What is the optimal amount of engine oil for an Audi A4?

Audi A4 requires 4.5 liters of engine oil. Below is additional information about engine oil: Purpose of engine oil: Both overfilling and underfilling engine oil can negatively impact the engine. Minor consequences include increased fuel consumption and louder engine noise, while severe cases may lead to engine oil burning. Engine oil is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. It is used for lubricating internal combustion engines, with its main functions being to reduce friction and wear on moving parts, as well as to remove sludge and varnish from the engine. Oil filling specifications for different models: The 1.4T engine (EA211 model) requires approximately 3.5 liters when completely drained. The 1.8T engine (EA888 model), which powers every generation of Audi A4 as its classic core, needs about 4.5 liters. The 2.0T engine shares the same EA888 model as the 1.8T but features different piston strokes. The 2.0T increases displacement by lengthening piston strokes and requires between 4.7 to 5 liters of engine oil.
I recently researched the oil capacity of the Audi A4 and found that it varies depending on the engine. The newer 2.0T engines require around 5.7 liters, such as those in the B9 generation models, while older versions like the 1.8T may only need 4.8 liters. The oil level must be precise—too little oil can lead to insufficient lubrication and accelerated engine wear, while too much can cause excessive oil pressure, potentially leading to leaks or seal damage. I recommend consulting the owner’s manual, as requirements differ by model year. It’s also advisable to use Audi-certified oil, such as VW 502 00, to ensure compatibility and protection. Regular oil changes are crucial, typically every 10,000 kilometers, as fresh oil helps extend engine life. When topping up the oil yourself, remember to check the dipstick when the engine is cold and keep the oil level in the middle range to avoid inaccuracies.
