What kind of gas does a 2008 Acura take?
Most 2008 Acura models require premium unleaded gasoline with an octane rating of 91 or higher. Always verify the exact specification for your specific model by checking the owner's manual or the fuel-filler door sticker.
Model-specific fuel requirements
Here is a quick guide to common 2008 Acura models and their fuel recommendations.
- 2008 Acura TL: Premium unleaded gasoline with an octane rating of 91 or higher is recommended to maintain optimal performance. Regular gasoline is not recommended.
- 2008 Acura MDX: Premium unleaded gasoline (octane 91 or higher) is recommended; using lower-octane fuel can reduce performance and efficiency.
- 2008 Acura RDX: Premium unleaded gasoline (91+ octane) is recommended due to its turbocharged engine; regular gas is not advised.
- 2008 Acura TSX: Premium unleaded gasoline (91+ octane) is recommended to sustain optimal performance; regular gasoline is not recommended.
In short, premium gasoline is the norm for these 2008 Acura models, and using lower-octane fuel can impact performance and efficiency. Always confirm the exact requirement for your vehicle.
Why octane matters
Octane measures a fuel's resistance to knocking, which is premature detonation inside the engine. Higher-compression engines found in many Acura models require higher octane fuel to prevent knocking and to maintain performance and fuel economy.
Using a lower-octane fuel than recommended can cause knocking, reduced power, higher emissions, and potential long-term damage. Conversely, using higher-octane fuel than necessary typically does not provide extra benefits in engines not engineered for it, but it won’t harm the engine.
Locating the exact spec for your car
To be sure, locate the owner's manual section on fuel requirements or look at the fuel door sticker, which lists the recommended octane rating and whether premium is required or merely recommended.
Summary
The 2008 Acura lineup generally calls for premium unleaded gasoline with an octane rating of 91 or higher. Confirm the exact specification for your model and trim to ensure you meet the factory requirements.
