Save Money On Gas!
Wow, what a subject! Like our last post on how to save money on groceries, there are hundreds of ways to accomplish the objective of reducing your grocery bill.

The same question holds true with, “How can I save money on gas?”
We’re sure you’ve read other blogs and articles; heard tips on TV; spoke with your neighbor, friend or buddy who’s a mechanic about things you can do to save money on gas.
Obviously, we have NO control over gas prices. They sure have spiked in the past month and, at least in the Milwaukee, WI area, seem to be leveling off and coming down a bit.
We do, however, have control over our habits. While some of the tips you’ve read about, seen or heard may appear to be redundant, they’re worth looking over. REMEMBER, the goal here at Save Money, Save Money is that we make concerted efforts to save money where we spend money AND save the money you save on your spending.
Unlike our post on save money on groceries, your efforts to save money on gas involve a conscious awareness of our driving habits. Here’s the contrast:
1. To save money on groceries, we are focused on the single task of grocery shopping. We can take time to look at prices and compare products. We can take pause, scan, put a finger to our chin, weigh our buying options, decide, pick-up the item, read the label, and finally, put the best item in the shopping cart.
2. Driving styles are the result of habit! If you live in a metropolitan area, for example, you’ve got a lot of other drivers around you and guess what? You have no control over how they drive! We have to be defensive. If you’re driving on the freeways in some metropolitan areas, you have to “keep-up with traffic” at the risk of becoming a victim of some “road-rage idiot”. If traffic is moving at 70MPH and you choose to drive 55MPH, you’re going to get honking horns, people riding on your rear bumper, giving you the “finger”, cursing at you, or having a gun pointed at you! The point is the driving part of this subject involves habits, split-second decision making and maneuvers, and no control over those with whom you share the roadway.
Save Money On Gas – 2 Major Factors: FRICTION and RESISTANCE.

Keep these 2 things in mind as you read our tips and comments on how to save money on gas. You’ll see exactly what we’re talking about.
So, we’re all smart people – relatively speaking (snicker, snicker). What do you do? You drive in a way that is practical and you exercise good driving habits regularly and with precision. For example, we live in a metro area; traffic can be horrendous both on the freeways and city streets. To drive to the freeway, we must drive a popular and busy city street to gain access to the freeway on-ramp. This street has 7 traffic signals on the 2 mile stretch of road we drive to reach the freeway. It kills us to watch people stomp on the accelerator after the light turns green only to slam on the brakes 4 blocks further to stop at the next light (Friction). It’s like watching an over-caffeinated drag racer. We don’t get it! I think that this lack of common sense is why people complain that they cannot save money on gas. Why not gradually accelerate (reduce resistance) and if you know the lights turn red (which they do on this road – hit one red, you’ll hit them all red), coast after you reach the posted speed limit.
So, to save money on gas, SLOW DOWN! Air resistance goes up as the square of velocity. The power needed and gas consumed to overcome air resistance increases as the cube of the velocity. Rolling resistance is the dominant force below about 40 mph. Above that, every mph costs you mileage. Go as slow as traffic and your schedule will allow. Drive under 60-65 since air resistance grows exponentially more dense, in the aerodynamic sense, the faster we drive. The most efficient speed is your vehicle’s minimum speed in its highest gear, since this provides the best “speed per RPM” ratio. This is usually about 45 to 55 miles per hour. Every MPH faster yields you less fuel economy. Driving 10MPH is a big difference over 5MPH; it’s twice as fast, but, there is very little difference between 55MPH and 60MPH, unless you are on a very long trip. Many people mindlessly speed wherever drive, and gain absolutely nothing but a heftier fuel bill. Assuming everything goes perfectly (and when does that happen?) going 5MPH, even 15MPH faster on a highway for a short distance will yield nothing but aggravation as you keep catching up to slower traffic. It’s virtually impossible to save money on gas. When practical simply slow down and reduce fuel consumption 10% to 20%! Changing habits will save money on gas!
Do You Have A GPS? Save Money On Gas And Use It!

We have a Garmin “NUVI” GPS. I received it as a birthday gift 3 years ago. I thought, “What the heck do I need this for? I know where I’m going!” I thought it a waste of money – it was something that I would never buy for the two of us. I was wrong! Using a GPS navigation system, generally, allows you the opportunity to select a “driving mode”. The driving modes on the Garmin Nuvi are: Fastest Route (least amount of time), Less Fuel Route, Shortest Distance Route, and Off-Road. Obviously in these times, we use the “Less Fuel” Option. Doing our own testing over several tanks of gas, we save almost 3 gallons of gasoline per tankful using the “Less Fuel” option. The less fuel route per tank of gasoline increased our travel time (in total) an average of 18 minutes. Based on a price of $4.00/gallon, the save money on gas result with our van is a savings of $12.00. The extra 18 minutes of travel time was worth $12.00 in savings.
What do we do with the $12.00? We save money by putting $12.00 into our savings account. That’s $600/year saved! When we save money on gas, we’re able to save the money we save.
Let’s take the GPS thing one step further. The Garmin NUVI also has an “Eco Challenge” setting. Somehow the darn thing measures your acceleration and braking. We select where we want to go and, then, select, the Eco Challenge. After we arrive at the destination, we can look at our “score”. The higher the score, the more we save money on gas.
Save Money On Gas With Simple Vehicle Maintenance
When driving a vehicle, the worse enemy for fuel consumption is FRICTION. This includes tire friction, engine component friction, brakes, aerodynamics and a host of others. Our driving habits, specifically acceleration and braking habits is huge in terms of how much fuel your vehicle consumes. Change your driving habits – save money on gas!
Maintenance habits have an enormous impact on fuel consumption and your ability to save money on gas. If you are driving a newly purchased vehicle, your dealership, usually, keeps a great record of vehicle(s)’ maintenance schedule. Their Service Department and Service Advisors routinely mail, email or phone you with notifications that your vehicle is due for maintenance. If you lease a vehicle, we believe that in many cases, you are required to adhere to a strict maintenance schedule. If you’re like us, we own our vehicles and we alone are responsible for keeping track of maintenance.
So there’s scheduled maintenance. What are simple things you can do before the typical and routine maintenance?

