Category Archives: Fuel System
Mount Juliet motorists know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your sedan 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 sedan engine.
Direct injection engines burn fuel more efficiently than conventional sedan 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 sedan 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.
Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the sedan 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 as well as delivering less power to the engine.
Mount Juliet car owners should understand that fuel injectors are not cheap to replace. Direct injection fuel injectors are even more pricey. 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. 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. 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, Mount Juliet car owners will enjoy better gas mileage and their fuel injectors will last for a long time.

There’s not much we can do about the price of gas in Mount Juliet Tennessee, but we do quite a bit about how much we use as we’re driving on our Mount Juliet 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 Nashville. 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.

Hi Mount Juliet drivers. Let’s talk fuel injectors. A fuel injector is a valve that delivers fuel to a vehicle’s engine. It has to deliver the precise amount of fuel, to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.
Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.
The pressure in a fuel injection system varies depending on its type. Many gasoline sedan engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.
Vehicles have one fuel injector for each cylinder in the engine. Your vehicle’s control computer constantly monitors the engine and various sensors in the vehicle and adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle’s engine. Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment to their performance. When an injector gets gummed up, it affects the pressure, pattern and timing of the fuel delivery. The result is a decrease in fuel efficiency and loss of engine performance for Mount Juliet car owners.
So it’s to Mount Juliet car owners’ advantage to keep their fuel injectors clean. That starts with keeping the fuel in your tank clean. High-quality fuel contains detergents and additives that help clean your engine. Brand-name fuel companies also deliver a more consistent quality of fuel to Mount Juliet car owners than do bargain Nashville area service stations.
The second way to keep your injectors clean is to keep your fuel filter clean. This filter screens dirt and rust out of the fuel as it travels from the tank to the engine. If the filter clogs up, fuel will bypass it and carry its load of dirt into the engine.
Mount Juliet car owners should check their owner’s manual to find out how often they should change their fuel filter. This should be part of your regular preventive maintenance. Also, remember that if you use bargain-brand or low-grade fuels, or if you drive an older vehicle between Mount Juliet, Mount Juliet and Nolensville , your filter will need to be changed more often.
You can also purchase cleaners at Conder’s Automotive that will protect your fuel injectors. These cleaners are added to the fuel tank. They work best at preventing build-up in your fuel injectors and can clean up small amounts of carbon, gum and varnish. But they won’t be able to clean a fully gummed-up injector. Read the labels before using any of these products for full directions on their use. If your fuel injectors are gummed up, you can get a professional deep cleaning service at Conder’s Automotive in Mount Juliet that will result in better MPG and improved vehicle performance.
Good car care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.
Something you’re going to be hearing a lot about around Mount Juliet, Tennessee is diesel engines. We’re not talking about semi-trucks and buses – We’re talking about diesel engine cars, pick-ups and SUVs.
Most people in Mount Juliet, Tennessee are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import auto manufacturers offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven’t been available in Mount Juliet, Tennessee. But that’s about to change.
In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in Mount Juliet, Tennessee so we are now ready to start seeing more diesel options offered to Mount Juliet drivers over the next few years.
Why are so many Mount Juliet car owners interested in diesel engines? Well first off, diesel fuel is more energy dense. There’s more power in a barrel of diesel fuel than there is in a barrel of gasoline. The result? Better performance and improved gas mileage.
Diesel powered vehicles get about 20 percent better gas mileage. And as for power – why do you think that the majority of new heavy duty pick-up trucks are being sold in Mount Juliet with diesel engines?
If you think back to the late 1970’s and early 1980’s, you may shudder when you think of the diesel powered cars of the day – noisy, smoky, under-powered beasts that rattled and shook their passengers. Modern diesels sold in Tennessee have evolved considerably.
They are quiet, clean – and powerful. They’re so refined that many Mount Juliet motorists can’t even tell they’re riding in a diesel powered sedan. In addition to fuel savings, diesels generally last longer than gasoline engines because of their heavy duty construction.
