what kinda of gas do you use and find best?

[Prezi]

Mainly costco and petro. Shell if I go to visit in-laws. Full tanks gets me about 750 to 800kms. I drive like an old lady.

You drive a mazdaspeed and get 750 - 800km on a tank??

[Ghost1]

According to my car yes I do. I try to never hit boost. I drive speed limit. Keep my car light ( not carry extra stuff I don't need). And I shift at 2.5k rpms.

Forgot to mention car is fairly new and I add extra 5l when I fill up

I got really close to 750km\tank, but then it got freakin cold and stayed that way since ... so I've stopped chasing the 750km tank on mine.
Mind you, that was boosting here and there if\when I needed to get ahead of a 90km\hr car on the highway, but mostly cruising at 100~105km\hr when traffic is flowing.

That being said, its a hoot to let her rip when you don't give an F about gas mileage, and you wanna keep your sanity in check from bordem. :)

esso on woodbine and 16th now has 93 octane. very interesting. what would the diff be between 93 esso and 94 sunoco/petro be aside from the 1 octane rating diff anyone?
its also cheaper than the 91 which begs the question why?

It takes time for the engine to get use to the different brand of gasoline. I believe this happens because of different additives used in the gasoline, which vary by brand.

Apparantly shell is the cleanest gas. My brother did a road trip and got 100+kms more on a tank of shell gas than I believe it was esso gas. Take into consideration a few more stops, maybe some wind, and that's still a huge difference. Both tanks straight across Manitoba and sask

I get 100+ more kms per tank when I use Indian reserve gas lol....I hit 100km before touching the full mark lol....

Anyways, before I got my 3 I did some research and also found Shell to be the cleanest gas, (gas available to us here in the GTA), but that was back then. Not sure if its still the case now.

Cosco gas works for me :3 this days I noticed gas prices was insane $1.39/L >.<

[WHO]

Try to use ethanol-free gas when available. Almost impossible nowadays other than buying Super.

700+ on tank is possible, at least with the 2.0 MZR engine. I did it last year when I drove to South Carolina. Closer to ocean level, much better gas blend, and I did about 730km on a single tank mostly doing 130 on flat highway.

Just last week, I did 674km on a tank, driving on mountain roads of Maine, New Hampshire, and Vermont. That was after driving 48.2km after the last bar went out. I then filled 56.08L in my 55L tank. I guess I was running on fumes by then.

[scky]

I've only been putting Petro 94 into the wifey. I usually get about 410-460 on a full tank. The most I've every gotten was 660 when driving to pennsylvania.

[bestknightmare]

I use Petro, Esso, Shell (whatever is near my home)'s low grade, and I can get 800km. But I do mostly highway driving, at 100kph. I heard that it doesn't make much difference if you use a higher grade. Then again, there are some parts with stop and go traffic. I normally fill it when there's 2 bars left. Heard that going completely empty will wreck the fuel injectors.

[sarujo]

Unless you are driving a speed you are wasting your money with anything other than 87 octane.

PA is normal you get higher mileage. You reached different elevation and the air density is different. Everytime I drive South I get much (significantly) better gas mileage. The best I ever got was close to 6L/100KM driving in VA, all the way to SC. And that was going about 135km/h on the highway which is tolerated over there (PSL being 70 mph). Also in those States many gas stations still offer ethanol free gas which improves mileage even more.

[Canadianbacon]

Not only speed use any 87. I'm running a 91 tune on my 2.5 2nd gen

Petro Canada 87 Octane (Regular) for my MZ3. I try to stick with a brand that I know are a Top Tier company that way I know I'm getting a good gasoline, and I'm sure the extra detergents help out as well.

I use shell and get 600km a tank easy on regular.

Use what your manual says to use.. if it asks for 91 use 91 if it asks for regular use regular or up... higher the rating the better mileage youll get. try using some fuel injector cleaner "lucas oil" amazing stuff. try doing a tune up also.

keep in mind those who use 91 or up that if you run it all the time and go to a less refined fuel like regular your vehicle will run like crap! its okay to run it once and a while but to run it all the time and switch to regular the motor will run a little rough.

if you run a fuel injector cleaner that isnt the while bottle of lucas oil. do it before you change your plugs.. the chemical in most actually destroy half the life of your plugs.

