Fuel Injection Keeps Getting Better For Medford Motorists

Medford 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 fuel efficiency. 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 gas mileage.

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 Medford auto owners 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 Medford drivers. 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 Medford Automotive in Medford. 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.

Medford Automotive: Good Service And Good Fuel Economy

Most Medford and Jacksonville motorists want to save on gas and seek our advice on improving fuel economy. At Medford Automotive, we are frequently asked, however, if it is really worth the extra effort. Just how much money can Medford car owners actually save?

The US government has a website dedicated to helping us use less fuel. It presents the cost savings in a way Medford auto owners can relate to and is relevant for all vehicles. Let me give you an example: Having your Car engine properly tuned, can save up to 4%. If you’re paying three-fifty for a gallon of gas in Medford, you could save fourteen cents a gallon.

Medford Automotive: Good Service And Good Fuel Economy

In today’s Medford Automotive article, we’re focusing on the things you can do to improve your Car gas mileage driving around Oregon. 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 $3.00 $3.50 $4.00
TUNE UP 4% .12 .14 .16

The next item is replacing a clogged engine air filter. Your engine needs enough air to burn fuel efficiently for the best fuel economy. 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 $3.OO $3.50 $4.00
AIR FILTER 10% .30 .35 .40

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 Medford Automotive in Medford and we’ll check your oxygen sensor.

DOLLARS PER GALLON $3.00 $3.50 $4.00
FAULTY O2 SENSOR 40% 1.20 1.40 1.60

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 Medford Automotive.

Here’s an easy one for wise Medford 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 fuel efficiency, so check your tires every week.

DOLLARS PER GALLON $3.00 $3.50 $4.00
TIRE INFLATION 3% .09 .11 .12

Your Car 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 $3.00 $3.50 $4.00
RIGHT GRADE MOTOR OIL 2% .06 .07 .08

Here’s one that’s free for Medford auto owners that  want to save income: Take it easy when you drive. Aggressive driving (we’ve all seen this on Medford roads), rocketing away from stop lights, standing on the brakes, punching it for lane changes – really takes a toll on your fuel efficiency.

Cutting out aggressive driving around Medford can save five percent or eighteen cents a gallon. Now on the freeway it gets really costly: thirty three percent or a buck sixteen a gallon. Think about that – and leave a little earlier.

DOLLARS PER GALLON $3.00 $3.50 $4.00
DRIVE AGRESSIVELY – MIN. 5% .15 .18 .20
DRIVE AGGRESSIVELY – MAX. 33$ .99 1.16 1.32

A related item is exceeding the speed limit. For example, if the speed limit is sixty miles per hour on your Medford 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 $3.00 $3.50 $4.00
SPEED LIMIT – MIN. 7% .21 .25 .28
SPEED LIMIT – MAX. 23% .69 .81 .92

The last thing we’ll talk about is excess weight. Our Cars 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.

Maintaining Your Diesel in Medford

Diesel engines have been used extensively in Europe and Asia for many years. They haven’t been as common in Medford 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 Medford car owners driving diesel-fueled vehicles on the road, especially in passenger cars and SUV’s.

Diesels are popular in Medford 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 Oregon 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 Medford, we may soon see bio-diesel produced from algae. These fuel sources will lessen Medford 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 Eagle Point people don’t notice a difference in driving one or the other. If you haul heavy loads or tow a trailer in Jacksonville, however, the diesel is a definite improvement.

So, you may be asking, if diesels are so great, why don’t all Medford motorists 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 Oregon. The better fuel economy 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 Medford. But now, with higher volatility in the prices of both gasoline and diesel fuel in Oregon, that cost difference is less definitive. Whether a diesel or gas engine is more expensive for Medford auto owners depends now on the current price of fuel in Oregon and how many miles you drive.

Consider also that diesel-powered vehicles have a high resale value in the Medford area, and the costs of owning and operating a diesel vs. a gas-powered vehicle in Oregon 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 Medford than those for gasoline engines. The engine air filter must be changed more frequently as well.

The costs for car care and repairs in Medford are similar. Wait, you may be thinking, but you just told me that filters are more pricey 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 Medford Automotive 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 Medford driver and their driving habits. Now that you know the facts, you can make an informed choice based on your own priorities and needs.

The Medford Automotive Guide to Saving Fuel: Car Weight

The team at Medford Automotive in Medford and Oregon car owners are all talking gas mileage right now. Better gas mileage. Fewer emissions. Medford motorists 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 Medford drivers can do? After all, some of us Medford 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 Medford to Central Point. And that means buying more gas in Medford and producing more emissions.

Of course, your Car’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 Car. Are you hauling a bunch of unnecessary weight around Oregon? Do you really need your golf clubs every time you leave your Medford 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 Medford. You’d be surprised how much weight you’re lugging around Medford 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 Medford 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?

Engine Air Filter From Medford Automotive


Many Medford drivers have found themselves in the following situation: they go to get their oil changed and their honest Medford Automotive tech recommends a new engine air filter. They say yes, but don’t know what an air filter is or what it does.

If this has happened to you, rest assured that you did the right thing by getting a new one. But you should never be too embarrassed to ask your Medford Automotive service specialist for more information. It’s your bucks and you have a right to understand what you’re paying for.

Let’s review: “What does an air filter do??”:

Air is the focus of this discussion. What is the air like outside in Medford right now? Can you see any smog? Is it full of pollen? How about dust? Anyone in Oregon with hay fever can tell you that there’s plenty in the air that you can’t see. Well, the engine air filter’s important job is to clean that air before it goes into your Car engine, to mix with the fuel and be burned. Without an engine air filter, the inside of your Car engine would be extremely dirty from all the gunk that was burned in the cylinders.

