Gasoline vs. Diesel
You’re in the market for a new truck; you have an idea about what you want but not quite sure if you want a gasoline or a diesel engine. Well, gas and diesel engines are very similar yet different in quite a few ways.
At first glance, someone who doesn’t know much about either of the two engines might ask, “What’s the difference?” To the untrained eye they might look exactly alike, but don’t judge the engine by its exterior look.
Gas engines are mainly used by the individual in personal vehicles whereas diesels are very popular in the commercial and industrial fields. Diesel engines are used by the navy in their ships and by the army in their tanks and big trucks. Some of the main reasons for choosing this engine are

The continuing rotation of the crankshaft drives the piston back up, ready for the next cycle. The piston moves in a reciprocating motion, which is converted into circular motion of the crankshaft, which ultimately propels the car. Gas engines usually have about the same about of horsepower as they do torque. The diesel engine usually has twice as much torque as it does horsepower, thus it is the better hill climber and load carrier.
As you might have noticed, diesel engines have a harder time starting in cold weather compared to gas engines due to the fact that gas engines have an electrical started system. Gas engines rely on fuel, air and spark to ignite whereas diesel engines rely on heat and compression to initiate spontaneous combustion.
Some of the more obvious differences are the prices for fuel. As of now, March 2011, the price for diesel is significantly higher than gas. Gas is approaching the range of $3.40 per gallon to $3.70 per gallon (depending on what part of the country you’re in, it could be higher than that). Diesel, on the other hand, is nearing $4.00 per gallon and quickly rising. I remember 7 or 8 years ago when diesel was cheaper than gas, and gas was just above $1.00 per gallon.
Overall, I would say the diesel engine is the better of the two. Of course it all depends on the usage and perhaps the price of the vehicle but overall the diesel engine is more rugged and reliable, long-lasting, stronger, more efficient and requires less
