[Excerpt]
"...As an apocryphal aside, high-end VW tuner HPA has noticed that their roughly 500 hp turbocharged builds seem to do much better on US-grade 91 octane than on Canadian-spec 94. Perhaps it?s the blending process, but the US fuel seems to be less prone to knock, allowing for timing to be advanced and more power made.
That?s not the only regional difference. Gasoline companies will tweak their blends all across the country, depending on the temperature, terrain, and season. I?m reasonably sure gasoline in Nova Scotia isn?t cod-flavoured, but it will be of differing chemical composition than that sold in Calgary..."
