Have you ever gone to Chamblee to listen to an orchestra? The musicians take the stage early and tune their instruments. Each individual instrument must be in tune, but the critical thing is for the entire orchestra to be in tune with each other. That’s why they tune up together.
Now this is no surprise; I’m going to relate the orchestra to your car. Your engine has many component systems that each need to be working properly. And the components need to be working in sync, all timed up together in order for the engine to work efficiently.
We call this, (ta-da) a tune-up. When an orchestra’s out of tune you get a bad concert. When your vehicle’s out of tune you get bad performance and bad fuel economy.
So check your owner’s manual for recommended tune-up intervals. Or ask your Chamblee service advisor at J&L Auto Service what he thinks.
…Just be careful not to say you want to make beautiful music together – that kinda makes us uncomfortable.
Your sedan requires plenty of clean fuel to run. If your fuel contains contaminants, your fuel injectors will eventually become clogged up. When this happens, your sedan engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts MPG and performance as you drive around Atlanta. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.
That’s why all vehicles, including sedans, come equipped with a fuel filter somewhere between the engine and the fuel tank. The job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and keeps them out of the fuel stream. Of course, like all filters, it will eventually get clogged up and need to be replaced at J&L Auto Service in Chamblee .
If your fuel filter is clogged, the sedan engine can’t get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your sedan engine running, but doesn’t protect it from detrimental contaminated fuel.
Chamblee drivers may find that they need to change their fuel filter at J&L Auto Service more frequently as their sedan ages. Over the years, additional sediment and detrimental rust accumulates in the fuel tank and can be drawn into the fuel system. Your fuel filter stands guard at the gates to your engine to protect expensive parts and to maintain performance and fuel efficiency.
Chamblee car owners know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine’s cylinders. This is the function of the fuel injectors.
There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.
Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.
For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower.
Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved fuel economy.
Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.
Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.
When fuel injectors get dirty, their precision drops off. The spray pattern won’t be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and gas mileage for Chamblee drivers as well as delivering less power to the engine.
Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we’re talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.
So keeping your fuel injectors clean is just good auto advice for Chamblee motorists. The best way to do this is to change your air and fuel filters regularly and practice other habits of good car care and preventive maintenance at J&L Auto Service in Chamblee. Cleaning additives in your fuel can also help.
If you do end up with gum or varnish in your fuel system, you’ll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.
Diesel engines have been used extensively in Europe and Asia for many years. They haven’t been as common in Atlanta because of the high sulfur content in our diesel fuel. But the government is now mandating lower sulfur content and, as a result, we are going to see more Chamblee auto owners driving diesel-fueled vehicles on the road, especially in passenger cars and SUV’s.
Diesels are popular in Chamblee because they get better gas mileage than gas-powered engines. They also last longer. Modern diesel engines are quiet and powerful. And if you associate diesel engines with black smoke, then you’re not up with the times. That smoke is a thing of the past.
Diesels don’t produce any more pollutants than gasoline engines. The pollution standards for diesel-powered vehicles are as strict in Georgia as for other vehicles.
Also, diesel engines can run on bio-diesel fuels as well as fossil fuels. Diesel fuel can be produced from vegetable oil or from cellulosic waste like wood chips and sawdust. In Atlanta, we may soon see bio-diesel produced from algae. These fuel sources will lessen Chamblee auto owners’ dependence on fossil fuels and may even become truly renewable and sustainable.
Diesel-powered vehicles perform as well as other passenger vehicles, also. Most Doraville people don’t notice a difference in driving one or the other. If you haul heavy loads or tow a trailer in Dunwoody, however, the diesel is a definite improvement.
So, you may be asking, if diesels are so great, why don’t all Atlanta car owners drive them? Surely there are disadvantages you haven’t told me about. That’s true. Diesel engines are heavier than gas engines, and they cost more in Georgia. The better fuel efficiency of the diesel engine is partially offset by the higher purchase price.
Because of higher fuel prices, diesel engines used to be more costly to drive in Atlanta. But now, with higher volatility in the prices of both gasoline and diesel fuel in Georgia, that cost difference is less definitive. Whether a diesel or gas engine is more expensive for Chamblee auto owners depends now on the current price of fuel in Georgia and how many miles you drive.
