Sunoco station closing

[Hemi Chef]

The only Sunoco station closes today in Georgetown to my good fortune.
Earlier in the day they ran out of regular and now were selling
94 ultra 1.25.5/Litre.
Monica is sipping the good stuff this weekend!!

On the way home I heard gas was going up at midnight so my 80
dollar fill of ultra made me smile that much more.

[RFischer]

Great price when you can get it ... sorry to hear about your preferred food source drying up ...

[Hemi Chef]

Brampton is the closest now I believe,sunoco or shell in that order. I'll use the others in a pinch to get to sunoco.Never indie gas!!

[Zoban]

I'm typically stuck with Esso as that is where my gas card is for but I totally understand..

Weird to see a gass station close unless they're rebuilding.

Our tree hugging state government in Maine has decided that 93-94 octane pollute to much so they require 91 to be the highest octane sold. At least you can buy the good stuff. We can't buy diesel autos either, even if they pass every test in the world!

Ahh, well that sucks,now they are telling us what to drive and what not to drive...

Do you guys all have SRT's?

I personally only use the Sunoco 94 in my Firebird and it has 11.6:1 compression. My RT Hemi is only 9.6:1 and an SRT is 10:3:1.

I am sure most of you realise that higher octane fuel does not have more energy in it. It only has a higher resistance to knock, because it burns slower and colder. If you have a higher resistance to knock, you can run more compression and spark advance. Those 2 things have horse power in them. More compression only comes from changing to samllr chamber heads and or pistons. Spark advance can be changed with a tuner.

As a matter of interest, most of our higher octane fuels we can buy have more ethanol than regular and therefore has less potential energy in it. Ethanol has a lower calorific value than plain gasoline. So if you use premium in your car and it was designed and tuned for regular or midgrade, you likely get poorer mileage and possible build ups in the combustion chamber since the fuel is burning slower and colder than it was designed for.

My RT has the Flashpaq tune in it which advances the spark and therefore needs the 91, instead of the 89, but I would never put the 94 in it unless I was taking it to the track on a very very hot day as a percaution. BTW it would likely make a little extra hp with the 91, as long as the PCM did not see any knock and retard the spark.

My personal use of fuel:

-Firebird Sunoco 94
-Magnum Esso 91

Hopefully some of you find that interesting.

ah, but sunnoco 94 on a diablo tune for 93 works well. yes, 94 on a tune for less is actually a waste. since the engine isnt advancing the timing for it.

Cool!

I just wanted to make sure. I have met a lot of people who thought they could make more power just by adding higher octane fuel. I think the oil company adverts have a lot to do with that though.

My wifes car only uses 91 octane and came from the factory with 11.5:1 compression, the highest I have ever seen in a factory gasoline motor.

[Fargo59]

for sure. the Gen 1 3.5's (93-97) had a compression of 10.6:1 and still took 87 or 89. its all in tuning.

I will have to reread the pump, i recall the lower grades having the higher ethanol ratios,
15% 87 octane, 10% 89 octane 5% 91 octane 0% 94

Which would make sense since they are blended at the pump.

[Hemi Chef]

My 5.7 usually gets 89 as per instructed.Am I harming anything by running high test?
Chris care to chime in? Fnky you out there?What say ye gents.

From Sunoco's website:
Ultra 94
Get the Ultra 94 advantage
Driving is all about performance – and getting the maximum from your vehicle is what Ultra 94 is all about.
Developed with driving enthusiasts in mind, Ultra 94’s unique performance blend has made it the fuel of choice for both champions on the track and drivers on the street throughout Ontario.
Ontario’s only super premium gasoline
Ultra 94 has the highest octane of any gasoline available at retail stations in Ontario. Its high octane formula not only meets the CGSB (Canadian General Standards Board) performance requirements for super premium gasoline, it surpasses them.
Why is octane important? Octane is a gasoline’s ability to resist pre-ignition – that is its tendency to ignite before it’s supposed to in your engine. Choosing an octane lower than your vehicle or conditions warrant can result in improper combustion and reduced horsepower and acceleration. This is particularly true of cars with higher mileage, high performance vehicles, and many of today’s smaller, high compression engines.
Ultra 94’s higher octane ensures you always get the maximum horsepower, maximum acceleration and maximum performance from your vehicle, even under tough driving conditions.
Higher detergency for maximum year-round performance
Ultra 94’s higher detergency level significantly exceeds the “TOP TIER” performance criteria set by BMW, General Motors, Honda, Toyota, Audi and Volkswagen. Its advanced detergency level will actually clean up your car’s fuel injectors and intake valves, not just keep them clean. All vehicles can benefit from the higher detergency contained in Ultra 94. Cleaner engines help provide optimal fuel economy, reduced emissions and ensure your vehicle delivers maximum performance year-round.
Performance and an EcoLogoM
Up to 10% ethanol enhanced since 1996! Like our other Sunoco ethanol-enhanced gasolines, Ultra 94 sports Environment Canada’s EcoLogoM seal of approval. We’re proud to offer gasoline certified by EcoLogoM, Canada’s most widely recognized and respected environmental certification mark.
Higher performance. Cleaner engines.
No other gasoline available combines an EcoLogoM designation, detergency exceeding the TOP TIER standard and Ontario’s highest octane.
Get the Ultra 94 advantage, and maximize your vehicle’s performance!

You can easily see where Rampant was talking about the oil company advertising leading the consumer to believe they will get more power from higher octane gas.

Also clearly shows were their ULTRA94 has "up to 10% ethanol" and seeing that Suncor Energy (Parent company of Sunoco) has their own ethanol plant, you are getting the full 10% every time.

From Suncor's site:

Ethanol
To support our goal of providing consumers with high-quality products that have a lower environmental impact, Suncor operates the St. Clair Ethanol Plant in the Sarnia-Lambton region of Ontario. The ethanol produced at this world-class facility is blended into Sunoco gasoline (Sunoco retail stations in Ontario are owned by Suncor).
Ethanol offers numerous benefits:

• Ethanol production puts local people to work. Construction of the facility created about 250 jobs, while 46 full-time positions have been filled to operate the facility.
• Ethanol is a cleaner burning, renewable resource. It's a natural product and is biodegradable.
• Ethanol is a natural gas-line antifreeze in winter.

Expansion Underway Suncor is investing $120 million to expand the St. Clair Ethanol Plant and double the production output to 400 million litres per year. The expansion, which is expected to be complete in late 2009, is expected to:

• create approximately 250 jobs during construction
• expand the facility’s full-time workforce by about 20 positions, to a total of approximately 66 positions
• expand local economic base of community by increasing local and regional tax base
• boost demand for agriculture projects; the expanded facility would require about 40 million bushels of corn each year, about double what the facility utilizes today.

Hmm after reading the posted replies I think I am gonna go hug my ESSO card and be happy with the 89 that I am using..

Thanks all..

[Fargo59]

basically put, if your car isn't designed for it, or doesn't ping on its own, you don't need it. but a run through of it once in a while will help purge out "crappy" gas.
