shell 91 nitro just got introduced here in kamloops. Anyone know how it is? I've Been a chevron fanboy. Both my wrx and tundra are tuned to 94 octane. But this new 91 nitro has a 99 Ron rating whereas chevron 94 only has a 98 Ron rating. Would love some info if someone is informed as I am pretty clueless when it comes to the complexities of fuel

[belaud]

It all comes out of the same refinery with different additives, the difference you'll see would be minute.

From what I see, the main selling point of Nitro is engine cleaning, not an increase in octane or performance, best stick with the 94 if that is what you're tuned for.

from that thread if anyone is interested.

This is kind of an interesting read. Its off of the Petro site. Maybe 91 with ethanol will offer more knock resistance.



Why is ethanol an effective octane booster?

The octane number written on the gas pump is Anti-Knock Index (AKI). It’s an average of two octane ratings using the same test equipment but using different operating conditions. The methods produce a Research Octane number (RON) and a Motor Octane Number (MON). Both were once considered important and that’s why AKI is an average of the two. With modern engines and fuels systems, recent studies have shown that RON is more important than MON. So in these cars, the higher the RON the better these cars perform. For an AKI rating of 91 the lower the MON the higher the RON. This difference is called sensitivity. All gasoline components have different sensitivity. Most hydrocarbon components have low sensitivity. Ethanol has high sensitivity and so, modern performance cars benefit from gasolines with ethanol. Why does ethanol have higher sensitivity? One reason is related to the cooler combustion that results from ethanol combustion. Higher knock tendency is directly related to higher combustion temperature.
Here is a comparison of two fuels with different octane with and without ethanol.

91 Grade - no ethanol
RON 97.2
MON 85.6

Ultra 94 - with ethanol
RON 101.5
MON 88

Notice the difference in RON number from 91 grade without ethanol (97.2) and the RON of Ultra 94 (101.5). The difference is 4.3 numbers. That is significantly more than the 3 numbers difference between 94 and 91 AKI labelled on the pump. That is why gasoline with ethanol can be the best performance fuel for today's cars.


looks like RON is the better number to go by for modern vehicles not the AKI octane rating on the pump, which would mean you should get better performance from Shell 91 than Chevron 94, which is also cheaper as well.

VIDEO BASED ON RON OCTANE, not AKI(north american) OCTANE

https://www.youtube.com/watch?v=dDHwCWdrtdg

So based on the research Chevron 94(98RON) has less performance results than Shell 91(99RON). it boils down to if you like Techron or Nitrogen additives, as performance goes to Shell 91 Nitro+



I think ill switch the WRX and tundra over to Shell Nitro+, easy and free for me :)

[boibuddha]

Don't think Shell 91 nitro+ is cheaper than Chevron 94. I filled up two days ago and there was $0.19 bump compared to regular gas, $1.339 vs $1.529.

If I remember correctly, isn't Chevron 94 about $0.14 more than regular?

you are correct. they are the same price in kamloops right now actually. 129.9/L for both

If your car is not tuned for 94 stick with 91 if your car requires premium.

I can't watch the video atm, but how do they compare in terms of real world knock prevention in a boosted vehicle?

[Tegra_Devil]

I can't watch the video atm, but how do they compare in terms of real world knock prevention in a boosted vehicle?

they mostly tested on how ROM octane levels improve performance in cars without a tune and vehicles automatically adjusting to the fuel.

it shows that a base model joe blow car wont see any improvement. but cars in the level of a GTI and STI get performance improvements.

So basically, if your looking for performance on a semi-sportscar or full sportscar, you will get better results based on ROM levels compared to (north american AKI octane levels)

But to answer your question, the higher the RON rating the less likely you are to pre-ignite or detonate (remember fuels in north america use the AKI rating, so an 89 AKI octane could have a higher RON rating than a 94 AKI octane, because AKI averages out your RON and MON. you could have a high MON and low RON which will show you a high AKI octane, or a fuel could have a high RON and low MON, which would be the better fuel to choose as you always want the higher RON. RON maxes out at 100 for conventional automotive fuel(not included is race fuel)


If your car is not tuned for 94 stick with 91 if your car requires premium.

the wrx is currently being fine tuned for chev 94 octane through Clark Turner tuning on my Cobb AP, ive been data logging for him and he has been tweaking. But he has been saying today that we should try Shell 91 because of the RON rating and see if we can squeeze a tiny, tiny bit more out.