Consider also that diesel-powered vehicles have a high resale value in the Atlanta area, and the costs of owning and operating a diesel vs. a gas-powered vehicle in Georgia becomes a real toss-up.
Preventive auto maintenance for diesel vehicles has also become similar to that of gas-fueled vehicles in recent years. The major difference is that diesels require cleaner fuel, air and oil, so their filters are more expensive in Chamblee than those for gasoline engines. The engine air filter must be changed more frequently as well.
The costs for car care and repairs in Chamblee are similar. Wait, you may be thinking, but you just told me that filters are more costly and have to be changed more regularly. True, but that is offset by the fact that diesel engines have a much longer lifetime than gasoline engines. So if you are the type of owner who prefers to hang on to a vehicle for a long time, you will be more than rewarded with a diesel engine.
So if you have been looking for J&L Auto Service auto advice on whether to switch to a diesel vehicle or stay with a gas-powered one, then we hope this helps. The answer as to which type of vehicle is better is that it depends on the Chamblee driver and their driving habits. Now that you know the facts, you can make an informed choice based on your own priorities and needs.
There’s not much we can do about the price of gas in Chamblee Georgia, but we do quite a bit about how much we use as we’re driving on our Chamblee streets.
Our driving habits can dramatically affect our fuel economy.
The first thing we can do is watch the ‘go-pedal’. Hard acceleration just sucks the gas. Gently leave stop lights and plan lane changes so you don’t need to floor it. That can save you hundreds of dollars a year.
Go a little slower on the freeway to Atlanta. Once you’re going more than sixty-five miles an hour your fuel economy starts to drop dramatically. Leave early so you don’t need to rush to be on time. And cruise control is your friend – steady speed uses less gas.
Plan errands ahead. Make fewer trips by combining errands.
Hey at current gas prices, a lead-foot might as well be a gold foot.
If you’re a quart low in your sedan, there isn’t enough motor oil to lubricate your engine properly. The extra friction causes drag that reduces fuel economy while you’re driving around the Chamblee area.
The same goes for dirty oil; it doesn’t reduce friction properly. The result is you get to watch those numbers at your local Chamblee gas pump rolling higher and higher.
The transmission also needs the proper amount of clean fluid to do its work. When it’s in need of service, the transmission drags your fuel economy down.
So keep it clean and give yourself a fighting chance.
The team at J&L Auto Service in Chamblee and Georgia car owners are all talking MPG right now. Better gas mileage. Fewer emissions. Chamblee auto owners want to save the environment and their pocketbooks.
And we all know—or should know—that preventive maintenance will help maximize fuel efficiency. But is there something more Chamblee auto owners can do? After all, some of us Chamblee folks can’t cut back on our driving, and others would like to do more to economize.
Weight is one major enemy of fuel economy. The more you lug around in your vehicle, the more fuel you have to burn to get from Chamblee to Doraville. And that means buying more gas in Chamblee and producing more emissions.
Of course, your sedan’s weight isn’t negotiable. And you can’t do much about the weight of your passengers. And this isn’t an article about diet and exercise.
But look around your sedan. Are you hauling a bunch of unnecessary weight around Georgia? Do you really need your golf clubs every time you leave your Chamblee home? Store sports equipment in the garage. Load it when you need it and store it when you don’t. Who knows? The extra exercise just might reduce the other type of weight in your vehicle.
The same goes for anything else in your car: make-up kits, music collections, extra electronics, spare clothing; whatever your particular extras may be. Pack it when you need it; store it when you don’t.
Clean out your Chamblee. You’d be surprised how much weight you’re lugging around Chamblee in plain old junk. Toss old papers, leftover food, and regular old dirt. Even if it’s not a lot of weight, you’ll feel better when you get into your car. A good cleaning is also part of good car care.
