Wow this is interesting thanks for the detailed information. This is good info!
I had 2014-2019 dodge ram 3500 models. I do cars hauling. Now I have 2022. It's a pile of garbage. Transmission, differential, manifold,... everything! Especially def and emissions systems. Meanwhile I have to pay my insurance and leasing. 🤬😤
Ha😂
What about def in tank while truck lives in Texas which is HOT??
Here's a question. How much carbon is produced by having to:
Create distilled water
Create urea
Create all the parts and systems in the trucks for DEF
Create the packaging for DEF
Shipping the DEF
Disposing of the expired DEF
Repairs to vehicles that use "bad def"
Disposing of the plastic jugs and boxes
It's a JOKE
I'm so glad that the government has protected us from all this pollution. Hundreds of millions of cardboard boxes, plastic jugs, toxic chemicals, additional mining for rare metals and additional hardware under your truck, poor fuel economy, and expensive repairs if your toxic chemical has expired. Wheww. this is so much better. Thank you government.
Couldnt have said it better!! I would love for a person to strongly present this evidence to the environmental cheeseballs that speak to Congress. No idea about 2nd and 3rd order consequences to these mandates/exhaust systems
We've come a long way with internal combustion engine emissions, but I think we're at the end of the road. Today we're only robbing Peter to pay Paul. We can reduce tailpipe emissions and have a clean running engine but at the expense of mining and its environmental impact, millions (if not billions) of pounds of single use plastics (and the environmental impact to produce them), as well as burning more fuel; which causes increased dependence on foreign oil, and the environmental impacts of drilling for and refining crude. Emissions reduction was never about saving the environment, it's only a political game.
I wish tim would of brought this up in the interview
Want less emissions use the technology you already have to go farther down the road per gallon. The only thing def does is give diesel truck owners a bigger maintenance bill and breakdowns on the road.
Saving the planet one cardboard box and plastic jug at a time
LOL
Not to mention API has a pretty good cash cow. I wonder how much they charge annually for certification?
And 30% more fuel used in order to produce less pollution. lol
You can safe money and avoid the plastic crap if you fill up your DEF at the Semi Gas Stations. It is probably fresher also!
@@marckruse2181 I specifically avoid the truck stops. Have had friends tell me horror stories
DEF interacts with the the Selective Catalyst Reduction chamber which is down stream in the exhaust system, DEF does not go into the engine. If not for a stupid sensor in the SCR it would not know what or even if you had DEF. One thing that needs to be done is a drain plug should be on all DEF tanks so the owner can drain the DEF if it reaches a certain age so they can add fresh DEF. Most problems with the DEF system are because the DEF just became stale and that is the start of your problems in the DEF system.
As for the API I personally think they create more problems than they solve with their stupid standards. The entire synthetic oil fiasco could have been stopped if only the API had stepped up and said sorry Castrol but Group III Conventional oil is not synthetic just because you hydro cracked it which only removes some more of the impurities in the oil. The molecules are not changed or created like a true Group IV PAO synthetic or Group V Ester synthetic.
It was the Better Business Bureau's National Advertising Division (NAD) that made the decision that Group III Conventional oil could be labeled as full synthetic oil and sadly the API stupidly went along with that dumb decision making consumers the losers in that stupid decision.
Are all synthetic oils just cleaner conventional oils? Just bought a 2022 ram 3500. Its my first diesel truck.
@@ckryegrass11 No. A true 100% synthetic oil has a molecular structure where all the molecules are the same size, because it's synthetic--synthesized. Conventional or dinosaur oils have molecules of differing sizes.
Airplanes can test their tanks, why cant a truck ???
