Today we’re talking about fuel system cleaning. The first thing to know is how important it is to have a clean fuel system. You need fuel to go, and the cleaner your fuel system, the more efficiently the fuel will burn. That means more power and better fuel economy.

A clean fuel system saves money at the pump. We guess you could say, it all starts and ends at the pump. One of the most important things you can do to keep your fuel system clean is to buy good quality gas. Major brands have detergents that keep gum and varnish from rapidly building up in the fuel system.

So buying cheaper gas can actually cost you in the long run. Now, most cars on the road are more than five or six years old. That means they’ve had time for some dirt and rust to start accumulating in the fuel tank. This junk needs to be filtered out of the fuel before it hits your engine. That’s the fuel filter’s job.

When the fuel filter is clogged, the dirty fuel will bypass the filter and go on up to the engine where it can clog fuel injectors and get into the cylinders. That could do some damage. So you should have your fuel filter changed when recommended. Check your owner’s manual or ask your service advisor if your fuel filter is due for replacement.

The fuel then goes up into the throttle body. This is another area where varnish and gum can accumulate. A professional fuel system cleaning will use a combination of special cleaning chemicals and old fashioned swabbing to clean out the throttle body. Now, the fuel injectors are the last stop in the fuel delivery system.

It’s real important to keep those fuel injectors clean. The fuel injectors need to deliver a precise amount of fuel, at exactly the right time, in a particular spray pattern. They just can’t do that if they’re dirty. Dirty fuel injectors really rob power and waste fuel.

It is important for the fuel system proper, but there are a couple other things that will help keep your engine clean as well. Of course, air is mixed with the fuel before it’s burned. Dirty air means dirt gets into your engine, so you need to replace your engine air filter when it’s dirty.

The PCV value routes unburned fuel that escapes into the lower engine back up into the intake system to be burned. A sticky PCV valve needs to be replaced to make sure that system is working properly and the breather filter needs to be replaced if it’s dirty as well.

Do all these things and your engine’s air and fuel will be as clean as possible. You’ll get much better fuel economy and better power

Diesel Maintenance For MA

Thursday, January 21st, 2010

At Preferred Auto & Tire 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 MA 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 MA.

You may ask, why has it taken so long getting to MA and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that MA 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 MA 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 MA 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 MA, 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.

Preferred Auto & Tire Often Asked About Premium vs. Regular Gas

Tuesday, November 3rd, 2009

People in Weymouth MA often ask the question: “Will using premium gas make my car run better?” The answer is simple. But first, let’s talk about what exactly premium gasoline is.

Different grades of gasoline have different octane ratings. Regular gasoline has the lowest octane rating and premium the highest. Most gas stations around Weymouth MA also carry a mid-grade that falls in between the two. The octane range for the different grades of gas varies by region due to altitude differences.

Engines require different octane ratings because of design differences. For example, turbocharged engines usually require premium gas.

There’s a sticker on your gas tank filler lid that tells you the minimum octane rating your manufacturer recommends.

For help identifying the type of gasoline your engine needs, come by our Weymouth MA service center:
Preferred Auto & Tire
511 Main Street
Weymouth , MA 02190
781-331-8944

Read your owner’s manual carefully to see if it’s acceptable to use lower grades. With some cars in Weymouth MA it is; the engine control computer can adapt. You’ll lose some performance, but won’t do damage. With other engines, using a lower grade of fuel could result in serious damage; so you don’t want to save a couple of bucks at the pump only to pay it out a hundred fold at the repair shop.

Your car will run best on the grade of gasoline recommended by the manufacturer.

Today’s computer controlled vehicles are optimized to run well on the recommended grade of fuel. Using a higher grade than is recommended will not give you any additional performance or better fuel economy.

Regulations require detergents for all grades of gasoline, so your engine will have the same protection, regardless of the grade of fuel you use. If you do hear some knocking or pinging from your engine, take it seriously and get your sedan into Preferred Auto & Tire. It may be a sign that you need a tune-up or some other repair.

In times of high gas prices, we’re all conscious of making our fuel dollar go further as we drive around Weymouth MA. Be sure to use the right gas for your car. Keep your tires properly inflated and your vehicle well maintained and you will get the best fuel economy possible.

To Save Gas Around Weymouth : Keep Up with Your Scheduled Service

Wednesday, September 9th, 2009

One topic that hits the news in Weymouth on a regular basis is the price of gas. The answer for some people in Weymouth is to buy a more fuel efficient vehicle. For the rest of use, we need to improve our fuel economy anyway we can.

Following recommended service intervals by coming into Preferred Auto & Tire is one of the best ways to keep your car running efficiently. That means better fuel economy. When you give it some thought, it only makes sense. Dirty oil or transmission fluid can’t lubricate or clean. That means more drag which reduces fuel economy.

Keeping up with scheduled oil changes and transmission services will save gas.

Dirty engine air filters are another efficiency pirate. They rob your engine of enough air to effectively burn the fuel, so you need more gas to get the job done. Replacing a dirty air filter can pay for itself in fuel savings before the next oil change.

You can imagine what dirty fuel injectors can do to your sedan as you drive around Weymouth . If your owner’s manual recommends a fuel system cleaning, come into Preferred Auto & Tire and ask us to get it done for you.

A simple, but very effective way to save gas is to keep your tires properly inflated. Low tires can cost you up to a mile per gallon. Check your tire pressure when you gas up – or at least once a month.

Introduction to Diesels for Weymouth MA

Sunday, June 7th, 2009

Something you’re going to be hearing a lot about around Weymouth , MA 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 Weymouth , MA 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 Weymouth , MA. 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 Weymouth , MA so we are now ready to start seeing more diesel options offered over the next few years.

