Conventional Oil vs. Synthetic Oil

by Leave a Comment

We are often asked, “which oil should I use, conventional or synthetic?”  This seems to be an unending debate, conventional oil vs. synthetic oil, but we will try to give you some facts that might make your decision a bit easier.

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 is goes through a refining process  conventional oil still contains small amounts of contaminants that can’t be removed.  Unlike conventional oil, synthetic oil base stock is created artificially or synthesized.  These oils are purer and are custom designed to provide the “ideal” lubrication.

Both conventional oil and synthetic 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.

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.

There are a few more advantages you get by using synthetic oil.  It flows easier in cold weather, so if you live where it gets really cold in the winter, you might want to use synthetic.

Also because synthetic oil doesn’t break down as quickly as conventional oil, there are longer intervals between oil changes.  Although some have thought that synthetics last forever, this is not the case.  Eventually the additives in the synthetic oil will break down like conventional oil and the oil 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, make them more economical than you might think.

Just as we need to do with all the information we receive, we need to decide what works best for us and our vehicle,  so look over  your owner’s manual, see what they recommend and then make your decision.

Transmission Problems

by Leave a Comment

As I get older I am even more aware of the small changes in my body and how they affect my abilities.  Just as our bodies give us clues that there might be something wrong, our car’s transmission will give us signs there might be problems.  I’ve listed here five clues that your car might have transmission problems. 

The easiest clue to help us spot possible transmission problems is leaking transmission fluid.  Automatic transmission fluid is essential to keep your car shifting properly.  Transmission fluid is bright red, clear and smells sweet when everything is working correctly.  Unlike motor oil, transmission oil isn’t burned up when it’s used, so if you are low on fluid, it has to be leaking somewhere.  It’s a good idea to have your transmission fluid checked at least twice a year, just to be safe.

Another clue there might be transmission problems is when you are starting your car.  A transmission in need of repair will have trouble turning over or may stutter before turning over.  If this is the case, it could be a simple problem like moisture in the electrical wires or a bigger problem in the transmission.  Have your mechanic test the electrical system and the transmission if you notice these clues.

Every car is built differently and emits different sounds while the engine is running, but usually clunking, whining or humming is a clue there might be problems.  If you notice a sound that you haven’t heard before, have your car checked out by a professional.  Just as your car shouldn’t make unusual noises it shouldn’t be grinding or shaking either!

Your car shouldn’t grind or shake when you start it or while it’s changing gears. Both are signs that your transmission needs attention.  If you notice anything besides a smooth transition between gears, then you might have transmission problems.

The check engine light is the quickest way  to alert you to any problems in your engine.  Most cars use electrical and computer systems to monitor the proper functioning of the transmission.  If the check engine light comes on, check if there are other clues to help you assess if the problems you’re having are related to your transmission.  If you’re in doubt, take your car to a trusted and qualified mechanic to determine whether or not your transmission is in need of service.

Fuel Injection Cleaning Service

by Leave a Comment

Maintaining our vehicles properly is the only way to ensure peak engine performance and good fuel economy.  Having a fuel injection cleaning service is sometimes overlooked but it is an important part of maintaining your car’s engine.

The fuel injector is a small engine part that injects fuel where it needs to go, at a rate that is best suited for your car.  When it’s in perfect condition, the fuel injector filters out debris that is not good for the engine and also allows the filtered fuel to be used by the engine correctly.  When fuel injectors are dirty, they can’t deliver the correct spray required for your car’s combustion, so your fuel economy and engine performance will suffer.  Fuel injectors get dirty over time because some chemicals in the gasoline don’t evaporate or get washed away and they leave deposits on the injectors. These deposits build up and if they aren’t removed they will clog the injectors.  If your car is misfiring or idles rough, it could be a sign it might need a fuel injection cleaning.

There are different ways of cleaning fuel injectors.  One is to add a fuel injector cleaner to a tank of gas every once in awhile to clean them.  Another way is to have the fuel injector removed, cleaned and serviced professionally.  This is the better method because as well as cleaning, you can also have repair work done on the injector if it’s needed.  It’s important to have your fuel injectors serviced once a year.  When you use an in-tank method of cleaning your injector you are unable to see the condition of the filters, O-rings and other parts of the injector.  All these parts wear out eventually and can cause problems if not replaced.  Also only using the in-tank method can damage parts of the injectors.  When you have a professional fuel injection cleaning service, your mechanic checks the filters, O-rings and other parts to see if they need to be replaced and then replace them if needed.  Though this method may be more expensive and time consuming, it is usually the best cleaning process.

