5 Ways to Ruin Your Gas Mileage

The rising cost of gas has hit everyone hard, no matter what type of car, truck, SUV or van you drive. It costs a considerable amount to fill up your tank today, and if you’re doing the wrong things with your car, it can seem like your entire paycheck is going into the gas tank. There are some things that will actually cause your gas mileage to sink very low, and it’s important that you avoid doing things that actually increase fuel consumption. Here are five things that you need to avoid doing if you want to save money at the gas pump.

1. Not Changing Your Air Filter
Most of us don’t give much thought to the air filter in our vehicle. It’s just…there. However, if you’re waiting too long to change it, you could be paying for it in increased fuel consumption. Why is this? In order to burn fuel, your engine has to have a supply of fresh oxygen. Without oxygen, fuel doesn’t combust. Your engine pulls in air through the breather and air filter. Over time, that filter will become clogged and blocked with dirt and debris, reducing the amount of air getting to the engine and, thus, making it struggle to ignite fuel correctly.

2. Low Tire Pressure
You might not think it to look at them, but your tires are designed to hold a specific amount of air pressure. If you’ve been “eyeballing” them to see if they look low, but not actually checking them with a tire pressure gauge, you could have a hidden source of additional fuel consumption. Low tire pressure means that your tires are softer, and your engine has to work harder to turn the wheels, further increasing the amount of gasoline required to move the vehicle down the road. Set your tire pressure according to the door placard and check it regularly.

3. Excessive Idling
Sometimes, you have no choice but to let your engine idle (when you’re stuck in traffic, for instance). However, there are other times when we choose to leave the engine running even though the car isn’t going anywhere. For instance, if you pull up to a convenience store and leave your engine running because you’ll “be right back”, all you’re doing is wasting gas. If you warm up the engine in the morning for more than about a minute, you’re just wasting gas. Essentially, you’re burning fuel without actually moving, which is reducing your fuel economy.

4. Driving the Wrong Way
You don’t need to have the nickname of “Lead Foot” to be guilty of driving aggressively. If you’re punching the gas, you’re doing nothing but killing your gas mileage. The two most important things to stop doing are punching the gas hard off a start and braking hard. Accelerate more slowly and you’ll see your gas mileage improve. Start braking well before you get to the stop sign or red light and you’ll see the same benefits. Finally, try to avoid speeding – driving over about 65 MPH has a very serious penalty when it comes to how much gas you use.

5. You’re Loaded Down
How much extra weight are you carrying in your car? Is your trunk full of unnecessary things? How much extraneous stuff are you hauling around in the back seat? Interestingly, the more weight you haul in your car, the worse your fuel economy will be. Essentially, every hundred pounds of weight your car pulls drops your fuel economy by up to 2%. That can add up very quickly, as it can be difficult to assess just how much unnecessary weight is in your car.

The Importance of Choosing the Correct Engine Oil

Don't Copy From This Blog...

Guest Article by Don Elfrink*

Engine oil comes in a bewildering array of weights, brands and types. A quick glance at the shelves in your local auto parts store will show you everything from 5W30 to full synthetic formulations to 20W50 and more. Which is the right oil for your car? It can be tempting to buy oil based on the recommendation of friends or family, or even to use whatever weight you’ve been using for years in your previous cars. However, this is the wrong approach to take. It’s important that you choose the right oil for your vehicle.

The Problem

The problem here is that your engine is designed to work with a specific weight oil. For instance, many newer engines are designed to run 5W20 or 5W30 – this is a lighter weight, thinner oil. Using something heavier than this can cause problems. If you have been mentally conditioned by years of using heavier oil in an older car because of leaks or “just because”, this can be a hard habit to break.

Understanding Oil Weight

Part of the issue in choosing the correct oil is understanding what all those weight ratings really mean. For those who have no real experience in the automotive industry, it can seem like a string of meaningless letters and numbers. It’s not that difficult to understand, though. The key is to realize that today’s oil formulations have a dualistic nature. They’re designed to operate differently in different temperatures. Older oil formulations are denoted by “SAE” and are often referred to as “straight weight”. That means they operate like a single weight oil, regardless of what the temperature is.

Today’s oils are made to work differently in winter and summer driving. That’s what the W stands for in the oil weight – winter. So, an oil with a weight of 10W30 would operate like 10-weight oil during the winter and 30-weight oil during the summer. That’s important to understand, because you need thinner oil during cold periods and thicker oil during the heat of summer. In the past, you actually had to change oil weights seasonally. That’s no longer the case.

How to Tell Your Type

When it comes to choosing the type of oil you use in your car, your choice shouldn’t be random. The best option is to use what the manufacturer recommends. Most modern vehicles have this shown on the oil filler cap. If it’s not there, you might check the owner’s manual. Failing that, you can contact a dealer that specializes in your brand and find out what they recommend for your make and model. If you have an older car, or the oil filler cap has been replaced, you should contact a dealer and find out what the automaker recommends for your engine.

The Problems of Using the Wrong Oil

Keeping your engine oil clean and changed regularly is important, but it’s just as important that you have the right oil in the engine. Many different problems can develop from using the incorrect oil for the application. For instance, if your car is rated for a 5W20 blend and you choose to use 10W30, you’re putting much thicker oil in the engine than it was designed to use. The first thing that will happen is you’ll see more sluggish engine performance. You’ll also noticed decreased fuel economy. If there’s a significant disparity between what you’re using and what the engine was designed to use, you might even find that the oil doesn’t lubricate quite as well.

Always use the oil that your engine was designed for. If you’re going with a thicker oil because of leaks, it’s better to repair them and replace leaking gaskets than run oil that is too heavy for your car.