ALways funny to me -- is the BS that petroleum people put out to the general public to make money - the exhaust outlet on my 6.7 diesel engine smelled like Clorox in the first 30 thousand miles - I mean to the point of me wondering what the hell was the smell that I was smelling when I stopped to take a pee on the side of the road at midnight behind my truck - and after another half dozen times of stopping on the side of the road to do my thing -- did I realize -- that it was my exhaust with no doubt - after doing many dozens of hours of research on that situation - I find out -- that people had GRIPPED at the smell of diesel -- so they decided to TRICK the idiots that did not like that smell of diesel fumes stinking -- that that was the ANSWER -- make it smell like Clorox - - and the dumb s general public will believe that it is a cleaner thing - Yu cannot imagine my SURPRISE at what I found out -- and if yu don't want to believe it -- that's OK -- yu are another dumb s that will believe whatever BS they hand out -- ahahahahahahahahahaha - it was quite shocking to find out such things - and now -- it is a wonder drug for diesels making 100s of millions - and really does NOT stop pollution AT ALL ! ! ! -- un frickin real chit it is --- and as for the age thing of DEF -- it is what they planned all along -- money making racket it is - they know how to stabilize it for months -- and they do not - PERIOD ! - they know how to stabilize fuels for years in reserve - and do not do it for us to benefit from - we have to buy cheap chit for that purpose that does not really last for long -- BS they do - they are surely turning into communist pigs on money matters - a SHAME on america it is -- YEA - I know -- yu believe what THEY say -- ahahahahahahaha - GO-FISH !
@@ckryegrass11 -- ahahahahah-- they are not even really cleaner -- they are just not made of petroleum - and have a lot more additives usually - which account for the better supposed quality - they have more dispersants and detergents - it costs them about 35 cents extras which they get back about 12 dollars for -- ahahahaha - it is true whether it sounds believable or not - most of the better ones have been put out of business - and the different sized molecules don't mean chit - my poop has different sized molecules also - it is just a way to make them cool down better and add a little bit of lubricity if it has it - which most lubricity is not made of the better kind - I have a few quarts left of some that was being made by a company that was hired to make it for a certain application in some odd made trucks - and when it succeeded - it was disbanded for money making reasons - by big companies that stopped its production - for obvious reasons - I bought about 20 quarts of it - it has the ability to make wear componence last a WHOLE lot longer - 40,000 miles worth was it proven affects - and was still said to be able to last much longer if needed - with only filter changes once a year or 40,000 miles - oil companies are so full of rat chit -- ahahahahaha - just buy Rotello syn - and change it at or before intervals is all that is needed - change filters before winter and after no matter how many miles is what is proven -- yu should be able to get 20,000 miles or so -- all other info is BS and is used to make money from - FACT ! ! - everybody will believe whatever they like the sound of -- it is all BS - OIL is OIL - some have more additives - none have much for high mileage usage - they cant sell as much that way -- ahahahaha
So glad to see this video. Self life and drain when not using my rv.thanks
I just love saving the earth by throwing away a box and a plastic jug every month as well as burning Urea out my exhaust!
DEF doesnt reduce pollution at all by itself. What it does is regenerate the 3 way catalyst (SCR). Power plants use ammonia for the same purpose on their SCR's.
@@mizzouxc3824 actually it's not.
its correct we use ammonia and catalyst to have 0 emmision
DEF also requires you to spend more fuel. We’re basically required to collect as much pollution as possible so we can put it in our groundwater and back into the air.
This is great education for a new diesel truck owner.
I bought a diesel Jeep Grand Cherokee abouta yearand a half ago, not knowing anything about diesel believe me I just had an expensive learning lesson almost gave up on it (a couple people tried to talk me into getting rid of it) until I came across a couple of videos on def. Man if I would've seen some these prior I would've have save me thousands. Now I know it's more about maintenance. I'm on it now lol
Save the planet and money, delete the stupid system.
Awesome! My new truck (2000) miles only on it has been at dealership 3 weeks now-DEF pump failed, then replacement pump arrived-defective...
great video, helps understand DEF better.👍
What kind of truck is it?
All these specifications and API requirements and the one thing that should be required is a USE BY DATE... They should not be able to hide behind all these date codes that you need Indiana Jones to decipher.
Good point.
@@Pickuptrucktalk there is no drain on my DEF tank so if I deploy for six months or longer how to I refresh the fluid in my tank?
Very informative, thank you!
