Not sure if this was directed to me or OP, but my car idles at 0.3 GPH, "parked" in neutral, minimal engine load (even with clutch pedal down to eliminate parasitic loading through the clutch disc and tranmission input shaft). The lowest GPH I've seen fully warmed up (181F) is 0.3 GPH. From reading the other replies, another plus for the SOHC Saturns vs my DOHC... lower idle gas consumption.
I guess I do need to replace my stock 185F thermostat with a 192F to eek out an MPG or 2.
Yes replace that Tstat.
