Octane/station???

Zat_Zuma

Yes I know that's why I'm checking on it. (feel more important now?)

Did you also know that only northern Alberta SHell blends 87 & 89 have up to 10% Ethanol added whereas southern Alberta does not. (haven't confirmed that with marketing yet) 91 octane V-Power is still Ethanol free in north and south Alberta.

But that may change in September, 2012.

The addition of Ethanol to a 91 octane rated fuel is fine but still needs to be lab tested to insure of consistant quality and octane. I'm looking at the PetroCan Super 94 fuel in particular. Plus, I want to see if SHell is going to market a similiar fuel.

Up next is to talk to marketing and to test the Research octane and Motor octane rating of PetroCan Super 94 fuel. I want to know what the real octane # is on the Super 94 fuel.

Thank you for the reply Would 94 and 91 have any difference in them at all for our engines? I notice it's only like a $4 difference between the two for fill ups, if it actually helps then I wouldn't mind paying that extra $4 but I seem to be getting mixed responses from people

Maybe but the difference may not be noticeable. Nissan develops their maps for the ecu based on 91 octane for better performance and more importantly, the higher compression of this engine requires higher octane. At the end of the day, 94 octane will in no way harm the engine and may improve performance slightly. So it comes down to paying the extra few bucks per tank for little or no noticeable gain in performance unless you have the ecu tuned for 94. The tune does more than just adjust timing it also maximizes the afr and in conjunction with the timing curve, resulting in noticeable performance gains. You can also tune for 91 octane and gain performance.

So my tuner, members on the evo forums and myself are trying to find the cause of this...





Our conclusion thus far is i got some detonation/knock which caused the piece of the #1 piston to break off, which got caught in the intake valve. Which caused to not close correctly and ripped it apart.

I ran on 94 octane from huskeys for the first half of my tuning. Once my clutch **** the bed and i was waiting for the new one to arrive, i tried 94 from petro canada. Like my earlier post. I never had any knock on 94 from huskeys but got a few on petro canada. None the less i decided to stick with petro for the fact that its closer to my house and they offer the petro points. I was hoping my tuner could just lower the timing or something to get rid of the knock. However before he could, the engine popped.

Was Petro Canada gas responsible for this? who knows. But i have logs to back up my findings that Huskeys didnt give me any knock but petro did. So just be aware of what gas you guys use. My car will probably be down for the next year, defently wont be done by the end of the summer and i wont be taking it out in the winter after a rebuild since i have to do tuning and dont want to do it during the cold temps. So when the car is build (most likely to a 2.3 stroker) ill be running 94 from huskeys + meth.

you know that thought crossed my mind a few times in the past few months. I spent $7000-8000 of my tour money on my Evo build. I could have got a nice TT setup. Funny thing is, im making just as much hp as a basic TT build, yet i only have 4 cylinders and a 4 door sedan. If i didnt push my car past its limit, the engine wouldnt have blown but i knew it wasnt going to last. I'd eventually be in the same boat if i still had the 370z with a TT...eventually a blown engine. Besides, theres no good tuners for the 370z in Alberta.

I stated this in another thread somewhere warning guys about tuners - they're not all the same caliber. Some of them can fak your tune. Not sure if that was your situation but sh1t happens sometimes like your catastrophic engine failure. I guess at this point it doesn't really matter what caused the failure as it's now in the past but it probably was detonation.
