STARTING AND OPERATING 217 • Highway Driving - reduce your speed. • Up Steep Hills - select a lower transmission gear, but try and keep the torque converter locked. • Air Conditioning - turn it off temporarily. Do Not Operate The Engine With Low Oil Pressure When the engine is at normal operating temperature, the minimum oil pressures required are: Idle 700 to 800 RPM ...10 psi (69 kPa) Full speed and load ...30 psi (207 kPa) CAUTION! If oil pressure falls to less than normal readings, shut the engine off immediately. Failure to do so could result in immediate and severe engine damage. Do Not Operate The Engine With Failed Parts Practically all failures give some warning before the parts fail. Be on the alert for changes in performance, sounds, and visual evidence that the engine requires service. Some important clues are: • engine misfiring or vibrating severely • sudden loss of power • unusual engine noises • fuel, oil or coolant leaks 5