Wish my dealership was more clear about DEF when I purchased the truck... Thanks for the update
Most dealers don’t know this stuff neither. I certainly learned a few things!
My dealership had no idea of the DEF.. I heard later they had a whole fleet of pickups on the lot that had DEF issues... I think mine may have been one that had issues and never made a complete refresh or whatever it was they did..
The dealership sucks. The only thing they know how to do is take your money.
I've owned a lot of diesel pickup trucks over the years I just bought a new Ford in October I get messages I'm from Michigan and it's winter time now I have to do a manual regeneration I'm having a message pop up that it's cleaning the filter I still have my 2000 F350 4wd drw it starts ok maybe I should store the new truck beside the Corvette for the winter
buy DEF at diesel pumps rather than bottles at gas stations. Here in Calgary a 9.4 liter bottle is $30, I just filled up this week at a truck stop and the DEF from the pump was $1.10/Liter. So the same 9.4 liters is only $10.34 vs $30 in a bottle
What truck stop you going to in Calgary? I’m in Calgary too and just picked up a 3.0 diesel
I haven’t looked yet , but I am guessing there is a test kit to insure the DEF is still safe to use to protect the equipment.
I live in Arizona, it's over 85 degrees half the year. So you mean I have to start refrigerating my DEF? I guess I have to keep the Pabst Blue Ribbon in the garage...
LOL
Ok you talked about temperature and def the back trucks bringing it to store get really hot during summertime
Thanks guys great information to know
I use the DEF at the pump at gas stations, primarily at truck stops, like Quick Trip.
I was told by my drivers friend not to do that because it goes from one tank to another and can be contaminated. I just use supertech been good so far half what bludef cost
Carry a spare speedometer senssor in your semi truck and you will never be stuck at 5 mph. Just unplug the mounted speed sensor and plug in the spare and lay it on top of the transmission. The system will know a sensor is connected but not know how fast you are going. Most will default to about 45 mph.
Will that work on automatic like dt12?
Does that work on pickups?
Thanks for the info Tim, I’ll store my def in the basement in summer to prolong its life.
That's a good idea!
Good idea, Steve!
Why store DEF at all, just buy it when you need it, DEF lasts for quite a while before you have to add more to the DEF tank. That way you know you are getting fresh DEF and not using DEF that you have stored for months and no telling how old it is if you did not read the date code on it for how long it was sitting in a store.
@@jeffreyharmening4090 j
What about the DEF in the trucks tank, it gets hot every day, is that not a problem?
Many truck stops have def pumps. Fill up over there at Thornton’s. It’s much cheaper. No packaging. And it ain’t gonna get too old or too hot sitting in an underground tank.
I just purchased a diesel pickup and the dealership asked me if I have a truck stop near my home with a def pump. So I called the truck stop and asked them and they said yes they do. When I told the service manager that the truck stop did have a def pump he said good use it that is the best option.
Any issue using the DEF pump at Thornton ?
Update- I have now switched to Blu-DEF platinum.
@jko0526 why did you switch from the pump?
We use to have problems with it freezing in the tank on very cold days. Truck needed a reg but it was froze up. Truck had no power. Also for it do a automatic Reg u need highway with city driving. Only short haul the truck would never get its self clean out. No power.. That's why semis have Manuel reg button. Your can do a parked reg. U press it and engine would rev up. . Smoke would pour out Then after 15 minutes truck would idle down.
Thank you for your information. I am very grateful. What is the best DEF
Brand new equipment you know that a maintenance bill and down time is coming quick. Got a brand new bobcat T770 with that shit on it. And I have 100% confidence in this machine outside of the DEF system. Hoping there’s a machine guru out there working right now trying to figure out how to delete this shit so we can get back to productive reliable equipment.
I have a story and a question. I used to have a 92 Caprice. Once it failed to pass an exhaust inspection. I looked up on the net, ways to help this. I saw several tips on TH-cam and elsewhere, to slowly add Seafoam, to a vacuum hose. 6 ounces, while running. Then turn off for 15 minutes. Reattach vacuum hose. Turn on car, let idle, rev engine multiple tiles, until all dried particles, carbon, etc , are spit out of exhaust. Yes, that works instantly! I returned next day to inspection station, and car passed. Or u can add a whole can to gas tank, half a tank of gas or less, let it run until nearly empty. This has the same effect.
