I was at the pump at Pilot today and the pump had what they called exhaust fuel at a higher price and I guess regular diesel. What is the difference? Is one cleaner burning than the other?
Thanks in advance, John M.
By "exhaust fuel" I think you are referring to DEF - Diesel Exhaust Fluid. It's basically a urea compound solution used in emissions control for newer diesels and it is NOT diesel fuel - it goes in a DEF exhaust treatment tank (you do not want to put that in your fuel tank!)
Diesel exhaust fluid - Wikipedia (https://en.wikipedia.org/wiki/Diesel_exhaust_fluid)
It was $2.79/gal vs $2.39/gal and it was in the pump. Could it be a fuel that is already treated? It was labeled exhaust fuel.

What Michelle said.
It said on the pump that the Blue Def was inside.?
Never heard of "Diesel exhaust fuel" but the smaller exhaust fluid pump nozzle is usually next to the diesel pump nozzle at the truck stops.
I for a minute thought I had pumped DEF in my tank and was worried. I called the Pilot and explained what I did and the pump I was at, she clarified it for me. I picked up the large nozzle and lifted the handle and then hit the button that said exhaust fuel which is exhaust fluid. She stated that if I used the large pump nozzle that I only pumped diesel and not DEF. DEF is on a different and smaller hose and nozzle. I thought it was coming through the same large nozzle I used, but it doesn't. I had a big scare for a minute and thought I would have to get the system drained. Lesson learned, focus on what I am doing. Now to change my underwear. lol
What happens if you put DEF in your fuel tank.

Also, blue is the color code for DEF. Blue nozzles on the pump and blue DEF fill caps on vehicle tanks.
My Son put some DEF in the fuel tank of a new truck. He thought the fuel filter would catch it and he carried a number of filters and replaced every couple of miles. Didn't work out. Cost him I think around 10 coach bucks to get truck repaired. Ended up selling in shortly later.
I hope this is not considered hijacking of this thread - but the thread title IS "Diesel Types".
As a relatively new diesel pusher owner, who never had any prior experience with diesel-fueled vehicles, I find all the various "grades" of diesel confusing. I DO know the difference between DEF and diesel, so that is not a concern, and I also know about agricultural (red) non-taxed diesel. When we stop for fuel (predominately at either Love's or Pilot/Flying J or Pacific Pride Cardlock locations) I just use whatever comes out of the diesel hose and hope for the best. I figure if all the trucks around me are using it, it will probably work in my coach. I see various stickers on the pumps about Diesel #1, diesel #2, biodiesel, ULSD diesel, etc. I am not clear on the exact difference between all these grades.
Should I be more proactive in selecting fuel pumps? Are there any types of diesel (found at normal truck stops) that I should absolutely NOT put in our tank? Is the percentage mix of biodiesel a concern? Inquiring minds want to know!
No. 1 has a lower gelling temperature. I haven't seen it in years, but I am in southern Ca. Back in the 50's it was needed in the Detroit's
Asking my question has prompted me to do a quick Google search. I have already found (on the official Cummins site) a clear statement that 20% Biodiesel is NOT approved in older Cummins engines (prior to 2002). I have already encountered 20% Bio fuel at Flying J travel stops in TX, so I guess I better start looking more closely at the pump. This is a bummer - one more thing to complicate the refueling process. :thumbsdown:

It may not be "approved" by Cummins, but I've used it for several years without any problem. It's generally pretty much all that's available and so I use it.
The last tank of fuel I got in Lynden Washington was B20 because that was all that was available. I have noticed over the last couple years how B5 has become harder to find and am worried about what repairs may be required after using B20 for awhile.
Does anyone know what changes I should make to mitigate the possible damage caused by using B20 in a mid nineties M11.
I know some of the Gurus will disagree but pick an fuel additive and use it,you can get diesel kleen for $47 that will treat 1000
gallons.
OK, let's go through the list of what you MAY find at a fueling station:
#2 diesel (used throughout the country in the summer, and in the south in the winter)
#1 diesel (used in cold areas as its cloud point is lower)
Bio diesel-- in varying percents. Some percents mandated by state laws (read that farm lobbies)
Off-road diesel-- dyed red. No road tax collected-- DO NOT USE FOR ON-HIGHWAY VEHICLES.
DEF= Diesel Exhaust Fluid. NEVER, NEVER put it in your fuel tank! Only used in those newer vehicles (like 2010 and newer) with catalytic converters. So, if you have a coach older than 2010 just pass this one by. If newer, make sure to ONLY put in the the DEF tank. Most RV manufacturers/chassis makers located the fill for the DEF in very different area than the diesel fill to lessen the chance of making a mistake.
So the yellow handle diesel is which one?
Based upon my experiences over the last 3+ years no changes are required. I changed my fuel filters recently, but I'm not at all certain that was necessary.
Usually Green. Pay attention to what you are about to do and most of the time you should be fine. The Key is to Pay Attention! :thumbsup:
Might as well get all the info we can while we are here,other then the dye what exactly is the difference in the off road diesel?
Usually nothing, untaxed gets the dye. I have seen high Sulpher off road diesel though at some off road pumps. But, They state on the pump NOT for 2007 and newer diesels. Most of the checks are on commercial trucks at weigh stations. The only time in my 12 years of trucking I have seen/ had tanks checked was in texas. i have never seen a rv or a diesel pickup in the check stations.
With that said it isn't worth the savings ,Because IF you do get caught with it in a highway vehicle the fines far outweigh the cost savings you felt at the pump!
Was asking because thats what they use on the offshore platforms,have used it on diesel engines 30 years old,but the diesels
only run when the nat gas ones are down,used it so long I thought diesel was red.
Wyatt,
Found this tech bulletin on Cummins QuickServe Online. May shed some light. I hope the link works for those not enrolled in QuickServe...

