The sudden rise of gas prices has many Americans turning to mass transportation for the majority of their needs. In previously posted facts about hypermiling, the whole thing has more to do with driver discipline rather than the vehicle itself. With diesel going way above gas prices (which is quite unusual for gasoline is normally priced higher than diesel) big rig truckers and heavy machinery operators are feeling the crunch with many considering handing in the towel, for now that is. Heavy machinery that used to consume $400.00 of diesel a day now get the same amount for $700.00. Hybrids are alleviating some of the problems but not many can afford to purchase a newer more efficient vehicle. Besides, the environmental impact of green fuels (ethanol) are more than their weighted benefits.
People have formulated their own unique gas saving techniques such as collating all errands into one trip and taking it easy on the gas pedal. Gone are the days of hitting pedal to the metal and in with ease on the gas pedal for more fuel economy.
Cars have become more and more efficient as better engine technologies and lighter parts have been steadily finding its way into the market yet the sudden price increases have caught many off guard. Out with the V8’s and V6′ and in with the hybrids who may be the only option though a very costly one. Concepts like the one suggested by a previous post regarding a hybrid company which sells the car but leases the batteries might be a sound way to go. Gas prices would continue to go up as supply truly is dwindling, not because it is getting scarcer but because some of the biggest suppliers are experiencing conflicts like Iraq (some say it s the second largest producer of oil which is why many are interested in the troubled land). There might be no sight to an end to the high prices which affects all other goods for most rely on transportation at one time of the other.

The term describes a select group of driving aficionados who do out of this world driving (safely I hope) to squeeze every ounce of energy from every gallon of gasoline they have in their tanks. With gasoline hitting more than $3.00 a gallon, who wouldn’t? The trend has owners of hybrids and standard gas powered vehicles doing extreme driving practices such as trailing big-rigs (Tractor Trailers) to take advantage of their downdraft which creates suction in between the rig and your vehicle that you are actually pulled along by the rig in front of you. Another practice has people coasting as they are about to hit the stop light and many more. They have come up with unimaginable feats of getting up to or more that 100 MPG which is phenomenal with standard driving practices. Many have taken notice and many are turning into converts but many still question the safety of some of their practices or sometimes even the legality of doing such extreme maneuvers just to save every drop of gas.
They are a growing group that aims to educate people how they can lower their carbon footprints even while driving their cars. Many of these feats are possible only on hybrids but some nuts have been doing them in gas powered ones with equal results but I doubt that their lives should be placed on the line just to save on gas. Hybrids have a small gasoline engine that assists the electric motors during certain conditions that the computer can detect. Hybrids are designed or programmed to have the switching between gas and electric power under certain conditions to be automatic though most have switches that tells the car to stick with electric, gas or automatic propulsion. Hybrids have been getting reports of flat batteries and low charges due to these practices and doing some of these maneuvers on a gas powered vehicle can send you to the grave in no time due to braking power that is provided by the engine itself. It might be better to work with the designers of hybrids to have these changes to the way the car thinks included in the car’s computers rather than having to turn them off and do what you think is best for safety aspects are overlooked by some of these techniques and driving styles. And till they become standardized, I wouldn’t encourage drivers to do the same for as everybody does the same, who will you tail for everybody’s tailing everybody else, and all you’d end up with is a pile up of hybrids and trucks, you get the picture.
The drive to save on gasoline and thus lessen the dependency on oil is great. Global warming, high oil prices and many other environmental and man-made factors are having people take extreme measures just to save on gas. You might save every drop of it but endangering your life and the lives of others may not constitute such acts so do think twice about the implications.

Thanks to Mr. Luis Cruz for the suggestion!

In the never ending story of how GPS has allowed drivers and travelers alike to get to their destinations faster and easier, another addition to the saga of the errant GPS and their likewise errant drivers. As in previous posts regarding GPS and their ability to go wrong (extremely wrong) and give wrong directions drivers in the UK have had their common sense so to speak driven out of them as they drive into bridge overhangs and other structures which were not taken into consideration by the GPS mapping systems. The article came to my attention from Gadzooki which has a post dated on the 18th of April which shows hilarious yet serious statistics of drivers running into bridges like the ones shown in Mr. Bean cartoons and movies. These drivers trust their high-tech GPS navigation devices so much they forget to keep their eyes on the road and mind structures their vehicles may encounter. GPS has indeed made driving a pleasure by giving the right directions and even telling us when and where to go but it would also be a good idea to consider and include real-time traffic and positional data (not forgetting to take into consideration the location of low lying bridges and structures that may not accommodate the various types of vehicles that are on the road) which is already in some advanced high-price units.
The UK is a growing market for GPS and various gizmos and gadgets are coming to the public being sold as aides to UK drivers. The advantage is that the tons of camera’s in and around major cities allows UK traffic authorities to provide up to date traffic information where the driver can select alternate routes. The growing number of vehicles on the roads of Britain are becoming more and more of a problem which results in gridlock and traffic exclusion schemes to select areas that have provided some relief.
The Uk has also been able to produce one of the most powerful computers on earth named Hector which could be used to process vast amounts of data including traffic management and other tasks for the British Government. As technology progresses and heads into the future, we would be amazed at how far it has gone in the span of our lifetimes. We would also be assured of constant laughter when technology plus humans equals less common sense which makes the drive worth taking. Watch out for that BRIDGE!!!!!!!

