Why Oil Capacity Matters
Engine oil does more than just lubricate. It protects moving parts from wear, reduces friction, helps cool the engine, and prevents sludge buildup. Both overfilling and underfilling can harm your Audi’s engine.
- Overfilling Risks: Too much oil can cause foaming, higher pressure, and damage to seals.
- Underfilling Risks: Not enough oil leads to poor lubrication, increased friction, overheating, and potential engine failure.
Keeping your oil level at the correct capacity ensures optimal lubrication and long-term reliability.
