Warmed up and idling at 850rpm my 1.8L gasser (B18B1 from a 90's Integra LS/DA) uses about 0.36GPH, but when the car is rolling my idle roams between 850 and ~1400rpm, so I end up with an average rolling idle consumption somewhere around 0.45, give or take a few hundredths.

Roaming rolling idle seems like it's not an uncommon problem in Hondas, I wonder if it's due to alternator load or something? I have the coolant lines disconnected from my IACV, I thought they were only to prevent seizing in sub-freezing weather, but maybe I'll try reconnecting them.
