If you own two credit cards, changes are that you
will use one of them to pay for your gas. Gas credit
cards are now starting to shine. There are many
individuals who are planning to apply for a gas
card. Most cards are either issued by a leading
credit card company or by a major retailing gas
station.

Along with that, there are some of the gas credit
cards that give you a great deal like having
discounts on gases such as unleaded, premium, and
others. Gas credit cards also give you an
assurance to have more approved gas bonus.

If the credit card is approved, the owner of the
card will not only save money on gas, but he'll
also get an extra allowance for car equipment and
accessories. Gas cards can also help you save
a bundle on repairs as well.

Keep in mind that there are some things to consider
when you apply for a gas card. When you plan to
apply for a card, the conditions should always be
known. The benefits of the gas credit cards
available should also be studied and researched
in order to compare rates, features, and
benefits.

As the popularity of gas credit cards continue to
increase, so will the offers. Gas cards also
offer a positive effect for gasoline retailers as
well. The customer will also earn additional
incentives as well. If you plan to stick with
one brand of gas, this card can generate some of
the best rewards.

When looking for the best type of gasoline credit
card, the most important thing to do is review
the terms and conditions. The present status
of the card should also be reviewed in order to
avoid a bad credit record.

There are also several gas credit cards that will
give you extra rewards and point systems. What
this means, is that the card holder can earn
cash back on certain purchases. The more points
you get, the bigger product you can receive.

The ideal purpose of applying for gas credit cards
is to help eliminate the gas expenses. The
credit card should help you to have a deal with
gas expenses. Low interest premium cards can be
the best if you can maintain the proper balance.

The best thing about gasoline credit cards is the
fact that you don't have to pay for them now and
you can just pay later. Just don't forget to pay
the bill, as you could end up getting a bad credit
rating.

If you plan to use your truck for towing, value
good fuel economy and plan to put plenty of miles
on it, you may want a diesel. The price to buy
a diesel truck is really high, although they can
offer you a lot in return.

Below, you'll find the leading vehicle manufacturers
and what they offer you.

Dodge
The 2500 and 3500 Dodge Ram Heavy Duty trucks are
the newest 3/4 and 1 ton trucks on the road. Back
in 2002, the Ram didn't have enough power with
the 245 HP 9.5L. Dodge promised more powerful
engines for the 2500/3500 platform and they
delivered on that promise.

The new base engine is the 5.7L gasoline V-8
that's not only the most powerful engine of the
group at 345 HP but also revives the well known
and historical Hemi name.

Ford
Ford helped push the 3/4 ton and 1 ton truck
market to where it is today when it introduced
it's international engineered power stroke
diesel back in 1994. Before 1994, these diesels
were poorly built and no match for the big
inch gasoline engines.

From 1994 to 2002, over 70% of super duty Fords
were sold with the optional 7.3L V-8 diesel
engine. This engine helped to put Ford among
the leaders in diesel trucks, as they had more
than they needed to dominate the market.

Chevrolet/GMC
The GM 2500/3500 twins Silverado HD and Sierra
HD both come standard with GM's 6.0L gas engine
V-8. This engine is ideal for 3/4 ton trucks
where towing isn't a concern. The upgrades
start with the 8.1L gas V-8 that's based on
Chevrolet's venerable big block engine.

Over the years, diesel trucks have proven to be
effecient with mileage, great for towing, and
easy on maintenance. Unlike gas engines, diesel
engines do not have spark plugs, which means
you won't need to get them tuned up near as
much as gasoline engines.

For those who like to haul heavy loads on a
frequent basis, diesel is the way to go. You
can get quite a few miles per gallon, and
diesel trucks are built to go 250,000 miles or
more before the engine needs to be rebuit,
making them a purchase that is more than worth
your money.

One ideal and promising way to boost the fuel
economy of gas engines is to add hydrogen to the
fuel/air mixture in the engine. Since hydrogen
isn't available at the local gas station, selling
a hydrogen boosted gas engine wasn't on the list
of engines – until now.

