8 Ways to Increase Gas Mileage - for Free!

by Robert, Cars for Keeps Mechanic

Want to save some money by getting better gas mileage? Sounds great right? What about being able to do it all for free?

There are many things you can do to increase your fuel economy, with little or not out-of-pocket expense. It's true that tune-ups and routine maintenance are great for your vehicle. They insure that your "machine" is properly oiled and functioning to its originally designed specifications. However, as you know, spark plugs and oil changes are NOT free. So what else can you do?

1. Drive sensibly. Aggressive driving, (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by 33% at highway speeds and by 5% around town. Sensible driving is also safer for you and others, so you may save more than gas money. That means saving up to 13-18 cents per gallon!

2. Observe the posted speed limits. While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 60 mph. You can assume that each 5 mph you drive over 60 mph is like paying an additional $0.24 per gallon for gas. That equals 19-61 cents per gallon, enough to reconsider speeding.

3. Remove excess weight. Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds in your vehicle could reduce your MPG by up to 2 percent. The reduction is based on the percentage of extra weight relative to the vehicle's weight and affects smaller vehicles more than larger ones. So before leaving the house again, think: do you really need those dusty encyclopedias sitting in the trunk? This could add 3-5 cents per gallon.

4. Avoid excessive idling. Idling gets 0 miles per gallon, period. Cars with larger engines typically waste more gas at idle than cars with smaller engines. Turn the engine off if you will be waiting for more than 60 seconds, whether you're waiting for a friend, at a drive-thru bank or fast food restaurant. Idling your car for an average of 20 minutes per day could equal up to 50 hours of idling each year.

5. Use cruise control. Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.

6. Use overdrive gears. When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces engine wear.

7. Maintain proper tire pressure by checking them at least once a month. Tires that are low on air create more rolling resistance which in turn decreases fuel economy.

8. Tune-ups, oil changes, fluid flushes. Ok these are not free but you can improve fuel economy 5-30% by having your car properly tuned. Stop by Cars for Keeps and see what it will take to ensure an efficient automobile!

Until next time!

Snow Tire FAQs: Michigan Winter Driving Essentials

by Marjorie, Cars for Keeps Social Media Manager

If you've lived in Michigan your entire life, like me, you understand how easy it is to become helpless to the winter elements. If you're new to the area, then you're in for a treat; Michigan's legendary lake effect snow is beautiful, unpredictable and an absolute horror for unprepared winter travelers. While there's not much we can do about keeping our cars from being buried in snow drifts or coated in ice every morning, we can do something about making sure our cars remain on the road - once we've managed to get there.

Here are a few basic facts you should know about snow tires. Check out the YouTube video at the end of this post if you don't believe tread really makes a difference. Which car will you be?

Aren't all-weather tires good enough for winter?

No. Again, I refer you to the video in this post for proof. All-weather tires are designed for dry and wet conditions in warm weather, but they're in no way prepared to give tread on black ice, packed snow and sandy slush. Snow tires are specially made with softer rubber and carefully placed grooves which quickly wear down on dry pavement - which is why you should never leave your snow tires on past spring...unless you like buying new snow tires every year.

When should I put on my snow tires?

Well, how brave are you? If you're a daredevil like me, you may intentionally wait until after the first snowfall just to test your ice-racing skills. For the rest of you, who value your and your family's safety above thrill, it's best to have snow tires put on before the first snowfall, which, in Michigan, could be anytime between October 15th and December 30th. Typically, having snow tires put on a few weeks before Thanksgiving is plenty early enough, and it ensures safe holiday travel.

Should I get studded tires?

This question is best directed to your tire dealer or auto repair shop (I'm sure Dennis has a strong opinion), but there aren't very many situations where studded tires help you more than regular snow tires - in some environments, studded tires can actually give you less traction. Studs are only good for packed snow and ice, and they will hinder traction in thick snow, slush and dry pavement. So unless you're commuting across the tundra in Alaska, sticking to unstudded snow tires is a safe bet.

Should I get two snow tires or four?

Tire dealers and some mechanics have a strong opinion on this question, too. But for those of us who would prefer not to spend an extra $250 on two superfluous snow tires, here are the bare facts: front wheel drive cars should at least have both front wheels equipped with snow tires, and likewise, rear wheel drive cars should at least have snow tires on both rear wheels. All wheel drive automobiles, of course, should have four snow tires. It's true that having snow tires on all four wheels, even on front and rear wheel drive cars, provides ideal traction, but having only powered wheels fitted with snow tires will still provide far more traction than regular summer or all-weather tires.

For rear wheel drive owners, remember to throw some weight in the back. Keeping your summer tires or some bricks in the trunk - or bed - will give you an extra boost in traction.

Safe driving!

Automatic Transmission Failure: How to Check Fluid and Prevent Costly Breakdowns

by Marjorie, Social Media Marketing Manager for Cars for Keeps

No two words strike fear into the hearts of those of us who are not mechanically inclined like the words: transmission failure.

Checking my engine oil may be the extent of my automotive expertise, but I've learned that having a faulty automatic transmission can mean almost certain death for a vehicle. For most cars, particularly those that are getting on in life, the cost of replacing an automatic transmission exceeds the value of the entire vehicle - rather like totaling your car.

