Tips on saving fuel
Drive At an Economical Speed ::.
A vehicle’s air resistance increases four times when the
vehicle speed is doubled, and nine times when the vehicle
speed is tripled. Drive a vehicle at a moderate speed. Keep
your speed under 80 km/h for efficient fuel consumption.
Shift Up Earlier & Shift down Slightly Later ::.
For the best fuel economy, the highest gear you can use is
the most economical. Shift from low to high gear as soon as
The following provides suggested vehicle speeds for shifting
into a higher gear. These suggestions relate to fuel economy
and vehicle performance.
Is Wasteful ::.
Eliminating unnecessary acceleration. Rapid acceleration
uses as much as 50% more fuel. Increase speed gradually to
avoid burning-up of unnecessary fuel.
Minimum Idling ::.
Stop useless idling. If you stop for more than 5 minutes,
turn off the engine.
Use Your Air Conditioner with Moderation ::.
Remember that the engine drives the air-conditioner
compressor. Use it only when necessary, and improve your
Reconsider Your Route ::.
The best route is the shortest one, but consider the type of
roads, too. Short runs and stop-and-go driving consumes more
MAINTENANCE ENSURES GOOD FUEL ECONOMY
Is the Air Pressure of the Tires Appropriate?
When the air pressure is low, rolling resistance increases,
worsening the fuel economy. Note that the rolling resistance
of radial tires is smaller than that of bias tires.
Is the Coolant Temperature Appropriate?
The engine wears out more quickly and the fuel consumption
becomes worse, when the coolant temperature of the cooling
water is too low.
Are the Fuel Injection timing & the Valve Clearance
If the fuel injection timing is slightly delayed and the
valve clearance is larger than the specified, the engine
power decreases and the fuel economy worsens. As they are
periodical checking items, ensure they are checked without
Isn’t the Air Filter Element Clogged?
If the air filter element is clogged, the engine power
decreases and the fuel economy worsens because of the
reduction in intake airflow.
Is the Engine Oil/Fuel Grade Appropriate?
Use recommended oil/fuel grade only. This can increase
engine protection & improve performance.
Do You Experience Clutch Slippage & Brake Drag?
Clutch slippage reduces engine power transmitted,
worsening the fuel economy. In addition, brake drag quickly
wears out the brake lining, leading to waste of fuel.
