Fuel Saving Tips


driving in mountains and hills

When going up grade slowly press down on the accelerator while letting the speed drop maybe 5-7 mph. This will keep the transmission from shifting into a lower gear which uses more fuel. As you crest the hill let up on the gas after the speed climbs back to normal, then let the vehicle speed up 5 - 7 mph going down hill to help get up the next grade. I get 10 to 15% better mpg by following this technique driving big hills and mountains.

Headlights On? / Use Engine ON coasting to keep battery charged

During the day I practice aggressive EOC (engine off coasting). But at night with your headlights on long periods of EOC may mean parking your car with a less than fully charged car battery. If you use your car infrequently, you might return to a battery too weak to start your car. To avoid that problem, when your headlights are on, simply use an Engine ON Coasting method. - Doug in Oakland, California :)

Concern

The low gas light switches on early because it is very bad for the engine to run the tank dry, so even if the vehicle has a 20 gallon tank the light will switch on so you don't ruin your engine

Don't rush !

Remember - it's better to be 5 minutes late in this world than 35 years early in the next world

Coasting choices

Many new cars have DFCO - deceleration fuel cut-off - that completely stop the fuel flow (even in non-hybrids) when coasting in gear. This adds drag, but uses zero fuel - good for downhills or slowing. To better maintain speed, consider depressing the gas pedal about 1/2" (1 cm). This adds very slight gas usage, and is very close to coasting in neutral for gas consumption. Check it for your car using a Scangauge or similar tool.

Top Tier Fuel not what it's pumped up to be

An additive package cannot make good fuel out of dirty, low-quality crap. I know of one station that is advertised as "Top Tier" on Gas Buddy that sold diesel fuel that was so contaminated it was dark brown in color. Two of our company rigs had clogged filters soon after fuelling up at one of these stations. We haven't been back, since, and I now look at the Top Tier claims with great skepticism.

Dont Drive Farther To Save A Few Cents II

If a gas station across town in a few cents cheaper, don't go out of your way to save a few cents. You will probably burn the cents on the way there and back.

Diesel, Hybrid, Plug-in Hybrid MPG

Check out my page to see real world mileage of various fuel efficient vehicles driven over the same route. MPG is only fuel use, and does not include electricity obtained from the grid. The cost per mile is an interesting figure.

Why real-time mpg computers are beneficial

It's common knowledge that on-board fuel economy meters can be slightly optimistic, however, in my experience, they've never been off more than 5% from the real mathematically-calculated figures, often less than 3%. However, for those striving for the best fuel economy, these meters can be helpful for an entirely unrelated reason. They can help us all drive more economically. Regardless of how accurate your computer is, it will likely help train you to drive more efficiently when you have your avg mpg staring you in the face every time you get behind the wheel.

Open up intake and exhaust on older vehicles

Running a proper Cold-Air Intake or Short-Ram Intake can increase mileage by 2-3mpgs. Going to a larger diameter, better flowing exhaust system and also increase mileage. Both of these have worked very well for my pre96 vehicles. My 94 Voyager is running a SRI and averages over 25mpg, prior to the intake it averaged around 23mpg. The 95 is the same story, it used to struggle to pull over 20mpg, now its around 23 everytime.

Consider the time to leave when parking.

Going into a parking space forwards might be faster, so use less fuel, than reversing in. However, is it faster to reverse out of the space? Most of the time it's not & you'll be using more fuel as the engine will be cold(er). As a bonus you're far less likely to hit someone or something if you revers into a parking space.

Use cruise control to improve mpg

Edmunds web site's test results: Up to 14-percent savings by using cruise control, average savings of 7 percent. This is for fairly flat roads, not for mountainous areas.

re Danger of using Angel Gear

Angel Gear is neutral, a most dangerous practice going downhill to save fuel or to pick up speed from the weight of the vehicle & the incline. Save fuel maybe - cause accidents probably. With no engine braking this practice is exceptionally dangerous. Where accidents have been created with this use its usually you & I that come off second best - not the experimenter !

back into parking spots in cold weather

Not only does this give you a better & safer view when pulling out, it's easier on the transmission to go into forward drive when fluids are cold rather than spinning in reverse gear when the transmission is at it's coldest.