In fact, for every gallon of gas you burn, your Car engine needs 12,000 gallons of air. That little filter does a very big job. It’s no wonder that the air filter gets dirty and needs to be replaced. Think about a vacuum cleaner. When the bag gets full of dust and dirt, the vacuum doesn’t clean as well. It can’t move enough air to create good suction. A clogged engine air filter is the same way – the Car engine can’t get enough air to burn the fuel efficiently. That means less power and reduced fuel economy.

That’s why your vehicle manufacturer has recommended that you change your filter at regular intervals. Of course the Medford conditions you drive in will affect how quickly the filter gets dirty. If you drive in Oregon where it’s very dusty or where there’s lots of pollen or pollution, you may need to change the filter sooner. The filter is easy to check visually, so your honest Medford Automotive service advisor can quickly make the call. He might recommend immediate replacement, or simply let you know that it is getting close and that you’ll need to replace it soon – like at your next oil change.

Because a severely dirty Car air filter hurts your gas mileage, many Medford car owners find that a new air filter pays for itself in better gas mileage before the next oil change. They also make premium air filters that have been proven to increase your horsepower and torque. If more power is important to you, a high performance air filter is some of the cheapest horsepower you can buy.

The better your car breathes, the better it runs – kind of like Medford people. And don’t worry – if you have a question or don’t understand a recommendation just ask your Medford Automotive technician.

Higher Mileage Service Intervals For Medford

Medford car owners have probably noticed that the government mandates a lot of equipment on cars: emission devices and control computers; safety equipment like airbags; and crash worthiness requirements. All of this is great for the motoring public in Medford but it does add quite a bit to the price of a new car in Oregon.

Because new cars are more expensive, Medford residents are driving their old cars longer. The average car is now over nine years old. 68% of vehicles on the road have more than 75,000 miles/120,000 kilometers. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today’s cars are up to the challenge – but they need a little help to keep on going.

Some owner’s manuals don’t outline service requirements and schedules at higher mileage. Of course, that doesn’t mean it doesn’t have to be done. In fact, it’s more important than ever for Medford drivers to stay on top of routine auto maintenance for cars with more than 120,000 miles/190,000 kilometers. Just extend regular service intervals out: for instance a service that’s recommended every 24,000 miles/38,000 kilometers should be performed at 24,000 mi/38,000 km; 48,000 mi/77,000 km; 72,000mi/116,000 km, 96,000 mi/154,000 km; and on and on.

Because of the additional stress older engines experience, the severe service maintenance schedule may be more appropriate than the regular schedule. Watch for leaks – seals and gaskets dry out over time and do not hold the fluids as well as they used to. If you don’t already have one, it is more critical than ever to get a good technician, like any one of the automotive professionals on our team at Medford Automotive. There are some services and replacements that are scheduled after you put some clicks on the odometer, like timing belts, valve train adjustments, suspension, anti-lock brake service, air bags, etc. And unexpected repairs down the road are just par for the course.

Check for unusual sounds, smells or the way your car feels. These could be hints for Medford drivers that trouble is brewing. Better to catch it early before it turns into an expensive repair. Regular wash and wax will help maintain your car’s appearance. One of the things Medford car owners can do to really help a high mileage vehicle is to begin using high mileage formulation fluids. There are special engine oils, coolants, transmission fluids and power steering fluids that are formulated for cars that have higher mileage.

High mileage oil is designed to condition seals and gaskets, reduce wear and avoid premature burn off. Older Car engines are dirtier inside – and dirty engines contaminate their oil faster. High mileage oil has special additives that clean the engine, removing sludge deposits over time. The result is less stress on the engine, better fuel economy and excellent wear protection. Come into Medford Automotive in Medford for a checkup.

Studies have even shown that using high mileage fluids early will actually prevent some of the problems of high kilometer vehicles. So once you hit around 50,000 mi/80,000 km, consider stepping up to high mileage formulations. The fluids cost a bit more than standard fluids in Medford because of the additional additives, but they can be worth their weight in gold for Medford car owners in terms of preventing pricey repair costs down the road.

It does cost more for motorists to properly maintain a higher mileage vehicle in Medford – but it’s much cheaper than a new car payment!

Fuel Saving Tip: Dirty Oil In Your Medford Car

If you’re a quart low in your Car, 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 Medford area.

Clean Oil for your Car The same goes for dirty oil; it doesn’t reduce friction properly. The result is you get to watch those numbers at your local Medford 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.

Fuel Saving Tip: Medford Tune Up

Have you ever gone to Medford 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.

Fuel Economy 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 Medford service advisor at Medford Automotive what he thinks.

…Just be careful not to say you want to make beautiful music together – that kinda makes us uncomfortable.

Finding Vehicle Recall Information In Medford Oregon

No matter how well they’re made, vehicles in Medford, Oregon will have design or manufacturing problems.

And when the government thinks a problem is really serious for people in Medford, Oregon, they require the auto maker to issue a recall notice and fix the car free of charge. The auto maker then tries to contact everyone in Medford, Oregon who owns that type of car to get the recall work done. Perhaps you have received a postcard notifying you of a recall issue on your car. Because these recalls always affect safety, Medford car owners should take them seriously. This isn’t difficult to do because it’s easy to see if a vehicle’s being recalled.

Finding Vehicle Recall Information The government has links on its websites, or just visit AutoNetTV for links. There are many websites with free recall information and searches. There’s CarFax, AutoByTel and the DMV.

Recalls are serious, but not all that common. But sometimes there are less key issues, and for these, car makers issue a Technical Service Bulletin, or TSB, that tells service centers like Medford Automotive how to repair a frequent or difficult problem.

The pros get updated information through subscription plans, also available in consumer versions for a reasonable cost. So when manufacturers recalls occur, get the work done, and keep you and yours safe.
