Canadian Tire gasoline

[HighFlyer]

I've been hesitant to fill up with them in the past since I'm not sure where they get their supply from. I just got a few CT gift cards that I can use for gas since I don't shop at their stores. Has anyone filled up at CT recently that could comment on the fuel quality?

[RBK]

Esso gas.

[DJ_Peanuts22]

go petro canada instead

[mannyb]

I use CAD Tire gas periodically with never any problems.

[FastFokker]

I've never officially measured, but I noticed it seems like I get less mileage out of a tank of Crap Tire gasoline.

By the way, my understanding is that Crap Tire Gas bars are not part of the Crap Tire store.. they're independently owned and operated.

[TrevorK]

Differences like this are usually in your head - there are only a handful of refineries that produce the gas. You may get a bad tank here or there (From any station), but it's highly unlikely to always get consistently bad gas these days from a gas station (In the past yes).

[FastFokker]

Yeah I've wondered if it was in my head.. but I really did compare the apparent mileage, and it seemed like I would go less far on a tank of CT Gas.

I do subscribe to the placebo effect.. but for some reason this seemed to go against what I had previously thought, that all gas was pretty much equal.

I don't know how to explain it, but I throw it out there for other CT Gas buyers to measure.. perhaps I'm completely wrong and it's entirely in my head. But it wasn't an isolated event.

[gilboman]

you only get Esso, Shell gas at the smaller chains/independents i think.

so it really doesnt make much difference.

[mlc2000]

Buy a diesel car and you'll never ever worry about mileage again,
unless you start getting the kind of mileage u get with a gasoline car.
Then you'll hang yourself. :cheesygri

[itsmypostoffice]

it's funny that you should bring up CT's gasoline. a few years back i saved a few cents at the CT station just before the yorkdale. nothing wrong during the first 2-3 fill ups but soon my car felt sluggish and the exhaust smoked. strong *gasoline* smell filled the cabin while idling at the traffic lights so i tossed my coupons and went to sunoco for a tank of their premium grade to clean out my injectors.

voila, no more problems. nowadays i use esso, sunoco, petrocan...the usual suspects. i realize they all receive gasoline from the same refinery but their renovated stations have new reservoirs and efficient pumps.

CT? i like their coupons but their gasoline has always posed problems for my car.

[FastFokker]

Yeah I always *WANT* to buy gas at Crap Tire, because I get money back that I can use.. but it also seems to affect my car. I swear it's not in my head.

I do realize there are only so many refineries and that the quality of gas is under pretty tight quality control.. so I can't explain it, but I have given up purchasing gas at Crap Tire Gas Bars, against my better wishes. :(

[myapple]

I don't know how to explain it, but I throw it out there for other CT Gas buyers to measure.. perhaps I'm completely wrong and it's entirely in my head. But it wasn't an isolated event.
in the past...i tried CT gas cuz they had bonus CT dollars and it was about 2-3 cents cheaper than all the other places in my area. For two fill ups, I consistently got around 100-150km less per tank with CT gas. assuming driving habits and outside temperatures were pretty constant...I would say CT gas sucks. mileage went back up after filling most of the tank with sunoco.

Honestly, if you feel your car performs better on Petro Canada gas - I say go for it. Whether it actually does or not doesn't matter, because you'll feel better about it.

It's just like people who buy home theatre speakers - buy what sounds good to you, not what the magazine says, because you listen to them.

[FastFokker]

Honestly, if you feel your car performs better on Petro Canada gas - I say go for it. Whether it actually does or not doesn't matter, because you'll feel better about it.It's not that other gas performs better, it's just that i noticed I didn't seem to get as good mileage on CT Gasoline.. and I tried it for quite a while as I loved getting the CT$$$.

I swear it's not just in my head though.. I pretty realistic and I'm trained in engines, so I understand gas is gas... I can't put my finger on it, and I didn't test it with enough detail, but the CT Gas I was getting just didn't perform up to the standard I was used to.

