The 2016 Audi Q5 runs on premium unleaded gasoline with an octane rating of 91 or higher.
Fuel type and octane requirements
In general, all gasoline-powered Q5 models require premium fuel rather than the standard 87-octane. The octane specification is tied to the engine's turbocharging and knock-suppression needs; higher octane helps prevent knocking and maximizes performance and efficiency. Always consult the owner's manual for the exact requirement for your VIN and market.
Gasoline engines
Premium unleaded gasoline with a minimum octane rating of 91 is recommended. In many regions, 93 octane provides the best balance of performance and smoothness, especially in warm weather or when the engine is under load.
Diesel variant
Some markets offered a diesel version (3.0L TDI) that runs on diesel fuel. This variant is not compatible with gasoline, so do not refuel a diesel Q5 with gasoline.
Market variations and practical notes
Octane labeling varies by country. In the United States, premium gasoline commonly means at least 91 octane (AKI). In Europe and other markets, octane is often listed as RON (for example, 95 or higher). Check the fuel filler label and your owner's manual for the precise specification for your vehicle. If you’re unsure, use premium unleaded gasoline and avoid regular 87 octane.
Summary
Bottom line: The 2016 Audi Q5 typically requires premium unleaded gasoline with an octane rating of 91 or higher, depending on the engine and market. For diesel-equipped models, use diesel. Always verify the exact specification in the owner’s manual and fuel door label for your vehicle.
