Unleaded, Diesel, and Ethanol Fuel – What’s the Difference?


Unleaded, Diesel, and Ethanol Fuel – What’s the Difference?

When buying a vehicle, you will come across these terms – unleaded, diesel, and ethanol fuels. What are the dissimilarities between these? And what would happen if you used the wrong type of fuel in a vehicle? Here, Capital Pre-Owned Center discusses how unleaded, diesel, and ethanol fuel are different.

Unleaded Fuel
Sounds complicated? Unleaded fuel is simply gas or petrol. This is the most commonly used type of fuel in vehicles. The price of unleaded fuel fluctuates, but when compared to other kinds, this one is relatively cheaper. However, there's also the premium version of unleaded fuel, known as Premium petrol. This is the expensive stuff, and some vehicles run only on this costly variant. If you have been using normal petrol, you can use Premium gasoline in a car that requires unleaded fuel. Remember that premium gasoline can prolong your engine’s life.

Diesel is quite similar to regular gasoline in the way it is created – by distilling crude oil. However, there are very significant differences here, and vehicles that run on diesel cannot run on regular gasoline. Diesel-powered vehicles give \better mileage than vehicles that run on unleaded gasoline. However, diesel vehicles produce more emissions than any other type of fuel. But because these engines are much more efficient than others, they produce about 20% less pollutants.

Ethanol Fuel
Ethanol is the most environment-friendly fuel. The emissions produced by vehicles that run on ethanol are much fewer than any other type of vehicle. It also falls under the category of renewable energy, which means that it is found in abundance. It is sourced from corn, and since corn supplies are renewed every year, you can be sure that ethanol fuel will be around much longer than unleaded fuel or diesel. However, the prices of ethanol fuel vary, and sometimes, it can get more expensive than unleaded or Premium gasoline.

As far as efficiency is concerned, it isn't as economical, which means you will need to fill you tank more often. So is it possible to switch fuels in a tank? No. Simply because when you use the wrong type of fuel, it won't burn the way it should.