[WHO]

You quoted out of context, but I agree.
Even if the manual says 91, if you put 87, you most likely won't see a lower MPG, but reduced performance (nowadays the ECU will simply re-calculate the air/fuel ratio and other performance management which will lead to fewer HPs). Not a great difference, though, say 240 vs 250 HP...

[DreCyrus]

i put shell regular in my car and it seems to give me to the most ams about 400+ if I'm lucky and depending on how much driving i do within the week I've never reached 500+ doesn't even seem possible with my car. When i use Petro or Esso I last like 3 days max. I heard costco gas isn't that bad might try it out.

[Prezi]

been using 94 octane from petro Canada... works good for me. Could prob get 400 - 450km.

[jeffjones]

any 87 octane gas gets me anywhere between 550-600kms on my Gen 1.

[Reddie1337]

If your car is rated for premium you should run premium, if it's rated for regular, run regular. I did a test of this over 6 tanks, I ran premium in my gen 1 for 6 tanks, did an etest before I started the test, and after I ran the premium, and my emissions went up (fuel not being burned) and my mileage went down. I run regular, because the car says regular. If you have been tuned for something different, you should use whatever you're tuned for. And also, we've run regular through 2 cars that called for premium (BMW and Infiniti) they both had engine lights for o2 sensors, or cat. So the fuel being the wrong grade isn't good for a vehicle. In higher end vehicles, it causes sensor problems.


(This was an informal test, I didn't document everything, just noticed mileage went down, and I compared the etest numbers) (this was before the computer controlled testing)

[ryan2.3]

4 of my last 5 tanks have been some of my best yet.

2004 2.3 M/T...
filled up at BP with 87 and drove to pittsburgh. I got 7.7L/100km on almost all highway (about 50km was city, the other 550 were highway). On the way home my wife wasn't paying attention and accidentally put in 94 at a Sunoco (it was ok, it's only $1/L in Ohio :chuckle) and i picked up 7.5L/100KM (about the 200km city, and the other 400km highway). Couple days later, i hit 7.1L/KM (about 75km city, the rest highway)

I've seemed to have settled into a sweet spot in the lower to mid 7's. I usually fill as soon as the light comes on. I'm doing between 550-610 from full to light on, which is about 45L. Don't drive slow either.. given the highway limit is 70MPH, i'm usually doing between 75-80 (120-130) to keep up with traffic

Had a couple bad tanks (was teaching a friend to drive a manual so we had a couple hours of idling and crawling around the neighbourhood :( )

I'm trying to get my wife to make sure to keep logging since i know she could be better in the Gen2

[Firefox444]

If your car is rated for premium you should run premium, if it's rated for regular, run regular.

+1. There have been countless industry tests done and running an octane higher than what your engine is rated at is just burning money.

I've used 94 octane in my stock RX-8 for a long time, but I honestly think the car runs as well (if not better) on 91.

[Booter22]

Reddie1337 When is a good time for a fuel injection flush? Is that what he means by getting the valves cleaned? Or are they two totally different things?

Jackal

Two different things. Direct injection engines put fuel right into the combustion chamber, so if you put an additive into the tank, it's not cleaning the valves. A fuel system flush shouldn't need to be done for a long time. Or if you have water in the fuel. You can add additives with a high octane boost to try to clean it up, but as long as you use a reputable gas station, you shouldn't have much problem. If you are cleaning valves you have to do it though the intake, but that's risky if you don't have much experience, because if you use too much cleaner, you can hydro lock the engine. I've actually been thinking about taking my intake off to clean it up nicely. More work, but you can see the intake valves so clearly.

[Jackal]

Thanks Reddie1337 It was one of the things that the service advisor mentioned I should get. Haha. Another thing to say no to because I know the car is running great and I only use Shell or Pertro Can gas. He also mentioned I should change out my spark plugs.

Those are 2.50$ each at RockAuto now. 5$ from RockAuto minus 2.50 MIR from Autoline per plug. So you can have about 20 plugs for the price of 1 OEM.

