The oil level should be between the "L" and "F" marks on the level gauge. If low, check for leakage and add oil up to the "F" mark. If low, check for leakage and add oil up to the full level marks.
NOTE:
- When inserting the oil dipstick, insert the curved tip of the dipstick facing the same direction as the curve of the guide.
- If the dipstick gets caught while inserting it, do not force it in. Reconfirm the direction of the dipstick.
