Compact Cars That Come Packed With Savings in Fuel Costs. Which One Should You Be Saving With?

By , January 16, 2010

With gas prices on the rise, a lot of people are trading in their SUV’s and buying smaller compact cars. This is a good choice for many people because, although they may be small and not luxurious at all, compact cars are great on gas and reputable automotive repair manuals are available. Three good compact cars that are on the market today are the Kia Spectra, the Toyota Corolla, or the Honda Civic. All three of these compact cars get great gas mileage and although they are small, they make great cars. If you’re ready to spend less at the gas pump, check out buying one of these cars, either new or used, and you won’t regret it.

 

The Honda Civic Repair Manual is a solid and the compact car that gets between 35-27 miles per gallon. If you’re looking to really save on gas, check out the hybrid model which most people say uses just about $10 a month in gas! Although this car isn’t fancy at all and is rather small, if you’re looking for something practical rather than luxurious, this car could be for you. Some people have complained about having transmission problems or electrical problems with their Honda Civic but there are also many people who would say it is a great car. If you’re looking for power, you would have to sacrifice that for the great fuel mileage that the Honda Civic gets. This car isn’t very powerful at all, and may not have a lot of added features for comfort, but it drives very well and if you like a small car, this is a good choice. Check out the Honda Civic if you’re looking for a great compact car that’s good on gas, or if you’re looking for great gas mileage check out the Honda Civic Hybrid which will get you even further for less money.

 

The Toyota Corolla Repair Manual is known for being very reliable. It is another car that is great on gas but is very small. If you are a very tall person or are looking for a lot of extra leg room, then the Toyota Corolla is definitely not for you. These cars are also very affordable and parts are easily accessible for this car so if it does happen to break on you, it won’t be very expensive to fix it. If you’re looking for something a little bit more comfortable you can also choose to buy a Corolla with added features such as leather seats and a moon roof to make your ride more comfortable, while still getting the great gas mileage that the Corolla offers. This car can get up to 40 miles per gallon while driving on the highway which makes it a smart, affordable choice!

 

Another option for a compact car manual on the market today is the Kia Spectra Chiltons Repair Manual. This car is also very small and not as powerful as some would like, but if you’re looking for a car that’s great on gas, this is another good option. The Kia Spectra is known for having a smooth ride and is a bit more passenger friendly than some other compact cars. If you are looking for something that’s going to be powerful at high speeds, this is not the car for you, however. The Kia Spectra is another great option for a compact car that gets great gas mileage.

 

So whether you’re sick of paying ridiculous gas prices and need something that is just better on gas, or are looking for something small and simple, these three cars are great options for you! Whether you choose the Honda Civic, the Toyota Corolla, or the Kia Spectra, you are sure to get something affordable that feels a lot more expensive than it really is.

Gas or Diesel – Fuel Gulping Monster or a Loud Smoking Dinosaur

By , December 22, 2009

In this article I’m going to discuss the properties of the diesel and gas engines, and compare them to each other. Specifically their usage in cars.

Looking at them from a distance both the gas and the diesel engine work in about the same way. Fuel manufactured from refined crude burns in the cylinder forcing the piston to move from the resulting pressure. The motion of the piston is transferred to the wheels through the crankshaft, the gearbox and through the transmission.

It’s when we look at the engines a little closer that we start to notice that there are differences. Difference in fuel economy, smell, vibration, expected age and price just to name a few.

The gas engine has an ignition system with high voltages, wiring and spark plugs. This is not needed in a diesel as it compresses the air n the cylinder until it’s hot enough to ignite the fuel when injected. In a gas engine the spark plug ignites the fuel/air mixture by sending a high voltage spark into it at the right time.

Another thing that separates the diesel from the gas engine is that gas engines adds the fuel vapor to the air in the intake manifold either through a carburetor or through fuel injection nozzles. The air/fuel mixture is then sucked into the cylinder to be burnt the next time the piston strikes.

The diesel on the other hand sucks clean air into the cylinder and then waits for the piston to compress the air as much as it will go. At this time when the air is compressed and hot enough to ignite the fuel, diesel is injected directly into the cylinder (or a small space connected to the cylinder) through high pressure nozzles. The fuel ignites instantly due to the high temperature in the cylinder.

The different fuel injection and combustion lets the diesel work more efficiently than a gasoline burner. That’s why a diesel has a better gas mileage than it’s gas powered counterpart.

This is not to say that a diesel is better. It’s different, it has drawbacks too. Diesel engines usually is harder to start in cold and freezing weather. If you remember it was compressed hot air that ignited the fuel. When it’s too cold outside the air will never become hot enough to ignite the fuel, and the engine won’t run.

To handle this diesels have something called glow plugs for handling cold start situations. Electrical power from the accumulator is used to preheat the glow plugs inside the cylinders before the engine is started. This way the hot glow plugs ignite the fuel when the air is not hot enough to do it. A couple of seconds after the engine has started it is usually hot enough to ignite the fuel without the help of the glow plugs and these are not used again until the next cold start.

This is one of the things that might bother you when having a diesel engine in the car. The glowing takes from a couple of second to half a minute and can easily lead to stress when in a hurry. You just have to wait until it’s ready or the car won’t start. On the other hand if the engine is well done the glowing does not take long and you soon get accustomed to it.

Lets for a second look at the practical differences between the diesel and the gas engine. The diesel engine is large and loud and it produces clouds of black strinking smoke when accelerating. It also has a sturdier construction due to the higher pressures it must handle and thus can often go twice as many miles as a gas engine during it’s lifetime. The sturdier construction also makes it more expensive when first bought.

The Gas Engine

  • More quiet that the diesel
  • Better acceleration and higher top speed
  • Uses an Ignition System with Spark Plugs to Light The Fuel
  • Adds fuel to the air before letting it into the cylinder
  • Not as sturdy as a diesel. Lower price but breaks down faster
  • Gas readily available everywhere
  • MPG is low compared to a diesel

Features of The Diesel Engine

  • The diesel engine is loud and has the sound of an agricultural machine or an 18 wheeler
  • Slow acceleration (get one with turbo charger, that helps)
  • Moderate top speeds but can easily reach the legal speed limit in most places
  • Glow plugs helps ignite the fuel when the engine is really cold
  • Lets clean air into the cylinder and injects the fuel later
  • Engine is simple and robust. High price tag but can run many miles
  • Emits black smoke when loading it (like a quick acceleration)
  • Easy to convert to using Eco fuel oils
  • Has a great gas mileage

If I where to give you advice on selecting either a gas or a diesel powered car I would tell you this: Get a diesel if you drive long trips and can live with the small nuisances of more noise and poor acceleration. Get a gas powered car if you drive less than average or if you just want the comfort at any price.
