Oil and Maintenance Guide for 1999 Kawasaki 250 Mojave 250
Before You Service the Engine
For the 1999 Kawasaki 250 Mojave 250, planning an engine service involves checking the correct lubricant application and following the proper refill procedure. Before removing the drain plug, identify the correct refill and level-check procedure; a published capacity does not necessarily equal the amount needed after a routine drain.
What oil weight does a 1999 Kawasaki 250 Mojave 250 need?
The oil grade identified for this model is 10W-40. Viscosity is only one part of selecting oil: the product must also meet the engine’s applicable specifications.
How much oil does a 1999 Kawasaki 250 Mojave 250 take?
The available engine-oil capacity figure is 2.11 quarts. The amount added during a routine drain may differ from the listed capacity; use the correct level-check procedure when refilling.
Does using synthetic oil change the viscosity grade an ATV needs?
No. Synthetic describes how the oil is formulated; it is separate from the SAE viscosity grade. A synthetic oil still needs the appropriate grade and engine-application specifications.
Why does four-stroke engine oil need the right application rating?
Engine oils differ in additive packages and friction characteristics. Some powersports engines share oil with a wet clutch or transmission, so matching the manufacturer’s oil requirements matters in addition to viscosity. This listing does not by itself confirm the clutch design.
