Best oil for Audi A4: Buying Guide

Before making a buying decision, it’s good to know what to look for to ensure you are getting value for your money. Cars like the Audi A4 have engines that need good maintenance to ensure it runs efficiently.

This requires buying the best oil for the Audi A4 that will take care of deposits and sludge to ensure engine performance is never compromised.

Always observe routine oil changes as specified in the car owner’s manual and product manufacturer recommendations. 

High mileage

Modern Audi A4s can last longer. So, opt for high-mileage oils. Also, if you own a used Audi A4 it’s best to buy high-mileage engine oil. We recommend it for people who have cars that clocked at least 100,000 miles.  

Extreme driving conditions

When talking about extreme conditions, it means your driving habits. Some drivers shift gears and apply heavy braking at high speeds. Also, some drivers use their Audi A4 in cold or hot temperature regions.

All these conditions affect your Audi A4 engine. You may need to change your oil every 5000 miles to maintain optimal engine performance. 

Car oil consumption

Perhaps your Audi is burning oil. This issue is easily controlled by tracing the oil pressure. Your Audi A4 has an oil pressure sensor, know where it’s located from your owner’s manual. Determine your car’s oil consumption.

When you bought it, you were advised to change the oil after 6000 miles or six months whichever comes first.

Normally, oil changes happen after clocking 3000 or 4000 miles. At this time, your Audi is in the normal break-in period. For older Audi, change the oil after it clocks 6000 miles. Strive to limit oil burning as it results in more engine wear. 

In-between oil change

Let six months pass of the car clock the specified miles before you make your first oil change. Why? As your car gets older, the engine accumulates more sludge and deposits. With time, these deposits cause engine wear. 

To be safe, constantly check the oil level after the stated period to ensure your engine runs smoothly with no overheating problems. Remember, the oil must remain clean to allow those engine components to work smoothly without any friction concerns.

Viscosity

Resistance of your oil to flow is a vital consideration when buying. The number 5W-40 is a viscosity rating. The 5W means a low-temperature rating with the “W” representing winter. The second part in this case 40 is a high-temperature rating.

Normally the engine oil gets thicker in low temperatures and thinner in high temperatures.

Your oil choice should have a good amount of additives to ensure it can lubricate the engine even in cold conditions. The number 5 in the 5W represents resistivity at low temperatures. In this case, it means the oil remains fluent at 5 Fahrenheit and thins at 40 Fahrenheit. 

Oil Brand

Oil brand has less impact on the oil choice. Why? Because every oil brand has an objective specification in its oil composition.

This guides you to know which oil to avoid based on their compatibility with your Audi A4 and engine type. You are safer disregarding subjective measures like the brand because existing product and car manufacturer partnerships may advise you to only opt for certain brands.

The truth is that it’s not necessary to follow brand recommendations as long as the oil is suitable for your Audi A4 engine.

Oil Additives

As your Audi A4 engine ages, you have to deal with external elements that can have symptoms like engine noise. Most experts advise treating your engine with oil additives to address these issues and curb engine wear.

Pick an oil with friction modifiers to improve fuel economy and reduce friction. Ensure the oil has antioxidants to boost emission control and prevent oxidation.

Check to see if there are foam inhibitors to prevent sludge formation. Rust inhibitors prevent corrosion. 

Synthetic Oil 

5W-40 oil is adapted to the Audi A4 engine. Besides, the oil offers maximum engine protection and drivers can cold start the engine without problems.

Synthetic oil is highly preferred when driving long distances, in city centers or simply wanting to reduce oil change frequency. 

Cost

Price is always a factor in buying decisions, and Audi A4 oil is no different. Pick an affordable Audi oil that gives you the same great benefits for optimal engine performance and efficiency.

The cost depends on the type of oil. Compare the prices and the features of each oil in the list reviewed above and make a wise choice.

Whichever Audi oil you pick, expect wonderful results and efficient engine performance.

Oil Quality

Always pick an oil that does more for your Audi A4 engine and meets the quality standards. For instance, the oil prevents sludge and deposit formation and reduces friction and wear.

This means you solve multiple problems at once with your oil choice.