My question is related. I have a new company truck. Diesel. I get a.. engine will Derate in x minutes...every day. Since Derate and Regen has to do with same issue-exhaust particulate and the cat converter, couldn't I expect the same results, adding Seafoam,to my diesel? On a side note; because I'm one of those people who has to know how and why things work, I called Seafoam about 15 years ago to ask this question. I actually talked to the inventor and chief engineer of the product 😮😮 he told me it's 3 main molecular components, and how and how and why it works. Put shortly, it completely dries up , shrinks up, crusts up, all solid matter and clinging particulate, from ur injectors spark plugs piston heads cylinder walls, all the way out past ur cat converter. Like a chunky dried up riverbed in Africa in summer! Then is easily blown out, by normal exhaust usage. So wouldn't this also work on a diesel that uses Def? Thanks for anyone's answer.
Does DEF expire at the same rate while sitting in the DEF tank in a truck you don’t drive as often?
Why is he going on about things that might contaminate DEF harming the engine, when it's injected into the exhaust?
Because he is clueless
Scare tactics
plugged exhaust will harm the engine
@@trobstar7184 Takes a lot to plug exhaust. A little urea ain't gonna do it.
Lol
Awesome! Thank you! Could we perhaps have an interview on diesel fuel standards? Cetane numbers, lubricity, sulphur content, and last but not at all least biodiesels, both FAME and HVO and how they affect the quality of the fuel, with moisture and sediment. In Europe we have B10 ES 590 diesel, meaning 10% by volume FAME based biodiesel in otherwise mineral diesel. There are subtleties about storage and sedimentation, and there is a lot of bro science and mythology around this. Likewise with diesel fuel additives. It would be great to have his view on this. Great videos! Keep the diesel talk coming, love that stuff 🤓✊🏻
Hmm... I’ll see what I can do.
Please how are you going to possibly regulate the temperature of the DEF in the trucks holding tank itself.
Def is Def it it meets the ISO 7000 standard
Distilled water and Pig Piss!! How could that ever go BAD?? It was Bad to begin with! Lol 😆 🤣
Does high altitude and or freezing affect def running in the vehicle. DEF freezes at 12F what does do when you crank up the truck?
speaking of, can you do a show on windshield wiper fluids next?
So if u live in the desert do u store the def in a cooler. What about the def in the truck when it’s a 120 out side for 3 months. Do I need to worry?
I'd worry. Excessive heat or cold is a problem for DEF.
I saved damaging and harming my truck by deleting it. 👍🏻🇺🇸💨
How can I get mine deleted?
So def fluid has expiration date, can it be stored in garage when temperature are really cold ? Like -15 celsius or do i need to bring it in my house ?
Would this product work the same on a regular gasoline old truck? Thanks
Why would you want to add Def to a gasoline truck?
@@Pickuptrucktalk I was given a 2.5 Gallon jug, later I foud it was for a diezel vehicle.
@@1945temo DEF is for diesel engines only. Worthless for gas engines.
In my Colorado’s 2.8 Duramax I just use the cheap stuff from Walmart. I always look for the newest manufacture date. Been using it for 4 years. Never had an issue. I store a 2.5 gallon jug in my closet under a blanket so it’s a pretty stable environment. I just don’t think there is a whole lotta difference between GMs version and Walmart’s.
After four years you need to pull your DEF injector and I bet you will find that the hole is bolts to on the SCR is almost completely plugged up with only a small hole left in the white build up for the DEF to get through. The DEF injector is easy to pull and check.
@@ramecodiesel8271 who cares? I’ve ran the cheap stuff in my Ram for 226,000 miles and no issues. J/s
I use Wal-Mart DEF in my 2.8 and now in my 3.0. Have know problems. There is a youtube channel i watch Wal-Mart DEF same company that makes Blue DEF.
