Its estimated that eight out of every ten diesel engine failures are directly related to poor quality and contaminated fuel. The build up of contamination in the fuel systems and storage tanks can clog filters, thereby causing the engine to shut down, and damage to the engine to occur.

The number one reason for bad fuel is due to the increasing popularity of diesel power and the accompanying increased demand for more diesel fuel. Long ago, diesel fuel remained in the refinery storage tanks long enough to naturally seperate and begin to settle, allowing the clean fuel to be drawn apart. Now, with the demand getting higher than ever, the fuel is never stationary long enough to settle, and the suspended water and solids are passed on to the person buying the fuel - you.

The changes in refinery techniques is also a problem. In order to get more products, diesel fuel is being refined for more marginal portions of the crude barrel. This results in a lower grade product that is thicker and also contains a lot more contamination.

As time continues to pass and technology gets better and better, one can only hope that the quality of diesel fuel improves. As it stands now, the quality isn’t good at all. If you run diesel fuel, all you can basically hope for is that the fuel you are getting isn’t contaminated.

With more and more vehicle manufacturers realizing the potential of Hybrid vehicles, it wont be long before every car produced will be infused with the Hybrid technology. One of the newest in the batch hybrid car lineup is the Toyota Camry Hybrid, the third in Toyota’s Hybrid vehicles. The Camry hybrid boasts of a performance of a topnotch six-cylinder engine with the fuel economy of a four-cylinder engine. Although it is not as fuel efficient as the first Toyota hybrid, the Prius, the Camry hybrid is a whole lot better than the regular Camry.

Never to be left behind, giant Japanese car manufacture Honda, has also the Hybrid Accord and the Hybrid Civic. These two sedans offer what Hybrids are known for, less emission and less fuel consumption.

The Honda Accord Hybrid alone combines luxury and fuel efficiency that is truly environment friendly. Then there is the Civic Hybrid which continuously provides the true essence of hybrid technology. Its ingenious engineering has rightly earned it its Advanced Technology Partial Zero-Emission Vehicle (AT-PZEV) rating.

Joining the Hybrid car race in is General Motors second Hybrid vehicle, the Aura Hybrid sedan. This will be competing with other high-end hybrid cars such as the Toyota Camry Hybrid and the Honda Accord Hybrid. Sporting a V6 engine as well, the Aura Green Line is dedicated to providing utmost engine power with minimal gas consumption. Its engineers claim that it will be able to generate 20 percent savings in fuel economy over its conventional model.

Nissan has also announced that a Altima Hybrid will be offered and has offered test drives and a glimpse of its development vehicle. In a deal inked with Toyota, Nissan will be dedicating five years into the project with the Hybrid Technology developed by Toyota.

Rumored to be unveiling its first hybrid model, Volkswagen is said to be preparing a full-hybrid car for but it hasn’t disclosed yet which car model they will be infusing the technology. Latest rumors said that it would be on the Jetta for the upscale engine level or in the Passat for the four-cylinder class.