Why are so many 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. That means better performance with better fuel economy.

Diesel powered vehicles get about 20 percent better fuel economy. And as for power – why do you think that the majority of new heavy duty pick-up trucks are being sold 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 are nothing like that.

They are quiet, clean – and very powerful. They’re so refined that many people can’t even tell they’re riding in a diesel powered car. In addition to fuel savings, diesels generally last longer than gasoline engines because of their heavy duty construction.

Another thing that intrigues the environmentally conscious is that it’s possible to use bio-diesel as fuel. Bio-diesel is made from vegetable oil – even recycled cooking oil from restaurants. Hybrid cars have gotten everyone’s attention these days. Look to diesel-electric hybrids in years to come to make a good idea even better.

Every year, manufacturers are planning more diesel offerings. Look for diesels in domestic light trucks, SUVs and passenger cars. Import marquees have plans to bring more of their outstanding diesel engines to Weymouth , MA as well.

Now you should 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 very important to keep your fuel system clean with a diesel.

The good news is that your local Weymouth , MA service center 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, 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.

Fuel System Cleaning to Improve Performance in Weymouth , MA

Tuesday, June 2nd, 2009

All modern vehicles come with fuel injection systems, so it’s a topic we all need to know something about. All new cars and trucks sold in Weymouth , MA over the last 30 years or so have come with fuel injection systems.

The fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount, at the right time; to be mixed with air and burned in the engine.

So how many fuel injectors does your car have? There’s one for each cylinder. So four, six or eight for most folks in Weymouth , MA. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty sophisticated part.

Preferred Auto & Tire can help you with a fuel injector cleaning service. What’s the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. The fuel needs to be sprayed in a particular pattern as determined by the engine design.

Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn’t get burned as efficiently as it could. That robs performance and wastes fuel.

What about dirty fuel – how does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high quality fuel. Its real tempting to shop for bargains with fuel prices as high as they are, but major brands in the Weymouth , MA area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is the next device in the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it’s clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It’s important to replace the fuel filter when your manufacturer recommends it. That’s part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines we’re starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There’s no room for dirt and gum in a precision part like that.

There are a lot of good products available in Weymouth , MA that can clean fuel injectors. They’re best used to prevent fouling in the fuel injectors. Many can’t clean a seriously gummed up injector – that requires a professional deep cleaning. But putting the cleaner in the fuel tank after you’ve had Preferred Auto & Tire take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

Give us a call if you think your sedan may be ready for a fuel injector cleaning.

How Do You Save Gas?

Wednesday, April 8th, 2009

No one near Weymouth , MA likes high fuel prices. But if one good thing has come about, it’s that people are really focused on how to reduce their fuel consumption. North Americans literally drive billions of miles less each month during times of high fuel prices. But we still need to drive, 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 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 value 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 had turned in the best fuel economy he had ever gotten on that vehicle. It had improved 25 percent. He saved $48.00 on that trip alone. And the savings keep coming every day.

Here’s a quick summary of what you can do to save fuel with your Weymouth , MA vehicle. First get caught up on your routine maintenance. Nearly every scheduled service item can save you some fuel. If its time for a tune-up, git ‘er done. That’s a big item.

If your check engine light is on, have Preferred Auto & Tire figure out why and fix it. Check engine problems can be real gas wasters.

Proper tire pressure and wheel alignment can really help 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 MA people is their right foot. Zooming away from stop lights and hot rod lane changes really waste fuel. Take it easy, 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 scams. Do some research and check with Preferred Auto & Tire before spending your hard earned cash.

Professional Fuel System Cleaning

Thursday, March 12th, 2009

Getting enough fuel to your engine is very important for performance, fuel economy and safety. In order to accomplish this, your fuel system needs to be clean.

Today’s production cars have fuel injectors, rather than a carburetor. The injectors need to be cleaned from time to time in order to deliver the fuel with the correct pressure, spray pattern and volume.

You can buy fuel system cleaners that you just pour into your gas tank that can help maintain an already clean fuel system, but can’t do a major cleaning. For that, you need to see Preferred Auto & Tire. They have the tools and chemicals to do the job right. Preferred Auto & Tire can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently.

You’ll find Preferred Auto & Tire at 511 Main Street in Weymouth , MA 02190. Or just give us a call at 781-331-8944 to schedule an appointment.

You’ll enjoy more power, better gas mileage and reduced exhaust emissions. The cleaners also help prevent rust and corrosion in your fuel system and lubricate vital engine parts.

And, as with all maintenance, it can help prevent costly repairs that can happen because you didn’t take preventative steps. Check with your service technician at Preferred Auto & Tire and see when your car is scheduled for a fuel system cleaning.

Higher Mileage Service Intervals

Thursday, March 12th, 2009

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, but it does add quite a bit to the price of a new car.

Because new cars are more expensive, MA drivers are using 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 specify service requirements at higher mileage. That doesn’t mean it doesn’t have to be done. In fact, it’s more important than ever to stay on top of routine 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. It is also time to make sure you have a good technician like the pros at Preferred Auto & Tire in Weymouth . 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 that trouble is brewing. Better to catch it early before it turns into a costly repair. Regular wash and wax will help maintain your car’s appearance. One of the things you can do to really help your high mileage vehicle is to begin using high mileage formulation fluids. There are special engine oils, coolants, and transmission and power steering fluids that are formulated for cars that have a higher mileage.

High mileage oil is designed to condition seals and gaskets, reduce wear and avoid premature burn off. Older 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.

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 because of the additional additives, but they can be worth their weight in gold in terms of preventing repair costs down the road.

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