I don't believe in one gas being better than another, unless theres obvious intentional dilution of the gasoline.. and I understand there are a lot of filters and testing in place to verify the quality.. so I don't know. But it did seem to not hold up in mileage as well as gasoline from other locations.

So I'm not trying to dissaude people from purchasing CT Gas, but I would be interested to hear if a few people did their own mileage tests to see if there was any kind of validity to my belief.

I was the other way around. Sunoco gave me worse mileage than CT.

Why not get someone else to fill your tank for you but not tell you what gas station it was from. Then see if you can tell what kind of gas was put in.

[FastFokker]

Because I don't trust others driving my vehicle.

If I cared enough, I would just do a real test and keep track of the mileage, but now days my driving varies too much to make a valid test. I drive less these days and when I do, is almost always short trips, which completely throws off the ability to compare mileage calculations.

[wing0]

well, been filling the EL with CT gas since we had it.
gas mileage is still good, at least 600km per tank of gas.
I really think it's just our head playing with us.

[FastFokker]

If you've been filling the car with CT Gas since you owned it, what are you comparing against?

[wing0]

If you've been filling the car with CT Gas since you owned it, what are you comparing against?

well once in a while, I do fill it up with Shell or Sunoco if the price is better, but I never notice a gain or a loss just by switching.
sorry if i wasn't being clear.

[xien0n]

I was the other way around. Sunoco gave me worse mileage than CT.

Agreed. Maybe it's the ethanol they put in. There's less energy in the same volume of ethanol vs gasoline.

[KrispyFive]

CT gas is crap. I find that my car doesn't run all that great with CT gas. The last time I went to a CT gas bar was at my cottage in 2003.

On the way back home, my car ended up stalling on the 401. It just cut out, luckily I was able to pull over. Then after a couple of minutes I was able to get it started again and went on my way. A few minutes later it stalled again and wouldn't start up. I called CAA so that I could get it towed. It was a very busy night for them I guess since I was on hold for 10 minutes, I was trying to start the car every now and then and it finally started so I was able to drive home. The car drove like crap the whole way home. I took it into the shop and they couldn't find anything wrong with it, it was suggested that it was the gas. I then filled up with some Ultra 94 from Sunoco and it was much better.

I'd only buy from CT if there was no other gas station around and I was in desperate need of gas.

[weilyan]

I'm from Montreal and i'm doing a little experiment at this time

I have a 94 Integra RS, and filled it with Petro Canada gas and got roughly about 425 kms with a full tank. Last friday, i filled it up with the same grade(high octane....91 i think) of CT gas and am gonna see how much kms i can get from 1 full tank.

I live near the highway so between home and work there is a total of 5 lights (2 lights near home then highway then 3 lights off the Cavendish exit) and from home to school i have 2 lights and 5 stops signs.

I drive at an average of 120 kms on the highway and always keep the RPM between 2000 and 3000 (usually shifting up at 2500 unless i was going considerably uphill, i would shift up at 3000)

By the end of this week, i'll post an update on how much kms i get from CT gas.


P.S. a former work college of mine also has a 94 Integra RS and uses ethanol (at a gas station near Villa Maria metro...dunno which one though), he saids that even though it's about 2-3 cents per liter more expensive, he gets about 20% more mileage. Has anyone ever tried it?

[FastFokker]

You should ask the CT Gas Bar and the Petro who supplies their gas, for all you know it could be the same place. :D

Definitely sounds like an interesting test, though!

[Bullseye]

'nowadays i use esso, sunoco, petrocan...the usual suspects.'

CT buys all their gas from Esso, so if you fill up at Esso, you may as well fill up at CT.

[sunnybono]

I was the other way around. Sunoco gave me worse mileage than CT.

I've too noticed poor gas mileage on my 2004 Mazda 3 GT sport when filling up at sunoco :mad: . SOmeone told me that it has to do with the ethanol content in their gas. So now I buy from Petro Canada. :)

At Sunoco ===> 300kms/45L = 6.67kms/L of gas
At Petro ===> 460kms/45L = 10.22kms/L of gas

sk :)

[Bullseye]

I've actually done a fair bit of research on ethanol in gas, the conclusion seems to be that 10% ethanol in gas (as Sunoco has) will only have a very small effect on your gas mileage, if it has any effect at all.

