What do you think?  Do you love cars?  You might think that someone who spends nine hours a day, six days a week with cars would get really tired of them.  But surprisingly, the opposite is true.  I love cars!  I love cars and trucks of all shapes and sizes.   I love to listen to the roar of the engine when I turn the key in the ignition.  I enjoy watching the wheels on my car spin and shine as I drive past a wall of glass or mirrors.   And seeing a sleek, shiny car hurling toward me on the highway makes me grin.   I love to sit at a stoplight with the knowledge that if I wanted to show off, my car has the power to beat the car next to me off the line every single time!

I also enjoy repairing cars.   Figuring out why a car is running poorly and then repairing it gives me a huge sense of satisfaction!  Working on and repairing cars  can be like solving a very difficult puzzle.  And I like puzzles!

If you love cars like I do and have some extra time, than you might want to check out the Denver Auto Show that is taking place this week.  The Denver Convention Center will be filled with cars and the people who love them!  So if you just enjoy looking at cars or if you’re in the market for a new car and would like to see what’s available, consider taking some time and join them!

If you love looking at cars, but not repairing them, and you need to have your car repaired,then come in and see us or give us a call at (303) 691-2760.

Fuel Octane

by Leave a Comment

At this time in our nation, when fuel prices are increasing at an alarming rate, we can save money at the pump if we understand fuel octane and how it affects our vehicles.

Modern engines use fuel  injectors run by computers to accurately control their air/fuel mix.  In order to get an accurate air/fuel mix in the fuel injectors and computers, the proper fuel must be used for that engine.  The difference in the name and price of the fuel is based on the gasoline’s “octane”.  In order to determine a fuel octane rating, the fuel is subjected to two testing methods, the motor method and the research method.  The motor method runs the gas in an engine running under load, and the research method runs the gas in a free-running engine.  The fuel octane rating is the average of those two tests.

The fuel octane rating tells you how much the fuel can be compressed before it spontaneously ignites.  In internal combustion engines, the compressed fuel-air mixtures have a tendency to ignite prematurely rather than burn smoothly, and when gas ignites by compression rather than because of the spark from the spark plug, it creates engine knock, a rattling or pinging sound in one or more cylinders.   The fuel octane rating is a measure of a fuel’s resistance to engine knock.

Regular fuel has a an octane rating of at least 87.  The octane rating of  “mid-grade”  gasoline ranges from 88-90.  “Premium”  fuel octane can vary depending on the state where it is purchased but is usually higher than 90 in most states.

Most vehicles today are designed to run on Regular 87 octane fuel, but it’s a good idea to check your owner’s manual for the correct fuel octane rating recommended for your vehicle.  Some people have the mistaken idea that if you use a higher octane fuel in your car, you’ll increase the engine’s power or get better mileage.  High octane fuel doesn’t do a better job than regular octane gas in preventing engine deposits from forming, or removing them, or in cleaning the engine.  If your vehicle is designed to run on 87 octane, a higher octane fuel won’t improve mileage or increase its power.  If your engine runs well and doesn’t knock or ping on low octane fuel, than you don’t need to spend more money on a higher octane.  Don’t pay a premium price for something that you don’t need.

Why Is My Check Engine Light On?

by Leave a Comment

One of the most commonly asked question among drivers is, “Why is my check engine light on”?  Although this is a simple question to ask, it’s not always as simple to answer.

All of our vehicles are equipped with a computerized engine management system (ECM) and the check engine light is a part of this system.  The ECM alerts us to possible problems inside the engine or inside the transmission that have an impact on the emissions system.  Check engine lights may be a graphic of an engine or a similar icon.  It can also be words, “check engine” or “service engine”.  Some vehicles use a yellow check engine light as a caution light that tells you to have your vehicle checked soon and a red check engine light that means your vehicle needs immediate attention.  Every car’s display is different, so it’s a good idea to make yourself familiar with how your particular make and model of vehicle works.  The check engine light is usually amber or red in color and has two stages, a steady light or a flashing light.  A steady check engine light signals minor problems, while a flashing check engine light usually means there is a serious problem in the ECM.

The cause of why your check engine light is on depends on your particular issue, but here are some general malfunctions that cause the check engine light to come on.

