Specifications - Cub Cadet RZT 42 Operator's Manual

Do not add oil to the gasoline.
Do not overfill the fuel tank. Leave room for the fuel to
expand.
Fuel Type
For best results use only clean, fresh, unleaded
gasoline with a pump sticker octane rating of 87 or
higher. In countries using the Research method, it
should be 90 octane minimum.
Unleaded gasoline is recommended as it leaves less
combustion chamber deposits. Leaded gasoline may
be used in areas where unleaded is not available and
exhaust emissions are not regulated. Be aware
however, that the cylinder heads may require more
frequent service.
Gasoline/Alcohol blends
Gasohol (up to 10% ethyl alcohol, 90% unleaded
gasoline by volume) is approved as a fuel for Kohler
engines. Other gasoline/alcohol blends are not
approved.
Gasoline/Ether blends
Methyl Tertiary Butyl Ether (MTBE) and unleaded
gasoline blends (up to a maximum of 15% MTBE by
volume) are approved as a fuel for Kohler engine.
Other gasoline/ether blends are not approved.
Engine Identification Numbers
When ordering parts, or in any communication
involving an engine, always give the Model,
Specification, and Serial Numbers of the engine.
The engine identification numbers appear on a decal
affixed to the engine shrouding. Include letter suffixes,
if there are any.
Record your engine identification numbers on the
identification label (Figure 4) for future reference.