In Ontario, they are passing a law that all gas sold in the province will require ethanol soon, so it's a moot point in any event. I forget the percentage, but I think it's 5% or 10%.

[gasnparts]

Canadian Tire uses ESSO
Zehrs Superstore uses ESSO
Most unbranded use whatever they can get their hands on at a decent price
Any independant that uses esso fuel doesn't get the additives that an esso site would get.

[nx2k]

i have a problem with people saying they get less gas mileage out of a certain station's gas.
how are you guys measuring, they only efficient way to measure is to run it from the absolute top to the point where it is about to spill out until it is bone dry and the car completely stops.
becuz u'd have to consider the fact that gas price is almost never the same as the last time you filled up to measure it or you didn't put the exact same amount in the last time you tried to measure.
if you are going by how many L to make 100km, altho your gauge will give you a pretty accurate reading on 100km altho it can still differ depending on your tires, you have no real claim that you indeed used X amount of litres to reach that mark.
you guys can be right or wrong about quality of fuel giving you better gas mileage but you really have to back up your claim as to how you are measuring it. I dont' remember a time where i put in the exact amount of litres and then used that amount to make so many km's cuz i wouldn't know how many litres i actually used
even digital gauges may not be accurate as the car is constantly moving around and may not necessarily get an accurate reading

I've noticed that as well on my 535i...I think I'm going back to Petro.

Right on the money. I was going to say the same thing... Cdn Tire gas is Esso gas with a different additives package. Also on another note, gas prices aren't set by stations as most people might think, and they aren't even set by the company of gas station you're at. They are actually set for all stations in a given area by some weird central office that tells each station what to set it's price to every morning. It is really strange/conspiracy like, lol...

(I once worked at an Esso station--anyone that's worked at a gas station would probably know this stuff. Like in the morning you have to call in what your price is and then they tell you what every gas station's price in the area is and what you have to set your price at. And then you write it all in this book... Strange stuff, lol.)

2 blocks from my house, at keele and bloor in toronto, there is a petro canada thats usually at the mid 90's per liter for regular.

5-10 blocks directly north on keele, just past dundas west, there is a canadian tire station that is usually a good 5-10 cents cheeper. 2 blocks north of that station, there is an esso station. they're usually about 2 cents higher then the CT station.

I'm calling shens.

[jason9945]

Wow,
this is an interesting thread.
I've run pretty much nothing but canadian tire gas in my (very old) car since I got it this summer! Wow!

I dont notice a difference between crappy tire and anywhere else, and I love the canadian tire money!

What does that mean? (I'm calling shens?)

And what does what you said have to do with what I said? I just stated how the prices were set and then you started stating stuff about prices being different. Of course the prices are different, I never said anything about them not being different. In fact that is what the central office is all about, the price difference between the stations is what they are essentially controlling--the difference in price between certain stations is usually kept the same regardless of the actual price. E.g. A Petro Canada on one corner might have a price of 86.9 and then an Esso on another nearby corner 87.9. The next day the price of that Petro is 91.7, the Esso price will usually be the same difference (-1 cent) so it will be 90.7. It seems they change things up a lot more in larger cities than smaller ones but I'm pretty sure the setting of prices is still controlled by a central office no matter where you are..

If you don't believe me that one place sets the prices for all stations, just go apply for a job at a gas station and work there for like 2 days and you'll see...

[porsche22]

well, been filling the EL with CT gas since we had it.
gas mileage is still good, at least 600km per tank of gas.
I really think it's just our head playing with us.

Are you serious?? 600km!??!! was this during spring when the temps is perfect and you dont' need AC??

