Duracell DG66M-R62 Owner's Manual page 30

Take into account the total requirements of all appliances, tools, and other electrical devices
powered by your generator when considering requirements and limits.
Estimate the amount of surge (i.e. starting) watts needed for each electrical device that you plug
into your generator. The surge wattage is the short burst of power needed to start these tools,
appliances, and other electrical devices.
5. Fuel requirements
Use only high quality unleaded gasoline to help minimize combustion chamber deposits.
Use only clean gasoline and oil. Never use gasoline or oil that is stale, contaminated, or poor
quality. This could damage your generator's engine. Keep your fuel tank and oil cup clear of
impurities (e.g. dirt, dust, water).
6. Use only the recommended fuel
Please refer to the engine owner's manual for the recommended type of fuel and follow these
recommendations in order to comply with the warranty requirements. Failure to follow the engine
owner's manual may void the engine warranty.
7. Use only the recommended engine oil
Please refer to the engine owner's manual for the recommended type and quantity of engine oil
and follow these recommendations in order to comply with the warranty requirements. Failure to
follow the engine owner's manual may void the engine warranty.
Although there is a "low oil warning" indicator that will warn you when the oil level is critically low
this is not for maintenance, it is a warning indicator of a problem. It is recommended that you
check the oil level routinely to ensure that the engine has sufficient oil at all times.
Do not run your generator without oil. This would damage the engine and void your warranty.
