The typical oil capacity for the 2018 Audi A4 2.0 TFSI, including a new filter, is about 4.4 quarts (roughly 4.2 liters). Exact amounts can vary slightly by engine code and drivetrain configuration, so it’s best to confirm with the owner's manual or by checking the dipstick during a fill.
Official capacity and practical considerations
Understanding the official specification helps when planning an oil change, but real-world filling should be guided by the dipstick reading and service notes. The 2.0 TFSI engine used in the 2018 A4 generally aligns with a ~4.4-quart capacity when the filter is replaced, though small regional or engine-code differences can cause minor variations.
The following summary highlights the typical capacity and factors that may influence the exact amount you’ll need.
- Typical capacity (including oil filter): approximately 4.4 quarts (4.2 liters).
- Engine code and drivetrain differences (e.g., front-wheel drive vs. quattro) can cause small variations in the final fill amount.
- Oil type and climate can affect how you reach the correct level; always verify the dipstick reading after filling.
When in doubt, start with the approximate capacity and add oil in small increments, rechecking with the dipstick to avoid overfilling.
How to check and fill the oil
To ensure you reach the correct level after replacing the oil and filter, follow these standard steps. The goal is to arrive at the middle of the acceptable dipstick range for an optimal level.
- Park on level ground and turn off the engine. Allow the engine to cool for several minutes if it’s a hot-change scenario, or wait until it’s warm if you’re topping up after driving.
- Open the hood and locate the oil filler cap and dipstick. Remove the dipstick, wipe it clean, and reinsert it fully; then pull it out again to check the current level.
- Using a clean funnel, add oil in small increments (about 0.25 quart or 0.25 liter at a time), noting the approximate level on the dipstick after a brief stationary period.
- Continue adding and rechecking until the dipstick shows the oil level between the Min and Max marks, ideally near the middle of that range.
- Replace the oil filler cap securely, start the engine, and run it for a couple of minutes to circulate the new oil. Turn off the engine and recheck the level once it’s cooled slightly.
- Record the total oil added for future reference and ensure the oil type matches the manufacturer’s specification (commonly 5W-40 in many markets, but verify for your region).
Following these steps helps ensure you meet the recommended capacity without risking overfill or underfill.
Summary
For a 2018 Audi A4 2.0 TFSI, the typical oil capacity is about 4.4 quarts (4.2 liters) when changing the oil with a new filter. Exact amounts can vary by engine code and drivetrain, so always confirm with the owner’s manual and use the dipstick to finalize the level. When in doubt, start with the approximate capacity and top up gradually while monitoring the dipstick.
