• Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When to Add Engine Oil” in this section.
• Change the engine oil at the appropriate time. See Engine Oil Life System.
• Always dispose of engine oil properly. See “What to Do with Used Oil” in this section.
