Diesel engines have improved over the years and are no longer followed by that puff of smoke that used to be a good indication you were operating the vehicle with diesel fuel. Technology has found a way to run a low-sulfur version that is known as a clean diesel. This also eliminates a lot of the soot smell that was apparent in the 1980's. Just like any other engine, the diesel has advantages and disadvantages over gasoline engines. Here are a few of those comparisons so you can choose which vehicle best suits your needs.
Diesel engines are 33% more efficient than gasoline engines, which mean you should get 30 miles per gallon for gasoline versus 40 miles per gallon for a diesel engine. It will also depend on which model you drive and how quickly automobile technology has achieved at a given time. Most diesel engines deliver better fuel economy.
Diesel engines do not need tune-ups because they do not have distributors or spark plugs.
Major repairs are usually not required because the diesel engines can withstand higher compression because they are built with a more sturdy framework. Many of the vehicles, such as a Mercedes can run in excess of 900,000 miles.
Diesel fuel costs just as much as gasoline, but in many cases it can cost more. Diesel fuel is used for heating oil, commercial trucks, and industrial or home generators. The demand for the diesel fuel will continue to rise and raise the price at the same time.
Diesel performance is a more enduring, stronger, but slower fuel versus gasoline engines.
Regular maintenance is required including changing the fuel, air, and oil filters regularly. Many of the diesel engines still have water separators that must be emptied manually. However, some of the newer engines do not require you to bleed the excess of water out of the system.
If maintenance is neglected or the fuel injection system has problems, you will probably have a larger bill because a diesel mechanic will be required due to the more advanced engine.
It comes down to which model or make of car you desire to purchase. Today's market has much to offer all generations of vehicles. If you purchase an older diesel engine, you may find it does not run as clean. However, you must be the one to weigh the advantages and disadvantages and purchase the vehicle that fits your lifestyle, like one from Western Avenue Nissan.
