Denver: Have You Considered Synthetic Oil?

by Leave a Comment

Denver: Have Your Considered Synthetic Oil?After recently seeing an ad for synthetic oil in Denver and realizing I didn’t know much about it.  I asked my helpful Express Car Care service adviser for some background.  Basically the inside of your engine gets really hot because of friction from the moving parts and from burning fuel.  Oil lubricates the moving parts to keep them from getting too hot.

The problem begins when oil turns to sludge, which is kind of a thick jelly.  Sludge clogs up little passages so that the oil can’t protect parts of the engine.  So the two best ways for Denver car owners to prevent sludge build-up is to always change their oil on schedule, and to use synthetic oil.

Synthetic oil is much more resistant to becoming sludge than conventional oil.  My service specialist says it has the added benefit of lasting longer than conventional oil so the recommended change interval can be slightly longer.

The thing I think is cool is that synthetic oil is more slippery than conventional oil.  Regular oil molecules are long chains where synthetic oil molecules are rounder.  It’s like which is more slippery, a pile of pencils or a pile of marbles?  This means that synthetic oil does a better job of lubricating my engine so it doesn’t get as hot, or wear out as fast.

Using synthetic oil can help Denver motorist improve engine performance and help their engine last longer.  I’m really glad my service adviser filled me in on synthetic oil.  Maybe you should consider synthetic oil for your next oil change.  Give us a call at Express Car Care and let us help.

Transmission Service: Smooth Shifting in Denver

Transmission Service: Smooth Shifting in DenverLet’s suppose you’re going to take some friends out on the boat for some water skiing on a beautiful lake for your last summer fling.  Of course, you get the boat ready, but what about your tow vehicle?

Think about it… heavy Denver traffic, hilly Colorado terrain.  Maybe some dirt roads-and it could be pretty hot.  And all the time you’ll be towing several thousand extra pounds around the Denver and surrounding areas.  That all adds up to a lot of severe strain on your transmission.  It’s going to be working overtime, spending more time in lower gears.  The internal transmission temperature is going to be much higher than normal.

Denver drivers need to make sure they have enough transmission fluid.  If it runs low, the transmission will run hotter and won’t have the protection it needs to cope with the added stress of towing.  Transmission fluid breaks down and gets dirty over time.  Whether your truck has an automatic or manual transmission, you need to have it serviced on schedule at Express Car Care to make sure it runs efficiently.

If you neglect your truck transmission too long, it can fail.  You really don’t want to pay for a major transmission repair even with the reasonable rates at Express Car Care.

Before you leave your home and head to the lake, bring your vehicle into Express Car Care for a trip inspection.  Your Express Car Care service technician will check your fluids, belts and hoses and let you know if your brakes are in good shape.   Don’t take a chance on spoiling an awesome vacation with a vehicle breakdown.

Express Car Care Tech Question on Your Fuel Pump

fuel-pumpExpress Car Care Tech Question:

I was driving on a local Denver freeway and my truck started sputtering and then the engine finally quit and I couldn’t get it started.  I was towed to a shop in Denver and found out I had to replace my fuel pump.

What could I have done to have saved my fuel pump?

Express Car Care Answer:

This is a tough one for Denver drivers because there isn’t any maintenance recommendations for fuel pumps.  They’re inside the fuel tank and you really can’t get to them without removing the tank.  But Denver motorists can do some things to make the fuel pumps job easier so they last a little longer.

A lot of vehicles are equipped with a fuel filter on their gas line.  This filters out dirt and rust from the gas tank before it gets to the engine.  Replacing a clogged fuel filter as recommended reduces the strain on your fuel pump.

Many newer vehicles driving around Denver have their fuel filter inside the fuel tank so it cannot be changed.  A good tip for car owners is to not run the fuel tank too low – this can cause fuel starvation that excessively wears the pump.  Also, you can’t go wrong using good quality gasoline with high levels of detergent.  This helps prevent the buildup of varnish and gum all along the fuel system.

A professional fuel system cleaning will clean fuel injectors and help remove carbon deposits from the valves and combustion chamber.

All these things improve fuel economy and increase performance for Denver car owners.  Ask your helpful Express Car Care service specialist if a fuel system cleaning is recommended.

Answers from Express Car Care: Tire Tread Depth

Question:

How can I tell when my tires are worn so much that they need to be replaced? Answers about Tire Tread Depth

Express Car Care Answer:

That is an important question for car owners.  As we discuss the matter, keep in mind that one of the essential jobs of your tire tread is to move water.  The channels in the tread act as passages for water to escape from underneath the tire.  The deeper the tread depth, the deeper the channel – and the more water that can be evacuated.

When enough water can’t be moved from underneath the tire, the tire can ride on the water – often called hydroplaning.  The tire is literally not contacting the road but rather is “floating” on the water, so there is little traction and the truck or car can slide.

So somewhere between a brand new tire and a bald tire lies the point at which the tire should be replaced.  Some governmental jurisdictions have a minimum tire tread depth requirement for auto owners – others do not.  So check the important laws where you live to learn the legal minimum.

