What kind of oil should be added to an Audi A4?

Audi A4 should use 0W40 fully synthetic oil or 5W40 fully synthetic oil. Engine oil, also known as motor lubricant, is composed of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while the additives can compensate for and improve the shortcomings of the base oil's performance. The Audi A4 is a mid-size sedan with a body structure of 4 doors and 5 seats. Its dimensions are 4858mm in length, 1847mm in width, and 1439mm in height, with a wheelbase of 2908mm. In terms of power, this car is equipped with three types of engines: a low-power version 2.0-liter turbocharged engine, a medium-power version 2.0-liter turbocharged engine, and a high-power version 2.0-liter turbocharged engine.
I always use fully synthetic oil for my Audi A4, generally recommending models that meet Volkswagen VW 502 00 or 504 00 standards, such as 0W-20 or 5W-30, with viscosity determined by the year. My 2019 model uses 0W-20 because the manual clearly states it improves fuel efficiency, making the engine quieter and more fuel-efficient. Don’t skimp by using mineral oil or inferior products, as they can lead to carbon buildup and shorten engine life. During every maintenance session, I personally check the oil level—using the dipstick to see if it’s between Min and Max, topping it up promptly if it’s low. Extra attention is needed during summer heat when oil can become too thin, leading to insufficient lubrication. It’s best to choose reputable brands like Shell or Mobil, and always verify certification labels before purchasing online. In short, engine oil is the lifeblood of a car; choosing the right one keeps the A4 running like new for a decade, saving both money and hassle.
As a long-time A4 owner, I believe the key to choosing engine oil lies in matching the engine's requirements. Audi models typically require full synthetic oil, with the VW 504 00 standard being optimal, especially for newer models that use 0W-20 viscosity, ensuring stable performance in both low and high temperatures. I once used the wrong oil and noticed a 3% increase in fuel consumption, but after switching back to the recommended oil, engine noise significantly decreased. I recommend checking the dipstick before driving to ensure the oil level is within the normal range, with an ideal oil change interval of every six months or 10,000 kilometers. For modified cars, don't cut corners—oil viscosity that's too low can lead to insufficient oil pumping. Remember, good engine oil enhances overall performance, making driving smoother and more environmentally friendly.