Got a request from one of our readers regarding how to drive over steep inclines especially when stuck in traffic. This is kinda’ tricky but with practice you can conquer these inclines with relative ease. First, try to get to know the vehicle you are driving; are the brakes in good condition, does the handbrake function properly? I ask this for they would come in handy with a nice trick that can save you from rolling down as you are stuck in traffic later.

Try to gauge the steepness of the incline that you are going to drive through. Anything more than 10 degrees can send you rolling backwards uncontrollably without fast reflexes. Try to test the effectiveness of the brakes by going up a few meters, stepping on the pedals and see if the car still rolls backwards ( Keep your hand on the handbrake so you can stop if you do end up rolling backwards). If you are climbing without any traffic problem, it would be relatively easy for the car’s momentum will tend to get you over (try shifting to lower gears so you get more traction. If you are stuck in traffic going up, here’s a nifty trick you can try.

As you stop and press the brakes, engage the handbrake (I’ll advise you to keep your foot on the pedal so if the handbrake gives, your foot on the brake pedal prevents you from crashing into the vehicle behind you.). When traffic starts to move, give the vehicle in front of you a few meters clearance, depress the clutch and set the stick into first gear. Try getting the exact instance between the clutch engaging and releasing so you are set to roll as you release the handbrake. As you slowly release the clutch you would hear the engine straining a bit from the clutch engaging. As the engine tries to propel the car forward (which would be quite impossible for the handbrake is still engaged) release the handbrake slowly as you depress the gas pedal to get more power to the wheels(not too fast or you end up rear-ending the car in front). You should then begin to lurch forward allowing you to resume driving up.

The steeper the incline, the harder it would be to do this driving technique. Going down the same incline, use the engine for additional braking power (the process is aptly called engine braking which is quite complicated but necessary for economic engine operation) by selecting lower gears (1st and 2nd ) which has lower gear ratios that stops the vehicle aiding the brakes in the stopping of your vehicle. Others tend to use the clutch as a method of preventing the car from going backwards, which is not only dangerous for you can stall the engine suddenly sending you into trouble (it is also a sure way to burn out your clutch sending you for costly repairs to the clutch system and even the transmission).

Note: If you think the angle of the climb is greater than what your brakes can handle; do not continue driving up for you might not have enough braking power to stop in the hanging position sending you crashing into the vehicle behind you. Stay at the bottom till there is enough distance for the engine to get enough power over the top. Keep your hands on the handbrake so you can get additional braking power in case you do stall. Still not convinced if you can do the routine, try it on a steep driveway or somewhere traffic isn’t so hard like the bridge in the park away from traffic.

If you see steam from the engine compartment, you can turn off the engine and wait for it to cool down a bit before attempting to do anything under the hood. If there is no steam, you can open the hood and try to see if you can safely open the radiator cap. Only attempt to do this if you know how, for you can get seriously burned if there was steam or hot water under pressure to escape from a hastily removed radiator cap. Get a rag or disposable piece of clothing that would extend over the radiator cap and protect you from any rising steam or water. Twist the cap slowly paying attention to any steam which can indicate a dangerous pressure buildup in the system. If none is apparent, apply pressure on the cap while continuing to undo the cap slowly lifting the cap to release any pressure within the radiator. Once you get it opened, check to see if there is water or coolant in the radiator, adding accordingly if there is a lack thereof. Remember that you only add water to an overheating engine if it is still running, WHY?

If you turn the engine off, the engine’s various components begin to cool at different rates with the ones exposed to external air cooling quickly than those inside the engine. Killing the engine, stops the water pump from turning thus, preventing water from circulating through all the engine’s components equally to cool them properly. If you add water to the engine while it is off, the water cools the components it comes in contact first which can crack the engine block or other parts of the engine because of the different rates they are cooling. Hot metal expands, cool metals contract. Say the piston has cooled down due to less friction that occurred when you turned the engine off, the engine block which is more dense cools rapidly as you add water making it contract getting the piston stuck on the cylinder or bore resulting in a totally trashed engine.

