Fuel quality? Isn't all diesel the same?

So I bought a new 12 F250 4wd 6.7. It's my first diesel. I have been trying to educate myself on the ins and outs. Holy Cow... Tons of stuff to learn. Which brings me to fuel. Cetane in fuel. Do I need to put additives with every tank or are most commercial fuels ok. How about truck stop diesel? You guys have any fuel issues?

just dont run "red gas" as its called....aka off road/non taxed. other than they your ok as your truck is made for the ulsd where as 6.0/7.3's aren't cetane in your case is more of a preventative...But if your in cold area I'd carry the 911 version of it (red bottle). I'm sure someone else with your motor will chime in...

What this nation needs is cleaner thoughts and dirtier fingernails...

You don't say what part of the country you are in but sound advice that works is to buy your fuel at a place that sells a lot of fuel. "Turning" the storage tank over often keeps the fuel fresh and most moisture picked up.

Buying fuel at a busy truck stop will keep the freshest fuel in your truck. That small Mom and Pop store on the corner won't sell enough diesel to keep it fresh.

Also, in cold parts of the country fuel is blended in winter to better handle the cold. The large truck stop chains are right on top of this because their business depends on return customers. Selling bad fuel to over the road truckers is certain death to these places so they have the good stuff you can bet. Try to find a busy truck stop that has a pump with the smaller nozzle and you are set.

If you ever had to use red off-road fuel you could. It would be an emergency as you can collect a very heavy fine if caught with it in the truck but it will burn just the same as clear fuel does. Red fuel is the same clear stuff with a dye added so the state can sell it without road tax. I buy about 2000 gal a month of red for my work machines. That saves about $.43 a gallon in tax for ag machinery. Just don't get caught on the road with it!!

I'm in Tampa Florida. Don't think I need to worry about winter blend. So the cetane rating for big rig diesel is ok? Good to know. I'm just anxious. I'm still on my full tank from the dealer. I don't want to do anything to mess this engine up. I hear these aren't our grandad's diesels. So I'm trying to be a little more selective. Thanks for the input.
