Fuel Information
■Fuel requirement
Use of lower octane gasoline can cause occasional metallic knocking noise in the
engine and will result in decreased engine performance.
We recommend that you use a pump octane of 93 or higher to maximize the
performance of the engine.
Use of gasoline with a pump octane less than 91 can lead to engine damage.
■Top tier detergent gasoline
Because the level of detergency and additives in gasoline vary in the market, Acura
endorses the use of “TOP TIER Deterg ent Gasoline” where available to help
maintain the performance and reliability of your vehicle. TOP TIER Detergent
Gasoline meets a new gasoline standard join tly established by leading automotive
manufacturers to meet the need s of today’s advanced engines.
Qualifying gasoline retailers will, in most cases, identify their gasoline as having met
“TOP TIER Detergent Gasoline” standards at the retail location. This fuel is
guaranteed to contain the proper level of detergent additives and be free of metallic
additives. The proper level of detergent additives, and absence of harmful metallic
additives in gasoline, help avoid build-up of deposits in your engine and emission
control system.
For further important fuel-related information for your vehicle, or on information on
gasoline that does not contain MMT, visit Acura Owners at owners.acura.com . In
Canada, visit www.acura.ca for additional information on gasoline. For more
information on top tier gasoline, visit www.toptiergas.com.
■Fuel tank capacity: 15.6 US gal (59.0 liters)
Unleaded premium gasoline, pump octane number 91 or higher
1Fuel Information
NOTICE
We recommend quality ga soline containing
detergent additives that help prevent fuel system and
engine deposits. In addition, in order to maintain
good performance, fuel economy, and emissions
control, we strongly reco mmend the use of gasoline
that does NOT contain harmful manganese-based
fuel additives such as MMT, if such gasoline is
available.
Use of gasoline with these additives may adversely
affect performance, a nd cause the malfunction
indicator lamp on your inst rument panel to come on.
If this happens, contact an authorized Acura NSX
dealer for service.
Some gasoline today is ble nded with oxygenates such
as ethanol. Your vehicle is designed to operate on
oxygenated gasoline containing up to 15% ethanol
by volume. Do not use gaso line containing methanol.
If you notice any undesira ble operating symptoms, try
another service station or sw itch to another brand of
gasoline.

How to Refuel
Your fuel tank is not equipped with a fu el fill cap. You can insert the filler nozzle
directly into the filler neck. The tank seals itself again when you pull out the filler
nozzle. 1.Stop your vehicle with the service station
pump on the left side of the vehicle in the
rear.
2. Turn off the power system.
3. Press the fuel fill door release button.
u The fuel fill door opens.
4. Place the end of the filler nozzle on the
lower part of filler opening, then insert it
slowly and fully.
u Make sure that the end of the filler
nozzle goes down along with the filler
pipe.
u Keep the filler nozzle level.
u When the tank is full, the filler nozzle will
click off automatically.
u After filling, wait about five seconds
before removing the filler nozzle.
5. Shut the fuel fill door by hand.1How to Refuel
The fuel filler opening is designed to accept only
service station filler nozzles for refueling. Use of
smaller diameter tubes (e.g ., to siphon fuel for other
uses) or other non-service station devices can
damage the area in and around the filler opening.
The filler nozzle automatically stops to leave space in
the fuel tank so that fuel does not overflow as a result
of changes in air temperature.
If the fuel nozzle keeps turning off when the tank is not
full, there may be a problem with the pump’s fuel vapor
recovery system. Try filling at another pump. If this does not
fix the problem, consult an authorized Acura NSX dealer.
Do not continue to add fuel after the nozzle has
automatically stopped. Addi tional fuel can exceed
the full tank capacity.
If you have to refuel y our vehicle from a portable
container, use the funnel pr ovided with your vehicle.
2Refueling from a Portable Fuel Container P. 463
3WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured
when handling fuel.
•Turn the power sy stem off, and keep
heat, sparks, and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.

Fuel Economy and CO2 Emissions
Improving Fuel Economy and Reducing CO2
Emissions
Achieving fuel economy and reducing CO2 emissions is dependent on several
factors, including driving conditions, load weight, idling time, driving habits, and
vehicle condition. Depending on these and other factors, you may not achieve the
rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accord ance with the messages displayed on the
driver information interface.
• Use the recommended viscosity engine oil.
• Maintain the specified tire pressure.
• Do not load the vehicl e with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside
adds weight and increases wind resistance.
■Maintenance and Fuel Economy
1Improving Fuel Economy and Reducing CO2 Emissions
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test. For more

Turbo Engine Vehicle
Handling Precautions
The turbocharger is a high-precision device designed to obtain greater horsepower
by delivering a large volume of compressed air into the engine using a turbine driven
by the engine’s exhaust gas pressure.
• When the engine is cold just afte r starting, avoid hard or sudden
acceleration.
• Always replace the engine oil and engine oil filter according to the
Maintenance Minder
TM.
The turbine rotates at very high speeds over 100,000 rpm and its temperature
reaches over 1,292°F (700°C). It is lubricated and cooled by engine oil.
If you fail to replace the engine oil and filt er at the scheduled distance or interval,
deteriorated engine oil may cause failure su ch as sticking and abnormal noise of the
turbine bearing.
1 Turbo Engine Vehicle
The scheduled maintenance intervals for replacing
the engine oil and filt er is indicated on the
Maintenance Minder
TM. Follow the information of
when to replace them.
2 Maintenance Minder
TM P. 377
2 Recommended Engine Oil P. 388
The temperature gauge needle is at the mark
when you restart the engi ne after driving under high
load conditions such as at high speed or in hilly
terrain. This is normal. The gauge needle goes down
after you idle or drive the vehicle for about one
minute.

performing maintenance. Only you can decide whether you should perform a given
task.
• To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the 12-volt battery, all High Volt age system, and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood and hatch.
u Heat from the engine and exhaust can ignite them, causing a fire.
• To clean parts, use a co mmercially available degreas er or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the 12-volt
battery or compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if th ere is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on le vel ground, the parking brake is set, and
the power system is turned off.
• Be aware that hot parts can burn you.
