Which brand of engine oil is used in the Audi Q3?
2 Answers
Audi Q3 uses Castrol engine oil, which is SM-grade 5W40 oil. The functions of engine oil are: 1. Reduce wear between the piston and cylinder, as well as between the main shaft and bearing bush, providing lubrication; 2. Assist in cooling the engine internally; 3. Clean carbon deposits, sludge, and metal particle impurities from engine components; 4. Reduce gas leakage and prevent external pollutants from entering; 5. Absorb shocks and cushion the load on the piston, piston pin, connecting rod, and crankshaft bearings. Taking the 2021 Audi Q3 as an example, it belongs to the compact SUV category, with body dimensions of: length 4495mm, width 1848mm, height 1616mm, a wheelbase of 2680mm, a fuel tank capacity of 60 liters, and a trunk capacity of 450 liters.
I drive an Audi Q3, a 2018 model, and I enjoy doing my own maintenance. When choosing an engine oil brand, I always refer to the owner's manual first, which recommends using oils with VW 502 00 or VW 504 00 specifications to protect the engine from rust and wear. Commonly used brands include Audi's genuine oil and Castrol. Most of the 4S shops near my home use Castrol, and I've tried it myself with good results—it doesn’t make any clanking noises during cold starts in winter. If genuine oil isn’t available, synthetic oils from Mobil or Shell are also compatible and more affordable, but don’t skip oil change intervals just to save money. I usually check every 8,000 kilometers. Remember to choose 5W-30 viscosity for better high-temperature sludge protection and to avoid black smoke from the exhaust due to oil burning. In short, don’t randomly switch brands—ensure the certification specifications match to save on major repair costs.
