The engine block heater may need to be plugged in 2 to 3 hours prior to
starting. The engine block heater is rated at 1500 watts, 110 Volts AC and
requires the motorhome be plugged into shore power or have the generator
running. It is not necessary to leave the block heater plugged in for long peri-
ods of time. The block heater requires about 13 amps to operate.
The maintenance guidelines found in the Cummins O & M manual is
recommended for the engine. When followed it will help with a longer
life, better performance and more cost efficient operations. A good main-
tenance schedule begins with a daily awareness of the engine and its vari-
ous systems.
A high grade 15W-40 multiviscosity heavy duty lubricating oil meet-
ing Cummins Engineering Specification CES 20071 or CES 20076,
American Petroleum Institute (API) specification CH-4 which can be
used as an alternative to CES 20071 is recommended. Lubricating oils
meeting API CG-4 specifications may be used at a reduced drain interval.
Monaco Coach uses Pennzoil 15W-40 heavy duty engine lubricating oil
that meets Cummins specifications. A critical factor in maintaining engine
performance and durability is the use of high grade multigrade lubricating
oil and strict adherence to the maintenance service intervals.
A straight weight or monograde lubricating oil is not recommended.
Shortened drain intervals may be required as determined by a close moni-
toring of the lubricating oil condition by means of a oil sampling pro-
gram. The use of oil analysis to extend drain interval is not recommend-
ed. There are numerous variables which is the basis of the recommenda-
tion.
Synthetic oils API category III specifications are recommended for
extreme cold temperatures only.
Low viscosity oils used for winter operations will aid in starting.
Synthetic oils or oil with adequate low temperature properties used for
Arctic operations, where the engine can not be kept warm when shut
down, will aid in starting.
The use of synthetic oils should not be used to extend drain intervals.
Extended oil change intervals can decrease engine life and possibly affect
the engine warranty.
Oil additives should not be used unless the oil supplier or oil manufac-
turer has been consulted and provided positive evidence or data establish-
ing satisfactory performance in the engine.
Oil Function of Engine Oil:
If a lubricating oil is to work in an engine it must be capable to per-
form various functions. Lubrication of the moving parts is the primary
function. The lubricating oil should be able to form a film between metal