Fortunately, transmission failure does not happen randomly; indeed, catching the early signs of transmission trouble is easy if you know what to look for. Here are a few things you can do to make sure your automatic transmission doesn't cause premature car death.

1) Own cars with manual transmissions. Ok, so this isn't exactly a solution to maintaining an automatic transmission, but car owners should be aware of the differences between manual (standard) and automatic transmissions. Manual transmissions (or "stick shifts") are more energy efficient than automatics, but more importantly, they have far fewer moving parts - which means way less maintenance and risk of part failure. Sure, you can talk on your cell phone, keep the kids in the backseat from fighting and drink your coffee simultaneously while driving an automatic, but a manual transmission will never conk out like an automatic.

2) Check automatic transmission fluid (ATF) regularly. This is really not hard - no harder than checking your oil levels. If you're unsure exactly which dipstick is for the ATF or what to look for once you find it, watch this short video on how to check your car's ATF. If you're still unsure, there's a great little auto repair shop on Fulton Street where the mechanics would be happy to show you.

Keep in mind, you're looking for two things: level and color. The fluid mark needs to hit between the low and high marks, and it should be nice and red.

3) Change your ATF regularly! Although it may seem like this step would naturally follow the previous step, there are those of us (like me) who need the reminder. If your transmission fluid is dark, brown or muddy-colored, it's time for a professional to take a peek and probably perform a transmission fluid flush.

Please think twice before taking your car to a drive-through service for transmission fluid flushes. There are many reasons why these places don't always offer the best service for your money, but a certified AAA repair shop like Cars for Keeps will certainly give you a more thorough flush and overall checkup.

4) Listen to your car. As we've said here before, your car will usually tell you something is wrong before a major breakdown. Any out of the ordinary noises could be suspect, so bring your car in for inspection if you hear anything unusual. J.B. Herbert gives us a few pointers here:

Top 4 Reasons to Change the Oil in Your Car (Featuring Red Green)

by Marjorie, Cars for Keeps Social Media Marketing Consultant

Remember the Red Green Show? If Michigan's rednecks, bumpkins and "yoopers" had an icon (other than Ted Nugent), it would be Red, handyman extrodinaire.

Since Cars for Keeps is giving away a free oil change this month, today we'll focus on a few reasons why oil changes are important to your vehicle's health. Red Green will demonstrate a few of the many things NOT to do to keep your vehicle running.

Changing your oil at home to save money is a nice idea, but as Red so charmingly demonstrates, oil changes gone wrong can easily lead to far bigger expenses. Like Red says:

"If you get it done at a gas station or wherever, you're just not sure if they've done a bad job, where if you do it at home, you know."

We hate to gainsay Red Green, but you can be sure that an oil change performed by Cars for Keeps is done right.

To make sure I had my facts straight, I called our mechanics at the shop and had them list for me a few of the grittily-detailed benefits of regular oil changes. They listed the top 4 ways regular oil changes can prevent mechanical failure and increase your car's performance.

Regular oil changes:

1) Remove contaminants like dirt and metal shavings from the engine, removing risk of failure or part wearing

2) Prolong engine life by reducing friction and heat

3) Keep the engine cool which, if you remember my overheated engine confession from last Wednesday, is very important

4) Keep your car running efficiently. Old oil can bog down your vehicle's mileage.

Consult your owners manual to see how often the oil in your vehicle should be changed. If it's been more than a year, you can just assume it's time to change your oil now.

How to Prevent Cold-Weather Stalls: Winterizing your Battery

by Mike, Cars for Keeps Mechanic

Hunting season is fast approaching, and that means it is time to at least start THINKING about winterizing your vehicle. Have you ever jumped inside your car to head to work in the morning to find your car will not start? It's happened to the best of us, but there are a few simple things you can do to help prevent this scenario from happening to you this winter.

Something to keep in mind is that our car's battery loses about a third of its starting power when the temps dip down into the 30's. In addition, our driving habits in the winter make it less likely the alternator will be able to fully recharge our car battery as we drive. For example, we tend to drive less often and we drive shorter distances in the winter, we constantly run the defrost and we are using our headlights more than in the warmer months - all putting a larger load on the alternator.

So what can you do?

1) Take a Peek Under the Hood: Have your battery checked before winter hits to make sure your terminals are tight and your battery is not corroded. (Stop in at Cars For Keeps & We'll do it FREE!)

2) Turn "Stuff" Off: Turn off your blowers and accessories when you turn off your car so there isn't as large of a load on your battery when you go to start your vehicle again. Turn your headlights on after you start your vehicle, NOT before.

3) Park Inside: Park your vehicle in a garage if you have one. This will help keep the battery somewhat warmer.

4) Pay Attention to Your Headlights: Do they dim and brighten on occasion? If so, stop by Cars4Keeps and one of our technicians can test your alternator for you.

5) Listen to Your Vehicle Start: Do you notice your car is having trouble turning over (starting), but once it is running everything seems normal? This may indicate that your battery has a low charge, weak connection or strater getting ready to leave you walking.

The last thing any of us need this winter is to be stranded somewhere with flakes swirling around us and a car that refuses to start. Be proactive and take winterizing your vehicle seriously this year. While there is more to it than batteries and alternators, a quick stop into Cars4Keeps is all you need to get your car in top winter condition.

See you soon,
Mike
