Almost killed my truck today (DEF)

So, my first diesel, and this is all new to me.

I filled up at a Buc-ee's a few months ago and noticed that DEF was available to pump just like fuel. Blue pump handle, very cool.

A few days ago the DIC instructed me to add DEF. So today I pulled into Buc-ee's and topped off the diesel, then I grabbed the blue handle to add DEF. It was a bit of a struggle to get the nozzle into the DEF hole (difficult, actually) and when I tried to squeeze the pump handle fluid shot out and made a bit of a mess.

Several moments of confusion later, I realized that I had been trying to pump Buc-ee's ethanol-free gasoline into my DEF tank.

So:

1: Why in the fudge would Buc-ee's use blue to color-code their ethanol-free gasoline and DEF? Why not pink, or something?

2: Maybe an ounce or less of gasoline went into the DEF tank. Should I be concerned?

Thanks, guys.

IMO it doesn’t matter the colour, it should not be a identifier of the product. The actual label is the proper identifier.

Yes you are going to get a code or warning about the DEF. It may not happen right away but it will eventually when the dosing rate goes to max. It being gas, I would be concerned.

Whelp, she's in the shop. Started her up for the first time since this incident and, as you predicted, the DIC was complaining bitterly about the emissions system, and threatening to cap me at 65 mph in 175 miles.

Waiting to hear how much the Stupidiot Tax will be.

I get DEF there often because it’s cheap and easy. I’ll have to really watch this. Hopefully very little fuel got in there. On a side note I bought my first box of DEF in years last week. Forgot how expensive that is.

Its $12 here per 2.5 gallon box? What is it out by you?

Peak maybe. All they had. It was a truck stop. I pulled in there just for def and they had none at the pumps. Only station for miles on my route. On I25 east of Cimarron, NM. Supply and demand I guess. Usually around home a box is 15 bucks give or take.

Just brought her home from the dealership.
Needed a new DEF tank. Something about the gasoline killing the heaters.
I caught a break because they found one at another dealership three hours away.
And they flushed the lines.

Stupidiot Tax: $2266.41

Won't be getting the new front bumper and winch for a while.

Hmmmm Obviously You owners have the fear DEF god in every Keystroke, I been running 2.5 Gallons Distilled water to 1 Gallon DEF in My 2015 LML since New, Not a single issue, My 2013 Ram been on Distilled water (100%) during the summer months and 2.5 Gallons DEF to 1 Gallon Distilled Water Same for the D-max in winter. New Trucks (2018+) have quality Sensor that triggers Codes at 22% so its a diet of 2.5 Gallons DEF to 1 Gallon Distilled water, the 67/33% is just not necessary and that ratio hard on the DEF pump and has crystallized many DEF Injectors leaving the truck in de-rated power or worst. Here's a video on My 2013 Ram, I should do one for the D-max. Maybe next year......;) Yes I'm Todd From TC Diesel, in addition to My automotive and DSL companies I own and operate additional Businesses one just happens to be exterior remodeling.

Its the Same Caper11, I have one Owner/Customer at over 500K+ miles on his LML (2013), He's commercial transporter on 2nd set of Injectors and 3rd CP4 Pump, He just replace the CP4 at 510K. OEM pump at 256K miles . Same DEF/DPF systems Factory. He Does have Auxiliary filtration on OEM Tank and one 50 Gallon Transfer Tank Filtration. I Have tore down both of his CP4s, they were tired but likely could have made 300K miles. My guess he's nearing 600K+ miles. He wants to make 750K miles and replace engine and takes some time off.

Interesting, Are you operating in warm climates??? Adding water will increase the freezing point.
Unfortunately these are older trucks and I was wondering about the L5P.

Im on board with it. They go to lengths to establish different colored caps and fuel jugs - but dont have a standard for what dispenses in to those said containers. Ive personally fallen victim to the BP green being gas instead of fuel - thankfully i clicked the Diesel button so the gas handle just beeped and didnt flow.

Or notch the nozzle a certain way to limit what it fits in. Even though different sizes, still can fit a smaller nozzle in to a larger filler neck. The notch can limit what actually fits where

I didn’t think a fuel nozzle would fit in the DEF neck properly anyway.
Manufacturers are to blame, IMO gas GM trucks have a yellow cap, majority of the industry identifies diesel, as yellow, even diesel jugs. Color is unreliable method of identification, all black would be better.

A little off topic, but believe it or not, Jaguar/Land rover has a patented filler neck design that will only accept passenger diesel nozzles. Passenger diesel nozzles are not the same size as petrol nozzles…
Will not accept a RUL nozzle or a big diesel nozzle. Has saved many newbie’s….There isn’t any reason one couldn’t be designed for DEF the same way. 2.5’s could be designed with the same limiting dia spout as dispenser nozzle fillers.

I condemn API/EPA for handling the DEF % and all the BS Regulation EPA / API mandates on DEF, Thier hands are dripping of Green.

You can make your own DEF the DS (Distilled water is available everywhere) You just need a Source for the Urea, Some have claimed to used Stabilized Nitrogen in place of Urea error free.

Urea/water ratio in def was picked so that stays in solution thru the freeze/thaw cycle.

As long as the truck can increase the fluid dose enough to compensate for the water and still reduce the NOx enough to satisfy the NOx sensors life should be good.

Nationally, US pricing for bulk def is less than the price for diesel.
 
#36 ·
They just guessed. I have kept good track of the consumption over the years, You could overlay the charts.

Red, the Ratio is what causes most of the DEF system Problems. API certification cost about $7/10K yearly blood money, API also gets a royalty fee $0.001 that equals $1.00 for every 1000 gallons
sold. The USA spent 23+$ Billion on DEF 2020 that's 7.5 Billon Gallons that's what another $750,000.00 Someone do the math and correct Me please.

I here Ya, Here's the standard, You can meet these standards in many engines/vehicles without the 33% Urea API set. Why do I know , because I was running 90/10% and hitting these levels in My 3.0VM and that engine is dirty, no where near as clean as D-Max / Ram Cummins 2013+ Intake/ exhaust / EGR / Combustion events, Etc. Some In head EGR systems are amazingly good at lowering NOx, yet we still have that AECD (EGR) bolted to most on road Vehicle Engines..
