Am getting a new, never titled 04 NSX for $72k...is this a good deal? Also are there any known Problems with using 87 Octane gas?

Octane to Use-is 87 ok?

LOL. 91 only my friend. Although ecu can likely compensate via knock sensor for decreased performance...if you can afford a $72k car, you can afford premium gas I say.
Oh no, not this again! Next thing you know, we're going to have interpretations of the owners manual. Then people are going to paraphrase what the manual says. Then we're going to have a poll on what kind of gasoline we use... Argh!
haha, you should use Diesel Fuel :biggrin:
hopefully its not 87 with 10% ethanol,
ethanol sux =(

Not this question AGAIN 
Do what the owner's manual says. I agree with the above post, why pay $72k for a car but don't want to put 91 octane in the tank?

Sounds like a great deal, I bought an 02, when the 03's where knocking on the door and paid 74k (with the only options which are now standard). IMHO, think that you saved 17k from the "list price", now you can afford to ante up the extra .10 per gallon for premium fuel, and get the performance out of the car that you wanted when you decided to buy the car.

theres another post with a guy that sold his 04 for 63k..go figure..

Try the 87, then try the 91, and then try the 91 nonoxy. Then decide. the car does not care. I use nonoxy for max power and mileage even though it's only rare that I get on it.

Please tell us your Vin # for the records and let us know how strong the NSX engine is against knock. :wink:
Sorry, guess I wasn't clear. I use the 91 nonoxy. But I do believe the Honda engineers put in knock sensors that work.

That maybe true but the retard can only go so far. Why not rev to 8000rpm a bunch of times in winter climates and see how well the engine hold up with a wideband?
To be fair, you could run 87 octane with no problem, as long as the tach stayed below - say - 4-5000 RPM. The higher octane provides no extra fuel efficiency in itself; it keeps the fuel from detonating too early. When you start pushing the engine faster and faster, you need a higher octane fuel to run without predetonation.
If we had engines that ran at 12,000RPM, we'd all need Jet-A unleaded at 106 (?) octane.
Of course, I'm not sure what the point of having an NSX is if you don't take it up past 4k RPM - you're really not even in the effective powerband yet. But my point is, you could run the low octane without damage to the engine.

I think you've mistaken the NSX for the Fiero, another mid-engine car.

lol do you people ever sleep ?
I say 87 oct on a performance car is just silly. :wink:
get a civic. :tongue: VROOOOM VROOOOOOOOOM VROOOOOOOOOOOOOOOOOOOOOM! :biggrin:

when i get my nsx, ill hook up the Apex AFC-II from my supra to the NSX and see how many knocks the car gives me with 87 :biggrin:
ill have a 5 gallon jug of 91 for back up and 2 gallon of 87 in the tank :biggrin:

The Prelude H22a had a knock sensor that pulls timing if you put in 87 octane, it was a feature it's even covered in the owner's manual. Given the 2 cars came out at the same time with similar VTEC systems, they likely both do it. Although I would say it's a worse idea to do it on the C30A/C32B

just a quick question about this what about sport bikes then, that are insanely high reving?
Here is a dyno showing power loss due to 89 vs 91 octane.
The dyno isn't of a NSX, but you get the idea.

This is the type of information I can use. The HP drop however, is two different cars. Are they the same with the same fuel?

Looking at the data on the picture.. it looks like its the same type of car (VW GTI-VR6)but your right its not the same exact car.
I believe the data is taken with one car with 91 octane and the other with 89.

To answer the original poster, yes you can use 87 octane. However, you will be getting diminished performance (both in terms of power and fuel efficiency). Hardly worth the 10-20 cents per gallon you'll save.
Don't do it.
As I recall, one of the major trade rag's (I think it was C&D) did a pretty in depth comparison of several recent model cars where they dyno'd the cars using reg. unleaded and super unleaded and found that while the knock sensors did work (and thus prevent damages), the higher octane did, in most cases, make more power. A lot more power in some cases.
The moral... you're lucky enough to be purchasing one of the finest sports cars ever made. Do yourself and your car a favor and don't skimp on things like good gas, good maintenance and good tires.
My twelve cents.