The tundra auto tunes via the BullyDog tuner based on what fuel is in the system

[reza]

I'm getting confused here with contradicting theories.
the MON number you want to be higher, not RON.
RON is done at idle(600rpm) while MON is done under load with higher rpm (900rpm)

Research Octane Number (RON)
The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane.

Motor Octane Number (MON)
Another type of octane rating, called Motor Octane Number (MON), is determined at 900 rpm engine speed instead of the 600 rpm for RON.[1] MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern pump gasoline will be about 8 to 12 octane lower than the RON, but there is no direct link between RON and MON. Pump gasoline specifications typically require both a minimum RON and a minimum MON.

but then you have petro-can here saying RON is more important:

somebody wanna clear it up?

from my experience running 22psi in order of most resistant to knock:
1.92 chevron from the US
2.91 shell here
3.94 chevron here

[Timpo]

ok I've used both and I saw absolutely no fucking difference.

Realistically, you probably need a dyno to see the difference. Just stick to Chevron, presumably they're better gas.

[R. Mutt]

The difference will be negligible but I've always found shell 91 to be more stable under high load. The knock threshold isn't higher but more consistent where as chevron was less stable under high load. Neither Shell nor Chevron contain ethanol. If you want better performance but are knock limited you should look to spray meth or switch to e85....the latter probably unrealistic because of your location. If it were me I would go with Shell.

[Liquid_o2]

Have been wondering the exact same things over the past few weeks. Always was a Chevron guy with all my previous cars, but started using Shell 91 (no ethanol) once I got my Civic Si. Noticed recently that Chevron 94 (also no ethanol) is a few cents cheaper than Shell, but the car is tuned for 91 according to the manual.

[Hot Karl]

i always fill up in the states. but when i'm home i use shell because chevron 91 or 94 performs worse then us 92. and shell performs like us 92.

my car has some lag/turbo delay on chevron. a-ok on shell and us 92. i've tried big name us stations and generic ones. no issues there. and it's been 2 years of 95% of all fills in us.

for reference i drive a 01 golf 1.8t with a chip and downpipe.

[underscore]

On a side note then, how does Shell 89 compare to everyone else's 91?

[whiteTDIpowa]

I would never get my car tuned for 94 octane in Canada....cause its not 94, stick tuning your car on a 91.

[Jmac]

I've exclusively used Chevron pretty much my whole life, but this thread has convinced me to give Shell a chance.

[46_valentinor]

shell 91 is the only one without ethanol too unless you're willing to fork out extra for chevron's 94.

[meme405]

Tuners at MNR told me put in Shell 91 when I took it in for a tune.

They said it is the most reliable gas available here, and also performs the best for my particular car (NA V6).

Keep in mind guys, that octane is actually a retardant, it stabilizes the combustion, but it also slows it down, and lessens the explosion. Therefore higher octane fuel is actually less powerful fuel volume for volume.

I was tuning for 94 and my max power I could achieve was 348WHP on a mustang dyno. Went across the street to fill Shell 92 in a jerry, and without doing any sort of adjustments, the car made 372 WHP the very next pull.

[R. Mutt]

Nice...your ecu's IAM liked the US Shell

[whiteTDIpowa]

Shell 91 and chevron 94 are priced exactly the same....I think it's safe to say chevron is over compensating their octane rating.

[und3f3at3d]

Are they the same? Just filled up on shell 91, $0.20 more than regular. Anyone can confirm on chevron?

Lol I think I only use chevron because of advertising and marketing, and its easily more covenient. In Richmond, there is only 1 shell on garden city and lansdowne, but easily almost 10 chevrons

not at all. Shell 91 is miles ahead of chevron 91 in regards to RON octane level and stability.

so its not hard to understand why chevron 91 is less money....because it is that much shittier than nitro 91

I went to an almost empty take of Chevron 94 before filling up with Shell 91 on my 07 CBR 600RR.
Bike has a Titanium header back exhaust and a power commander 3 and a 520 chain and sprockets.

