Does diesel fuel gell up in cold weather no matter if I use number 1 or 2. What additives should I use id it does. Also some gas stations don't indicate what diesel fuel type it is so are these all number 2 diesel. Thank you

There are many anti gelling diesel fuel additives available, just about any parts house or station selling diesel fuel has this product, which should be a winterized blend for your area anyway.

Yea, you should be fine. Unless you buy tanker loads of fuel in florida and carry it to minnesota or something. Or maybe if you have a huge farm tank and its summer fuel. I wouldn't worry about it otherwise.

Why do you ask?

Most Diesel fuel you buy is #2.
This is considered a "year round" fuel, but it will wax or gel below 0 degrees F.
For colder weather fuel companies sell a #2 blend which is thinned down to prevent waxing and gelling.

Typically you will only find #1 Diesel fuel pump marked as #1...#2 pump just advertise Diesel fuel