Lack of emission
A major cost and environmental advantage to hydrogen
boosted gas engines are low amounts of NOx emission
gas, which will completely eliminate the need for
external NOx emissions control. Currently, NOx
emissions control is a major cost problem for diesel
engines which use expensive traps to meet the
emission standards. Diesel engines particulate
emissions that must be collected by a filter that
should be changed periodically.

Hydrogen boosted engines on the other hand require
neither NOx or particulate control and require only
a low cost oxidation catalyst to control very small
amounts of exhaust which is formed mostly during
the engine starting up and warming up. Additional
cuts in emissions control requirements stem from
the engine's ability to use only the clean hydrogen
enriched charge during the cold start phase when
90% of emissions are generated in the emission test.

Cost
The hydrogen boost system is effectively a bolt
on technology that can be added to an existing
vehicle's engine compartment. According to those
developing the system, the cost of the system is
less than half of the added cost for diesel.

The future
Prototype hydrogen boosted engines are now be
installed in test SUV vehicles that have
sufficient space for the reformer and it's related
system. The start of long term road testing
for performance, reliability, and durability
information is planned for later on in the year
before the system goes further into development.

Four cylinder gasoline engines will likely be the
prime candidates for the technology as high gas
prices continue to generate competition among the
higher fuel economy models that seek MPG
leadership.

With gas prices getting higher and higher, hydrogen
boosted gas engines offer you the chance to get
more miles per gallon and not have to worry about
burning up all of your fuel. Instead of having to
go out and buy a diesel to conserve fuel, hydrogen
boosted units will help you preserve gas.

Even though they aren't available to buy right now,
they will be very soon. Many manufacturers are
looking into them, as they offer gasoline engines
something like never before. If you own a gas
powered vehicle and have thought of giving it up
to go diesel, you might want to think again – as
hydrogen boost units may change the world of gas
engines forever.

Fuel efficient mid size car – Toyota Prius hybrid
(60 mpg city and 51 mpg highway)
The Prius, unlike the Honda Insight, is capable of
carrying 5 people plus their gear. The Prius will
generate a total of 110 HP from its gasoline engine
and electric motor. The sleek shape to the Prius
has a low co-efficient drag although Toyota has
managed to do this with a larger, yet more driver
friendly vehicle than the Insight of Toyota.

Most efficient compact car – Honda Civic hybrid
(49 mpg city and 51 mpg highway)
With a reputation of being the cheapest hybrid in
North America, the Civic hybrid takes the great
design of the regular Civic and makes it a lot more
efficient. With an output of 110 HP, the Civic
hybrid is very competitive for the class.

Most efficient sub compact car – Volkswagon diesel
(37 mpg city and 44 mpg highway)
The Volkswagon Beetle diesel is ahead of even the
sub compact hybrids. Making 100 HP, the Beetle
diesel may not sound that powerful, although the
177 lb-foot of torque will put shame on every
other vehicle in the same class.

Most efficient station wagon – Pontiac and Toyota
(30 mpg city and 36 mpg highway)
The Pontiac Vibe and Toyota Matrix are both the
result of a joint venture of Toyota and General
Motors. Both vehicles come equipped with Toyota
engines, although a lot of the design and
engineering came from General Motors. Both the
Matrix and the Vibe are versatile with active
lifestyles. With a fuel efficient 1.8L 4 cylinder
that produces 126 HP, the Matrix and the Vibe
aren't going to win a street race although they
make up for it with smoothness, efficiency, and
refinement.

Most efficient large car – Hyundai Sonata
(24 mpg city and 34 mpg highway)
The Sonata is a major surprise, beating out very
stiff competition. The 2.4L 4 cylinder engine is
very smooth, responsive, and powerful. The
suspension however, is soft, and geared more
towards comfort than handling. This isn't a BMW,
although the build quality is great, clearly
demonstrating that Hyundai is no longer a second
rate manufacturer.

First of all, the diesel engine doesn't have the
parts that normally wear out or give problems. There
are no spark plugs, rotors, points, or distributor
caps like the garden tractor. There is no carburetor
either, that will gum up and be hard to start after
being stored for a long period of time. Diesel engines
can be stored for long periods of time and still start
right up.