Cause when i drive from Windsor to Toronto (400km) I use one tank.. and that's pure highway driving.. I can maybe do 450km.. i don't want to run teh tank completly empty.. but i keep my speed at around 120km/hr it's a 5spd as well.

been getting it for the past few months(i think it also have to do with how much i drive the car as opposed to my dad). Depends on how much of a rush my dad is in i guess. If i were driving, probably even more mileage...lol...
Well, most of the driving goes from Mississauga to Markham and back....then all city driving. I'll say it's around...60% hwy and 40% city. It's an auto(better hwy mileage than manual...surprising). Most of the time you wouldn't need A/C unless u're trying to get rid of fogging on the windshield. The empty light comes on pretty soon. Like 10L before it's dry. So I always run it till it's past the red line and touching the E. When I fill up i still have 3-4L of gas in the tank.

If you're doing 130-140, then yeah, I get 450km on a tank in my 96 Civic as well. Speed makes a huge difference. Wind also seems to be a big factor.

But if I stick to 100-110 it's not a windy day, I'll easily get 600+ km on my tank.

If you can't get 600km on a 45l tank in a Civic or EL with relaxed driving, something is wrong.

In most vehicles, fuel efficiency starts to drop off in a big way over 100kph. I can get far better mileage in my Rav4 at 100 than at 140.

[binaryguy]

Hey Gang,

Well, I certainly love threads like this, always good info pops up eventually.

I've been tracking fuel mileage in all my vehicles for years, including which gas station the fuel was purchased at.

(I have a pretty big spreadsheet for anyone who wants to take a gander)

My conclusion.....not much of a difference. The only _real_ difference is the way you drive and the odd 'bad gas' you may have gotten (say water leaked into the pumps tanks...).

Didn't see anyone mention tire pressure yet either, nor consistent temperature/humidity. All important factors.

Example, last fall, we rented a 300C (Damn nice car! Got some pics of it here (http://www.dragondon.net) , including proof of 390 ft-lbs of torque! :twisted: , don't tell the rental company :cheesygri ).

Ok, so on the trip to Ottawa (from Toronto), I couldn't resist testing out all 340 horsies a time or two. So, the car went through an entire tank of fuel. I mean we're talking vapours by the time we found a gas station in Hull (Quebec, right beside Ottawa for those that didn't know). We took the 401 all the way there, speeds did hit 150 once in awhile ;) For the most part, cruising around 120ish.

Trip There: 72.4L for 441.2kms = 6.1 km/l

On the way back, we decided to take Hwy 7 for the majority (95%). Hwy 7 is an 80km/h zone most of it (60 in cities) and we cruised about 10km/hr over. Wife drove for about an hour.

Trip Back: 52.0L for 461.3kms = 8.87 km/l

That is a HUGE difference. I believe the difference even seems more than just the 10-20km/hr slower speed but that needs more testing to be sure. My biggest question is the type of gas put into the car prior to us putting gas in it. Previous person could have put in the cheapest gas found (despite the car needing mid-grade only), could have accounted for that. I'm sure that my 'slightly spirited' driving was part but I do have some concerns that it was 20L more!

As for the Canadian Tire gas debate, I'll say this: I've used CT gas in all the cars I've owned (74 Charger 318, 72 Dart Slant Six, 87 Caravelle 2.2 Turbo, 2000 Neon 2.0L) and never had any noticeable complaints or problems. Not great gains or losses in fuel consumption. And seeing as I worked for one of their franchises (Part Source) for a few years, and knew the accountant for a CT store, they definitely used Imperial Oil (ESSO) for their gas.

That being said, I will never buy gas from 'no-name' places. Mostly because of the lack of additives and 'quality control' over their franchises/independants. This has served me well to day.

As well as when PetroCan had issues with Aerostar fuel pumps and their 'winter gas' (seems that ford's rubber was allergic to the alcohol that Petro used) I've always stayed away from Petro. This may be unfounded but I'm not intersted in finding out if it's true or not.

While we're on this subject, I'll also take a stab at 'performance' fuels.

Anyone who believes that higher octane will give your car more performance is deluding yourself. There is a catch :) If your car was built to take advantage of higher octane fuels, then yes, you will see a difference. If not, then you will also see a difference....in your wallet.