An overheating engine can be caused by many factors but is mostly concerned with the engine’s cooling system that begins with the radiator, the hoses, water pump, the drive belts and the blowers or fans that cools the radiator. There are also varying methods to deal with such problems and here are some tips that you can add to your bag of tricks when your car does suffer from and overheat.

First, if you are driving and the temperature gauge begins to rise out of the normal, turn off the air conditioning to lower the strain on the engine and see if that remedies the problem. Get to a gas station to have it checked for it might be a sure sign of a deeper problem with respect to the engine’s cooling system. Driving on a blistering hot day in traffic with the air conditioner should not cause any concern for newer cars which still have new components but for older cars, that might be too much for the old-clunker to handle.

If that does not lower the temperature of the engine, drive to the nearest gas station for assistance. With some luck, they might have a mechanic on duty that can easily get you back on the road. If you just happen to have a back-up supply of water in the trunk, drive to the side of the road so you can safely diagnose the problem but “DO NOT TURN OFF THE ENGINE” if you intend to add water to the radiator. Any radiator fluid or water dripping from the hoses, engine or from any part of the cooling system can be a sure sign of a hose break or a leak in the many rubber plugs that covers unused hose ports on the engine.

Well, this might have to do more with the way the human body is designed and how much information we can process in a short period of time. Scientific data has shown that our actual active line of sight window (or the area of our vision which is fully analyzed and can be reacted to instantaneously) is limited to a few square inches in front of you. The rest is what is considered to be the peripheral vision area which we are aware of but do not have too much concentration on. Add to it the tunes playing on the radio, the shifting combination of the depressing the clutch and changing gears and you have a lot of information to handle for the human body to actually process (try this test to see if you are a safe distance from the car in front of you).

At 40 kmh, the average car (with stock brakes) can stop reliably in about 5 car lengths which translates to around 50 or 60 feet. This might sound quite far but this is true. Now back to the speed limit thingy, well these are placed due to many considerations such as the type of road surface, the amount of traffic that is to be expected, and the surmised fuel savings and so on and so forth. The one about speed in relation to fuel consumption is a good one, for at 80 kmh, your vehicle is running in balance with it’s weight and the momentum or it’s forward thrust that the engine is running efficiently burning only enough fuel to maintain that speed no more and no less. Now with most carburetor type vehicles that would be a good idea for these vehicles do not have computer brains like the newer models of cars which seem to have technology crammed into each and every corner.

The ECU (Electronic Control Unit) or computer of newer cars has the necessary programming to obtain information from a bank of sensors on the engine (temperature, idling speed, revolutions, amount of air entering the engine and many more) that allows it to adjust the performance of its parts to provide or attain maximum efficiency while maintaining fuel economy. Depressing the gas pedal on a carb-type vehicle and you pour gas into the engine even if it doesn’t need it sending some into the overflow line onto the street. Newer cars have recovery lines which send excess fuel back into the fuel delivery system or the gas tank for re-use. The speed limit is the determined safe speed to maintain necessary distances for braking allowing you enough time to react properly to the events that unfold such as in emergency cases in front of you. The human body reacts quite fast (in milliseconds actually which is the time your eyes see the information, sends it to the brain, processes it and comes up with the necessary response and sends the nerve impulses to the necessary muscles on your limbs for you to react) but at high speeds, that might not be enough. Why race down a street which is only a few blocks long? Just ease on the gas pedal and accelerate gradually for it not only saves fuel, it also saves on the wear and tear on other parts of the vehicle(brakes, suspension and other parts). Enjoy the trip and not the ride for it allows you to ponder about better things than the darned traffic jam ahead of you.

The brake system of your car is one of the most vital safety features that without which driving would be impossible. There are many things that can go wrong with your brakes and as preventive maintenance and regular inspection, it would be best to check on a few parts so you don’t get caught without brakes on the road.

Under the hood of any vehicle there is a container or reservoir as it is called that contains brake fluid and to most drivers, is the most known part of the brake system. Don’t keep this only topped off but make sure you use the right type of brake fluid (DOT 3 is the most common brake fluid grade used). The metal thing this reservoir sits on is called the Master cylinder which contains the pistons that forces the fluid from the reservoir into the brake lines (more on the other parts as we go on) to the wheel cylinders. Directly behind that is a metal drum like thing that is the brake booster which has a rubber gasket inside which multiplies the amount of force exerted by your foot on the pedal into immense pressures to stop your car. The brake fluid then goes through the brake lines to each wheel which are actually metal pipes with some rubber hoses in tight corners and moving areas to the wheel cylinders. The wheels all have individual cylinders or pistons that push the brake pads or drums to close and stop the vehicle. The parts the pads come in contact with are the rotors for disk brakes and drums for drum brakes.