Winterizing A Car

by Leave a Comment

We have all heard the saying “all good things must come to an end” and unfortunately this saying is true when it comes to the summer weather.  Summer weather is leaving and winter is on its way!  That means it is time for winterizing our car.  Because of our modern technology, winterizing a car isn’t the major hassle it once was, but it still needs to be done!  These are some simple steps to take for winterizing a car.

Have Your Car Serviced- The oil in your engine needs to be changed regularly to keep your car running smoothly, so if you haven’t had your oil changed, do it now.

Have Your Cooling System Flushed- Your car’s cooling system not only keeps the engine from overheating but also from freezing, so it’s important to flush the system and have it replaced with fresh coolant.

Have the Battery Serviced- Your battery cables, terminals, and fluid should be thoroughly inspected for any damage or wear.  It should also be checked to make sure it has the ability to hold a charge, so you are prepared for the colder weather.  If your battery is more than 4 1/2 years old, consider replacing it.

Replace the Windshield Wiper Blades– Your wiper blades should be replaced with snow blades and make sure there is windshield washer fluid in the windshield washer reservoir.  Don’t use plain water, it will freeze.

Have Your Tires Checked-Your tires should be checked to make sure they are in good condition for winter weather.  You may want to consider using snow tires during the winter months, they do a much better job than an all-weather tire in the snow.

Have Your Brakes Checked– There is nothing more frightening than trying to stop in bad weather and not having your brakes do their job.  If you haven’t had your brakes checked in the last six months, now is a great time to do it.

Those are the major steps that should be completed in winterizing a car but there are some small details you should do also.  Put together an emergency kit for your car with a blanket, gloves, ice scraper, a small snow shovel, flashlight and kitty litter ( for traction in snow).  Check the lights, heater and defroster to make sure they are working properly and have them repaired if not.  You should also keep your gas tank as full as possible to prevent moisture from freezing in the gas lines.

Car Maintenance Tips For Your Older Car

by Leave a Comment

I have an older car. ” What type of car maintenance tips can you offer to make sure my vehicle stays in top shape?” ” I’m not ready to jump into a new car, so I want to keep my older car in the best shape possible.”  We’re hearing a lot of this these days.  Instead of replacing a car every three to four years, people are pushing the window of ownership, and are choosing to keep their older cars an extra year or two.  Not only will it save  money on monthly payments, but it also can save  on insurance rates as well.

Keep a car maintenance log

Keep a small spiral notebook and pen in your glove compartment, and keep track of all of your car related maintenance.  You may also want to record your gas fill-ups and mileage, a reduction in mileage can be an early warning sign of a future problem.  Also use the same service location for all your car maintenance items-they will track your maintenance and be able to monitor potential problems along the way.  Keep your receipts from the services you have performed on your vehicle, they will help you remember what work you’ve already had done.

Buy gas at reputable service stations

Ask whether the gas you buy is filtered at the pump and if the station has a policy about changing the pump filter regularly.  Some stations don’t have pump filters, making you more vulnerable to dirty gasoline.  Other stations may not mix alcohol and fuel properly or water down their product.  Find a station you trust and stick to it.

Don’t fill up if you see the tanker

If you happen to see a gasoline tanker filling the tanks at your local gas station, come back another day or go to a different station.  As the station’s underground tanks are being filled, the turbulence can stir up sediment.  Sediment in your gas can clog fuel filters and fuel injectors, causing poor performance and possibly repairs.

Lighten up your key chain

Does your car key share a chain with a dozen or more other keys?  That’s a pretty heavy load hanging off the car key when it’s in the ignition.  The weight, combined with bouncing while you drive, can wear out the tumblers inside the ignition and eventually lead to ignition switch failure. To add years of service to your ignition switch, purchase a light weight key chain that allows you to separate your ignition key from the others.  Drive with only the ignition key in your ignition.  If your ignition key “sticks” when you try to turn on the car, it’s a warning that your ignition switch is about to fail.  Replace it before you get stranded.