Check air tire pressure! We know, we know . . . it’s like we’re going to do this every day, right? Well, take a look at your tires every day, BUT, check the actual tire pressure once a week to ensure you save money on gas. You gas consumption is affected up to 3.3 percent for every 1 p.s.i. drop in tire pressure on all 4 tires. So when you’re off work, or washing your vehicle, be sure to take the 2 minutes it takes to check your tire pressure. If you have an air compressor at home, or a small emergency travel compressor, there should be no excuse. We know that the number of gas stations that provides free air is dwindling, but keep your tires’ pressure at or a few pounds above the vehicle’s recommendation. Not doing this will increase gas consumption and result in premature tire wear. If you find that you need to add air weekly, you may have a slow leak around the rim or valve stem.
Save Money On Gas – Drive Less When Possible
Carpool! I remember the days when we’d carpool to work. We recognize that this is a different time and schedules are all over the calendar, BUT, you cut your fuel usage “to-and-from” work by at least one-half. That can translate into you being able to save money on gas big time! Remember, to save the money you save! If you’re saving $10, $20, or more a week carpooling, save money by sticking that savings into a savings account. Your Save Money estimate is $400 to $1000/year just from carpooling!
Take the 1st available parking spot at the shopping center. Don’t spend 3-4 minutes driving through the parking lot looking for the spot closest to the door. Unless you are handicapped or injured, most of us can use the exercise – that alone is worth the extra minute it takes to walk to the door from further away.
Save Money On Gas – Shop Within Reason For Cheap Gas
Find cheap gas in your area within reason. Don’t go driving 5 miles out-of-your way to save a penny on a gallon of gas. If you have a Smartphone, you can download the GasBuddy app from the iTunes and Android Stores to get a snapshot of cheap gas in your area. If you live in a metropolitan area, one or more of the local TV stations have cheap gas listings on their station’s website. The same holds true with local radio stations posting cheap gas listings on their stations’ website.
Fill-up in the morning, especially if you live in warm weather areas. A common tip is to buy gasoline in the morning, when the air is cool, rather than in the heat of the day. The theory is that the cooler gasoline will be denser, so you will get more for your money. But the temperature of the gasoline coming out of the fuel nozzle changes very little, if at all, during any 24-hour stretch. The point for filling up in the morning is not the gas coming from the pump; it’s the evaporative vapors of gas in your vehicle’s gas tank. Mornings, generally, are cooler than other points in the day. Chances are that you are displacing less evaporative vapors in your vehicle’s tank in the morning because the tank and your vehicle are cooler. Also, fill the tank the tank full. Adding $10 of gas here or there will be wasted each time you travel to the station and wait for a pump. Instead, do it all at once to save money and save time.

Is your fuel tank half-full? Fill it up! If you live in a cold weather area (like we do in Milwaukee, WI), you run an increased risk of fuel tank and system condensation. There are varying thoughts on this subject, but allowing your tank to reach the ¼ full or less mark can shorten the life of the electric fuel pump on your vehicle. Fuel pump replacements nowadays are not cheap!
Avoid idling your vehicle for more than 90 seconds. Your vehicle gets exactly 0 mile per gallon when idling. Starting your vehicle uses as gas as letting your vehicle idle for approximately 6 seconds. Some advice: Park your vehicle and go into the bank or restaurant rather than idling your way through the drive-through. Is this a little more inconvenient than going through the drive-thru? Probably, but we believe we’ve gotten soft with all these “conveniences” and there’s a cost to convenience. You’re not reading this blog post unless your wallet and savings are also “soft”. So, what may seem like a trade-off of time for nickels and dimes is, in reality, a trade-off of time for a potential of thousands of dollars.
Use your vehicle’s cruise control if you can. Maintaining a constant speed will save money on gas. Logically, maintaining a steady speed, especially on freeways, keeps traffic (theoretically) moving at a constant speed. Everyone could, then, save money on gas.

Change your oil as recommended! Use the recommended viscosity of oil! Dirty oil increases friction in the internal engine components and affects the wear of all moving parts within the lubrication system. Again, the more friction, the more gas used.
When practical, turn-off the air conditioning when driving short trips. If your climate allows, keep the windows closed and use your vehicle’s ventilation system. If necessary, open the windows instead of using the AC. This really is practical only for city driving and short trips. The air conditioning compressor requires a lot of energy. The stopping and starting we experience in city driving really puts a load on the energy needed to power the AC compressor. You will use more gas using your AC while driving short distances or driving on city streets. For distance driving, the air conditioner is more efficient than driving with the windows open. Driving at higher speeds with the windows open creates turbulence and resistance that will affect gas mileage. Your AC will run much more efficiently at higher and longer speeds. You can clearly see that there is always a trade-off.

Park in the shade when possible. Gasoline can evaporate and build a vapor pressure within your vehicles fuel and emissions system. Make sure that you have an airtight gas fill cap. Parking in the shade keeps your vehicle cooler, requiring less AC to cool off your vehicle when you are set to drive.
Let your vehicle “warm-up” if it’s not been used for a couple of hours, especially in colder climates. This allows for oil pressure to equalize itself within the entire lubrication system, thus, reducing friction. Also, cold weather can make the oil thicken or become less viscous. Your engine does not perform to its fullest economical potential until the oil returns to its proper viscosity (liquidity).