7 Useful Tips to Prepare Your Car for Cooler Weather

Guest Article by Don Elfrink*

It’s that time of year again. The leaves are changing colors and the weather is cooling down. While you’re no doubt happy to see the heat of summer on the way out, cool weather presents some serious challenges for your automobile. You need to make sure that your car is prepared to handle the onset of cold weather so you are able to stay safe and sound on the road this winter.

1. Start Now

You might think that cool weather maintenance doesn’t need to be done until the onset of winter. However, fall is actually the perfect time to get a jump on things. Waiting until the weather goes from cool to cold can be a recipe for disaster, so don’t wait. Do it now.

2. Antifreeze

One of the first things you’ll need to check is your vehicle’s antifreeze. During the summer, your engine coolant keeps the engine within the normal operating temperature range. During cold weather, it does the same job, but it also keeps the coolant from freezing. Regular water (or weak antifreeze/water mixes) will freeze with low temperatures, creating serious problems for drivers. Blown radiator hoses are only the mildest threat here. Make sure you check your antifreeze level, as well as its freeze protection. If it’s been several years since it was changed, consider doing a full drain and fill.

3. Gauge Your Tires

While summertime brings thunderstorms and heavy rains that you’ll have to drive through, cold weather brings ice and snow. You’ll want to make sure that your tires are able to handle those threats. Check the tread on your tires (you can pick up a tire gauge at pretty much any auto parts store). If the tread is low, consider replacing your tires now, before they have to face the prospect of winter driving conditions. You might also consider looking into studded snow tires now if you live in an area where heavy snowfall is an issue.

4. Look at the Battery

Cold weather kills batteries. Heat during the summertime can definitely take its toll here, but the onset of winter sees the highest number of dead batteries. Don’t become a statistic – make sure that your car’s battery is fresh and up to the challenge. You should have a full charging system test performed as well to make sure your starter and alternator are in good shape.

5. Check the Wipers

We tend not to think about our windshield wipers until they’re needed, but that can be too late, especially during the colder months of the year. Make sure you have new wiper blades installed before the temperatures drop too low. You might even consider purchasing blades made especially for wintry conditions.

6. HVAC

You’ve been running your AC all summer, but now it’s time to crank up the heater. Make sure your heater works well before cold weather arrives. A heater that doesn’t do its job could be suffering from any number of problems, from a faulty heater core to a dying thermostat – all easy enough to rectify if caught in time, but real hassles if you let them wait.

7. Winter Prep Is Important

While it the cool, comfortable days might be a nice change from the heat of summer, don’t let yourself be fooled. Cold weather can arrive with no warning, and being caught unprepared is a bad thing. Make sure you have your vehicle prepped for the arrival of winter – if you are unsure exactly what to check, use a reputable mechanic and have them conduct a full inspection for any issues pertaining to winterizing your vehicle.

Keep Your Car Looking Great by Detailing It

Guest Article by Don Elfrink*

The appearance of your car has a huge impact on how much you enjoy it and how long you keep it. If your vehicle looks rundown and old, chances are good that you’re not going to enjoy driving it that much, even if it’s mechanically sound. However, you can keep your car looking great for years and years to come by taking the right steps. One of those steps is to have it detailed periodically. While you can certainly take care of basic cleaning on your own, a good detailing service can offer some significant benefits.

What Is Detailing?

Auto detailing is pretty much exactly what it sounds like. You take your vehicle to a professional detailing service and they go over it thoroughly, cleaning and polishing, buffing and shining it until it looks great. A good detailing service can offer a lot of benefits, even going beyond just giving you a good looking vehicle to drive. Protecting your vehicle’s interior and exterior will keep it looking great for years, but it will also help improve the value of your car immensely, as well as protecting the interior and exterior from the damaging elements.

What Should a Detailing Include?

Most detail shops offer several different levels of service – you’ll find them listed on their service menu. The majority offer a basic level cleaning, a mid-range option and a full-service cleaning. That lets you choose the option that best fits your needs and budget. However, you’ll find that going the full-service route is often the best choice. It can:

• Save you time and hassle
• Protect the interior and exterior of your vehicle
• Prevent damage from sunshine and acid rain, as well as dirt and grime
• Hide minor scratches and scuffs

What Services Should a Good Detailing Include?

Of course, you’ll need to know what services should be included in a quality detailing. The actual options you have available to you will vary considerably depending on the company you choose, but the most common options can be found below:

• Engine Bay – Not all detailing companies offer this, but cleaning the engine bay can help keep dust, oil and grease from building up. It can also help you spot leaks more easily.

• Washing – A full washing of the vehicle’s exterior should be performed. The service should use a microfiber cloth and a specialty car wash formulated for automotive paint rather than any other type of cleaner.

• Waxing/Polishing – The detail service should offer both waxing and polishing service. Waxing and polishing in conjunction will help remove imperfections, hide blemishes and protect against further damage from the elements (including oxidation and etching from acid rain).

• Interior – The interior of your vehicle should be thoroughly cleaned (from the seats down to the floor mats). A protectant should be applied to all vinyl and leather components (including the dashboard, console and door trim).

• Wheels – Proper wheel care is important, and a good detailing service will use the right cleaner and protectant for the type of wheels you have (steel, aluminum, etc.).

What to Expect in Costs

Auto detailing isn’t “cheap”, but it doesn’t have to cost an arm and a leg, either. A full service on a car in good shape might run you about $150, but that will vary with different factors, including where you live, the condition of your car and the extent of the service that you choose. Rather than choosing based on price, it might be a better idea to choose a detailer based on the reputation, the services offered and the results they can provide for their clients.