What is the price difference between the 2 brands?
@@mp5kfisher241 price varies upon where you buy the non Walmart stuff. The Walmart stuff should be priced the same across the country.
if DEF goes bad over 85 degrees then you wouldn't be able to use it in the south, we've had 100+ temperatures for more than 60 days. From what you've said I wouldn't be able to drive across town before the DEF would be bad
Storing it outside for extended periods is the issue.
Great info!!
Glad it was helpful!
@@Pickuptrucktalk yes it was SO helpful. I had been considering a diesel pickup, but this sounds like such a scam. Had to have been big overpaid cubicle bureaucrats that though up this wonderful fluid. Haven't heard the acronym keep it simple stupid. But hey at least I got to have my ears blasted out by your loud music. Thanks. Win win! lol
How do you control the temperature of the def in the vehicles def tank in very hot weather.
So how long will DEF last in a vehicle in Arizona summer before it chrysalises? In the tank not stored in the trunk.
So what happens if it’s in your tank system here in south Texas weather is 100 degrees and over
Pretty much every diesel truck I’ve owned in the last 6 years burns through a jug of DEF every 10 000 km. As long as your drive is he vehicle regularity this should be an issue as long as you put fresh fluid in your tank.
I've checked for dates for years and never saw one. You never explained about the date code....
I try to get it at truck stops so hopefully it'll be fresher..
There is an entire chain of custody protocol that keeps it below 66degrees until you buy it. I have read. This is the Mercedes plan.
Is there a difference in the bottled jugs? There are different markings on the boxes and a higher price. Do you think it's just " marketing " ?
Can someone clarify, exactly what 'major engine repairs' may be needed if the juice which squirts into your exhaust is the wrong flavour ?
Did you happen to ask what it is made out of ? Not sure what chemicals are in it. Thanks Tim keep the great vids coming
Automotive grade Urea and pure water basically.
Tim is absolutely right. 32.5% automotive grade urea in 67.5 percent pure (distilled, deionized) water.
So what’s the difference between DEF being stored in a container vs sitting in the tank in the truck? It gets to 105 where I live. Seems like DEF is a Diesel engine destroying liquid and this is why we delete our trucks.
Buy well and get a two year life. So in the heat, at least 1 year. Think you’ll get thru that?
How do I delete it? I have a chevy cruze diesel. The pump is bad
How does DEF destroy a diesel engine? Its injected in the exhaust.
So I have the DEF light on and it have flour but don’t know what’s the problem
Yes But, How wonderful that test are done, don't keep too much on hand, but how long is too long? How does heat affect it, etc. ?????
@12:50 API doesn't license but the API logo means the product has been CERTIFIED to meet API's standards!!!
The word license and certified have different meaning!
Will the truck tell you (in advance) when a regen is coming? Can you decline the regen at that time? (For instance, you’re pulling in to work and it starts a regen and you can’t just keep driving to let it happen normally)
I don’t know of any truck that allows that, usually they tell you when you are starting a regen and it’s best to let it regen when it wants.
Because regens have to occur it should be mandatory that all Diesels have a button you can push to do a manual regeneration for the exact reason you just described. There is no reason anyone should have to go to a dealer and pay them to do a manual regeneration.
Regen will continue the next time you drive it. That’s what mine has done on both Duramax trucks I own (6.6 and 2.8)
Can you comment on the difference of regular def and platinum def? Is it really worth the extra money?
I've found price matching makes up the cost difference. I'm going to continue with Platinum.
@@cashishift I’m still trying to find out what the platinum def does for the engine?
Im sticking to Platinum since Banks recommend it.
It is my opinion, but engine design should not allow damage from the transmission, or from DEF or from the
exhaust-system nor the steering or brake system.
How hot do the DEF tanks get in the car?
What happens to the 4 gallons inside your tank when it’s above 100 degrees outside everyday?
Exactly I was going to ask the same question
High heat is one year life. So use it up within the year of manufacture.