Hypermiling does MORE than Money at the Gas Pump!

Less aggressive acceleration reduces tire wear. Less braking reduces tire wear AND brake pads/rotors. Hypermiling also lowers stress. You'll arrive at your destination less anxious. - Doug in Oakland, CA

Leave early

Kind of a no brainer, but I've found that if I want to slow down and save fuel, it helps to start before I even leave the house. If I'm ready to walk out the door but have extra time, I can either putz around at home or go ahead an leave. Getting on the road early means I can relax and drive whatever speed I want. Luckily, most of my hour long commute to work is on a relatively quiet country road, so I can drive 45 without anyone raging at me.

Lighten your AC Load by Painting your Roof White

My 1989 Civic hatchback doesn't have air conditioning and, even though the car is light blue, the interior can still get quite hot. So I borrowed a design idea from those Mini Coopers you see with white roofs. I used Plasti Dip to paint my roof white. Because it's a rubberize paint, I can always peel it off to return the car to original. The white roof makes a VERY noticeable difference with the cabin temperature. - Doug in Oakland, CA

Drift Wide Around Corners

When turning corners, you'll scrub off LESS momentum by NOT turning so sharply. NOTE: When making a right turn, California vehicle code you're suppose to turn alongside the curb. But, when making a left turn you can make a wide turn and drift into the far lane to keep up your vehicle speed. - Doug in Oakland, CA

Smartest Driver on the Road

Drive according to the stoplights. At almost every single stoplight that turns red on approach you will notice other drivers just keep barreling up toward the light and then finally hitting the brakes hard at the end. This shows more than anything how simple minded and unintelligent humans generally are. When a light changes red you must immediately let off of the gas! If you coast slow enough you won't even have to stop (in smaller towns) and will still be rolling when the light changes green. This is how I drive, and when you start driving this way you will be the smartest driver on the road.

Check Engine Light diagnostic may become a Gas Saving Tip

Did that yellow or red Check engine light come on? Have it diagnosed right away and don't ever delay if it needs a repair to your Oxygen Sensors and Mass-air flow sensors when they go bad. It will cost you a lot of money as they reduce MPG or may damage the engine if they are not functional and kept properly adjusted.

planning your kindness at junctions?

Many drivers stop to let others out at junctions, but are they considering there fuel consumption, carbon emissions and kindness to those following them? Better to look well ahead and increase the gap between you and the vehicle ahead so the driver has time to emerge without you stopping. Do you check your mirror to see how many people behind you stop when you let one vehicle out if a junction?

Try to avoid stops

Look well ahead and avoid accelerating towards hazards and stops. Lift off early for that traffic light, queue or roundabout. Can you get there when you can go.? Imagine the "speed" film with Sandra Bullock? Your car will explode if you go slower that 5mph. !

Achieving High MPG Requires a Race Car Driver's Mentality

The best MPG tip I can offer is to reset that thing between your ears. While you and race car drivers move at opposite ends of the speedometer that's the only difference. Both think of ways to modify their vehicles to perform better. Both choose appropriate driving tactics to get around efficiently. Both use driving skills, whether it be EOC or picking the right corner line. So, consider a new tankful of gas as the "drop of the green flag" and the start of a "new race". And, pulling into a gas station is the drop of your "checkered flag". Be efficient! Doug in Oakland, CA

Neutral coasting

Coasting in neutral in most cases is more fuel efficient then leaving the transmission in gear and allowing the ECU to shut off the injectors. This is because in neutral you can coast MUCH farther than you can with the transmission in gear and engine braking. If you need to slow down then and only then should you coast in gear as the engine braking is beneficial at that time.

Park your car facing East every night

This especially helps in the winter when the sun comes up, it'll almost always melt the frost on your windshield so you won't have to scrape it. The heat will also warm up your engine bay a bit so it will aid in your fuel economy slightly by creating a warmer engine before you start it.
