What will 100 octane gas do?

[Jaxonalden]

High octane fuel doesn't necessarily burn hotter, it's simply more stable than lower octane fuel. That's why high compression engines (ours) and forced induction engines (turbo charged and supercharged) need high octane.

If you run 87 in the for mentioned engines, without a knock sensor retarding the timing, you'll damage the engine because of pre ignition.

The engine will be livin' the good life on 100, Europe has 98 everywhere and I can't tell you how well 1.1 and 1.8 liter cars run.

P.S. Adam, damn nice car!!
