  • Funnel
  • New oil filter
  • 4-stroke engine oil (10W-40 recommended)

Steps to Change the Oil

1. Warm Up the Engine

Start the engine and let it run for a few minutes. This helps the oil to flow out smoothly when you drain it.

2. Locate the Drain Plug

The drain plug is located at the bottom of the engine. Place the drain pan underneath to catch the old oil.

3. Remove the Drain Plug

Using a socket wrench, carefully remove the drain plug. Allow the oil to completely drain into the pan.

4. Replace the Oil Filter

Use the oil filter wrench to remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the filter. This ensures a proper seal.

5. Reinstall the Drain Plug

Once the oil has fully drained, reinstall the drain plug securely.

6. Add New Oil

Using a funnel, pour the new oil into the engine. The 1987 Suzuki LT185 QuadRunner typically requires about 1.6 quarts of oil. Check the oil level with the dipstick to ensure it's at the correct level.

7. Check for Leaks

Start the engine and let it run for a few minutes. Check around the oil filter and drain plug for any leaks. Tighten if necessary.
