When I am cruising at about 2000 rpm I seem to be burning about 20 gal per hr. Does anyone with a similar setup know what they burn at 1000 rpm. I'm showing a speed at this rpm of 10 mph on a flat day. Thanks!
Fuel burn rate on 420

At cruise of 2330-40 RPM (about 85% throttle) I burn about 36-37 GPH and travel about 28-29 MPH. At 1000 RPM I believe I am burning about 10 GPH (don't run at that speed very often). Idle (600 RPM) yields a speed of about 7 MPH and burn of 3 GPH. I don't recall 2000 RPM stats.