Secondly, diesel engines in most tractors are water
cooled. This will allow the engine to run at a more
consistent and cooler temperature, which will extend
the life of the engine. The typical properly
maintained diesel engine can run thousands of hours
without breaking a sweat – and without having to be
rebuilt.

Diesel engines will also make more power. Even though
gasoline tractors may be a little quicker to start
with, they can't begin to match the power and raw
torque that diesel engines offer.

Another reason why diesel tractors are better than
gas is the available attachments. Most gasoline
tractors are equipped with a belly mower and don't
normally have a three point hitch. This will severely
limit the type of implements that you can use and
also limit the tractors expandability.

Most blades and scoop implements won't work with a
gasoline tractor. The drive train will also limit
the type of implement you can use with a garden
tractor. The typical gasoline garden tractor is
belt driven, while a belt drive won't pull as much
load as a diesel powered tractor. You would probably
not be able to use a box blade or tiller either
with the average gasoline powered tractor.

As the demand for vehicles grew, the demand for
fuel grew as well. Other actions and events have
played into the equation as well, resulting in
the rising costs of fuel. Fuel is something we
all need to run our vehicles, as we wouldn't be
able to go anywhere without it.

As you may know, a majority of the gas we get at
local gas stations comes from overseas, primarily
the Middle East. Therefore, we have to pay taxes
and such on the gas we use, which pays for the
gas as well as the shipping. If we got our gas
from within the United States, one can't help
but wonder whether or not the prices would indeed
be lower.

Diesel on the other hand, has always managed
to keep a price lower than gas. Diesel comes
from within the United States, so the prices are
of course going to be lower. The only problem
associated with diesel fuel is locating it, as
many gas stations don't sell it.

When it comes to the choice between the two,
diesel fuel is obviously cheaper to buy. Gas is
in supply more, which means that you can find
it almost anywhere. If you own a gasoline
vehicle, you obviously don't want to put diesel
in it. If you own a diesel vehicle, then you
of course wouldn't want to put gas in it either.

However, there are some motorists that still
complain about the engine's weak power, especially
when accelerating from a full stop. What you
may not be aware of is the fact that a diesel
engine can be tweaked to give more power without
harming the fuel economy.

Diesel engines use air compression to create
combustion versus the fuel/air mixture that is
required by gas engines. This attribute means
that diesel engines don't require spark plugs
and therefore don't need to be tuned up.

Diesel fuel has a much high fuel density than
gas, which results in fuel economy increases
of 20 – 30% over gasoline powered vehicles.

Diesel engines are also cheaper to maintain as
they have less parts than that of a gasoline
powered engine. The life span of a diesel
engine is also much longer.

If you're looking for torque, for pulling a
boat or other equipment, then the diesel
engine has the supreme advantage. Diesel
engines are surely slower, especially when
starting from a dead stop, although when you
climb hills or go over bridges, the diesel
engine is surely up to the task.

With trucks, diesel is normally the leader
over gas engines in terms of performance and
miles per gallon. Diesel trucks will get
more miles than gas trucks, and the price for
diesel is a bit cheaper than gas these days.
And with gas prices on the rise, diesel will
continue to dominate for a long time to come.

In diesel engines, air and fuel are both infused into
the engine at different stages, as opposed to gas
where a mixture of air and gas are introduced. The
fuel is injected into the diesel using an injector
where in a gas engine, a carburetor is used for this
very purpose.

With gas engines, fuel and air are sent into the
engine at the same time, then compressed. The air
and fuel mixture will limit fuel compression, and
thereby hence the overall efficiency. Diesel engines
only compress air, and the resulting ratio can be
much higher.

Advantages
Diesel engines are much more efficient and
preferable as compared to gas engines due to the
following reasons:
1. Diesel engines have overcome the several
disadvantages of earlier models that featured higher
noise and maintenance costs. Now, they are quiet
and require less regular maintenance when compared
with gas engines of a similar size.
2. Diesel engines are more rugged and reliable.
3. There is no sparking at all as the fuel
ignites. The absence of spark plubs or spark
wires also helps to lower maintenance cost.
4. The fuel cost produced is 30 – 50 percent
lower than gas engine fuel prices.
5. Gas burns hotter than diesel, and
therefore they have a shorter life span when they
are compared with diesel engines.