Tire manufacturers are required to mold a tread wear bar into the tire.  This bar appears across the tread when the tire is worn down to 1.6mm ( 2/32 of an inch).  Drivers can easily do the quarter test ( they used to use a penny, but I guess inflation has affected everything).  Insert a quarter into one of the grooves with the caribou’s head pointing down.  If you can see the tip of the nose of this great northern animal, it is a sign of very worn treads.  That means it is high time to bid adieu to your tires.

Studies have shown, however, that there is an essential difference in stopping distances for auto owners in detrimental wet conditions with tires that have less wear.  For example, in controlled, wet conditions a vehicle with 3.18mm ( 4/32 of an inch) of tread traveling at expressway speeds was able to stop in about 85 feet ( 26 meters) less distance than the same car with tires with 1.6 mm ( 2/32 of an inch) of tread.  That could easily be the difference between a safe stop and hitting the vehicle in front of you.

New tires are a big ticket item for motorists so it’s natural to want to get as much value out of them as possible.  Just remember that a huge part of the value is the ability to stop safely in wet conditions.  You can speak with your Express Car Care technician for answers about tire replacement.

Air Conditioning Service

Air Conditioning ServiceLet’s talk about air conditioning service and repair issues for the Denver CO area.  Most of us Denver drivers don’t give our air conditioning a second thought as long as it’s making cold air.  But it’s a complex and expensive system that we should be thinking about before it starts blowing out hot air.

The refrigerant in the air conditioner contains a special oil that lubricates and cools the A/C parts.  When refrigerant leaks out, your air conditioner won’t make cold air, and the parts don’t have enough oil to protect them, so they wear out faster than they should.  This is the reason it’s important to service the air conditioner as recommended by your service center.

Replacing old refrigerant has another benefit:  refrigerant tends to gather moisture and become corrosive.  That causes leaks in the system which can be expensive to repair.  Fresh refrigerant protects the air conditioning components and keeps the system operating at peak efficiency so it doesn’t have to work as hard to keep you cool.

Even with regular service air conditioning parts can just wear out.  Normal wear and tear eventually gets to all moving parts.  Addressing early problems can save on more extensive repairs down the road.  For instance, a common failure is the clutch that turns the compressor on and off.  If you can take care of a bad A/C clutch when it first starts having problems you may be able to save the compressor.  Wait too long and you’ll have to replace both.

Check your owner’s manual or ask your service adviser at Express Car Care for service recommendations.  And if you’re hearing strange sounds when your air condition turns on, or if it just isn’t as cold as it used to be, have us give it the once over and see what it’ll take to keep you cool.

Did you know the Federal Environmental Protection Agency regulates the type of refrigerant you can use in your air conditioner?  Your service technicians are current on EPA rules for properly removing and disposing of used refrigerant, protecting the environment while keeping you cool.

Simple Answers from Express Car Care: Differential Service

by Leave a Comment

Differential ServiceQuestion:  What is a differential and why do Denver auto owners need to have it serviced?

Express Car Care Answer:

First of all – your vehicle has a differential.  If it’s a rear wheel drive, your differential is on the back.  If it’s a front wheel drive, your differential is built into your transaxle (transmission).  Denver auto owners with all wheel drive or four wheel drives will have differentials in the front and rear and maybe in between.

When you are steering through a turn at an intersection in town, the wheels on the outside of the truck or car have to spin faster than the inside wheels because they have to travel a slightly longer distance through the curve.  The differential compensates for these speed differences between the wheels.

Because it is part of the vital equipment that transfers engine power to the wheels, the differential is working pretty hard.  Differential fluid – an especially heavy-duty oil – cools, lubricates and protects the differential.  It needs to be replaced on a schedule to remove metal shavings and other contaminants.  Note:  If you have a front wheel drive vehicle, replacing your transmission fluid takes care of your differential service needs.

Differentials have become increasingly sophisticated for Denver auto owners.  Rather than the simple mechanical devices of “the good old days”, they are more complicated and may actually be part of the key computer controlled stability system.  This means they are more costly, so it pays for drivers to have them serviced on schedule at Express Car Care in Denver to avoid premature wear.  Talk to your helpful Express Car Care technician.  At Express Care, we provide quality automotice service including air condition service, transmission service and tire rotation.

Burning Brakes

by Leave a Comment

Burning BrakesSummer driving in Colorado can be very challenging at times.  It is so important that we don’t forget what we learned about driving downhill on our steep mountain roads.  Heavy commercial trucks aren’t the only drivers that will experience burning brakes if they’re not careful.  We all need to drive in such a way that we aren’t relying on our brakes too much.  I see it all the time coming home from a mountain trip.  Drivers with their brakes lights flashing on and off all the way down the mountain.  Whether you are a long-time mountain driver or have recently moved to Colorado, it’s important to know how to drive safely in the mountains.  Two things are especially critical:  brakes and tires.