  • A misfire in your engine.  A misfire can cause catalytic converter damage if it’s not resolved quickly.  The catalytic convertor works to reduce exhaust gases.  It converts carbon monoxide and other harmful materials into harmless compounds.  Replacing a catalytic converter can be costly, so have the engine checked as soon as possible by a certified mechanic.
  • A failure in the emission control system.  The emission control system contains many active sensors that work to reduce the amount of pollution released into the air.  One of those sensors is an oxygen sensor that reads the air and fuel mixture.  If that mixture is out of the acceptable range or if you have  a faulty sensor, it won’t provide the correct data to the computer and the check engine light will go on.
  • Brittle, cracked or worn spark plugs.  Worn spark plug wires can lead to an electric misfire inside the engine.  If the wires are worn out, they should be changed as soon as possible.
  • A loose gas cap.  When it’s loose or cracked, fuel vapors leak out and can throw off the whole fuel system.  Sometimes when the cap is put on incorrectly the check engine light will come on.  If the light stays on for more than a day or two, have your mechanic run an on-board diagnostic to see if there is a code in the system indicating a more serious problem.

Check engine lights help you and your mechanic to keep your car running smoothly.  So the next time your check engine light goes on, don’t ignore it.  Come in and see us or call (303) 691-2760 and let us help.

 

Power Steering Problems

by Leave a Comment

Are you having power steering problems with your car?  All vehicles with power steering only need a small amount of effort on our part to turn the wheel if everything is working properly.  Each power steering system is made up of the power steering pump, valves, gears and power steering fluid, that all work together to ensure that you can steer your car quickly and easily.  Power steering pumps can develop large leaks or begin to fail just from every day wear and tear and if left alone can cause serious power steering problems.  Also the power steering fluid can become dirty and starts to break down by the heat generated in the gears.  This can lead to increased wear in the pumps, valves and gears and eventually will lead to expensive repairs.   Here are a few signs to watch out for:

Sluggish or stiff steering.  Stiff steering in cold temperatures or when turning at slow speeds can be a sign of a power steering problem.

Squeals or squeaks–  A squealing sound when you’re turning, or driving slowly can be a sign of power steering problems.

Chattering in the steering system– A chattering or squeaking noise from under the hood when you first start your car can be a sign of power steering problems.

If you have noticed any of these symptoms recently, we recommend bringing your car in for a power steering system service.  This is a preventative service that is done to flush the power steering system and remove sludge and contaminants from the entire system, including the pump, rack and pinion, and lines.  Once the old fluid is flushed, new power steering fluid is added.  The new fluid performs in subzero temperatures and optimizes cold weather performance and reduces squealing and hard or inconsistent turning.  As I said before, this is a preventative service.  A preventative service only benefits us if we use it before there is serious damage done!  If you have had any of these symptoms for an extended length of time, it is very possible that your vehicle already has serious power steering problems.  So don’t wait any longer, give us a call at (303) 691-2760 or bring your car into the shop.

 

Automotive Brakes

by Leave a Comment

One of the questions we hear in our shop is “how often do I need to change my automotive brakes?”  If you are asking the same question, here are a few things to consider.

It is very important to determine the condition of your brake pads.  Brake pads typically come with a warranty, sometimes a lifetime warranty, but more commonly, it will be a warranty based on mileage, such as a 10,000 mile warranty.  A lifetime warranty isn’t meant to last a car’s lifetime.  Automotive part manufacturers use this terminology because brake pads do last a long time, but most car owners will trade in a car and purchase a new one long before their brake pads need to be replaced.  Regardless of how you say it, it’s important to listen to your car instead.  When you apply the brakes, you can hear the sounds of a worn brake pad.  If you hear a grinding noise or a squeak, it is time to replace the brake pads, regardless of the mileage.

The condition of the brake rotors also needs to be determined.  Automotive brake rotors, or brake discs, are what your vehicle’s brake pads clamp down on and stop the wheels from spinning.  Similar to brake pads, there are different types of rotors.  The type of rotor used depends on your car and your driving needs.

Unlike brake pads, rotors do not need to be changed on a regular basis, and should last indefinitely,  if you provide regular maintenance routines on your automobile.  Rotors will be damaged if you allow your brake pads to wear down and drive without the use of pads for an extended period of time.  The grinding noise you begin to hear from the brake pads is a sign that the screws in the base of the brake pads are grinding into the groove of your rotor.  The longer you allow it to continue to grind, the greater your chance of having to replace your rotors.

If you want to keep your automotive brakes in top condition, have them checked and replaced on a regular basis.

Creative Ways to Winterize A Car

by Leave a Comment

During these difficult economic times and with the holidays approaching, we are all looking for ways to save money.  We have put together some creative ways to winterize a car using common household items that most of us have around the house.  Because we don’t have to buy specialty items, this saves us money!

Using petroleum jelly on your battery terminal caps to stop battery corrosion is recommended by Michael Calkins, the manager of AAA’s Approved Auto Repair Program.  Simply remove the terminal caps and clean any existing corrosion off with a wire brush, then coat the terminals with petroleum jelly.  The jelly forms an airtight seal that wards off salt, slush and mud, all of which cause corrosion on the battery terminals.