More on the next post regarding maintenance and troubleshooting of the brake system.

You might be driving for a while now but you may not know how to read your dashboard gauges. Or are you even looking at them while driving? While it’s important to keep your eyes focused on the road so you might not hit other vehicles, pedestrians or objects, it’s also equally important to keep reading your gauges. Today’s most common gauges pre-installed to new model cars are the Speedometer, Fuel gauge, Temperature Guage and the Tachometer.

The Speedometer

This gauge obviously measures how fast your car is moving. Many says that this is the most frequently used gauge on your dashboard. Because the most common traffic violation is over-speeding, it’s been our practice to have a glance on it from time to time when driving on the freeway. Makes sense?

Older type speedometers work by the help of spinning cable connected to the transmission. The cable spins in proportion to how fast the speedometer gear inside the transmission rotates. The rotation serves as input to the meter by providing electromagnetic signals that makes the needle pointer to move. Modern speedometers use electronic sensors that measures wheel speed and sends it as input to the meter.

The Tachometer

Tachometer measures the revolution per minute (RPM) your engine makes. While over-revving is dangerous to your engine, the importance of this device comes in. Not all engines have the same maximum RPM. Ordinary cars can have a maximum of up to 4000 - 5000 RPM while racing cars can go up to 15000 or even higher. Racing cars have a special type of engine but this is a different story. Tachometer also helps you achieve the smoothest performance for your car. When you know the proper RPM you must have before each gear shift, I’m sure you’ll enjoy driving more. And another thing I noticed personally by considering proper RPM before each shift is that I maximize gas mileage.

Older type tachometer works exactly the same way as the speedometer. It has a cable with one end attached to the engine that rotates and send signal to the meter.

The Temperature Gauge

Car engines require certain amount of heat for best performance. When your engine is too cold, you may sometimes feel that your exhaust system is clogged and you’ll see lots of smoke coming out. You’ll also fell that your engine is a bit shaky. It also increases engine wears.

When it’s too hot, you won’t have the best performance either. Based from experience, it slows down my car and not only that, it seriously damaged the engine. So it’s better to monitor the temperature of your engine.

Common temperature gauges do not have the exact numbers in degrees on it. They only show Cold and Hot levels which means any degrees outside the hot or cold area is just good enough for your car. Too cold engine is not as problematic as too hot. If this happens oftentimes, consider checking these guidelines. Or might as well have your engine checked by a certified mechanic.

The Fuel Gauge

I would say, this gauge has the least importance. In fact, it’s the most inaccurate gauge of all. If you notice, after filling up your tank, you can see that the gauge is almost not moving but when it reaches below 3 quarts, it’s going down a bit faster. So it’s not accurate after all that you have consumed 1/4, is it?. Some gauges have the 3/4 mark a little closer to full to be ‘less inaccurate’. But I still don’t see its importance here. If you regularly fill up your fuel tank, it’s like you don’t need a fuel gauge anymore.

But I don’t say it’s not important at all. I saw its importance once when I drove quite long and when my gas run low, I can’t find a gasoline station nearby. So I keep on monitoring the gauge until I found one. I learned that the lowest mark doesn’t mean I’m out of gas. I still have some reserve. Though I don’t know how many liters I still got. And I felt so lucky that I was able to refill before the reserve run out.

Many people hit the road without knowing the basics. They go to driving school to learn, pass the test, get their license and go on driving. Many do not realize the danger that driving without the proper knowledge is crazy and irresponsible. We see it all over the news, a poor driver with a stalled vehicle, on the side of the road, struck by oncoming traffic because of the mere fact the other driver can’t see the broken down vehicle. Sad indeed, most of these tragedies end in fatalities that can be avoided if they knew that the two pieces of reflectorized triangles at the back of your car were placed there to save your life and possibly the life of the driver who can run you over.

For those who didn’t know they have two colors, one yellow and one red, why, well the yellow one is supposed to be placed about twenty feet farther than the red one which is supposed to be placed at least ten feet from the stalled vehicle. The yellow one attracts drivers of on-coming traffic that there is something wrong. just in case they don’t see the yellow one, the red one comes into view which means, “MY CAR’S BROKEN DOWN, GET OUT OF THE WAY!” They are now made of plastic which also serves a purpose, when on-coming traffic does not see them and runs them over, it will catch their attention and alert them that something is wrong ( I assure you that they would notice it) and hopefully get them to steer away from your car in time. Hopefully even if they run over the plastic triangles it catches their attention enough for them to get them to avoid hitting your stalled vehicle and injuring you both in the process.