The brakes on automatic transmission, late-models sedans weren’t built to handle the constant braking required on the 7 to 8 percent grades of mountain passes.  This is the time to use your car’s transmission to keep your speed low enough to maneuver the hairpin curves that you’ll encounter during mountain driving and prevent those burning brakes.  Before heading downhill, shift into second gear.  Don’t shift into neutral.

Using your transmission to avoid overheating your brakes on  winding mountain roads is smart, but also has its challenges.  In summer, driving in second gear, will cause your car’s engine to reach higher RPMs and hotter temperatures.  So if you haven’t checked your coolant level, or changed it since winter, you should do it now or you might overheat.

Another thing to consider is under-inflated tires.   This will give you less control on the road, and that is never a good idea, especially on a road with no guardrail and a thousand foot drop below.  So check your tire pressure before you leave home.  Also tires without tread can cause problems, especially if you’re towing a load.  The tread helps your tires grab the road and turn rather than spin.

Be aware of gravel and rocks on the road.  Gravel will cause you to slide and perhaps lose control.  Rocks large enough to cripple your car can roll onto the road, so stay alert and free from distractions while you’re driving.  Wildlife is also a concern when you’re driving in the Colorado mountains.  They can dart into traffic in a moments notice.  So have your brakes and tires checked out before you hit the road.

Express Car Care Tech Question on Your Check Engine LightExpress Car Care Tech Question:

I’m Alex.  My Check Engine Light came on in my truck and I’ve tried several things to make it go off but nothing has worked.  What should I do?

Express Car Care Answer:

Like Alex, most Denver car owners have experienced their check engine light coming on suddenly.  We get frustrated because we don’t know why.  Of course that’s perfectly understandable:  There are many reasons for the check engine light to come on – and there’s only one light.

Alex said she tried several things to get the light to go off – but it didn’t work.  Her goal was to get the light to turn off.  I would suggest that the goal should be to find out what caused the light to come on in the first place – and fix it.

You can search the internet and find millions of sites with tricks to get your truck engine light to turn off.  But what good does that do?  Whatever caused the light to come on is still wrong.  Not getting to the bottom of the problem can lead to other problems for Denver motorist – some minor and some more serious and expensive.

Your helpful Express Car Care service professional can get you started down the road of properly diagnosing the problem so you can have it repaired.  You can save yourself some time and frustration next time by having a professional diagnose the problem right away.

Simple Answers from Express Car Care in Denver: Severe Service

by Leave a Comment

Simple Answers About Severe ServiceQuestion:  What is a severe service maintenance schedule? 

Express Car Care Answer:

When I was a kid, Sunday meant having a bath, getting dressed for church and then hanging up my Sunday clothes as soon as we got home.  Mom didn’t have to wash those clothes but once a month.  Now Saturdays were a different story entirely, catching lizards, splash contests in mud puddles and crawling through the bushes with GI Joe.  Those clothes went straight into the laundry basket.  My Sunday clothes – easy use.  My Saturday clothes – hard use.  They required a different laundry schedule.

Severe service maintenance schedules are kind of like that for auto owners in Denver.  “Normal” driving has a regular schedule; “hard” driving has a severe service schedule.  Service intervals are shorter on the severe schedule.

Most owner’s manuals will describe severe service as:  Stop and go driving, short trips, low speed driving, extreme hot or cold, dusty conditions, carrying heavy loads, and towing.

For most Denver residents, some “severe” driving can be a part of their everyday routine.  You can meet with your helpful Express Car Care tech about how you drive around the Denver area and see if your routine is closer to the regular or severe definitions and then adjust your service intervals for things like oil changes, transmission and cooling system services so they fit your needs.  Give us a call and let us help.

Visual Blind Spots When Driving Around Denver

by Leave a Comment

Visual Blind Spots When Driving Around DenverWhen we drive on our Denver streets, we encounter blind spots.  We can greatly reduce our blind spots by properly adjusting our mirrors to give the widest coverage possible.  Make the adjustments to your vehicle before you start to drive.

First, adjust your rear view mirror to give the best possible view directly to the rear of your truck or other vehicle type.  You don’t need it to get a better view of either side of the car, the kids in the back seat or your dazzling smile.  The rear view mirror should look to the rear.

Next, lean your head until it almost touches the driver’s side window.  Adjust your side mirror so that you can just barely see the side of your car.

Now, lean your head to the middle of the car and adjust the outside mirror so that you can barely see the right side of the car.

With your vehicle mirrors adjusted this way, you’ll have maximum coverage.  Of course, driving in Denver is a dynamic process – things change every second.  So it’s wise to take a quick look to the side when passing to make sure that another vehicle hasn’t moved into an area you couldn’t see in your mirrors.

As you drive in the Denver area, avoid staying in other driver’s blind spots.  You can’t count on them to be watching their mirrors and looking out for you.  Pass large trucks and buses on the left whenever possible.  A trucks’ blind spot is much larger on the right.

Be attentive and wear your seat belts, and thank you for reading!
