Onan Performer P220 User Manual

FUEL RECOMMENDATIONS
[Awarning I Gasoline and LPG are highly flam¬
mable fuels andean cause severe personal inju¬
ry or death. Do not smoke if you smell gas or
gasoline or are near fuel tanks or fuel-burning
equipment or are in an area sharing ventilation
with such equipment. Keep flames, sparks, pilot
lights, electrical arcs and arc-producing equip¬
ment and all other sources of ignition well away.
Keep a type ABC fire extinguisher nearby.
Gasoline Models
Use clean, fresh unleaded gasoline having a mini¬
mum octane rating (Anti-Knock index) of 87 .
During some times of the year only mandated “oxy¬
genated” gasolines may be available. These are ac¬
ceptable for use, but not preferable. Leaded gaso¬
line may be used but will result in the extra mainte¬
nance required for removing combustion chamber
and spark plug deposits. Do not use gasoline or
gasoline additives (de-icers) containing methanol
because methanol can be corrosive to fuel system
components.
percent propane. Commercial LPG may contain
more than 2.5 percent butane which can result in
poor fuel vaporization and poor engine starting in
low ambient temperatures (below 32 ° F ( 0 ° C).
Natural Gas Models
Use commercially available natural gas fuel.
ENGINE OIL RECOMMENDATIONS
Use premium quality motor oil. Look for the API
(American Petroleum Institute) classification and
use Class SG or SH oil (also SG/CD, SG/CE, SH/
CD or SH/CE). Also look for the SAE (Society of Au¬
tomotive Engineers) viscosity grade. Referring to
Table 1 , choose the viscosity grade appropriate for
the ambient temperatures expected during the peri¬
od of time until the next scheduled oil change.
Single-grade SAE 30 oil is preferable when temper¬
atures are consistently above freezing. Multigrade
oils are better when wide temperature variations are
expected.
IA caution I Do not use gasoline or gasoline ad¬
ditives containing methanol because methanol
can be corrosive to fuel system components.
Avoid using highly leaded gasolines and lead
additives because of the extra engine mainte¬
nance that will be required.
LPG Models
Use clean, fresh HD -5 grade liquified petroleum gas
(LPG) or equivalent product consisting of at least 90
