Caution
Do not overfill with engine oil.

Check the engine oil with the engine positioned horizontally.

Used engine oil can cause skin cancer if repeatedly left in contact with skin for prolonged periods. Although this is unlikely unless you handle used oil on a daily basis, it is still advisable to thoroughly wash your hands with soap and water as soon as possible after handling used motor oil.
