What brand is the original Audi engine oil?

Audi's original factory-specific engine oil comes in two types: domestic and imported. The domestic engine oil is Audi's matching specialized oil, produced in Changchun City, Jilin Province, specifically designed for domestically produced vehicles. There is also a Castrol Edge Professional oil, primarily used for Audi imported vehicles. Below is relevant information about engine oil: 1. Mineral Oil: Mineral oil's base is derived from crude oil refining. After extracting gases, gasoline, diesel, kerosene, and heavy oil from crude oil, the mineral oil base is refined, leaving asphalt as the residue. The mineral oil base is transparent with a slight amber hue, similar to the color of salad oil. Typically, mineral oil is very low-cost, but because the mineral oil base oxidizes more easily, even though modern mineral oils contain various imported additives, their service life remains around six months. 2. Full Synthetic Oil: This oil contains only PAO or ester-based synthetic compounds, entirely manufactured chemically. Initially used in the aviation industry, it was later adopted in racing and is now widely used in passenger cars. The advantages of full synthetic oil include high cleanliness, excellent fluidity, superior cooling capability, and outstanding oxidation resistance. 3. Semi-Synthetic Oil: Semi-synthetic oil is a blend of synthetic oil and a portion of mineral oil, typically in a 4:6 ratio. It combines the benefits of full synthetic oil at a lower cost. While its performance is inferior to full synthetic oil, it is more affordable and has a slightly shorter replacement cycle compared to full synthetic oil.

I've been driving an Audi A6 for five years and always use genuine oil for maintenance, specifically the Castrol EDGE brand. The 4S dealership says this is Audi's officially recommended oil because it meets the engine requirements, offers better protection, reduces noise, and maintains stable fuel consumption. When changing the oil, I remind new owners to look for oil with VW 507 certification—avoid cheap off-brand oils, as they may cause engine wear or oil burning. Regular maintenance is crucial; I change the oil every 8,000 kilometers, which can extend the car's lifespan by several years. If buying online, make sure to purchase from reputable platforms like Tmall's flagship store to avoid counterfeit products. Overall, this oil is worry-free and reliable, and long-term Audi drivers highly recommend it.

As a technician who frequently repairs German cars, I have handled many Audi maintenance cases. The original engine oil often uses the Castrol series because it meets Audi's VW certification standards, such as 502 or 507, ensuring lubrication and cleaning power suitable for turbocharged systems. If the owner uses the wrong brand, it may cause oil leaks or high fuel consumption issues. I recommend always referring to the car manual when selecting engine oil. During maintenance, it's also necessary to check the oil condition and filter, replacing them regularly to avoid carbon buildup. The replacement frequency is generally every 7,500 to 10,000 kilometers, which can maximize engine performance. From a professional perspective, original Castrol is a trustworthy choice, but equivalent certified brands are also acceptable—the key is matching the specifications.

I just bought a used Audi Q3 and looked up the original engine oil brand online. The mainstream choice is Castrol. Many people in the discussion forums shared their experiences, mentioning that some model years use Total or other brands, but the key is to check the car manual for certifications like VW502. After comparing prices, I found that buying original oil at the dealership is slightly more expensive, but you can use budget-friendly alternatives with the same certification. DIY oil changes save money, but you must ensure you purchase genuine products and perform the filter replacement correctly. This oil offers many benefits, optimizing driving performance and being more environmentally friendly. The car owner groups emphasize not to switch brands randomly, as it can lead to engine issues. For me, choosing the right product is the most important.
