Octane is the fuel's resistance to knocking. They put additives in it that make it slightly harder to ignite. The higher price reflects the price of those additives and how much extra that people who actually think that it is "better" fuel will pay. The V6 may have 11.3 Compression, but it is direct injected, which changes everything. In most engines, knock occurs on the compression stroke, when the fuel is ignited either by the rising pressure or a hot spot in the cylinder. In a direct injected engine, this can't happen. There's no fuel in the cylinder during compression. The fuel is injected directly into the combustion chamber at the last microsecond before ignition occurs. This also cools the cylinder which further reduces chances of knock. This is why direct injected engines run very high compression ratios with very low octane requirements. If knock does occur, there's a knock sensor to pull some timing out, to prevent it from re-occurring and doing any damage. I doubt that these engines are getting very much knock, if any. I'd run 87 in it, if it were mine. I think that you wouldn't notice much gain, if any, from premium. If I were racing it, I might try some higher octane, just to see if there was any measurable gains, but for everyday use, I'd run 87.

Worry less about the octane rating and more about the condition of the tanks where you fuel up. Slow fill means clogged filters and dirty gas. We have a Chevron here that has such old tanks they only cab fill the top 1/2 and have pulled up the intake to take from the top.

There's more to it than "this compression ratio requires this octane fuel." That only works when you are talking about a typical pushrod V8 engine with flat top pistons and wedge shaped chambers. Other factors include cylinder head/piston design and material used, bore size, altitude, engine temperature, engine tolerances (specifically piston to cylinder wall clearance), vehicle weight, and gearing. As far as fuel additives they are all worthless no matter what vehicle you have, at best they boost your octane. If your fuel system gets gummed up no magic in a bottle will fix that. Fuel injection can sit for years and fire right back up like it was yesterday.

This^ I have been driving my V6 as daily driver, drag racing, weekend fun for long enough to have decided for myself. I could tell from the first tank of 93 top tier Shell gasoline, my baby was running much better. I never looked back. It is not worth the few cents I'd save to have my permagrin maker not run at max permagrin capacity. If cost is that much of an issue, fine, run the 87, no biggie. But for me.................once you go 93 you never go back.

Highest octane for me, but mine is not a DD.