Now, don’t toss stuff you really do need. You do need that spare tire—the one in your trunk. And a kit of emergency essentials is not a bad idea. But just carry around the day-to-day essentials. You can pack a more extensive kit and store it in your garage, then toss it in your Chamblee when you go on a longer trip, but you don’t have to lug it around all the time. After all, are you a driver? Or are you a junk chauffeur? Lose the junk and save some money in Chamblee.
Most Chamblee and North Atlanta motorists want to save on gas and seek our advice on improving fuel efficiency. At J&L Auto Service, we are frequently asked, however, if it is really worth the extra effort. Just how much money can Chamblee motorists actually save?
The US government has a website dedicated to helping us use less fuel. It presents the cost savings in a way Chamblee motorists can relate to and is relevant for all vehicles. Let me give you an example: Having your sedan engine properly tuned, can save up to 4%. If you’re paying three-fifty for a gallon of gas in Chamblee, you could save fourteen cents a gallon.
In today’s J&L Auto Service article, we’re focusing on the things you can do to improve your sedanfuel economy driving around Georgia. We’ll tell you the potential savings per gallon of gas at three dollars and fifty cents, and we’ll show a chart that also shows the savings at three and four dollars.
DOLLARS PER GALLON
TUNE UP 4%
The next item is replacing a clogged engine air filter. Your engine needs enough air to burn fuel efficiently for the best gas mileage. A clean air filter means you get plenty of air. The fact that the air’s clean protects your engine. That can save you up to ten percent or thirty-five cents a gallon.
DOLLARS PER GALLON
AIR FILTER 10%
Fixing a faulty oxygen sensor can improve economy by up to forty percent. That’s a whopping dollar forty in savings per gallon. Bring your car to J&L Auto Service in Chamblee and we’ll check your oxygen sensor.
DOLLARS PER GALLON
FAULTY O2 SENSOR 40%
Chances are that if your oxygen sensor is kaput your check engine light will come on. Now, there’s any number of things that could cause your check engine light to come on besides oxygen sensor problems. But if it’s on, get it checked out as soon as you can at J&L Auto Service.
Here’s an easy one for astute Chamblee motorists. Inflate your tires to the recommended pressure. That could save you three percent or eleven cents a gallon. Even a little drop in pressure will bring down your MPG, so check your tires every week.
DOLLARS PER GALLON
TIRE INFLATION 3%
Your sedan vehicle manufacturer has recommended a specific weight of motor oil. The recommendation is based on engine design and will give you the best protection. Using a heavier weight could cost one to two percent in reduced fuel efficiency, or up to seven cents a gallon.
DOLLARS PER GALLON
RIGHT GRADE MOTOR OIL 2%
Here’s one that’s free for Chamblee drivers that want to save income: Take it easy when you drive. Aggressive driving (we’ve all seen this on Chamblee roads), rocketing away from stop lights, standing on the brakes, punching it for lane changes – really takes a toll on your fuel economy.
Cutting out aggressive driving around Chamblee can save five percent or eighteen cents a gallon. Now on the interstate it gets really costly: thirty three percent or a buck sixteen a gallon. Think about that – and leave a little earlier.
DOLLARS PER GALLON
DRIVE AGRESSIVELY – MIN. 5%
DRIVE AGGRESSIVELY – MAX. 33$
A related item is exceeding the speed limit. For example, if the speed limit is sixty miles per hour on your Chamblee freeway, an additional five miles will cost seven percent or twenty-five cents a gallon. Fifteen miles per hour will cost you upwards of eighty cents a gallon.
DOLLARS PER GALLON
SPEED LIMIT – MIN. 7%
SPEED LIMIT – MAX. 23%
The last thing we’ll talk about is excess weight. Our sedans tend to accumulate a lot of things and the weight adds up. Clear out the trunk and only haul stuff when you really need it. For every one hundred pounds you can save two percent or seven cents a gallon.
Sorry honey, your brother can’t come with. It’d cost an extra thirty cents a gallon.
At J&L Auto Service we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV’s. But our Georgia friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there’re nearly as many diesel powered passenger cars as there are gasoline.
Here’s who’s announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in Georgia.
You may ask, why has it taken so long getting to Georgia and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that Georgia diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines. Recent government mandates to remove sulfur now opens up Georgia to the engines the rest of the world’s been enjoying for a long time.
