MPG readings taken by resetting OEM segment fuel economy calculator when passing a chosen signpost after getting the vehicle up to speed & stabilized. Final reading taken at a second signpost at the end of the route. (One update of the OEM display.)
Route: 1.6 km straight and flat section of smooth road, with no other vehicles ahead in my lane; occasional vehicles in opposite direction.
No cruise control. Speed was controlled by watching RPM instead of the digital speedometer readout, because the speedo gives no indication of rising/falling speed until the next higher/lower digit is shown. RPM has higher resolution.
