◆ 1.5.3 ENGINE OIL REQUIREMENTS

Use a high-quality detergent oil with American Petroleum Institute (API) classification “For Service CC.” Detergent oils keep the engine cleaner and reduce carbon deposits. Use oil having the following SAE viscosity rating, based on the ambient tempera- ture range anticipated before the next oil change:

Temperature	Oil Grade (Recommended)
Above 100º F (38º C)	SAE 15W-40* or SAE 40
40º to 100º F (4.4º to 38º C)	SAE 10W-30 or SAE 30
Below 40º F (4.4º C)	SAE 5W-20 or 5W-30

* - in units from the factory

Crankcase and oil filter capacity is approximately 3.5 L or 3.7 U.S. quarts. Do NOT use special additives. See Sections 3.1 and 3.2 for oil level checking and changing procedures.

◆1.5.4 COOLANT

Use a 50:50 mixture that is half low silicate, ethylene glycol base antifreeze and half soft water. Use only soft water and only low silicate antifreeze. If desired, a high-quality rust inhibitor to the recommended coolant mixture may be added. When adding coolant, always add the recommended 50-50 mixture.

DANGER

Do not remove the radiator pressure cap while ! the engine is hot; otherwise, serious burns

from boiling liquid or steam could result.

Ethylene glycol base antifreeze is poisonous. ! Do not use mouth to siphon coolant from the

radiator, recovery bottle, or any container. Wash hands thoroughly after handling. Never store used antifreeze in an open container because animals are attracted to the smell and taste of antifreeze, even though it is poisonous to them.

Do not use any chromate base rust inhibitor ! with ethylene glycol base antifreeze; or else,

chromium hydroxide (“green slime”) will form and cause overheating. Engines that have been operated with a chromate base rust inhibitor must be chemically cleaned before adding eth- ylene glycol base antifreeze. Using any high-sil- icate antifreeze boosters or additives will also cause overheating. DO NOT use any soluble oil inhibitor for this equipment.
