Who would want to drive a car that gets worse fuel economy, a car that has less torque, and a car that is overall mediocre? Now, who would want to drive a car with much better fuel economy, higher torque, and a great, reliable engine? The most obvious choice is the latter, a car with a diesel engine. Diesel and petrol engines have been competing with each other since the 1930s. There is one main mechanical difference between these two engines; a gasoline engine ignites the gasoline with spark plugs, a kind of lighter, and the diesel engine ignites the diesel by compressing so much of it that it spontaneously combusts. Although there are some other types of engines now, such as hybrid or electric ones, diesel is still superior to these. My diesel engines are much simpler and more robust than petrol, hybrid or electric engines and run for many miles if maintenance is suggested. Because diesel engines work via compression rather than spark plugs or electrical components and batteries, they must be much simpler and more robust than a gasoline engine. This makes them able to withstand a lot of wear and tear. Cars.com, a reliable website for researching and buying cars, talks about maintaining a diesel engine: “Volkswagen, for example, says the oil and filter should be changed every 10,000 miles on its diesel models , as for the gas versions. However, the diesel engine program also includes changing the fuel filter every 20,000 miles.” Although gasoline engines do not have to change fuel filters as often as diesel engines, it is quite economical and easy to do. Diesel engines are very reliable and last a long time if taken care of. Their 2016 Golf TSI, the gasoline model, claims to get “25 mpg in the city and 37 mpg on the highway” for an average of 31 mpg, and their 2016 Golf TDI, the diesel model, claims to get “30 mpg in the city and 45 on the highway” for an average of 37.5 mpg. Furthermore, compared to electrics and hybrids, diesels are cheaper. EIA, the US Energy Information Administration reported: “On August 31, 2015, the average price of unleaded gasoline was $3,342 and the average price of diesel was $2,851 in California.” In California, the average driver between the ages of 16 and 65 who drives 13,476 miles in a Golf TDI instead of a Golf TSI saves more than $320 in fuel costs each year. Better miles per gallon, better fuel prices, and inexpensive than many hybrid and electric cars are three other benefits of owning a car that runs on a diesel engine
