I have a 2004 diesel 3500 truck. What diesel fuel should I use? What diesel fuel should I not use?
Thanks

Above all good.

And after you fill up a few times, you'll notice most diesel pumps have handles that are green. On west coast I have rarely had a choice of grade of diesel. Do not count on green being diesel all the time. Maybe 95% of time but have ran across couple handles that the diesel is not green or they have green on some gas product. I always double check to confirm diesel and not gas before fueling.

Red die fuel...Mechanic put a tank full in mine, fixing my fuel line and tank..Long story short but is not worth caught. Odds are very slim you will get checked but of you do, a big time fine. By the way I have never been checked driving a big truck since 1975 and small diesel pick up since 2004. If you ever get red die takes about 5 tanks to wash out according to my state info office. In my case they told me to carry receipt for atleast 5 tank fulls and what work was preformed on my fuel system and make sure mileage is listed on reciept. Good thing we travel with computer now days, they directed me to this page. My state told me to look at this page and let officer that I know the laws and show them receipt for the reason I got red die.

Don't know if this was a typo, but it's 100% backwards from what it should be.

Here there are several fuel stops that sell #1, your truck will burn it OK, We run #1 in our 2002, 5.9 ok a couple times, but mostly #2.
#1 has a higher BTU count per pound than #2 it is more of a oil than #2 ULSD. which we are now required to run on highway.

For legal reasons stay away from "off road" dyed diesel fuel. Basically it is sold without the regular road tax attached to "on road" diesel. Thus could be a bad day if you get stopped and they check your tank.

#1 is mainly for cold climates to keep it from gelling.

#2 is the standard. But some stations sell a standard and premium versions. Couldn't tell you what makes it "premium" but does not seem to give any perceptible gain in MPG.

Your truck is out of warranty so no issues with biodiesel and a voided warranty. We only buy diesel at stations with high fuel turnover. Sometimes that means not paying the cheapest price. And we try to avoid biodiesel if at all possible though in some states like Illinois, it is just about impossible and the pumps only give you a range of percentages. We traded in our still under warranty 2012 Ram dually for a 2015 Ram dually because we are full timers and had trouble finding non biodiesel fuel in many places.

Right on diesel 2

Here in texas there is only 1 kind of diesel fuel sold at truck stops. Diesel #2. Some regular gas stations have labels on the pump stating if/how much bio is their diesel. Use at your own risk. If they have anything else its labeled as kerosene(red dye)


Some stations are obviously better than others. In my diesel, I only use a reputable place to fill up. I learned my lesson filling up at a raceway one time. didnt make it a couple miles before my dash started yelling at me and the truck went into limp mode

Don't use the red dye stuff.