Does ag commissioner check gas,diesel,def pumps
I enjoyed the video, but I’d like to correct a couple things. 1 DEF never goes in your engine. You cannot screw up your engine. DEF or bad def or no def goes in the after treatment system. It can be very expensive to repair but it is not in the engine. Second, most commercial trucks do not buy bottled DEF we buy our DEF at truckstops with the bulk tanks. you want to go to a big truckstop that uses a lot so it rotates. Modern diesel engines that have been deleted run better have more power and get better fuel economy than emission engines. They are just illegal.
Who said DEF goes into your engine?
Tim I guess I misunderstood what you were saying. I thought you said bad def could damage your engine. I guess I heard wrong
@@Bigben-pz8bx Honestly, it has been so many years since I filmed this video, I don't recall what I said. That's why I asked. LOL
13:47 you say bad storage could damage your engine. But I think you mean the parts using the def only.
First time diesel owner. If I were to delete my 2022 3.0, I wouldn’t need DEF any longer?
Is Blue DEF Premium needed? Worth it?
So it collects your exhaust and then dumps it out of the exhaust onto ground ?. So what’s that do to the trees and ground life and water ?
Most people fail to understand that emissions controls have brought us more powerful and economical engines. In my house, our pickups are diesel. My wife's truck is a 2018 Ram 2500 Crewcab 4wd 6.7L. The engine is rated at 370hp and 800 lb/ft torque. 26mpg @ 55mph. And is rated to tow 17,200lbs. The mechanical 5.9L of the first Dodge D250 pickups. Got 14mpg @ 55mpg. Were rated at about 160hp 400lb/ft torque. And was rated to tow about 8,000lbs. And made a lot more noise! A gas D250 pickup got 9mpg.
Starting in 1974. The DOE, EPA, engine manufacturers, and the major oil companies did testing on water injection to the intake system for pollution reduction. A benefit was actually MORE power and BETTER fuel economy economy under most conditions. But the best improvement was with the electronically controlled common rail injection systems.
We got stuck with after treatment and DEF as a polluction reduction system. Because people just don't keep fluid levels correct.
With DEF, if the fluid runs out, or is not the specfied fluid. A warning light comes on. You got 50 miles to get to dealer for service. Or the computer will shutdown the engine!
The study had also tested various alternate fuels and formulations. Some formulations reduced emmisions. With similar or better fuel economy.
To me, DEF is messy! Requires keeping the injector cleaned. And works best with the tank kept at least half full. If you run the tank low. The injector must be cleaned more often. To clear the crystals that build up.
Good points! The 2019 and up Ram Cummins is even MORE powerful, better mileage AND uses less DEF!
My 05 Dodge Ram doesn't have any of this useless garbage. When and if I decide to get a new truck it's going to be fully deleted and tuned. The def is going in the toilet where it belongs and the rest of the emissions junk is going to the scrap yard.
@@duckwacker8720 We’ve got a badass over here!
Newer trucks are far more expensive, too!
You credit the emissions guidelines with automakers advancing their engineering to get better mileage and not the pursuit of higher profits? I disagree. Automakers are financially incentivized to make more efficient and stronger motors.
How long will the def last in the def tank on the truck in AZ in 115 degree weather?
I live in Las Vegas and was thinking the same thing. I haven't found the answer yet.
Many guys on current Forums are putting in a Gallon per 100 miles when towing. The new trucks when compared to 2019 and 2020 trucks are using way more DEF.
How do we ensure temperature control from the vendors? Should we sniff before filling up?
Thanks for the mental image of guys walking around gas stations sniffing DEF fluid.
Is something being developed to clean a DEF system? Similar to putting additive in fuel...
doubt it.. Then the diesel techs and dealerships would lose out on the $3,000-4,000 repair when your SCR or DPF gets buggered!
Isn't saying DEF Fluid like saying ATM Machine?
Our workplace has a big tote that they leave outside for us drivers to fill up with. Is it bad that it’s sitting out in the sun all day everyday? We have multiple dump trucks and work tool trucks that end up derating.
