The article says,

Infiniti claims VC-T is capable of providing any desired compression ratio between 8:1 and 14:1. Bumping the ratio to 14:1 during light-throttle cruising maximizes fuel efficiency. Then, when the driver dips into the throttle, the compression ratio can drop as turbo boost rises, avoiding detonation.

Honestly don't know. It seems to be they're suggesting that the 14:1 regime is during light-throttle cruising, so perhaps regular gasoline suffices.

Most stations carry it. It's labeled "diesel"
