Diesel Lawn Mowers

Diesel fuel is an alternative to gasoline, with its own advantages and disadvantages. Diesel is easier to refine from raw petroleum products than gasoline, and thus is often remarkably cheaper. In addition, diesel fuel contains almost 20 percent more energy per unit volume than gasoline does. However, diesel fuels have higher levels of toxic emissions than gasoline.

Working Toward a Better Diesel

In America, diesel fuels are primarily used for large trucks, as diesel-powered trucks have better fuel economy than gas-powered vehicles. However, American standards for diesel fuel are lower than other nations, and its use is limited because of the harmful emissions. This is changing, though, and the future looks better for diesel.

First of all, the U.S. is tightening restrictions on diesel quality. By 2006, it is hoped that all American diesel fuel will be low-emission, which is better for the environment. In addition, biodiesel fuels are being developed. These are diesel fuels that are refined from vegetable oils and have amazingly low emissions. Unfortunately, there are still some kinks in biodiesel fuel technology, and it may be several more years before they are widely available.

The future of diesel will mean little to the average commuter, as it is likely to have little impact on passenger vehicles. However, when it comes to larger vehicles--especially landscaping and farm equipment--diesel is both affordable and high-quality. Thus, a savvy shopper today will look ahead, and buy a diesel machine now to save tomorrow.