The NGK are 10.50 each...

Seriously though.. for what the plugs do and how often you replace them why would you want to go cheap? I mean sure the oem plugs are pricy. But the car get that once every 5 years or 120 000km.

[Sendarian]

Shell, Air Miles has sucked me in! Also the guy that works at the shell near my place responds with "insane" when I ask how he is doing. Makes for a good laugh every time :)

[m_bisson]

I had some thoughts during a boring day at work, so I did some research and this is what I found!
Also, I'm doing this from my my phone so it's not going to be as long or in depth as I'd like....

The octane rating doesn't have anything to do with how much power the gas can produce. It doesn't give an indication of how much octane is actually in the gas, either. I'm sure a lot of you think "Oh 87 percent octane, must mean that 870 milliliters out of every litre is pure octane". Doesn't work like that. The '87' is a rating of how the fuel will resist "knocking" in the engine, compared to pure isooctane. There are some fuels rated OVER 100, which resist knocking better than pure (100 percent :p) octane.


What is knock? The gasoline in the combustion chamber doesn't all ignite simultaneously. A small ball of fire starts at the tip of the spark plug, then a wave of flame expands outwards in all directions. The remaining unignited fuel in the chamber is compressed as the other fuel ignites. If it gets compressed enough, it can "self-ignite" before the flame from the spark plug reaches it, causing a secondary combustion. This is "knock", and is incredibly damaging to an engine.


Now, if you take 1 litre of 87 and 1 litre of 91, they will both produce the same amount of energy when burned. You simply CANNOT create energy where there isn't any to be created. If you take a litre of 91 and put it in a Toyota Corolla, then put a litre of 91 into a Porsche, the porsche will be able to extract more of the available energy from the gas. This is just due to engine design, not because of the difference in fuels. If it was possible to burn 87 in the Porsche without it knocking, it would produce the same amount of power as the 91.

The only reason to use higher grade fuels is to prevent "knock". Our cars, and even more modern 'high-end' cars will run perfect on 87. Newer cars have computers that can adjust for lower grades of fuel, even if it calls for premium.
Higher power, performance engines will create a lot more compression in the combustion chamber, especially if there's a turbo or super charger involved. This added pressure will almost certainly cause regular 87 to "knock" during ignition. Our cars do not create enough pressure (compression) for this to happen.
***If you're reading this, and your vehicle knocks with regular gas, then something is probably wrong with your engine***

Tuning: some of you have changed the timing on the engine. This may or may not cause knocking with regular fuel. If it doesn't cause knock, then you haven't increased the effective compression enough to warrant the use of a higher grade fuel.


Tl;dr

The best thing you can do is run the lowest rated fuel you can that doesn't cause knocking.

Edit: this post is assuming an ethanol-free fuel. If you compare an 87 with ethanol to a 91 with zero ethanol, then of course there will be a difference in mileage! Ethanol has less energy than octane, and will decrease your mileage by a small amount. But really, a small amount; likely less than 1mpg difference.

Edit again: It doesn't matter if it's ethanol-free 87 or E10 87. 87 is the anti-knock index number. You're engine should not be having issues with any 87 rated fuel.

[Reddie1337]

Yeah. The last time I ran 94 in my 2.3, all I did was burn more gas, it decreased my mileage. So your post seems accurate.

[asyed]

+1 on the ethanol thing





Also overtime ethanol can be potentially bad for your engine by wearing down various seals and possibly gumming up your engine.



I myself have converted to shell 91 as its the only fuel with no ethanol. I would fill up with 87 but most 87 in Ontario has ethanol.




Also on. A side note... Petro 91/94 is not ethanol free.

E10 won't harm your engine or fuel lines unless your car was made pre early 90s. Ethanol or some other oxygenate (others having been banned due to doing more harm than good) have been in gas for almost 15 years.

Manufacturers have long since accounted for ethanol of at least E10 to E15 in fuel lines, fuel pumps, and engine seals.

Higher concentrations in a car not designed for E85, on the other hand, have shown to gum up high pressure/cam driven fuel pumps.

