Oil and Maintenance Guide for 2004 Suzuki LT80 QuadSport 80
Before You Service the Engine
The 2004 Suzuki LT80 QuadSport 80 uses a two-stroke oil application; verify the required product and oil-delivery system before adding lubricant. Follow the correct model-specific instructions; two-stroke engine oil is not interchangeable with ordinary four-stroke crankcase oil.
What kind of oil does a 2004 Suzuki LT80 QuadSport 80 take?
The engine-oil viscosity shown for this model is 10W-40. The available oil-product listings include DOMINATOR® Synthetic 2-Stroke Racing Oil, 10W-40 Synthetic ATV/UTV Engine Oil. For a service, choose oil that meets the engine’s actual application requirements, not just a product name.
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.
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.
