how dangerous is it really? I mean I've run 89 octane with a good ratio of premix, I figured I'd be at 87 octane at best. Really though wouldn't you have to see something like 85 or below to really start risking something? On a NA setup. FI is entirely another story. I recall that being a popular tactic in the rotary circuit, hauling in low octane fuel.

Wow, thats strange, V-Power is 98 octane here in Australia:

 

Different standard for measuring octane. You guys use RON, right?

 

Thats correct... l'm guessing USA does not?

 

We use an average of RON and something else ... checking Wiki ... yeah, an average of RON and MON: http://en.wikipedia.org/wiki/Octane_rating

 

USA uses Research and Motor octane ratings, averaged.

Motor is usually 7 to 9 numbers lower, so 98 RON becomes USA 93/94 (very roughly).
94 is the highest I've seen around here......

Cheers guys, I shouldn't have been so lazy! I'll admit, it's just something l expected to be universal...

 

Ok...I squeeked out 170 miles on 10 gallons of Shell. Doesn't look like a bad tank of gas...just looks like bad gas. I had similar results about a year ago when I ran Speedway gas a couple times. If only Sunoco was closer to my house.

 

I used 6 tanks of the new formula shell gas. I always use shell v-power.

All 6 tanks my MPG went down ALOT. 3 tanks into it I installed my BHR coils. MPG was still low.

Switched to Chevron 93 and it went back to normal.


The old formula shell V-power got me the best MPG out of any gasoline regardless of octane or brand. The new formula sucks for gas mileage. At least in Houston, TX.

There is a shell right next to where I live and they are usually a few cents cheaper. So this sucks for me.

 

I can state for a fact the "new" Shell gas is mixed with 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, and trace amounts of other gases.

 

I drove 15 miles on the gas light (out of town) to find a non-shell station just to avoid the Nitrogen Enriched gas. Passed 2 of them and some arco, etc places to find a Mobil station.

 

Shell seems to be ok for me.

2 Tanks. my MPG has increased !

Before : I barely be able to make 160 b4 my light goes on.
After Shell : I can make it to 170 b4 my light goes on.

Today, I filled it up with BP's Invigorate . Lets see what will happen.

 

Update, on the new Shell Nitrogen Gas for me. I get better mileage when just normal driving, under 7K rpm on a whole tank.

If I am driving "spiritedly" I get less mileage than when I drive "spiritedly" on the old V-power shell gas. I wish I had a choice between old V-power and the new Nitrogen V-power.

I think I get a little more omph on the new Nitrogen V-power though, but it could just be me.

 

I drive admittedly like I stole my car, get 200miles on a tank, 250 miles if freeway driving. Spirited about 180, fill up with chevron or mobil. used to fill on shell when desperate until the whole nitrogen thing....

 

I just tried this out the other day by accident.. 1 gallon in 5 miles epic.. switched back to mobil very quickly.

 

jesh, I thought mine sucks. I bithc when I get to 220 for a 1/4 tank. usually light isnt until 260 or so.

89K miles on a 2004 LY.

 

^.................damn near impossible Shady.
Something is drastically wrong with the way you measured it!

 

shady: not possible to get 5mpg, not even in this car.

Been using it since it came out, haven't noticed any difference. Mileage is right about where it normally is

 

if I can get 220 till the light comes on. I will sell my Honda FIT right away.

 

ny: that's crazy that your mpg is so low! I'll go 240 before I get to the gas station and the light STILL isn't on.

 

So my engine has a problem ?

KEVIN WHERE ARE YOU ?!

 

I've been using only shell v-power in my car ever since I got it. I noticed no difference from the added nitrogen in the fuel.

 

I wonder what the longterm effects of adding N20 in fuel is to emissions, particularly NOX??

 

Um, the nitrogen is a scam.
All gas has nitrogen mixed in it.
Air is 78% nitrogen.

 

On a side note isn't it a bit odd that our shell nitrogen is ethanol free? I figured they would use ither one or the other ethanol or no ethanol. Also it seems like I'm getting way better mpg. Its thursday and I'm at half a tank-check previous posting for relavance. Ill reset my milage on the next fill for an official mpg.