With the tank of Shell 91, I don't feel any difference but more importantly, I only got 180 km's out of my tank of gas.
This was all city stop and go DD.

I'll give it a few more tanks before I try plotting the data on a graph.

[Traum]

^^ With most Shell stations not using dedicated pumps for the V-Power gas anymore, I wonder how much of your tank of gas (on the bike) is really the 91 octane stuff. There has to be at least a litre's worth of gas in the visible section of the gas hose alone... With an 18L tank, 1L's worth of regular gass is equivalent to ~5%.

[Amuse]

I just did a price comparison today of gas in Vancouver:

Shell:
87: $1.379/L (up to 10% ethanol)
89: $1.499/L (up to 5% ethanol)
91: $1.579/L (no ethanol)

Esso:
87: $1.379/L
89: $1.479/L
91: $1.539/L

Chevron:
87: $1.379/L
89: $1.469/L
91: $1.519/L
94: $1.549/L


Anyone know the updated ethanol content in Chevron Canada gas?

So basically, cars requiring premium fuel can fill up Chevron 91, which is $0.06/L cheaper than Shell's 91 premium fuel. But Shells' 91 is comparable (and a bit better?) to Chevron 94.

[bcrdukes]

But Shells' 91 is comparable (and a bit better?) to Chevron 94.

I think when it comes down to actual dyno results from RS members on the forum (tech forums especially) the evidence is clear that Shell 91 does yield better results using Shell 91 over Chevron 94.

I do recall running Chevron 94 on a few of my cars and it ping'ed like crazy. I believe R.Mutt has a comprehensive thread on his fuel / dyno experience in one of the tech forums.

IMO, there are 3 types of people that drive cars requiring premium gas:

1) car requires premium, but they fill up with regular anyway
2) they fill up with premium b/c the gas flap sticker says so
3) they fill up wiht premium because they know they need the extra knock resistance

The majority of us in this thread probably belong to category #3. But for those consumers that belong to Category #2, I am 100% willing to bet that there are enough of them that don't bother comparing the price of premium gas between different brands. This doesn't mean they don't check / compare gas prices, but since our gas stations almost exclusively only publish the price of regular (and sometimes diesel) on site, that is the number they look at.

As long as there are enough of these drivers to keep filling up with Shell 91, that is really all Shell cares about.

[Manic!]

Just hope Shell did a lot of testing this time. Because 2002 they changed there formula the messed up a lot of cars.

Because it's not needed. All gas sold in Canada meets or exceeds manufactures requirements. If other gas was bad for your car and was clogging up injectors the company selling it would be sued. It's mostly just marketing. When Shell changed the name to V power people thought it was a new gas as one RS member put it "chocked full of detergents" but it was the same gas as before. They just changed the name because all the other countries where using the V power name.

On the other hand, we do not have anyone reporting that they are able to produce less knock and higher hp with Chevron 94 compared to Shell 91 yet.

I would not take it as a universal truth that Shell 91 is "better" than Chevron 94. But there is certainly circumstantial evidence to suggest it is.

Almost all regular gasoline now has some ethanol in it. Our Esso branded gasoline ethanol level never exceeds 10%. Gasoline with 10% ethanol content is known as E10, and with 15% ethanol it’s known as E15. Ethanol flex fuel (formerly known as E85) has between 51% and 83% ethanol, with the remainder being gasoline. All gasoline vehicles can use E10. E15 is only appropriate for use in flex fuel vehicles or a very small percentage of the newest vehicles. Anything higher than E15 ethanol content is only appropriate in flex fuel vehicles.

anyone here who data logs.. wanna do a test? i'll paypal you $2.50 (but you gotta eat the 3%) towards your tank of gas

[bcrdukes]

You fucking troll shit...

[bcrdukes]

Thank goodness I ride a bike. None of this polluting nonsense of ethanol and ethics. :rolleyes:

[Manic!]

