The Difference Between Diesel 1 & Diesel 2

diesel 1 or 2If you find yourself needing diesel fuel but aren’t sure what the differences are between Diesel #1 and Diesel #2, then you came to the right place. While most people who will be utilizing these types of fuel will know which is right for their vehicle – there may be some who want to confirm before potentially wasting hundreds of dollars on fuel that won’t work, or worse, fuel that could damage their vehicles and equipment.

The Purpose of Diesel #1

Unlike the contrast between gasoline and diesel, choosing between Diesel #1 or Diesel #2 won’t necessarily break the bank or your vehicle. Diesel #1 has two main differences from Diesel #2. First, it burns hotter and faster, meaning you’ll need to fill up more frequently (compared to Diesel #2, but it’s still more efficient than gasoline). Second, Diesel #1 is thinner – which can make it a better choice for driving in cold temperatures or during the winter months.

Thinner diesel means it won’t become slow and sludge-like when the temperatures drop. This will allow it to move more freely throughout the engine. While most fuel pumps don’t regularly offer straight Diesel #1, many states that suffer through winter will offer a diesel mix that prevents diesel gelling.

Why You’d Want Diesel #2

When you head to fill up your diesel tank, you may notice that most pumps only offer Diesel #2. This is because it is the most efficient. Because Diesel #2 burns slower, you don’t have to fill up the tank nearly as often as you would with gasoline or Diesel #1. This is perfect for long-haul truck drivers or people who may need to go a while before they are able to fuel up again.

Diesel #2 is also a good option year-round for people who live in the south, as winter won’t slow it down. This thicker diesel fuel can gel in freezing temperatures and cause it to sludge. If you are in an area that stays above 40 degrees year-round, you’re in good shape to use this 365 days a year!

It’s a Winner Either Way

At Hart Fueling, we are big fans of diesel fuel for on-road and off-road fueling. Whether #1 or #2, diesel fuel is much more efficient – which saves our clients money.  It is also better for the environment and allows engines to run more smoothly. Whether you need it for your vehicle, your equipment, or your generator – diesel is an excellent choice. Just be sure to confirm that your engine is indeed diesel – as a gasoline mix-up could end up costing you thousands.