I would think that they would put two and two together that that tote is the issue. It just seems prior we used to stop by gas stations to get def and we never had derate issues back then. So I was curious if thrm leaving thr tote out in the sun could be an issue.
I would suspect leaving it in the sun is a problem, yes.
It could be simply a aging fleet.
@@kmg501 oldest truck is 2018 kw t880
Thank you for effort to do this , but your audio volume its really low.
What is certification we should look for
Storing it at higher temps? That makes no sense. Since my trucks DEF tank is, well, mounted in my truck and it’s 98°F outside, and my DEF capacity is 8,000 miles or so, that DEF fluid is in my truck for about 9 months. During that 9 months it’s stored in all temp ranges that the truck is in.
Def in direct sunlight will affect the uria reading which is if I remember around 32.5. Doesn't touch the engine just throws codes to make people spend money at the dealership. Def in your truck no matter how hot it gets won't change. Its a dumb system and causes too many issues heavy or light duty.
Maybe we should only fill the def tank halfway so it doesn't break down.
So don't store above 85. And if you live in Sacramento, Phoenix, Mojave??? So how fast is deterioration in 90 to 100 quite common in these areas, especially in DEF tanks that cannot be openly cleaned? 8:00
I was told by friend that add half cup of Ammonia NH3 to full tank DEF is good to clean the filters. Is that true?
What? I've never heard of that one. I wouldn't do it myself, the trucks are designed to clean out their own filters which is why regen exists. My guess is that's old school thinking and doesn't apply to new diesels.
I need help I think my def has crystallized in my freight liner cascadia. I was at half a tank with def and then put new def in there and it’s cold outside it give me code 5246/0
What about in cold weather like freezing-30° driving not storing Def?deiesel needs antigel what about def?
Going to be an issue IMO.
How much DEF is used in like the Ford F250 driving on the highways and the cities, like how often should it be addad?
No simple answer to this question.
We have a ford f350 diesel with 113,000 miles now that we purchased brand new back in 2017. It is my daily driver vehicle and frequently pull our rv as we are living full-time on the road since January 2018 and present. I always fill with def to the max and when it gets to half mark, then fill it up again to the top to circulate and mix old with new def. Once and I while, I run it close to empty, then fill it back up until full. O, and I do my best to use busy truck stops to fill for def and diesel fuel. For the past 5 years and now at 113,000 miles and with just basic maintenance(I do it myself on my own garage or in the middle of the desert when camping), no major issues and truck runs like very close to, when it was new.
It's 2% of fuel consumption
I have a 2021 GMC 2500HD duramax. Is it better to fill DEF at the pump?
It’s personal choice really.
You buy bulk DEF at truck stop. How do know if fresh and if it's quality Def.
Look for the date on the package.
Glad I don’t use def but I do pour all my filtered used oil in the fuel tank runs great 27 miles per gallon of fuel 4x4 3500 duelly
Does DEF still degrade when it is in the DEF tank at 100 degrees in southern states?
That is a very good question especially if you don't drive much and some of the DEF sits in the truck's tank for a longer period of time
Def,pull that money out of that pocket $$$$, we did have that stuff back in the 70s- 90s.
DEF dosent go into the engine or fuel its completely seperate from the engine so hmmmm maybe I'm overlooking somthing here. Many drivers I know have deleted their def systems and haven't had any issues. Cant get away with that in California though.
So what is the difference being stored in your truck in a bottle vs being in the def tank of the truck?
The interior of the truck will get much hotter than the DEF tank will that is in the open covered up by the body work of the truck. Think of it this way when you get in your vehicle after it has been sitting for a while it is far hotter than the outside air.
My 2017 ram has nothing but emission problems. I absolutely hate the def system. I know people who deleted the def system and the truck gets better mpg/longer oil life.
Yes a delete is preferred I was on the edge of it and waited too long.. now it seems all the pipes, tunes and tuner companies have died off..
Can you delete the DEF sensor? I heard that this can be done and runs a thousand times better.
You need a mechanic that can bypass sensors and computer chips that will disable your vehicle. Maybe early models but very hard to work around modern setups.
