Petro Canada Ultra 94. Yea or nay?

Jordo!

The ethanol content if its < E10 is pretty negligible -- it more like any odd hiccups (random miss) might be attributed to it in the absence of a better explanation, but really its fine.

The 94 octane (assuming AKI rather than RON) is worth it if you are tuned and running a little more ignition advance or the car sees hot laps on the track -- otherwise, I doubt you'll find much of a difference in power either.

On the other hand, it certainly won't hurt -- what's the price difference compared to 91 and can you get 93?

I also use 94 but original was using shell 91. When I got the car tuned the guy said he would recommend the 94 "if it was him" he said. He explained there would be less engine knock and burn just that little bit hotter which is a good thing

I figured, you know what he knows more about that crap then me, after that I made the switch

Cooltoy - I have noticed at petro-can when you look at the grades of gas the 94 does not have any mention of ethanol on the label/sticker/sign for selecting grade. Where the lower grades are one big label/sticker/sign that covers all 3 grades and that sticker has the **may contain up to 10% ethanol. I think what ta-kid posted is correct no ethanol and the fuel is coming from a chevron refinery.

At the end of the day, use whatever octane you like as long as it's premium being put into your Z. Now, if you're someone to complain about the difference in price per liter, why buy a sports car?