Winter driving here in Colorado means snow one day, slush and mud the next.  This can play havoc on our cars and our headlights.  To keep your headlights doing their job, clean them with soap and water,  and then apply a nonabrasive car wax using a soft cloth.  The wax is water-repellent and leaves a barrier that keeps dirt from building up.  It’s recommended to do this once a month.

Have you ever gone out to start your car in the morning and not been able to get the door open because it is frozen shut?  Here is a creative way to prevent this.  Coat the rubber door seals with cooking-oil spray.  It repels the water that would otherwise collect on the rubber seals and freeze, causing the doors to be frozen shut.

Another problem that occurs during the winter is frost accumulating on the inside of our windows, obstructing our view and increasing our chances of having an accident.  A creative way to “winterize” your windows is to dissolve 2 teaspoons of salt in a gallon of water and wipe the inside of the windows and windshield with this mixture.  As the mixture dries, it leaves an invisible layer of salt-which has a low freezing temperature, and will help keep frost from forming on the windows.  This lasts for a month or more.  Don’t use this mixture on the outside of your car, the salt can cause corrosion to the exposed metal.

If you’re one of the people who store a car during the winter months, there is a chance that rodents might try to build a nest in your engine.  A creative way to discourage these little pests from nibbling on wires and making a home in your engine is to tape a peppermint tea bag, away from moving parts, to the engine.  The minty scent will repel rodents and keep them away through the winter.

If you try any of these creative ways to winterize a car, we would like to know how they worked for you.  We appreciate the feedback.

Why Is A Car Oil Filter Important?

by Leave a Comment

There are many times in our business that we meet customers who don’t understand why a car oil filter is important.  Most of them recognize the importance of quality oil but don’t realize how the oil and oil filter work together to keep their car running.  So why is a car oil filter important?

Oil filters have a very important function and if your oil filter has poor quality, it can shorten the life of your engine and cause other parts to fail as well.  This small part of your car’s lubrication system plays an important role in protecting your engine from premature wear.  All the moving parts in the engine need clean oil to properly lubricate them.  Tiny bits of metal chip off of various engine parts while it’s running.  If these bits of metal are allowed to recirculate through the oil, they could break off other bits of metal, which eventually will cause erosion in the engine.  A quality oil filter helps prevent this erosion from taking place.  The oil filter cleans the oil as it passes through the filter and prevents abrasive contaminants from damaging the parts in the engine.

It is very important to choose a high quality oil filter because the internal construction and quality of the filter has a huge effect on the life of your car’s engine.  Here at Express Care, we use a Wix oil filter.  Wix was patented in 1954 and has been at the forefront of oil filter technology and performance for passenger cars, trucks, buses and off-road vehicles ever since.

One of the standards used to determine the quality of an oil filter is called filtration efficiency or particle size retention.  Particle size retention is the measure of how well a filter can retain particles of various sizes.  Wix has developed optimum filtration efficiency in their filters.  They are able to trap and hold essentially all the particles larger than 25 microns (a human hair measures about 70 microns in diameter.)  These filters can also capture a high percentage of even smaller particles.

Another standard that a quality filter must meet is dirt-holding capacity.  This is the amount of contaminants that can be removed and held by the filter until the filter no longer works.  The capacity of Wix filters is much larger than the minimum requirements that are specified by vehicle manufacturers for a regular oil change interval.

Hopefully these facts help you understand why a car oil filter is important.  A quality oil filter and quality motor oil work together to help our cars run more efficiently.

Synthetic vs. Conventional Oil

by Leave a Comment

During these times when we are dealing with the economic crunch as well as concerns over the environment, the answer to a common question has even more significance.  Synthetic vs. conventional oil, which is better?

Conventional oil comes from crude oil that is pumped out of the ground.  The crude oil is refined at an oil refinery and becomes the base stock for conventional oil.  Even though it goes through a refining process, conventional oil still contains small amounts of contaminants that can’t be removed.  Unlike conventional oil, synthetic oils are made through chemical reactions.  Even though they are considered “artificial”, synthetic oils still have the same natural ingredients found in “real” oil, but these ingredients are recombined like a Lego set to create the characteristics desired.  These oils are purer and cleaner, custom designed to provide the “ideal” lubrication. Typically, the best synthetic oils use a combination of up to three different synthetic base fluids.

Because of the higher purity properties of synthetic oil, it can stand up to heat and withstand colder temperatures much better than conventional oil.  This is a huge advantage when you first start your car in the cold weather.

Both synthetic and conventional oil have additives to help prevent sludge and deposit build-up, but synthetic oil also has performance additives that provide superior protection for the life of your engine and in extreme driving conditions such as extremely cold or hot temperatures.

