Gas prices keep skyrocketing. But there is a lot a motorist can do to reduce fuel consumption. There are quite a few easy and inexpensive maintenance steps that can be taken to add miles to every gallon and save money.

Consumers waste millions of dollars everyday because of dirty oil, worn spark plugs, faulty thermostats, loose gas caps, underinflated tires, malfunctioning engine controls, poor wheel alignment, dirty air filters, and so on. These problems are basic and easy to take care of, yet still they are major causes of wasted fuel.

As they say, “a stitch in time saves nine”. With proper maintenance you can save a lot of fuel. Avoid gas vaporization by ensuring that your vehicle gas cap is not damaged, loose or missing. Your tires must be properly inflated otherwise it can cost you a few miles per gallon. Replace your spark plugs regularly to avoid misfiring and fuel wastage. Replace clogged air filters and improve gas mileage by as much as 10 percent.

Driving habits are another major contributor to poor fuel economy. Bad habits include exceeding speed limits, aggressive driving, excessive idling, carrying heavy items in vehicle, and the list goes on.

Fast driving in low gears can consume up to 45% more fuel than is needed. When traveling at highway speeds keep windows closed. Open windows reduce your mileage by 10%. You should drive steadily. Sudden changes in speed wastes fuel.

A lot of fuel can be wasted by prolonged warming up of the engine. You do not need to warm up engine for more than 45 seconds even on cold mornings. Starting and stopping your engine needlessly is another no-no. Avoid revving the engine, especially just before it is switched off.

You should also buy your gasoline carefully. Choose quality brands that provide greater economy. Buy your gasoline during the coolest times of the day. And never fill your gas tank to the top. The gas can slosh over and out of the tank.

Other fuel saving habits include avoiding rough roads, using straighter roads, regular tune-ups, inspection of suspension and chassis parts for misalignment, and removing snow tires during good weather seasons.

What is the definition of a classic car? One answer just might be: Mercedes Benz. With brilliant design and craftsmanship, Mercedes has always been in the top of their class, setting the standard for everyone else to follow.

Mercedes Benz is the oldest and arguably the most famous car brand in the entire world. Each car is built to reflect a specific design and performance philosophy although every car is recognizable as part of the Mercedes family. In this way, customers can trust that their vehicle will have the power, comfort, and handling that is synonymous with the Mercedes name.

Mercedes relies on target groups to maintain their admirable brand identity. Never veering from their original three-point philosophy, designers are continually dreaming up new models that represent the changing times and the prospect of a high tech future. As a result, Mercedes manages to bridge the gap between the past and the present, the traditional and the contemporary.

The latest Mercedes model is a stellar example of this modern mindset. The SLR McLaren is a wondrous achievement that has been called “the Greatest Car in the World” by Esquire Magazine. With a frame made from carbon fiber instead of the usual steel and a modern, stunning exterior design, this car heralds the next wave of automobiles and establishes that Mercedes Benz will lead us to the classic cars of the future.

The front seat is designed like a cockpit for a reason. When you drive an SLR McLaren, you are not just the driver - you’re the pilot. Mercedes has built you a road-craft for you to fly across the open air highway. With ample, leather seats and dual zone CFC-free automatic climate control, it’s better than your own private jet. Take it home. Take it anywhere. Wherever you go, Mercedes will send you in style.

In the last issue, we discuss about shaft seals and how liquid
is prevented from coming out from the pump housing even though
the shaft is rotating.

Mechanical Shaft Seals

Some mechanical seals are made to very fine tolerances. Damage
to mechanical seals and bearings can sometimes be cause by the
misalignment of pump shaft with the motor shaft.

Whenever some of the motors or driven machinery is dismantled
or even when the machines are not running smoothly, alignment
has to be done.

The purpose of alignment is to ensure that the centerline of
the motor rotor shaft coincides exactly with the centerline of
the driven machinery. Alignment is essential to ensure that the
machine runs smoothly with minimum vibration.

Provided the two shafts are not bent crooked, the two alignments
to be checked and adjusted are: Offset alignment and Angular
alignment.

Most alignments are rough alignment that can be done using
straight edge ruler and feeler gages. However for precision
alignment, the use of dial gauges with magnetic bases can be
used.

Offset Alignment

The radial alignment is checked using a straight edge ruler. By
placing the ruler across the coupling halves at the top, bottom
and both sides any gaps between the 2 coupling halves will
indicate that the shaft is offset slightly. The misalignment can
be corrected by shifting the motor or by putting shims to raise
up the motor or driven machine.

Angular alignment

By inserting a feeler gauge between the coupling faces and rotate
both coupling halves simultaneously we can check whether the
shafts have any angular displacement between them. The feeler
gauge readings at checked at four points on the shaft coupling.
Again the alignment is corrected by shimming or shifting the
machinery.

The motor and the driven machine should be bolted solidly to the
base after finalizing the alignment positions of the equipment.
