Where are you going to fill up?
 
I am just wondering where everyone is going to get their gas for the 370z. Also what premium gas/octane will you be running?

I have hit the flying J shell station (V power premium/91 octane) but I've heard that husky stations have the highest octane(94) but they are ethanol blended (~10%). My friend has a new WRX and he runs this fuel but I'm not certain if the 370Z would be compatible with ethanol blends.

Around here (TX), all fuel is 10% ethanol by law now, there's no avoiding it at the commercial fillup stations. Unless they built the fuel system different for Canadian fuel standards (unlikely), I would assume 10% ethanol will work fine for you too.

Sunoco's have 94.. at least here in Ontario they do

Zat_Zuma 04-21-2009 04:58 AM
Does anyone know what the octane is for the Chevron station in town?

WoZZer 04-23-2009 09:13 PM
I read in the owners manual that they do NOT like ethanol blend if possible. Alcohol is very corrosive to the fuel system. I'm running 91 octane Shell with the new V-Power additives (better/more detergents) and have no problems with knock or performance. I would rather give up on octane (above 91) if it is at the price of adding any alcohols. Try some 91+ and see if there is a difference. Good luck.

VertigoZ 04-24-2009 04:59 AM
How do you identify if a gas station has an ethanol blend or not?

ssqpolo 04-24-2009 06:16 AM
^^most gases nowadays have like 10% or less ethanol. DO NOT FILL WITH E85!.
anyway, i fill with shell or chevron always. premium obviously

Canadian370Z 04-24-2009 11:48 AM
I follow this: Top Tier Gasoline

It should say on the pump what the blend is if there are "oxygenates" or alcohols.

Drexster 05-03-2010 07:31 PM
Chevron is the only fuel provider in British Columbia that i know of that has 94 octane fuel. I've heard Husky has some 94 but it's ethanol blended.

CAN-ZED 05-04-2010 01:13 PM
Petro Canada just introduced 94 octane, my local station just put new pumps in last week

DjSquall 05-04-2010 02:09 PM
Is 94 octane really worth it?

Yes it is. Just try a tank full of regular and see just how noisy the engine gets ;-)

I'm currently running 91 octane, so I'm guessing it will be much better for the engine if I run near empty and switch over to 94? 1400km on it currently :) another 600 until first oil change yay!

Sorry, I thought you were referring to regular vs 91 or 94 octane. My mistake.

Ztoon 05-04-2010 03:42 PM
Chevron 94 with Techron

IDZRVIT 05-04-2010 04:37 PM
Living here in the a$$hole of Canada where there's no choice except for 91 octane at any station you choose, I take advantage of the Super Store pumps that give back 3.5 cents/L for groceries. But I've filled up with Sunoco 94 in Ontario last fall. Didn't see any noticeable difference in daily driving.

So would you still say I should switch to 94? My car is still basically brand new so if it will be of benefit, Ill make the change.

Is the Superstore gas okay to use? I'm almost ready to bite on a white 2010 370Z and that's where I usually fill up my Jetta because of the money back for groceries.

No, I don't think you'll notice any difference. I was saying that you'd notice a difference (pinging) with 87 octane (regular). No too great for those aluminum pistons.

But between 91 and 94...(?):ugh2:

djpathfinder 05-04-2010 09:01 PM
I fill up at Husky with 94.

FricFrac 05-13-2010 11:03 AM
Whoa hold on guys - you are wasting your money running 94 octane. I was under the same delusion for a long time. You get more power out of lower octane fuel but we need to run 91 to keep the engine from knocking because of our high compression. 91 is optimum whereas 94 is only needed if your car is pinging or knocking and if your 370Z is knocking on 91 you have either bad fuel or a problem with your car.... unless of course your car is boosted then you're gonna want to run 94 or higher :)

Yes. Superstore doesn't make gas so they buy it from Esso, Shell, Irving or some other refiner. I haven't heard any ping from engine in 22K kms. So, I'll keep getting my grocery coupons.

DjSquall 05-13-2010 04:51 PM
So I made the switch to 94 octane... Now it feels like I'm driving a jet plane.

