Is Audi a3 expensive to maintain? How much is it once?

If Audi a3 is maintained in a 4s shop, it will not be cheap once. Basically, it is more than 1 100, and the original engine oil parts are used. If you want to use it well, it is more expensive. Personally, I don't think it is very cost-effective. I want to maintain an affordable point. Now I use German GT engine oil, which is imported from high-end. The quality and effect are much better than those of the original ordinary synthetic engine oil. Grade ⅳ PAO base oil has good quality, strong anti-aging ability and long maintenance mileage. Liquid molybdenum additive can lubricate and protect all parts of the engine well. Before driving, the car is much lighter in high temperature.