Diesel engines that are naturally aspirated are far
more massive than gasoline engines of the same power
for two reasons. First, it takes a larger capacity
diesel engine than a gas engine to produce the same
amount of power. Essentially, this is because the
diesel can't operate as quickly. The rev limit is
slower, because getting the correct fuel to air ratio
into a diesel engine fast enough is more difficult
than a gas engine. The second reason is due to the
fact that a diesel engine needs to be stronger to
withstand the higher combustion pressure needed for
ignition.

Diesel engines also produce very little carbon
monoxide as they burn the fuel in excess air except
at full loading capacity, where a full quantity of
fuel is injected per cycle. They can however,
produce a black soot from the exhaust, which consists
of unburned carbon compounds.

Often times, this is caused by worn injectors, which
don't atomize the fuel sufficiently enough, or a
faulty management system that allows more fuel to be
injected that can then be burned with the available
air.

For commercial use that requires towing, diesel
engines tend to have more desirable torque. Diesel
engines tend to have their torque peak quite low
in their speed range which provides smoother control
over heavy loads when starting from rest, crucially
allowing the engine to be given higher loads at low
speeds than a gas engine.

The lack of an electrical ignition system in diesel
engines improves the reliability. The high durability
of diesel engines is also due to the overbuilt
nature as well as the combustion cycle, which will
create a less violent change in pressure when
compared to a gasoline type spark ignition engine.
Diesel fuel is also a better lubricant than gasoline,
so it is less harmful to the oil film on piston
rings and cylinder bores – making it routine for
diesel engines to go 250,000 miles or more without
having to be rebuilt.

For several reasons, diesel proves to be better than
spark engine ignition. Diesel engines last a lot
longer, they offer more torque, and they are also
more reliable. They are also more expensive as well,
although you get what you pay for. If you have
never owned a diesel vehicle, you owe it to yourself
to see everything they offer you – and you'll find
yourself a very satisfied customer.

Gasoline ratios
Serious damage to gas engines can occur if you attempt
to run a high compression ratio with a low octane type
of fuel. Detonation is the ignition of the fuel due
to the high temperature caused by a high compression
ratio that is developed by design. The fuel is
ignited prior to the spark of the plugs that result
in a rapid, yet uncontrolled burning.

Diesel ratios
Keep in mind, the diesel is a heat engine, using heat
developed from the compression of air. High compression
ratios are possible since the air is compressed. The
hot compressed air is sufficient to ignite the diesel
fuel when it's finally injected near the top of the
compression stroke.

Diesel engines
Fuel and air in the design of diesel engines are not
premixed outside of the cylinder. Air is taken into
the cylinder through the intake valve and then
compressed to make heat. The diesel fuel is injected
near the top of the piston's stroke in an amount or
ratio that corresponds to the load on the engine.

Heavy duty
The higher compression ratio causes engineers to
design, and test the block, heads, head bolts,
crackshaft, connecting rods, rod bolts, pistons,
piston pins, etc., with a greater range of structural
capacity. To put it in other terms, diesels are
heavier than gasoline engines.

Gasoline
Deciding on gas and diesel can be tough, although
there are several reasons why you should use diesel.
1. Diesel engines produce twice the power
per gallon of fuel than gasoline.
2. A gallon of diesel is normally cheaper
than a gallon of gas.
3. Diesel fuel doesn't blow up. The fact
is, its hard to get diesel to burn at all.
4. Diesel engines will last four times
longer than gasoline engines.
5. Diesel fuel that is untreated will last
longer in storage than untreated gasoline.
6. Treated diesel fuel will last longer in
storage than treated gasoline.
7. Diesel fuel treatment will cost less
than gas treatment.
8. Spoiled diesel can be reconditioned to
refinery specifications, as spoiled gas can't.
9. Unmodified diesel engines can be ran on
vegetable oil.