Why are diesels so popular worldwide? Well, for starters, diesels get up to 30% better fuel economy than gas engines. And they last a lot longer. And modern diesel engines are refined, quiet and powerful – and there’s none of that black smoke we used to see.
Some people may think that diesels create more pollution. But, you need to rethink diesels. Environmental pollution standards for diesel cars and light trucks are scheduled to be as strict as they are for gasoline vehicles. A modern diesel engine is as clean as a gas engine.
You may also have heard a lot in the news about bio-diesel. The exciting thing about diesels is that they’re not limited to fossil fuels. They can run on fuel made from vegetable oil. There are refineries that make diesel fuel from cellulosic waste like woodchips from lumber mills. There’s even this cool new process where a special strain of algae is used to convert carbon dioxide, water and sunshine into bio-diesel. That’s still a ways off, but you can see that diesel can become a sustainable source of fuel.
And, there are not a lot of trade off’s with diesel in terms of performance. A modern passenger car diesel is very smooth, quiet and quick. Most folks wouldn’t notice any difference. For those who tow trailers and haul heavy loads, diesels will be an improvement.
Now diesel engines are heavy duty, so they cost more than gas engines. But they get better fuel economy – so the break-even point is largely dependent on the difference between Georgia gas and diesel prices at the pump and how many miles you drive. And diesels have a higher resale value.
Now, let’s get back to diesel maintenance. You have to keep in mind that most of the new diesels are just coming in, or will be over the next couple of years, so we don’t have the maintenance schedules to make direct comparisons yet.
But going off what we already have in Georgia, we can expect fluid drain intervals to be similar to gasoline engines. Diesels do require very clean fuel, air and oil, so their filters are much higher capacity than gasoline filters and cost more. The engine air filter needs to be changed more frequently as well.
Repair costs are similar. As with gasoline engines, proper maintenance is the key to long engine life and to avoiding repairs. So pretty much what we have come to expect with gas vehicles; coolant system service, transmission service, power brakes, power steering, differential, filters, fuel system, and so on. And the payoff for you, if you’re the kind that likes to keep your vehicles for a long time, is that a properly maintained diesel engine can last for hundreds of thousands of miles.
Hello, Chamblee auto owners. Let’s talk fuel filters. Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the engine.
Chamblee drivers don’t need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better an engine will run.
Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your sedan ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.
The harder your fuel filter works, the more often it needs to be replaced. Check with your sedan owner’s manual or J&L Auto Service to find out how often it should be serviced and how long you can expect it to last. You should change it before it becomes clogged. Your J&L Auto Service tech can help you with recommended replacement schedules.
If your fuel filter becomes clogged, your engine will sputter when you drive at Georgia highway speeds or when you accelerate rapidly. A clogged filter allows enough fuel to run the car at low speeds around town in Chamblee, but when you need a higher flow of fuel for faster speeds, or if you need a sudden burst of fuel, you just won’t be able to get it through the filter.
A clogged filter is actually dangerous. If you need to accelerate suddenly out of the path of danger, you just won’t have the power to do it.
Fuel filters have a bypass valve. When the filter becomes clogged, the valve allows some fuel to bypass the filter so the engine can keep running – just not enough to be running well.
That means, though, that dirty, unfiltered fuel is entering your engine. Instead of clogging up your filter, that dirt is now getting into your fuel injectors, where it can cause serious damage. Fuel injectors are expensive; fuel filters are cheap. It doesn’t seem like a difficult choice for Chamblee drivers.
Fuel filters are the epitome of preventive maintenance. They are cheap and easy to change, but neglecting them can lead to pricey repair bills. Some fuel filters are inside the fuel tank and cannot be routinely serviced – your honest J&L Auto Service tech will be able to tell you if this applies to your vehicle.
Good car care for Chamblee motorists means following recommended schedules for preventive maintenance, including changing your fuel filters. Take the auto advice offered at J&L Auto Service and in every owner’s manual and have your vehicle regularly inspected. It may save you money by preventing costly repairs, but it will also repay you in improved fuel economy, safety and peace of mind.
