil during the break-in as specified for CE or CE/SF oils may be used in areas where CF-4 or CF-4/SG oil is not yet available. Additional information regarding lubricating oil normal operation. availability throughout the world is available in the A sulfated ash limit of 1.0 mass percent is suggested "E.M.A. Lubricating Oils Data Book for Automotive for optimum valve and piston deposit and oil and Industrial Engines".

Higher ash oils can cause valve and/or piston Arctic Operation damage and lead to excessive oil consumption. The API service symbol displays the following consistently below -23 E C (-10 E F) and there are no information.
The upper half of the symbol displays provisions to keep the engine warm when it is not in the appropriate oil categories; the lower half may operation, use a synthetic API performance contain words to describe oil energy conserving classification CE or CF-4 engine oil with adequate features. The center section identifies the SAE oil low temperature properties such as SAE 5W-20 or viscosity grade. 5W-30. If an engine is operated in ambient temperatures Oil viscosity recommendations are as follows:
The oil supplier must be responsible for meeting the The use of a multi-graded lubricating oil has been found to improve oil consumption control and The use of a synthetic base oil does not justify improve engine cranking in cold temperatures while extended oil change intervals. Extended oil change maintaining lubrication at high operating intervals can decrease engine life due to factors such as; temperatures. corrosion, deposits and wear. performance service specifications. 01-8
