Fuel Saving Tips


If you've taken a physics course, you likely understand many things involved with driving. If you haven't ever taken physics, perhaps you should take a course or read a book/article on it. Physics is immensely important in regards to driving a car. Tire traction in different elements, engine providing acceleration or deceleration, all the moving parts, steering, braking, potential and kinetic energy. Our vehicles are truly amazing with all the physics they demonstrate on a daily basis. The more you know, the better off your odds of attaining the best MPG!

Furthest shopping destination first

Driving to the furthest shopping destination on your list warms the engine to its optimum operating temperature to maximize your fuel economy as you make the shorter trips on your way back home.

Skip drive-throughs

It is better for your car and your own well-being to just park the car and walk into any store offering a drive-through.

Do not coast in neutral

Modern vehicles today, even older ones, will shut off fuel injectors after a few seconds of coasting. Using the vehicle speed to rotate the engine. If you shift to neutral, fuel will be spent to keep the engine idling.

Roof Racks

Are you going on a vacation? No? Remove that roof rack and the bars. Don't need it, don't use it? Remove it. Save up to 2 L/100 by doing so. My Jetta TDI was doing 5.5 avg without and 7.5 with the roof rack. Mind you different size of boxes will change your L/100 losses.

Before Starting Your Engine, Look for Other Cars

Why start your engine, if on coming traffic keeps you pinned in your parking space? WRONG: Start engine, look for clear traffic, pull out. RIGHT: Look for clear traffic, start engine, GO! - Doug in California

Speaking of weight loss...

Check your trunk and check our backseats. Remove anything you don't need on the road or need during an emergency. Best part is, you're decluttering and clean up as well. Sometimes, you'd be surprised at what you'll find.

Chill out...

When the light turns green take it easy and just accelerate nice and slow. You're not in a race with anyone if you gun it, it burns through gas way faster normal.. You don't have to be the first person on the line. This helps me save gas all the time, & if you apply this to your driving habits it will save your gas too! Hope this helps..

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 :)

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

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.

Changing Engine Oil Regularly

Don't forget to change the engine oil! A cleaner and high quality engine oil can lead to higher MPGs and to help a vehicle last longer!

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
