Can you use conventional antifreeze in an Audi?

While you can technically use conventional antifreeze in an Audi, it's not recommended. Audi vehicles typically require specific coolant formulations, such as G12 or G13, which contain certain additives to protect the engine and cooling system. Using the wrong type of antifreeze can lead to corrosion, reduced performance, and potential damage over time. Always check your owner's manual for the manufacturer's recommendations.