Switching to Shell 91 in a car specified for 87 is throwing away money... Unless you've done the math and have shown that the extra kms/tank gained from Shell 91 more than offsets the cost of 91 vs 87

I don't know if its psychological but I've noticed a significant boost in fuel economy since switching to shell (driving habits did not change)

Yes modern engines can withstand E10/E15 but for how long. Manufacturers don't expect cars to last long and they don't go too out of the way to prevent damage from ethanol... They only try and slow down the process.


Besides I'd rather pay an extra $10 for prolonged engine life compared to paying hundreds more for replacing seals etc.

Go read my post again. That's based on almost 4 hours of research! Lol. I scoured the Internet before writing that, and I'd sign my name at the bottom as a testament to its accuracy.

If you ignore the advice in the post, you're a total lost cause.

+1 on the ethanol thing





Also overtime ethanol can be potentially bad for your engine by wearing down various seals and possibly gumming up your engine.



I myself have converted to shell 91 as its the only fuel with no ethanol. I would fill up with 87 but most 87 in Ontario has ethanol.




Also on. A side note... Petro 91/94 is not ethanol free.

Semi-true.

Petro stations that carry ultra-94 have 91 grade that contains ethanol. Petro stations that DO NOT carry ultra-94 have 91 that is ethanol free.

Is that still true?
"Ultra 94 contains ethanol. Due to the fact that various fuel grades are blended at the point of sale, most grades of Petro-Canada fuel may now contain up to 10% ethanol. This represents a change from the previous state, where premium fuel was ethanol-free at Petro-Canada."

As far as I'm aware, what I stated was true and still conforms to their FAQ.

Most grades of Petro Canada gas DO contain ethanol. All 87 89 and 94 do. Many 91's do, but at stations with no 94, 91 is ethanol free.

My 2 cents is Esso. Get an Esso Extra card and start getting points for car washes. You'll use at least 91 so you'll get 3 points per dollar. 600 points = Luxury Wash. ($200 in gas is a free wash.)

Second to that they have the option for 94 if you're tuned for it which is 4 points per dollar on gas so you'll only need to spend $150 on the 93 to get your wash.

Oh and thirdly, until the end of November I believe, they are offering double points. So 6 points per dollar on 91 and 8 points per dollar on 93 which means you're getting a free car wash for every $100 on 91 and ever $75 you spend on 93.

...because no one wants to pay to use a wash bay in the winter when a touchless is free.

I use Petro for my washes, 6000 points is your basic wash, and if you have the Petro-Points MasterCard, you get 1000 points for every 100 dollars, so if you use it to pay some bills and stuff, you can get a free wash, (I do it with car parts, over 390000 points already) also saves 2 cents a litre on every litre you buy.

[P1TA]

Petro, solely because their ATM's are CIBC and Petro points = mad free coffees

[brucewayne]

i use petro now because they will give me points for smaller purchase $10-15 which i need for my motorcycle. i have my petro points linked to my CAA plus so i get 20% more bonus points. then i trade my petro points for CAA dollars to help pay my membership.

Shell v-Power.

[Cab0oze]

I had some thoughts during a boring day at work, so I did some research and this is what I found!

What is knock? The gasoline in the combustion chamber doesn't all ignite simultaneously. A small ball of fire starts at the tip of the spark plug, then a wave of flame expands outwards in all directions. The remaining unignited fuel in the chamber is compressed as the other fuel ignites. If it gets compressed enough, it can "self-ignite" before the flame from the spark plug reaches it, causing a secondary combustion. This is "knock", and is incredibly damaging to an engine.

very good post, hopefully people read it. Only thing I think you missed is pre-ignition/detonation which could also be caused by low octane fuel on a high compression engine. Similar to knock, but instead of the spark induced flame front and the second compression induced flame colliding, there is only one burn, occurring even before the spark fires. This would happen in an extreme case and would essentially dive your piston the wrong way. However the remaining pistons would force the piston that experienced the pre-ignition in the right direction anyway creating tremendous stress on the components.

...just in case you're interested...

[sarujo]

Your SKY does not require high octane fuel - only 87. You're pissing your money down the drain...

Lol and I'm ok with that. In my opinion the v-power feels much better than the regular fuel.