Fix and fill your washer fluid tank

With Colorado’s variable weather patterns, you may notice a cracked washer fluid tank on an older car.  Fix immediately, and keep it filled with plenty of window washer fluid, especially on cold, slushy days.

Clean your car thoroughly

Clean your car inside and out.  While everyone likes a clean car on the outside, the inside is just as important.  Clean off the magnesium chloride from your wheel wells and undercarriage, which Colorado uses to keep the streets ice free in the snowy months.

Auto Repair Questions to Ask Your Repair Technician

by Leave a Comment

Today’s cars are more complicated than ever, using computers and sensors to run virtually everything within your car.  From navigational systems, to videos, and even WiFi connectivity, when something goes wrong, it can have a major impact on your daily life.

Your automobile is a big investment.  And with today’s increasing technology, even a small repair can be a big investment as well.  It’s important to find an auto repair technician you can trust.  Someone who will give you honest feedback on the condition of your vehicle, and what your options are.  Here are some questions to ask your repair technician before you leave your car:

  1. How safe will my car be?  Certain cars are more susceptible to theft and break-ins.  Will they keep your car safe and locked up if you have to leave it overnight?  Do they have an alarm system in place and a well lit area?
  2. How much experience do you have?  Review the credentials of your auto repair technician, as well as the qualifications of the company as a whole.  A company should stand behind their work, no matter what technician works on your car, and should guarantee the work they perform.
  3. What type of certification do you have?  Again, both the company and the technician should have certification to work on vehicle.  Find out if your auto technician is ASE certified or has comparable training.  Ask if mechanics have received updated training that supports the technological advances found in today’s cars.
  4. Is there a guarantee policy and what are the conditions under which it is implemented?  While every good mechanic strives to offer the best service possible, occasionally something may happen with the work performed.  Find out what the guarantee policy is.
  5. Do you have a web site, and do you post specials or discounts?  If there are discounts, is it necessary to clip coupons to receive the discounted price?

The better working relationship you have with your auto repair technician, the more you can rely on them to answer questions, and keep your car in top shape.  They are there as a resource for you, not simply to repair your car.  They build their business by being an expert, and sharing their expertise with you.  Just ask.

Oil Change Special

by Leave a Comment

Regular maintenance is a part of the life of your car.  If you do just a few things on a regular schedule, you can avoid larger problems down the road.

Regular Scheduled Oil Change

At the top of this important list of  regular maintenance services  is the oil change.

Changing your oil regularly prevents the formation of sludge.  Fresh oil is used within the engine to clean away dirt particles, keeping them from settling onto the engine.  With regular changes, the particles are removed before they can begin to cause a problem.

In the same manner you visit your doctor for a routine checkup once a year, the auto industry has recommended that once every 3,000 miles your car has an oil change.  These guidelines provide you with a regular interval, and helps extend the life of your engine.

Different dealers and auto repair shops offer different services when you purchase an oil change.  Here at Express Care, we offer our Express Care Full Service oil change.  This includes:

  • Draining used oil and refilling with motor oil.
  • Installing a new oil filter

Plus we check and fill the following:

  • Lubricate your vehicle
  • Transmission fluid
  • Power steering fluid
  • Battery water
  • Windshield washer fluid

  • Tire pressure

In these tough economic times, it’s so important that we take care of our vehicles properly so we don’t have to spend a lot of money to repair or replace them.

Transmission Troubleshooting

by Leave a Comment

Your transmission is the one piece of equipment that is multi-faceted.  It controls everything from shifting your car from gear to gear, to controlling how fast you are going.  While you may never change out a transmission or spend time learning how it works, there are some tips to help you with transmission troubleshooting, and knowing when its time to call in a mechanic.

While there are many pieces that make up a standard automatic transmission system, all transmissions have a few basic parts.

