In an effort to save a little bit of money due to the rediculous gas prices that this summer will hold ($1.50 a litre??), i am thinking of getting a petro-canada credit card. it saves 2 cents a litre, and usually i find good prices at their stations to begin with, and plus it gives points that can be combined with my president's choice card...ANYWAYS.

what i am wondering about is, they put a gasoline detergent additive in their gas called Tactrol. does anyone know if using this gas is fine? i would imagine it would be fine, but just checking if someone knows something i don't about it. i currently premix my gas.

ive never bought gas there!

ever.

there isn't one here so I just don't.
but I don't see why it would be a problem, for the most part (esp. with n/a's) gas is gas.

I personally prefer Sunoco no matter what car I'm filling up. I've actually noticed a difference when filling up there as opposed to say Esso or Petro. Gas mileage is a bit better, I get maybe an extra 5-8% miles to the tank.

Plus, there are 3 Sunocos around me, the one I always go to is almost always 10-15 cents cheaper than anywhere else (I fill up at night, so when others put their prices up for the next day, Sunoco still keeps theirs down), and if not, it's usually at least 2-3 cents cheaper. 2-3 cents per liter isn't enough to justify me driving for 5-7 minutes to fill up there, but it's on my way home from almost anywhere I go, so I usually end up there anyway.

Not to mention they have 94 octane

I blew 40 liters of that in 150kms on my TII :P

in my town the petro-canada usually has the same price as everywhere else and it would not be out of my way to go fill up there. in Ottawa there is usually one petro-canada that is cheaper than most places.
but yeah, 2 cents a litre is hardly all that much.

Terrh, i was refering to how added gasoline detergent reacts with premixed oil, not really the octane (which is a turbo-issue, not NA). not all gases are the same, there are differences, but yeah, there is probably nothing noticeable.

I just fill up with whatever's cheaper, Petro-Can, Esso, Chevron, Shell, Super-Save, whatever. I've never noticed a difference. I've tried 91 once, again no difference (other than the price). You may be able to "find" a few hp difference (2?) on a dyno, but test conditions would change the hp more than the gas most likely. You'd never notice the difference without instrumentation, unless you want to feel it, then the mind can trick you into thinking that there is a difference.

For the NA any 87 should do just fine, I don't think that any addative would do anything with the oil, remeber, gas and oil (non-synthetic anyway) come from the same place (crude oil), so why would they react differently?

I've never noticed a significant difference in mileage between PC and anywhere else...


http://en.wikipedia.org/wiki/Tactrol


'Tactrol' probably falls in the same category of bs marketing ploys as vitamin-enriched shampoos. And if they actually put any kind of decent amount of this mystical additive in their gasoline, wouldn't their gas be more expensive than the other stations?

i don't really care about octane, and i have not experienced any significant difference between mileage from various stations. so really it comes down to this Tactrol crap.

but Amur is probably right...this "additive" they claim to put in shouldn't be anything to worry about...i don't think they would risk making a gas that was that radically different from other distributers. i was just worried about it screwing up the premix oil.

Petro-Canada..They came out with the "Winter Gas" also..did they not..I think that their research would be enough Clout..But I don't think that anyone has really Taken a whole Pile of Just RX7's and researched How they run on Gasoline with detergent( additives from the plant).Honestly,if the Boingers can Burn it..WE should be able to..I would think that the Premix would be the Extra Step to "counter-effect" any Residue left from the detergent.(just my opinion.I think..lol).

Hellbreed

From my experience with the RX-8 I get the best gas mileage from Petro Canada gas followed by Sunoco. The difference between Petro and Esso for me is about 40Kms per tank, sounds crazy but it's true.

Aaron, Dont get a card just to save that 2 cents.

Use the PC mastercard and youll get more than that in grocery points, etc.

Wankels-Revenge

i ONLY run on petro canada...haha

My parents have the card so i use it as well...been using it with every pile of crap i've ever driven. I have never experienced any problems with their gas.

Keep in mind i only run a stock n/a.....

let me explain again:
- i already have the presidents choice card
- if you use the petro-canada card, you get the same points as the presidents choice card (they can be combined)
- i have to buy gas anyways...and its always the same price in this town as anywhere else. may as well save 2 cents.

i would only use the card to buy gas.

Aason, you worry about the strangest stuff.

But, should the Tactrol **** up your engine, make sure you collect evidence and are able to prove it. Then sue Petro Can, and use the money to buy an FD.

haha.

you know, i'm reading my own thread and you are right...must be the exam-induced brain haze...i'm sure i have some psychological condition.
speaking of haze, i got my car out of storage today. mmmm, premixed rotary gas fumes.

i just got an idea though, i am going to get some gas from petro-canada, put it in a beaker, and mix it with the proper ratio of my premix oil. i'll let it sit for awhile and see if anything wierd happens. then i'll burn it...just for fun.

Last time I looked under your hood, at last year's Ottawa Meet, the only things splitting were the vacuum hoses.

I use PetroCan gas when I can.

I find when I use PC gas I never have problems, whereas with Domo, FasGas, Co-op, etc. I've had a few problems with water in the fuel. In winter this can lead to an ice pellet forming in the fuel filter, leading to fuel starvation. In summer it just means your car will run like crap.

Crappy Tire gas with their mastercard is discounted more than 2C/L. Plus you get 1% of all purchases in crappy tire money.

From what I've read there is a difference adative packages, but the main difference is how likely it is to gum up your injectors, etc. There is an initiative set out by the auto manfacturers in the US to have gas certified as higher quality. The auto manufacturers found that there were fewer warranty claims in certain areas that had certain types of additive packages.

Keep in mind that there are regional differences in gas. Around 5 years ago the federal government did testing on gasoline for environmental purposes. Sunoco gas was typically the cleanest. Ontario Esso gas had around 5X the amount of sulfur compounds in it than Sunoco gas. Alberta Esso gas was only around 50% worse than Sunoco gas. Different refineries produce different calibers of gas and I suppose the input oil probably matters as well.

As for the grades of gas, Car and Driver did a test and found that higher octane gas could produce less power in n/a applications than lower octane. Those results stand to reason, the higher the octane, the less volitile the substance.

Manntis

yup, that's why the RX-7 gets 87 octane, the Dodge gets 89-91.

In the US, where regulations are different, a lot of the 'additives' are complete bunk - if they even exist. @ least I know PetroCan gas with gasline antifreeze actually has gasline antifreeze in it

hey that's not true...and even if it were, i've replaced all vac hoses

anyways, good info Snrub about the gas study...definetly different regions will have different qualities, and it's really hard to say one place is better than the other unless you test it every time...

yeah, i saw that Canadian Tire card you can get...i never really trusted their gas (oddly it seems i always get less mileage), but i'll look into it. if anything this thread has proven that you can't know anything about gas going into your car, no matter where you buy it from
