Keeping your car in top running condition is a must when you drive high-end, powerful models such as Audis. A standard practice to increase the life of your Audi engine is to give it an oil change every 7,500 miles. Cheaper vehicles require an oil change every 3,000 miles, but Audi high performance engines have better oil filtration systems that increase the life of the oil.
Park your Audi on a level spot.
Crawl under the Audi engine and locate the oil drain plug on the bottom, back side of the engine block. Fit the proper sized socket onto the drain plug bolt. The standard size of an Audi oil drain plug is 13mm. Unscrew the oil drain plug.
Position the oil drain pan under the oil drain plug hole. Let all the oil drain out. Screw the oil drain plug back into the engine block tightly.
Crawl out from under the Audi. Locate the oil fill lid on top of the engine. Several inches in front of the oil fill lid is the oil filter containment housing held down by a single nut on top. Unscrew the nut with the correct sized socket--the standard nut size is usually 24mm. Pull the oil filter containment housing off. Pull the old oil filter out and rub some of the oil on it around the top and bottom rubber seals on the new oil filter. Place the new oil filter in the area where the old one was located. Screw the oil filter containment housing back down.
Open the oil fill lid. Add seven quarts of oil to the Audi engine. Check the oil dipstick for the oil level. Add more oil as needed. Most Audis require around 7.5 quarts of oil. Replace the oil fill lid upon completion.
