Mazda 6 Service Manual: Engine oil replacement

Warning

• Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the engine oil has cooled.

• A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall, causing death or serious injury. Never work around or under a lifted vehicle if it is not securely supported on safety stands.

• Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your skin by washing with soap and water immediately after working with engine oil.
