Gasoline Engine
To achieve proper engine performance and durability, it is
important that only the correct type of engine oil be used in
the engine. Quality oil provides maximum efficiency for
crankcase ventilation systems, which reduces pollution.
NOTE:
Use only engine oils displaying the American
Petroleum Institute (APA) Starburst Certification
Mark
FOR GASOLINE ENGINE
on the container.
Gasoline engines that are converted for Liquid Propane Gas
or Natural Gas fuel
MUST
use oils labeled
FOR GASOLINE
ENGINE
. Do not use oils that are specifically formulated for
Diesel Engines only. CC or CD classification oils, even when
labeled Heavy Duty or for Natural Gas Engines,
ARE NOT
ACCEPTABLE
.
Engine Oil Recommendation
Multi-viscosity oils are recommended, SAE 10W-30 is
recommended from 0
°
F (-18
°
C) or above. If ambient
temperatures are consistently below 0
°
F (-18
°
C), SAE 5W-
30 oil should be used. Synthetic oils are not recommended
for industrial engines.
FUEL TYPES
Diesel Fuel
The Cummins Diesel Engine operates most efficiently with
No. 2 diesel fuel in temperatures above 32°F (0°C). When
operating in temperatures below 32°F (0°C), use No. 1 diesel
fuel, or a blend of No. 1 and No. 2 diesel fuels, most
commonly known as “Winterized” No. 2 diesel. Use ASTM
No. 2 diesel fuel with a minimum Cetane number of 40. No. 2
diesel fuel gives the best economy and performance under
most operating conditions. Fuels with Cetane numbers
higher than 40 may be needed in high altitudes or extremely
low ambient temperatures to prevent misfires and excessive
smoke.
Gasoline
The GMC gasoline engine operates only on lead-free
gasoline with the following minimum or higher octane ratings:
Anti-Knock Index Number (AKI) — 87
Research Octane Number (RON) — 91
NOTE:
The use of gasoline with a lower octane than
87 AKI (91 RON) octane will result in serious
damage to the engine. Engine damage resulting
from use of a low octane gasoline is considered
misuse of the engine and will void the engine
warranty and the crane warranty.
Many types of gasoline being sold today contain alcohol.
Two commonly used alcohol additives are Ethanol and
Methanol.
