Toyota 2ZZ-GE:

Fully warmed up, 2.1g/s at the MAF with electric P/S pump on, 2.0g/s with P/S off, 775rpm

Assuming a 14:1 AFR and 710g/L (that's on the lower end of what I found) for gasoline, that's 0.72L/hour.

I would expect something fairly similar for a belt driven P/S equipped car since at idle the P/S pump uses the least power.

Toyota 1ZZ-FE was around the same at 680rpm IIRC, definitely not much below 0.7L/hour if at all. The 2ZZ's low lift cam and high compression help a lot. The gal/hour reading from a Scangauge or Torque probably assumes higher density for gasoline than I just did, as I recall the MAF reading over 2g/s at idle just like the 2ZZ.
