Question
How do you check and fill engine oil with a four-stroke model? (Video)
 
Answer
 
 

Follow the steps below for filling and checking your oil level on all four-stroke models (excludes F2.5 and F4 models).

1. Fill the engine with 2/3 of the recommended oil capacity from your Owner’s Manual. The engine will retain oil and not be able to drain completely. Using 2/3 of oil capacity is to prevent over filling.

2. Add oil only at the specified location which is designated by a yellow filler cap.

3. Remove the dipstick and wipe with a dry rag, then reinsert the dipstick.

4. Remove the dipstick again and now verify the oil level. Do not exceed the half way point on the crosshatch marks.

 
5. If you are not within the crosshatch marks on the dipstick, add more oil. Be aware that the engine pan is tapered at the top. This means the oil pan gets skinnier at the top and fatter at the base. So as you get closer to the full point, the oil will rise faster on the dipstick.

6. If it is above the halfway point on the crosshatched dipstick then some oil will need to be drained.

7. To verify that the oil level is correct, run the engine at idle until the operating temperature has been reached (approx 10 minutes). Then, shut off the engine and trim it half way into the tilt range. Allow the engine to sit in this position for five minutes before leveling the engine and rechecking the oil level.

8. Repeat steps 2-6 until you have the proper oil level.

Note: Always use a new washer-shaped metal gasket for your oil pan drain screw. The gasket is crushed when the drain screw is tightened and should not be reused.
