i am about to do an oil change on my 91 nsx and was wondering if anyone has any experience using 0w 30 mobile one? or should i continue with the 5w 30. just curious thanks guys.

anyone use 0w 30 synthetic oil
- Thread starter Kelly's NSX
- Start date
In your area, you won't see any difference in the two
"w" means the oil viscosity in "Winter" conditions (ie: cold weather) 
Both are still 30 weight otherwise.
0w30 ---> Civic hybrid
10w30 --> NSX
10w30 --> NSX
In Florida, or wherever the climate is warm throughout the entire year, there really is no difference using 0W-30 or 10W-30...
The Civic's use 0W30, 5W20 or other lower weight viscosity for better gas mileage. That 1, 2, 3 mpg makes a difference.
With today's high quality syntehtics, that don't shear if replaced at hte right intervals, and the right conditions, there isn't an loss in going to 0W, or 5Wx.
I've done oil analysis and it has confirmed that. The biggest reason that Honda recommends 10W-30 is because with non-synthetic, after 7500 miles that oil may veyr well have sheared to 0W-20!
.. If you want to determine the "best" oil to use for your application, do a oil sample. Blackstone is $20.00. Go do it.
Or you can just follow the factory specifications and call it a day. Why even consider going to a weight like that, unless you got a killer deal on it?

Found this on another site:
just remember guys when buying synthetics check the back of the bottle. an oil with the a High Temperature High Shear # greater than 3.5 is considered an A3 oil.
ACEA A1/B1 Oil intended for use in gasoline and car + light van diesel engines specifically designed to be capable of using low friction low viscosity oils with a High temperature / High shear rate viscosity of 2.6 to 3.5 mPa.s. These oils may be unsuitable for use in some engines. Consult owner manual or handbook if in doubt.
ACEA A3/B3 Stable, stay-in-grade oil intended for use in high performance gasoline and car + light van diesel engines and/or for extended drain intervals where specified by the engine manufacturer, and/or for year-round use of low viscosity oils, and/or for severe operating conditions as defined by the engine manufacturer.
ACEA A3 oils (good):
Amsoil 3000
5w30
Amsoil European Formula
5w40
BMW HP Synthetic:
5w-30,
Castrol Syntec:
0w-30
15w-50
Mobil 1:
0w-40
Motul 8100
5w40
Motul 6100
15w50
10w40
Royal Purple
5w40
ACEA A1 oils (okay, but not up to the task):
Castrol Syntec:
5w-30
10w-30
Mobil1:
0w-30
5w-30
10w-30

Castrol 0W30 or Mobil 0W40.
The factory recommends 10W/30. That's good enough for me.
Eneos 0W-50 here. Made by Nippon Oil and Eneos is also used in Honda F1 cars