Example: Owners manual in my Neon states to use nothing higher than 87 Octane. Owners manual in my parents old 94 Concorde stated that it could use any but a higher octane would net higher performance and mileage. Bottom line, read your owners manual.

As for a general opinion on the 'best' gas for those cars that require it, Sunoco 94. Pretty common to hear that from guys who have big V8 older cars that are tuned to 400+ HP.

Of course, this is all from my own 20+ years of driving experience. Take it or leave it :) I just hope you found it informative ;)

[FastFokker]

Alot of great information in there binaryguy and I think I would agree with it all... especially this part:
Bottom line, read your owners manual.I'm rather tired of hearing lazyboy engineers who seem to know more than the people who designed, manufactured, tested and re-engineered the products.

They know the device better than you or I ever will.

[hytong]

SOmeone told me that it has to do with the ethanol content in their gas.

and that someone may be called Natural Resources Canada (http://oee.nrcan.gc.ca/transportation/fuels/ethanol/safety.cfm?attr=8)

[xien0n]

and that someone may be called Natural Resources Canada (http://oee.nrcan.gc.ca/transportation/fuels/ethanol/safety.cfm?attr=8)


They claim 10% ethanol as no effect but just by my own experience and all the posts here, it does seem to have an effect. Almost everyone says Sonoco give slightly poorer milage, so there's got to be something there. Btw, I only notice a slight difference with Sonoco gas, not the ~50% difference that the guy with the Mazda 3 GT gets - that's just crazy.

[odd person]

one month, $500 in Canadian Tire Gift Cards, one MY2003 sedan, better fuel economy than with any other fuel.

With the new Gas Advantage MasterCard it looks like all our gas will be CT

doing a little update...


i suppose there isn't much difference in the mileage between high octane (91) petro gas and Ct gas since i filled it up with CT gas all the way and got 432 kms compared to 425 kms from Petro

[ngignac]

I work at Canadian Tire and yes they're independently owned and operated.

[gman]

If you only get 400km, there is something with either your car or the way you are driving. I am driving a Montana, a mini-van, full tank is about 90L. For pure highway driving, I got around 1000km 2 weeks ago.

Did I say I am driving a mini-van with automatic transmission?

How fast are you driving your vehicle. That makes a huge difference. I drove from Thorold to Timmins this summer a few times. The first time I went to Timmins was on a long weekend so there were a bunch of police traps, I decided not to push my luck and set the cruise. I got over 600 km's on 96 freaken LHS. Now it was perfect weahter out, but when I came home at pretty much the same temp. I was doing between 125 and 135ish depending on where I was. I was lucky to get 450 km to the tank. Yeah my car is absolutly horrid on gas but if you keep it at 100km/h and set the cruise button on you will go a heck of a lot longer

[Evil Baby]

For those of you having issues with Crappy Tire gas, is it all one gas bar or a bunch of different ones all around? My dad who does about 75 000km a year uses mostly CT gas because he gets the most money out of it. He's never had a problem with it, but he only uses Premium and its mostly from gas bars in Hamilton or the Niagara Region

[Evil Baby]

Perhaps he has a beat up 96 Chrysler LHS....Oh wait that's me. I have a 65L tank and in the winter i'm lucky to get 400km on a full tank in the GTA. But that is GTA driving. So much stop and go, then when you do get going you don't want to limit your speed to just 100km/h to save gas. bahhhh, good thing I've reduced my driving only to groceries/laundry on the weekend and one day a week driving to work so I can sleep in an extra half hour

[jr!]

I drive a Y2K VW Jetta w/ a VR6.
I've been putting REGULAR CT gas in my car since I've owned it (4 yrs now, bought it used) & have had no problems.
Every time I take my car in for service I ask my mechanic to look at the fuel filter & pump, & he's replaced the fuel filter once, those familar w/ the VR6 know that VW calls for premium gas, minimum 91 octane in that engine, but I don't bother wasting the extra $5 per tank, that's what the knock sensor is for.
No point having a part on my car that doesn't do any work, is there??
:lol: :lol:
