How often should you change oil in 2004 Audi A4?

According to the owner's manual for the 2004 Audi A4, the oil should be changed every 10,000 miles or every 12 months, whichever comes first. However, if the vehicle is driven in severe conditions, such as:

* Stop-and-go traffic

* Dusty or dirty roads

* Extreme temperatures

* Towing a trailer

Then the oil should be changed more frequently, every 5,000 miles or every 6 months.

It is also important to check the oil level regularly, and add oil if necessary. The oil level should be checked when the engine is cold and the vehicle is on level ground. The oil level should be between the "MIN" and "MAX" marks on the oil dipstick.

If you have any questions about changing the oil in your 2004 Audi A4, you can consult with your local Audi dealer.
