pg. 4:3 Driving economy, Carbon deposits
Economical driving does not necessarily mean driving slowly
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and
adjusting the speed of your vehicle to immediate traffic conditions. Observe the following rules:
●
Bring the engine to normal operating temperature as soon as possible by driving with a light forot on
the accelerator pedal for the first minutes of operation. A cold engine uses more fuel and is subject to
increased wear.
●
Whenever possible, avoid using the car for driving short distances. This does not allow the engine to
reach normal operating temperature.
●
Drive carefully and avoid rapid acceleration and hard braking.
●
Do not exceed speed limit.
●
Avoid carrying unnecessary items (extra load) in the car.
●
Check tire pressure regularly (check when tires are cold).
●
Remove snow tires when threat of snow or ice has ended.
●
Note that roof racks, ski racks, etc., increase air resistance and thereby fuel consumption.
●
Turbo: try to keep the boost pressure gauge in the black range.
●
Utilize overdrive at speeds above approx. 45 mph (70 km/h)
●
Avoid using automatic transmission kick-down feature unless necessary.
Other factors which decrease gas mileage are:
●
Worn or dirty spark plugs
●
Incorrect spark plug gap
●
Dirty air cleaner
●
Incorrect valve clearance
●
Dirty engine oil and clogged oil filter
●
Dragging brakes
●
Incorrect front end alignment
●
Low tire pressure
