What is the best engine oil for Audi Q3?
2 Answers
Audi Q3 is recommended to use the original factory oil, which is Audi's original fully synthetic SM grade 5W-40 engine oil. The 1.4T model requires 4L, while the 2.0T model requires 5L. According to the 4S shop's recommendation, the oil should be changed every 5,000 kilometers, while the official recommendation is every 10,000 kilometers. Below is an introduction to the engine oil specifications: 1. "W" stands for WINTER, and the number before "W" represents the viscosity in low-temperature conditions. The smaller this number, the better the low-temperature fluidity of the oil, providing better engine protection during cold starts. 2. The number after "W" represents the viscosity of the oil at 100°C. The higher the number, the higher the viscosity, which provides better engine protection at high temperatures. Engine oil, also known as engine lubricant, is referred to as the "blood" of a car. It lubricates, cleans, cools, seals, reduces friction, prevents rust, and protects against corrosion in the engine. The engine is the heart of a car, containing many metal surfaces that move against each other at high speeds in harsh environments, with working temperatures ranging from 400°C to 600°C. Under such extreme conditions, only qualified lubricants can reduce engine component wear and extend service life. Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, providing new properties and serving as an important part of the lubricant.
My Audi Q3 has been running for almost five years now, and I pay special attention to oil changes. The manual emphasizes using fully synthetic oil that meets the VW 508 00 certification, with 0W-20 viscosity being the mainstream recommendation. I've used Shell's Edge fully synthetic oil, and it makes the engine run quieter and smoother, especially during cold starts in winter, which no longer feels labored. Castrol Edge is also a great fit for Audis, offering excellent long-term protection and can last up to 10,000 kilometers or a year. Don’t skimp by using mineral oil—the Q3’s engine is a bit delicate, and while fully synthetic is pricier, it’s worry-free and more fuel-efficient. Also, consider the season: 0W-20 flows better in cold climates, while 5W-30 is better for high temperatures to avoid wear. Every time I change the oil, I also check the air filter—it’s efficient and safe. Regular maintenance can extend your car’s lifespan. Hope this helps!