Another thing the Mount Juliet green crowd takes advantage of is the use of bio-diesel in diesel vehicles. Bio-diesel is made from vegetable oil – even recycled cooking oil from Mount Juliet restaurants. There is a lot of buzz about Hybrid cars in Tennessee. Look to diesel-electric hybrids in years to come to make a good idea even better.
Every year, manufacturers introduce new diesel models. Look for diesels in domestic light trucks, SUVs and passenger cars. Import auto makers have plans to bring more of their outstanding diesel engines to Mount Juliet, Tennessee as well.
New Mount Juliet diesel owners need to know that properly maintaining a diesel engine is somewhat different than a gasoline engine. Fluid change intervals are different. Emissions control devices have to work harder to filter diesel fuel and to scrub the exhaust so you will need to pay attention to that. And the fuel injection system operates at much higher pressures than gas fuel injection systems, so it’s important to keep your fuel system clean with a diesel.
The good news is that Conder’s Automotive in Mount Juliet is keeping up with the new diesel technology and will be able to advise you on maintaining your diesel.
When we tell you to look for more diesels on Mount Juliet streets, you won’t be looking for smoky tail pipes as a clue. You also won’t be listening for that familiar big rig rattle. And, you certainly won’t be waiting for them at the stoplight, because modern diesels are as quick as their gasoline counterparts.
From all of us at AutoNetTV, ten four, good buddy.
Hello, Mount Juliet car 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.
Mount Juliet car owners 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 Conder’s Automotive 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 Conder’s Automotive technician can help you with recommended replacement schedules.
If your fuel filter becomes clogged, your engine will sputter when you drive at Tennessee highway speeds or when you accelerate rapidly. A clogged filter allows enough fuel to run the car at low speeds around town in Mount Juliet, 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 Mount Juliet drivers.
Fuel filters are the epitome of preventive maintenance. They are cheap and easy to change, but neglecting them can lead to costly repair bills. Some fuel filters are inside the fuel tank and cannot be routinely serviced – your friendly Conder’s Automotive service professional will be able to tell you if this applies to your vehicle.
Good car care for Mount Juliet drivers means following recommended schedules for preventive maintenance, including changing your fuel filters. Take the auto advice offered at Conder’s Automotive 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 MPG, safety and peace of mind.
There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn’t seem right.
Fortunately a lot of those things can be taken care of in routine maintenance. They may not be easy to remember, because it is a long list, but your service center at Conder’s Automotive can help you know what’s scheduled to be taken care of.
Some of us in Mount Juliet Tennessee really don’t look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.
But automotive maintenance is all about prevention, and addressing small problems before they get big. Let’s take the fuel filter for example.
You may not know this but the median age for private vehicles on our Mount Juliet Tennessee roads is over nine years. When cars get older, five years or so, they’ve accumulated a lot of dirt and rust in their gas tanks. If that dirt gets into the engine it can cause thousands of dollars worth of damage. So somewhere between that dirty gas tank and the price of a great vacation – is the lowly fuel filter: a very inexpensive part that doesn’t cost too much to replace. And your car’ll just run better too.
A clogged fuel filter can’t let enough fuel through. You might notice at first that your car is running fine around town, but struggles or sputters on the Mount Juliet Tennessee freeway or when you accelerate. Enough fuel can’t get through to meet the demands of higher speed. If it gets bad enough your engine might just shut off or not start at all, which could be dangerous.
Some fuel filters have a bypass. When they get clogged, they allow dirty fuel to move around the filter element so dirt ends up in the engine. We’ve already talked about how expensive that can be.
The fuel filter is even very important for newer cars. The fuel is still dirty even if there isn’t rust in the tank. It’s just that the fuel filter will need to be changed more frequently as the vehicle gets older.
How often should you change your fuel filter? Check your owner’s manual. Your Mount Juliet Tennessee service advisor at Conder’s Automotive can tell you as well. It’s usually around thirty thousand miles or so. Ask if it’s time for a full fuel system cleaning as well. They often go hand in hand.