I didn't think any of us still bought at Flying J. As others have pointed out, it has gone from cheapest to one of the more expensive stations. No longer a fan.
The advantage to Flying J/Pilot is having their credit card/fuel card (through Good Sam). Can swipe the card at the truck lane fuel pumps, don't have to go to the fuel desk, and 6 cents off pump price.
Texas does do a lot of checks. They set up at Texas Motor Speedway fairly often and check RV's and PU's. I have heard that they check at Canton First Monday Trade Days, and many more of this type of events. We use the red diesel on the farm but I am afraid to run it in anything on the highway. My son said they were set up at the auction barn back in the spring. I am going to add another tank to run the generator off of, in the future.

But, I will take a Pacific Pride Cardlock automated fueling station over
any truck stop. They are almost always cleaner, less congested, and easier in and out. Fuel price is usually competitive with other stations in the immediate area.
Pacific Pride Commercial Fueling - Cardlock Fuel Network - USA and Canada (http://pacificpride.com)
I have the Pride Advantage card issued by Pioneer Fuel in Olympia, WA. it is a "swipe & pump" card honored at all PP locations nation-wide, and also at all Love's Travel Stops. Highly recommended.
application (http://www.pacificpride.us/application.html)
Chuck, don't you have to be commercial to join?
Negative. Just print out the application, mail it in. A very nice lady will call you and set up your account. Once you have the cards, you're good to go. They bill you at the end of the month - send you a email copy plus a paper copy in the mail. You have to link a bank account to your fuel card. About a week
after they send you the bill, they debit the owed amount from your bank account. No fees, no extra charges, no hassle.
I keep a separate bank account specifically for my Pacific Pride card and my Flying J RVPlus card. They both tell me (ahead of time) what I owe - I transfer that amount into the special account - they debit their payment out of the account. Do it all online - EASY!
EDIT: I just looked at the application form linked above. I see they now also allow you to pay by debit from a credit card account.
Here is the quote from the Cummins web site:
What materials are incompatible with biodiesel?
Natural rubber, butyl rubber and some types of nitrile rubber (depending on chemical composition, construction and application) may be particularly susceptible to degradation. Also, copper, bronze, brass, tin, lead and zinc can cause deposit formations. The use of these materials and coatings must be avoided for fuel tanks and fuel lines. Fuel fittings and connectors are acceptable due to the small surface area in contact with the fuel.
In addition bio-diesel has much less BTU content per given quantity. Which results in less power & lower fuel economy.
So it would seem that one can run B-20 in a pinch to get some where, But I wouldn't run it all the time.
I have a "Good Sam" Pilot/FlyingJ RVPLUS credit card, however, since Pilot and FlyingJ became one, the 8 cent per gallon discount with the RVPLUS card means their diesel is still 20 cents per gallon more expensive then paying cash to the competition. I have not used it for a couple years.
The DEF fluid is also known as AD Blue. It is used in a separate tank on some of the newer trucks and busses as well as on VW Touaregs, Mercedes and some Jeep Grand Cherrokee diesels. It is sprayed into the exhaust to modify the exhaust output. The AD Blue tank has its own pump, sender, and heater, and is generally a pain in the sit upon!! Also corrosive.
How do I know?? I have a VW Touareg, 2010, and the heater failed causing the stuff to solidify, block the sender and then cost $3800 to fix!!! VW picked up the complete bill I am glad to say. But if you look on line you will see horror stories re this stuff.
Fortunately our coaches don't need it (YET)!!!

Believe cummins diesel engines started requiring def after 2010 to meet epa requirements.