And it’s also a super dense heavy product to transport around in bulk. Burning even more fuel.
My buddy hit 100k in his Dodge…right out of warranty $3300 later.
What about the DEF in the vehicle already? As far as heat and expiration.
I imagine the under hood temperatures are pretty high. How long between DEF refills on lightly used diesels? How long can DEF sit in tank before going bad?
I'd let it run down to completely out and then fill it up. Depending on your climate, you should expect anywhere from 1-2 years before it goes bad in the tank.
@@Pickuptrucktalk then why/how does it go bad in the jug at 80+ degrees? But not in the tank at 110 in the summer?
@@urbanvampyre9371 they said it in the video...it doesn't instantly go bad at high temps, it just degrades faster. They basically insinuated that at high temps it would be okay for a year, but if it's stored in climate controlled environment should last 2-3 years.
I only fill my DEF tank to half full each time and then run it down. I always want a fresh supply in my tank. I don’t know if that’s a problem in the Wisconsin winter but so far so good.
Incorrect my ‘19 ram drank it 20% more than my ‘17
Commercial DEF already has to meet ISO 22241 standards - what does the additional API certification ADD??!!!
Supposing a person bought some DEF and it has a use-by date on it and it expires, how would someone dispose of that DEF? Surely, you can't pour it down the drain but how would you get rid of it?
Actually urea is a fertilizer. I would bet you could dilute and use on the lawn.
I think this 80° storage doesn't makes a lot of sense, how can it be in my truck in 115°F, what is the difference? I think is more like don't store it in hot temps for extended periods of time
The only mistake I could make with DEF is to buy it. 2000 F-450 4x4 dump-bed 7.3 Powerstroke 50k
So is the Walmart DEF as good as blue def sold in auto store? I’m asking sine I have a new baby 3.0 duramax yukon on the way……
DEF is DEF.
@@Pickuptrucktalk thanks appreciate the response
I literally learned nothing from this video other than DEF has a shelf life and a temp max, both of which don’t seem to apply in the tank, just in the jug. Someone please explain.
Exactly. That was a lot of time to say very little.
Can we have a segment on Cenex diesel. I here these commercials saying Cenex diesel is better for my rig but it’s definitely more expensive then regular diesel why?
I've reached out to a diesel advocacy group to ask some questions.
Higher Cetane? I’m sure it’s in the additives.
They charge more for everything. With their gas they start with 87,89 and 92 octane then add the 10% alcohol that boost the octane level two points.
Diesel power magazine(when they were still in business) had an article about that. It had higher Cetane, higher lubricate additives and so on and so forth. In other words it was ultra premium diesel.
Just bought my first Diesel over the weekend, 2022 Chevy 1500 with the 3.0L duramax. The DEF gage was showing around 3/4 full. Do you guys let the DEF deplete to almost empty before adding new? What is the best DEF to buy for these small Duramax engines?
Just buy the Wal Mart Supertech brand.
Buying more expensive DEF is just a waste of money.
There is a difference in def. Platinum actually shows proof.
Do NOT allow the DEF tank to go below half. DEF can crystalize and cause real headaches. In fact you want to inspect for any crystallization and see why it is happening. Clean with distilled water. DEF is a specific formula, so it is either manufactured correctly or it isn't.
@@kmg501 thank you buddy! I had some sensor go bad a few weeks ago, still under warranty and i think it had something to do with emissions, im wondering if it had something to do with the DEF, the service engine light had came on.
@@PNWLiving1725 whats the difference between the standard Blue DEF vs the Blue DEF platinum?
Is the difference between Peak Platinum Def and regular Blu Def a formula change or a process change have can the standard be the same with a different formula
Everything I read about Platinum says it is better so I have started using it. A friend of mine has 30k on his truck and has been using Platinum since he bought it. He pulled the DEF injector and he called me to come over and take a look at it. It was almost completely free of any residue. So I went directly from his house to the store and bought some and poured it in my truck.
One to three years, you say...
Was that so hard to say???
Thank you... That's what I needed to know... However, all the other information was equally important to know...