Not to mention the air miles points you collect is pretty cool.

The V-power, how many k/tank are you getting? Cause I know in my 2.3L it actually decreased my fuel efficiency.

[Anthony_FA]

Feels? Are you bathing in the stuff? LOL

Yeah, twice a day. Haha

No but in all seriousness I've noticed the car just doesn't feel right on regular fuel. I don't really know how to explain it. I spend A LOT of time in the car and have been kind of a/b-ing this over the last few weeks and I do notice a slight difference. And I'm talking about a full tanks worth with each type of gas.

Not to mention the prices around here have actually been pretty low lately (some areas of Vaughan). So getting the v-power stuff even at 120 (ish) a litre it's not like I'm breaking the bank to put it In. Doesn't bother me to spend a little extra to get a little extra.

[Anthony_FA]

The V-power, how many k/tank are you getting? Cause I know in my 2.3L it actually decreased my fuel efficiency.

This is actually something I'm keeping an eye on. The last half tank I filled up on v-power and my k/tank was showing around 650ish. Which is unusually low. I mean, I'm a little heavy footed so my k/tank has dropped significantly (I remember when it was at over 800.....now I'm lucky to get to 700ish).

But yeah, I'm keeping an eye on it. It is something I noticed.

[sarujo]

Please stop with the km/tank! Everyone should be using Fuelly and/or properly calculating mileage in L/100km or L/km

[Jackal]

I get about 475-550 km per tank on 87 at Shell.

Your loss of fuel economy could be directly due to you using 'premium'. The write up above was good but missed an important thing; Premium fuel burns slower, meaning it is designed and requires a higher compression to ignite. Now if your running a slower burning fuel in a lower compression or unboosted engine, it is quite possible not all the fuel is igniting in the chamber and actually lowering efficiency and torque. The computer will compensate somewhat, but not completely...Extended use could literally gum-up and /or carbon up your valves, pistons and cylinder walls, which can eventually turn to varnish, which will cause issues down the road....Something to ponder anyway. :)

Thanks for that insight. I guess the higher compression in the 2.0 sky's still isn't enough to make a more premium gasoline like this work efficiently?

I'm definitely going to do some more research.

[Reddie1337]

I was just saying k/tank to see what if any change. I use fuelly, have since I got the car. I'm averaging 7.1L/100k. This past tank must have been some bad gas though. 300 to half where I usually get 400.

Nope. Same for me. It's winter gas!

Lol understandable. Instead of using 'premium' every five fill ups; If you ever have a couple of hours to kill take a nice country drive up to lake Scugog (the reserve) they have a station up there just past the Casino and all their gases are ethanol free, even the 87 octane!...I find I get an huge increase in fuel economy when I use their gas and they are usually much cheaper then anyone else and my engine seems to run smoother, plus you get to take a nice drive at speed, part-way anyways.

What is the difference between the basic and luxury wash? ie. what extras do you get and is it "worth it" for it?

I have 500 points (enough for the basic).

[6strings]

Let me help you with that :)
The luxury wash comes with under spray with rust inhibitor, you are given 15 seconds of that. Then presoak and the 1st high pressure rinse.
After comes the Trifoam shampoo and the 2nd high pressure rinse.
After all that is done the shine guard comes on with the spot free rinse to help protect the car from UV Rays, water spots, and dirt/grime.


Full wash has under car spray (no rust inhibitor), presoak soap, one high pressure rinse, clear coat/spot free rinse.

Quick wash is like the full wash but with no under car spray.

During the winter time the luxury wash is the way to go, it's worth the 599 points, and helps keep your car looking fresh.

[DominicMS3]

well I have to put in Ultra 94 due to my tune so I only use Petro Canada, even before my tune when I was using 91 I always use Petro, I find shell gas doesn't last long and I don't like esso. Don't use pioneer its cheap but cheap isn't always good especially if your car is a performance car. As for car washes I go to an indoor hand wash on Midland and Lawerence (meet spot maybe?). I find drive tru washes always miss a spot especially if your car is rustproofed, and I don't trust risking my rally armour flaps to a automated machine which seems rough not to mention my stickers.
