For the 2020 model 330 Meiyan version, should I use the 0-20 oil from the 4S shop or buy other oil myself for better performance?

VW is affordable and practical.

The oil provided by 4S shops is called custom oil, which is actually downgraded oil. It has lower quality, higher fuel consumption, more noise, and less power. If you know what you're doing, get it from outside; if not, find a friend who understands cars to guide you on maintenance. Car maintenance isn't just about engine oil—transmission fluid and antifreeze are also very important. If you're clueless, you might have to rely on 4S, but if you want proper maintenance, you should step out of the 4S, consult someone or hire an advisor! You'll definitely save a lot. Using good oil saves fuel, keeps the car in good condition, and makes it easy to drive. Just in terms of fuel savings, it could save you around 800 yuan per 10,000 kilometers!

The engine oil from the 4S shop is sufficient, as long as it's fully synthetic.
