tow truck service falls churchGas v. diesel is a long-standing debate that has ruined more than a few family dinners. Each fuels’ faction is unwilling to concede to the other. Indisputably gasoline and diesel are the two most popular fuel choices on the American roadways, and both have their pros and cons. Today we will examine both and give you their biggest strength and weakness.




Gasoline engines make up 90% of the non-commercial vehicle market and there are certainly some strong reasons why. The first reason is due to fuel availability. Gas is easily accessible and cheaper than its diesel counterpart, which is the main reason why it is the choice for most passenger cars. Gas engines also offer owners more affordable and accessible replacement parts and service. The simplicity of a gas engine makes your car’s preventative maintenance easy, such as changing your own oil or replacing a spark plug. Cost is of massive importance to most vehicle owners, and for gasoline power plants, affordability is clearly a pro.


One drawback of gasoline is its lack of efficiency. Gasoline is said to be less dense than diesel which means it produces less power overall. Counterintuitively gas has a more violent reaction to air when ignited. The rapid expansion of gasoline fumes in the engine cylinder causes more wear and tear on gasoline engines in totality. This is why modern gasoline engines are known to run for up to 150,000 miles. That may seem like a lot of distance for one vehicle to cover but compared to diesel, durability is considered a con.

Diesel engines are what make the world go around. While gasoline corners the market for passenger vehicles, nearly everywhere else you look you will hear the distinct rumble of a diesel engine. Every high rise office building and human dwelling was constructed on the backs of diesel-powered. All of the food in your kitchen arrived at the supermarket in the trailer of a diesel-powered semi-truck. Diesel is preferred for these heavy-duty applications due to its incredible durability and efficiency.


Diesel fuel is energy-dense and thus at low RPM can produce massive amounts of power. This is ideal for trucks that are designed to trailer a heavy load. Additionally, because of its high output at low RPMs, diesel engines are not subjected to the abuse that gasoline engines often face. It is common to see diesel engines reach upwards of 300,000 miles and many semi-trucks reach over 1,000,000 miles! Their long shelf life means that diesel engines hold their value much better than gas engines.




Gas and diesel are great in their own ways. Gas offers an initial cost efficiency that diesel does not. Its cheap repair costs and functionality are why it is so common among class-e drivers. However, if utilized diesel can be equally as efficient in both commercial and non-commercial applications. Gasoline’s fuel cost savings and lower maintenance costs are front-loaded. Gas-powered vehicles will only last half as long with double the need for maintenance in comparison to diesel engines.


In a long-term view diesel is a clear winner for its durability, value, and fuel economy.
