Diesel vs. Gas: What’s the Difference?
Diesel and regular gasoline are the two most common fuel types used in vehicles today, though there are several variations of regular gasoline. Although they may seem similar, there are significant differences between the two.
Diesel
Diesel fuel is derived from crude oil and used primarily in heavy-duty vehicles, such as trucks and some passenger vehicles. It has a higher energy density than regular gasoline, meaning it provides more energy per unit of volume. This results in better fuel efficiency and increased torque for improved towing and hauling capabilities.
Additionally, diesel engines tend to have a longer lifespan than their gasoline counterparts, often resulting in lower maintenance costs over time. However, diesel vehicles can be more expensive upfront, and they may emit higher levels of nitrogen oxide and particulate matter, leading to stricter emissions regulations.
Gasoline
Gasoline is the more common fuel type used in most passenger vehicles, including sedans, SUVs, and light trucks. Gasoline engines are generally lighter and less expensive than diesel engines, making them a popular choice for everyday drivers. They also produce fewer emissions, which can contribute to a cleaner environment.
However, gasoline engines typically have lower fuel efficiency and less torque compared to diesel engines, making them less suitable for heavy-duty applications.
What are the three types of gasoline?
Gas is sold at three octane levels. Here are the advantages of each type of gasoline:
- Regular gas: This is the most commonly used gasoline, with an octane rating of about 87. It is suitable for most cars and provides good fuel efficiency. Regular gas is also the cheapest of the three types.
- Mid-grade gas: This type of gasoline has an octane rating of around 89-90 and is recommended for cars that require a slightly higher octane rating than regular gas. Using mid-grade gas can improve engine performance and fuel efficiency in these cars, but it is usually more expensive than regular gas.
- Premium gas: Premium gasoline has an octane rating of 91 or higher and is recommended for high-performance cars or those with turbocharged or supercharged engines. Premium gas provides the highest level of engine knock resistance and can help maximize engine performance. However, it is the most expensive of the three types of gasoline.
It’s important to note that using a higher octane gasoline than your car’s manufacturer recommends won’t improve performance or fuel efficiency and may even harm your engine. It’s always best to follow your car’s owner manual’s recommended gasoline type.
What’s Right for My Vehicle?
If you’re unsure what fuel your vehicle should take, be sure to ask us at your next Dodge service appointment or give us a call. If you accidentally put the wrong fuel in your vehicle, call us right away at 703-584-4600. Using the wrong fuel can cause serious issues.
Diesel engines rely on the fuel’s lubricating properties to prevent metal components from rubbing against each other and causing wear. Gasoline lacks these properties and can cause increased friction in an engine designed for diesel. Diesel is denser and more viscous, resulting in poor atomization and difficulty igniting in a gasoline engine. This may lead to misfires, reduced power output, and even stalling.
