Hey guys!
I was just wondering where do you purchase gas? Also what octane does the Z32's like best? Most places offer 92 octane (if that's even the right rating for premium gas, haven't been at the gas station in a while lol) but there is a Huskey that a friend said that sells 94 octane...I bought my car from White Rock B.C, and they have a higher octane over there. So would my car make the adjustment to the octane difference by itself? As for me, I use Petro or Esso’s Premium gas...most of the time it’s Petro.
Happy Holidays! |

Most premium in Edmonton is 91.
My Z likes Shell Gold (91). |

You should use at least Octane 91. Most Mohawk's / Husky's in the city have Octane 92.
A few have Octane 94:
Cherry Grove Husky 15303 - 73A Street
Anthony Henday Husky 19820 - 62 Avenue
St. Albert Stop N Shop 192 St. Albert Trail, St. Albert, AB
I don't think it is that big of a deal, as long as you use Octane 91 and it isn't stale. However, if you are going to be using the engine at high RPM's and/or full-throttle for extended periods of time, it would be a good idea to use a higher octane to avoid detonating the engine to death. |

To sum up what Mash is saying... Just don't be a dumbass and try to run 20 psi of boost on 91 octane pump gas! ;)
(Actually on 91, you should try to stay under 14 psi.) |

Exactly. It's like this one post I saw on another forum:
Person A says, I am hearing this metal clanging sound at wide open throttle. I just increased my boost to 14 psi.
Person B (jokingly - but very mean thing to say), says why don't you try increasing your boost to 16 psi and see if it goes away.
I am sure it will go away permanently. :) |

As Mixmanmash listed, there is 94 octane available in Edmonton. It is ethanol blended fuel, and some people have issues with that in Z32's, especially running older pintle style fuel injectors. There has been some documentation that ethanol in fuel can cause injector failure and some discussion about this on tt.net. Do some google searches on fuel injector failure and ethanol and you'll get some better answers.
However, I can personally attest to improvements in boosting using the 94 blended fuel over 91. I had been dropping to safety boost on the highway pulling hard in 5th gear on 91 octane. No audible detonation, but by the second pull, the car wouldn't pull over 7 PSI and was sluggish due to retarded timing. This was consistently happening last year and this summer on highway trips, but not in 1st, 2nd and 3rd gear pulling driving around the city. I repeated the highway experiment with a fresh tank of Husky/Mohawk 94 ethanol blend. Did several pulls from 100 km/h in 5th and pulled to 12 PSI every time. No other changes were made to the car. I run 94 when I'm autocrossing or dynoing, or feeling rich, given the high gas prices this summer. 91 now in the winter with less boosting happening.

lol. take advantage of the cooler air in winter eh? That must be nice to avoid heatsoaking and get cooler air too.
I noticed a big difference with Octane 94 as well. My car ran a lot smoother at the higher RPMs, under hard acceleration, and in 5th gear at hard accel.
The main problem with ethanol blended fuels is that when you burn it, it creates oxygen. This in turn returns a higher oxygen value to the oxygen sensors. Which means the ECU tries to lean out the mixture. However, at 10% ethanol blend with the Mohawk stuff, it doesn't make that much of a difference. In fact, if you read the owners manual, they say up to 10% ethanol mixture is fine.
Just don't go beyond 10%. Most cars that have been made to run on ethanol from factory (I know Ford sells some vehicles in Canada that are designed this way), have a different ECU software so that the O2 sensors don't trick the ECU into running lean while using Ethanol blended fuels. In fact, Ford also sells vehicles that will run on normal gasoline as well as ethanol. |

Thanks for the info! I just moved to Edmonton in October and I had no clue that you could get anything above 91 Octane!
Thanks for the post! :)
