Any updates/feed back on this?

My car seems more responsive since switching from Chevron 94 to Shell 91 Nitro+

Shouldn't Shell 91 be priced the same as Chevron 91?

Not if suckers such as ourselves are willing to pay for it! :lawl:

both vehicles are more responsive. I think it is due to the more stable fuel of 91 Nitro

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

Do you guys have any proof (ie: data logs) to back up these claims?

butt dyno bro

It's all the same shit.

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.

^^ 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%.

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.

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.

I have got a tuned MB E-Class with a V8 Engine.

Just filled up Shell 91+ Nitro with almost empty tank today.
My Engine ran quieter and smoother than Chevron 94.

For Performance, I didnt feel much differences.
Maybe I didn't run aggressive enough to see......

My car only needs 87 :okay:

That just means you need to go out to find a tuner and get yourself a custom tune so that you can max out your engine.

Shell charging more for premium gas than other stations is just plain stupid.

Chevron 87 is 10% ethanol.
94 is 0.
89 and 91 is somewhere in between as they mix 87 and 94 to get 89 and 91 I believe.

Please, elaborate. I am (and many others I'm sure) are dying to know! :hotbaby:

Damn... It is such a heresy for a company to charge premium prices for a superior product when they know such a demand exists... For the benefit of public good, they should have just sold it at the same prices as their 87 octane E10 gasoline... FailFish

Because the base gas is the same. If you thing adding some additives makes a big difference there's companies that are willing to sell you bottles full of stuff.




Shell Nitrogen Enriched Gasolines - Canada

When a person opens up his flap to get gas it's says something like Premium fuel only. So why would someone driving a 3 series BMW pay more for Nitro. People using an app like gas buddy would never got to a shell for premium fuel.


Shell Nitro just adds more cleaning agents that they claim will clean thing like your fuel injectors. Why not just just add a bottle of fuel injector cleaner ever 6 months or so?

You can hear the pump alternating when you get 89/91 at most places.

As a side note, I've never heard of anything that actually requires 89, only 87, 91 and 94. What on earth uses 89?

There's a few cars that recommend mid grade. 89 is just a mix of regular and premium. most modern pumps have a blending capability so have mid grade is a no brainier.

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.

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

Just from my personal experience... I got better fuel economy going from Chevron 94 to Shell 91. Stage 2 tune for 91 octane (US).

Butt dyno agrees as well.
