When to Choose Diesel #1 vs. Diesel #2
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.
Is Diesel #2 the Same as Regular Diesel?

Regular 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!
