Oil and Maintenance Guide for 1998 Suzuki LT80 QuadSport 80
Before You Service the Engine
For the 1998 Suzuki LT80 QuadSport 80, identify the correct two-stroke lubricant and confirm how the engine receives its oil. Follow the correct model-specific instructions; two-stroke engine oil is not interchangeable with ordinary four-stroke crankcase oil.
What oil weight does a 1998 Suzuki LT80 QuadSport 80 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.
Does a two-stroke ATV always require premixed fuel?
No. Two-stroke engines may use premixed fuel or a separate oil-injection system. The oil-product listing alone does not establish which arrangement this particular ATV uses or what mixture ratio is required.
Why is two-stroke oil different from four-stroke engine oil?
Two-stroke oil is formulated for engines that lubricate internal parts differently from a typical four-stroke engine. The correct oil must suit the two-stroke lubrication system; four-stroke crankcase oil is not an interchangeable substitute.
