If you’re in the market for a new truck, you’ve probably encountered the decision of a gasoline or diesel engine. It can be confusing to decide which is better for your drivetime needs, so our Orlando Toyota dealership is here to break down the main differences and explain both gasoline and diesel engines for you so you can make an educated decision when it comes time to sign the dotted line.

Gasoline engines vs diesel engines

First, let’s talk about how things work under the hood.

  • Gasoline engines use spark plugs to create a spark and start an internal combustion process that ignites the fuel to get your car up and running. Diesel engines, on the other hand, use extreme compression to generate enough heat to cause the necessary spark for combustion – these types of engines actually don’t even have spark plugs.
  • Diesel engines also have fewer parts in them, which means they’re usually a bit more reliable and don’t require as many repairs as a gasoline engine, which has a lot of moving parts in it to keep things running.
  • Diesel engines have the capacity to be a bit more fuel-efficient than gasoline engines because of their higher compression rates and different parts. This is good because diesel fuel tends to be more expensive than regular gasoline, and you’ll only have one grade to choose from (where if you’re pumping gasoline, you’ll typically find 3-4 grades to choose from that vary in price). So you may pay a bit more for diesel, but the engine uses it more efficiently than you’re used to.
  • If you’re worried about how green your drive time won’t be when you drive a diesel truck, don’t. True, these trucks were traditionally seen as loud and bad for the environment because of all of the emissions they released. However, as technology keeps evolving, they get cleaner and quieter with every passing iteration. They’re also a lot lighter in weight than they used to be, which means even better fuel efficiency.
  • You’ll also have access to more power when you drive a diesel vehicle. These engines can generate more horsepower and torque than traditional gasoline engines, and they don’t have to be huge to do so because of their high compression rates.

Which of these engine options is better for you?

So how do you decide between the two? Here are some pointers to help guide your decision.

  • If fuel costs concern you, diesel engines may cost a bit more to fill (as diesel fuel can be more expensive) but they’re extremely efficient and in the long run, will likely cost less to run.
  • If repair and maintenance costs are a concern, remember that diesel engines tend to be a bit more durable because they have fewer parts that need care.
  • Diesel vehicles are especially efficient on the highway, so if you put a lot of highway miles on your ride this may be the way to go.
  • Gasoline-powered vehicles are usually a bit less expensive than diesel vehicles when you shop.