  • The bell housing, or metal case that sits underneath your car
  • The gears
  • The transmission fluid
  • A filter to keep the transmission operating properly

You’ll usually notice a problem with your transmission in one of two ways.  Either your car will simply stop, or it starts running roughly.  These two problems are generally caused by:

  • Low fluid level, which causes your car to shift poorly, and can eventually lead to transmission damage.
  • A leak within the system.  This is usually easy to spot because transmission fluid has a red tint.
  • A clogged filter, which limits the cars performance.

Because of the many parts associated with a transmission, and the specialized tools you’ll need for troubleshooting and fixing, it’s usually best to leave it  up to a professional.  A professional understands what can be causing the problem, and can usually spot the problem quickly.  They will test a variety of things before moving on to a rebuild or replacement.

Car Air Conditioning and Allergies

by Leave a Comment

If you suffer at all with seasonal allergies or asthma, you are more than likely very serious about trying to prevent triggering their symptoms.  You have probably followed all the recommended guidelines for reducing the risk of triggering your allergies.  You keep your windows and outside doors closed as much as possible.  You use air-conditioning to cool your home and avoid using window and attic fans during pollen season.  You avoid being outdoors in the early morning when the pollen is more prevalent and you keep your car windows rolled up and use your car air conditioning when driving.  But each time you enter your car and turn on the air conditioning, something very unpleasant happens.  Your eyes start to water and your nose starts running, then you begin to sneeze while your throat starts itching.  What is happening?!

Common allergens and irritants found inside the average car can make driving a real challenge for people who suffer with allergies.  Dust mites and mold can grow in cars and linger for long periods of time.  A car air conditioner doesn’t harbor mold because it is a sealed unit that outside air can’t penetrate.  But mold can grow in your air conditioner’s vents and the hoses that connect it.  This happens when moisture becomes trapped and can’t escape through the venting, like the  showers in our homes.  Mold loves humidity and thrives in moist conditions.  To help prevent mold in your car’s air conditioning vents, here are some steps to try.  As you near your destination, after running your air conditioning, switch your air conditioning system off and turn on the vent.  Do this at least two miles from your destination.  Turn the vent on high so there is a lot of air blowing through the vents.  The air won’t be as cool as it is when the air conditioning is on but it will dry out any moisture that might be trapped in your vents.  If you do this each time you use your air conditioning it will help prevent mold and pollens from accumulating and triggering your allergies.

If you practice these guidelines and still notice allergy problems when you are in your car, we offer a service here at Express Car Care, that can clean your car air conditioning so you can enjoy driving again.  Ask one of our service technicians for more information.

Differential Service

by Leave a Comment

Summer has arrived and for many of us that means we will be spending a lot of time in our cars.  We drive to sporting events, concerts, camping and fishing trips,  and some of us head to the mountains for a little off-roading!  But no matter how you spend your summer, you want your car to get you where you want to go!  To help you make that happen, we suggest you have your vehicle checked to  see if it’s  in need of a differential service.

Whether your vehicle is a front-wheel drive, rear-wheel drive, or four-wheel drive, it has a differential, maybe even two or three.  The differential is a special gear box located between the drive wheels of your car.  The differential allows the wheels to turn at different speeds while still providing power.  Without a differential, our tires would rub and hop along the pavement, instead of gliding smoothly during turns.  Rear wheel drive vehicles have a differential in back.  The majority of four-wheel drive trucks and SUVs will also have a similar differential on the front axle. But no matter where they are located, all of the engine’s power is routed through your car’s differentials.  In order to perform their purpose, they need to be properly lubricated.  You can accomplish this by having a differential service done regularly on your vehicle.

A differential service is simply having the used fluid drained and replacing it with clean fluid.  Neglecting to change the differential fluid can cause poor performance, premature wear, noise and even failure.  Replacing a differential assembly can cost as much as $1500, so don’t let that happen to you.

The benefits of having a differential service are numerous.  It removes metal shavings and other contaminants that naturally enter the differential during normal operation.  A differential service reduces heat levels inside the differential and protects against friction, rust and corrosion.  It extends the life of your differential and provides protection especially under extreme conditions.   To keep the expensive metal parts of your vehicle protected, it’s important to have the differential fluid checked and changed at recommended intervals.

The mileage interval for servicing your differential can vary according to the type of vehicle you drive, and how and where you drive it.  Check with your service adviser or your owner’s manual for recommendations.
