Engine Oil - Cub Cadet Challenger 500 Operator's Manual

WARNING
POTENTIAL HAZARD
Improper care when refueling.
WHAT CAN HAPPEN
Fuel can spill, which can cause a fire and
severe injury. Fuel expands when it heats
up. If the fuel tank is overfilled, fuel could
spill out due to heat from the engine or the
sun.
HOW TO AVOID THE HAZARD
Do not overfill the fuel tank. Be careful not
to spill fuel, especially on the engine or
exhaust pipe. Wipe up any spilled fuel
immediately. Be sure the fuel tank cap is
closed securely.
Pre Operation Checks

Engine oil

Make sure the engine oil is at the specified level.
Add oil as necessary. (See pages 8-12)
CAUTION:
 In order to prevent clutch slippage
(since the engine oil also lubricates the
clutch), do not mix any chemical
additives. Do not use oils with a diesel
specification of "CD" or oils of a
higher quality than specified. In addition,
do not use oils labeled
"ENERGYCONSERVING II" or
higher.
 Make sure that no foreign material
enters the crankcase.
