General information

Economical driving conserves natural resources
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 foot on the accelerator pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
(I especially love this one!)
# 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 posted speed limits.
# Avoid carrying unnecessary items (extra load) in the car.
# Maintain correct tire pressure. Check tire pressure regularly (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 also fuel consumption.
# Avoid using automatic transmission kickdown feature unless necessary.
# However, at higher driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed than with the air conditioning off and the windows open.
# Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.

Other factors that decrease gas mileage are:
# Dirty air cleaner
# Dirty engine oil and clogged oil filter
# Dragging brakes
# Incorrect front end alignment Some of the above mentioned items and others are checked at the standard Maintenance Service intervals.

NOTE: Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using "kickdown" to help improve fuel economy.

Nice to see that at least one of the auto manufactures will admit what we already know!!

That's the normal collection of generic tips found in the fuel economy section of any car's manual, any AAA or EPA brochure, etc.

yea ive seen a similar list before in my s-10 owners manual.

dunno whats so odd about the first one...its saying to drive lightly for the first few minutes to essentially let the engine and tranny and rearend to warm up before all out hard acceleration.

A lot of people I know just idle the engine for like 15 minutes which is totally retarded, especially in 75F weather!