Hi-Step'n370Z 05-13-2010 05:08 PM
I've been running Sonoco 91 octane, but after reading the posts, I'm going to look for a chevron, texaco or shell station.

I THINK they all use ethanol though, not sure.

Drexster 05-14-2010 10:54 AM
I don't mind spending the extra dollars on my gas. If they sold 110 I'd probably buy that instead :)

NOTE Chevron pumps in BC have a label on them stating "no ethanol".

:iagree: I realised that Sunoco 94 Octane doesn't improve any power and also it more expensive than 91 AND I get "less" mileage.

So 94 = more expensive + less milegae + ethanol... I am sticking with Shell 91 as it claims to have 0% ethanol (which I don't think the 370z wants).

IDZRVIT 05-15-2010 08:54 AM
The calorific value, amount of energy stored in the fuel, is not affected by octane additives. That's why we tune for more aggressive timing schedules and lower AFR's to get the most energy out of the gas and higher octane gas can assist in achieving more aggressive timing schedules.

Husky uses 10% ethanol. E-10 is corrosive to steel. Used to be called gasohol.
Basically you're putting moonshine in your tank.

lol you might want to go back to 91... 94 = less power not more...

The idea of octane level:

Octane delays the ignition of the fuel. So if you have 87 octane in a car it will ignite sooner than if you have 91 in a car or 94...

The lower octane level you CAN run in a car the more performance you get because the fuel is igniting sooner. However engines like ours need to build up enough pressure before the fuel can ignite and therefore our cars need 91 octane. If you put 87 in our car the fuel will ignite too soon and cause knocking and if you put 94 in the car, the fuel is not igniting at the prime time I.E its actually delaying ignition.

Octane rating has everything to do with how slowly the fuel burns and how resistant it is to detonating under compression. Higher octane = slower burn/more resistant.

This is compensated by advancing the timing. The car is "programmed" to use 91 octane fuel, meaning the advanced timing is already active. Using higher octane gas yeilds no benefit as the car can't detect higher rated fuel. *(this is true of all vehicles!)

If the car detects knock, (either by detonation or by the fuel burning too quickly/early by using under-91 octane fuel), the car WILL retard the timing and enrichen the fuel map until the condition is minimized.

That said, it says PLAIN AS DAY in the manual to use 91 octane (or higher) gasoline (again, not because higher octane gas will increase performance, but because it's safer in the sense that it's less likely to knock/detonate), but in case of emergency you can use 87/89 octane, but do not fill the tank, do not drive the car "hard", and fill the tank with 91 as soon as it is available.

So, RTFM.

Sibze, may I ask what qualifications you have to make your statement?

Sibze 05-17-2010 05:01 PM
Ok cool, Show me I am wrong. Please

http://www.wisegeek.com/what-is-high-octane-fuel.htm

http://www.ftc.gov/bcp/edu/pubs/cons...tos/aut12.shtm

http://www.saltwatersportsman.com/ar...board-Gasoline

I like this part in the first link:
"Basically, you’re wasting your money if you buy high octane fuel. You should start off with the octane level your car’s manual calls for; if you still hear knocking or pinging, you might try the next step up. If the problem persists, you’ll probably need to have a tune-up or some diagnostic work done. Don’t think that putting high octane fuel in your little Toyota will make it run like a race car – it just doesn’t work that way."


Ok lets see something that says I am wrong... I will switch tomorrow if 93 is going to make my car faster...

Sibze 05-17-2010 08:28 PM
Edit: I found a really good link.... http://www.wanderings.net/notebook/M...sWorthTheMoney

"Does High Octane Gas Give More Power?
No. Unless your car is explicitly designed for high octane gas (see your car's manual), using a high octane gas will NOT improve the power output of your engine. Again, the octane rating relates to how much energy it takes to ignite the gas, but NOT directly to how much energy the gas puts out. "

As far as i know, theres no stations around here that sells E85, if there was i would have had my old car tuned for it..lol

That's kind of like asking someone who isn't a doctor what qualifications they have to claim that eight glasses of water a day is good for you. It's fairly common knowledge - enough that you don't really need to be an expert to make the statement. A simple Google search should give you hundreds of articles on the topic...

Sibze 05-18-2010 12:16 PM