Why does it not count when you clearly stated "it's all the same shit?"

Because the base gas all comes from the same refinery.


Something funny

Years ago Ferrari recommended Shell Helix oil at 80 bux a litre. Now they recommend Quaker State that costs 5 bux litre at Walmart. Both made by the same company.

Going from Chevron 91 to Shell 91 just last week, seems like my car runs smoother, more powerful, and better fuel economy.

[Akinari]

Are we really having a conversation in here that Shell 91 makes a car go faster than Chevron 91?

Might as well start the conversation on how MOTUL makes a car go faster than Mobil 1.

:fulloffuck:

People need to stop making shit up.

people need to stop ignoring hard numbers. i like how you haters just discount the rom rating. which is higher at shell.

dismissing anecdotal evidence from EVERYONE just makes you seem like a jerk.

honestly do you have a boosted car? something that needs premium?

in my experience cars with boost, heavy mods etc that need premium, NEED FUCKING PREMIUM. there's this thing called ping and detonation that happens.

my car runs better on shell or us92 then on chevron94. it's an immediate and obvious difference and anyone can tell the difference.

how about those shops saying US tuned cars where running worse on chevron 94 then us92?

we understand you watched an episode of mythbusters and know everything about cars now. but maybe some actual enthusiasts that are up to date in the scene might, just might have more experience in this field then you.

Please turbo your car Akinari.

Hater? Why the hell am I a hater now? What was I even hating on? :pokerface:

I was not talking about US Shell 92 versus Canadian Chevron 94, the latter of which I am aware performs worse. I am also aware that boosted cars are sometimes significantly more sensitive towards the type of gas used. If you notice what I wrote in my post, I was solely comparing Shell and Chevron 91 in Canada. My post was in response to the previous post which was made by an N/A S2000 driver who claims his car "seems to feel more powerful" after putting in Shell 91 over Chevron 91.

Seems to be placebo to me.

TLDR....Race War's is coming up,what is Faster again?

RS gas challenge 2015!!!

Drive your car till it is empty.
Have 2 Jerry cans one with Shell the other with Chevron.
Have someone pour some gas in your car without telling you.
Do this 5 times.
Each time guess what type of gas is in your car.

Who thinks they can get all five right?

[underscore]

If your butt dyno can feel the difference, your motor is already fucked by the shittier one. Anything other than dyno plots with AFR's or knock isn't much use here.

[smoothie.]

where the arco at?

[Geoc]

I swear by Domo gas, it's the best. I avoid other gas stations when I can and fill up at Domo only.

[IMASA]

Some of you guys that are "tuned on 94" should make the trip out to Arcade station and try some E85. You can probably run a 15% E85 mix without having to adjust your tune. Also, Arcade now carries Shell 91 Nitro.

Mix ??
I have around 40L of Shell 91 Nitro+ in the tank.
So, I just go to Arcade pumped in another 6L of E85 ?

Both Gasoline will be mixed in the tank evenly ??

[Amuse]

I noticed after filling up 91 Shell with Nitro, it has better gas mileage and more powerful BUT when i start my engine right in the morning or after the car has sat for like 8 hours, it's pretty loud. It quiets back to normal after warming up. Also, my engine oil suddenly became more dark.
Not sure if this is related to the sudden change to Shell 91.

I'm going back to Chevron 91 to see if it goes back to normal.

I thought people where buying 91 because it had no ethanol but your saying people should add ethanol? :fulloffuck:

that's what amir keeps telling me but west van is so far :okay:

[Acethriller]

Ran shell nitro a few weeks ago, and cold starts were very rough, car would barely start, thought something was wrong with my car. Filled up with Chevron after and problem disappeared. Fast forward to recently, filled with shell for the second time (different station) and the rough cold start issue is back. Anyone else experiencing this?

[LP700-4]

Not sure if srs. Domo gas = petro canada gas

[SumAznGuy]

Just out of curiosity, how bad is PC gas?
And for that matter, how good/bad is Esso gas?

where can you get shell 92 in lower mainland?

i've only seen 91, and my car felt slower than chevron 94.

Your car probably feels slower now because of the heat?
