This needs to be inspected as soon as possible or the car might explode. You could experience bad gas mileage. Your oil needs to be replaced eventually. Every 5,000 to 10,000 miles is a good rule of thumb. If You don't replace it, there will be issues with the engine.

The 2008 Buick Enclave owner's manual recommends SAE 5W-30 as best oil for the vehicle, but you can also use an oil that meets GM Standard GM6094M. In areas of extreme cold, where the temperature falls below 20°F (29°C), it is recommended to use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil.