It’s good to know that your Mount Juliet Tennessee service center has your back. When you’re motivated to maintain your vehicle’s performance and to reduce operating costs, you’ll think of Conder’s Automotive as your ally – and maybe even your memory.
No one in Mount Juliet, Tennessee likes to spend a chunk of change at Nashville gas pumps. Rising Tennessee fuel prices, however, have spurred Mount Juliet car owners to focus on how to improve their fuel efficiency. North Americans literally drive billions of miles less each month during times of high fuel prices. But we still need to drive (we are car-loving Americans, after all!), so it makes sense to try and increase our fuel economy however we can.
Let’s look at a real life example of one of our AutoNetTV producers. He has one of those really big SUVs. Lots of kids and horses to haul around, you know. His family was planning a four day camping trip. Here’s what he did to cut his fuel costs:
First, he installed a new, high flow engine air filter. Then he had his Mount Juliet service center change his oil, flush his cooling system and service his front and rear differentials along with the transfer case. He also had a fuel system cleaning, replaced his PCV valve and breather element. He also made sure his tires were up to the recommended pressure.
Now this cost several hundred dollars. But keep in mind, it all needed to be done anyway – it was all scheduled, and some of the work was overdue.
So he headed out, loaded with nine people and pulling a ton of trailer with everything needed for four days of camping. When the trip was over, he tallied his fuel efficiency. Turns out, he got the best fuel economy on that vehicle up to that point. It had improved 25 percent! He saved $48.00 on that trip alone. And the savings keep on coming every day.
Here’s a quick summary of what you can do to save fuel in Mount Juliet, Tennessee. First get caught up on your essential routine maintenance. Nearly every scheduled service item can boost MPG. If it’s time for a tune-up, git’er done at Conder’s Automotive. That’s a big item.
If your check engine light is on, have your friendly Conder’s Automotive service advisor figure out why and fix it. Check engine problems can be real gas wasters.
Proper tire pressure and wheel alignment can really help Mount Juliet auto owners as well. Try not to carry around a bunch of stuff. An extra hundred pounds can cost a mile per gallon.
Now you may not want to hear this, but the single biggest fuel waster for most Nashville folks is their right foot. Zooming away from stop lights and hot rod lane changes really waste fuel. Take it easy on Tennessee freeways and Mount Juliet streets: don’t speed and plan ahead.
Finally, you may have noticed that we haven’t mentioned any magic pills or devices that will double your mileage. That’s because there aren’t any. Some may help a bit, but there are a lot of “miracle fuel saver” scams in Tennessee. Don’t shell out any bucks to swindlers, you need it to buy gas!
Do some research and check with your technician at Conder’s Automotive in Mount Juliet before spending your hard earned cash.
Here’s a question for Mount Juliet, Tennessee auto owners: How long have you been enjoying the romantic glow of your check engine light?
Hey, it’s not there to create ambiance; it’s a warning that something’s wrong. (And, by the way, Homer Simpson’s fix of covering it with tape is not a good idea.)
If your check engine light comes on, check your gas cap. A loose gas cap can cause a false sensor reading that’ll make the check engine light turn on.
If your date’s eyes are smoldering in the soft glow of the check engine light, try to think of all the gas money you’ll save by getting it fixed. Give Conder’s Automotive a call when you are ready: 615-758-1515
The team at Conder’s Automotive in Mount Juliet and Tennessee car owners are all talking fuel economy right now. Better gas mileage. Fewer emissions. Mount Juliet car owners want to save the environment and their pocketbooks.
And we all know—or should know—that preventive maintenance will help maximize gas mileage. But is there something more Mount Juliet drivers can do? After all, some of us Mount Juliet 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 Mount Juliet to Mount Juliet. And that means buying more gas in Mount Juliet 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 Tennessee? Do you really need your golf clubs every time you leave your Mount Juliet 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 Mount Juliet. You’d be surprised how much weight you’re lugging around Mount Juliet 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 Mount Juliet 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 Mount Juliet.