Synthetic oil flows easier in colder weather, so if you live in an area where it gets really cold in the winter, synthetic might be the better choice for you.

Because synthetic oil doesn’t break down as readily as conventional oil, there will be longer intervals between oil changes.  Synthetics can last almost three times longer than conventional oil, but still not forever,  as some people may think.  Eventually the additives in the synthetic will break down just like in the conventional oil and it will need to be changed.

The higher cost of synthetic oil has been a major deterrent for some people, but the fact that they extend drain intervals, provide better fuel economy and reduce engine wear, can offset the cost and make them more economical than you might think.

Take a look at your vehicle’s owner’s manual and see what the recommendations are and then come in and see us or give us a call at (303) 691-2760

Car Maintenance Checklist

by Leave a Comment

It’s hard to believe that summer has passed, it’s now September, the leaves are changing and it’s time to get our car ready for the changing weather!  This is the perfect time of year to go over your car maintenance checklist and make sure that your car is prepared for the coming winter.

  1. If you haven’t had the oil in the engine of your car changed recently, now is the time to have it serviced.  Regular oil changes are very important in your car maintenance.  Having clean oil in the engine helps to keep your car running smoothly.
  2. Battery Service–  The cables and terminals on your car battery should be thoroughly inspected for wear or damage.  The battery fluid should also be checked along with the batteries ability to hold a charge.  Colder weather can really deplete the battery.  If you’ve had the same battery for 4 years or more, you might want to think seriously about having it replaced.
  3. Check Tires– Your tires should be checked to make sure they are in good condition and will provide the traction you’ll need in the winter months.  Checking for proper tire pressure is another step on our car maintenance checklist.  In some of the newer cars, the tire pressure sensors can be triggered by the colder temperatures.  So if your car’s sensors have alerted you, have the tire pressure checked, so you’re sure the tires have the correct pressure they need.
  4. Replace Windshield Wiper Blades– Proper car maintenance includes replacing worn out wiper blades and refilling windshield washer fluid in the washer reservoir.  You might want to use snow blades during the winter months, they are designed for better snow removal.   Please don’t put plain water into your windshield washer reservoir!  It will freeze and crack the reservoir.
  5. Cooling System Flush–  Your car’s cooling system needs maintenance.  Not only does it keep the engine from overheating but it also keeps it from freezing.  It’s important to have the system flushed and replaced with fresh coolant.
  6. Have Your Brakes Checked-There is nothing more frightening than trying to bring your car to a stop in bad weather and the brakes don’t do their job.  If you haven’t had your brakes checked in the last six months, now is the time to have it done.

Before you know it, the leaves will be off the trees, and the snow will be falling.  Don’t get caught off-guard,  complete your car maintenance checklist today.  Let us help you with all of your Denver Auto Repair needs, you can trust Express Car Care.  Call (303) 691-2760 or stop by our shop today.

Auto Repair Cost

by Leave a Comment

In these tough economic times, none of us want to pay more for auto repair than necessary.  None of us wants to walk out of the shop holding an empty wallet!  That being said, we’re still left with the question, how much should auto repair cost?

When you drive your car into an auto repair shop for some needed repairs, the cost of those repairs are determined by several factors.  The make, model, and the year the vehicle was manufactured will be one of the first things that the mechanic will look at and has a significant  affect on how much the repair will cost.  Most of the time, European and foreign cars like Audi, Volkswagen, Mercedes, and BMW are more expensive to repair than domestic cars.  The parts on foreign cars almost always cost more than domestic car parts,which raises the auto repair cost.  Foreign cars and some domestic cars have engine designs that make their parts more difficult for your mechanic to access, this will also have an affect on the cost.

The type of auto repair needed will determine auto repair cost.  If your car needs a new part rather than a repair on an existing one, than the cost of the new part will be factored into the price.  Some repairs cost more because the replacement parts are more expensive.

Auto repair cost is also determined by labor rates.  The average independent auto repair shop has a labor rate between $90-$130 per hour.  If you take your vehicle to a dealership for repair, their labor rate will most likely be higher.  Dealerships usually charge more than independent repair shops because they have higher overhead costs to cover.  The labor charged is based on a standard “flat rate” and is usually the most expensive item on the bill.  The labor time required to perform a certain task varies depending on accessibility of parts, the degree of difficulty of the job, and if special procedures or tools are required to complete the job.  All these factors are taken into account by a vehicle manufacturer in order to determine and publish the flat rate tables for various repair jobs.  Cars today are just as technical as a personal computer, and when they crash, they’re just as costly to repair.  So use this information to look for a trustworthy shop that will give you honest advice, quality service and a fair price.
