1. Park the quad on level ground and turn off the engine.
2. Allow the engine to cool down for a few minutes.
3. Locate the oil sight glass on the left side of the engine, near the bottom.
4. Clean the oil sight glass with a rag to ensure a clear view.
5. Stand on the left side of the quad and look at the oil sight glass.
6. The oil level should be between the "F" and "L" marks on the sight glass.
If the oil level is low, add enough oil to bring it up to the "F" mark. Use only SAE 10W-40 motor oil.
7. Replace the oil fill cap and tighten it securely.
You should check the oil level in your Suzuki QuadRunner 250 before each ride. If the oil level is low, it can damage the engine.
