DEF (Diesel Exhaust Fluid) was first used by Ford in 2008. DEF will be used in a diesel-consuming vehicle if your Ford truck, van, or other heavy-duty vehicle was built after this year.
When did DEF begin to be used in diesel trucks?
When it comes to diesel engines, the agency has tightened rules since 1970. Prior to 2008, no one had to be concerned about the emissions that their equipment or vehicles produced; nonetheless, the first step was taken when the EPA mandated the installation of diesel particle filters on all 3/4-ton and bigger trucks. The EPA introduced diesel exhaust fluid (DEF) 2010 with the purpose of further decreasing engine emissions, particularly NOx and particulate matter. NOx and particulate matter were connected to a variety of respiratory and cardiovascular ailments, resulting in thousands of additional hospitalizations and deaths, according to their research.
With DEF being mandated by the EPA, you will find most new diesel trucks, SUVs, cars, and machinery are manufactured with selective catalytic reduction (SCR) technology and a DEF tank that needs to be filled.
When DEF is sprayed into the exhaust stream after combustion, the magic happens, removing the worry of power or torque loss. Once the DEF and hot gases chemically interact, the once-harmful NOx and particulate matter are converted to nitrogen and water, which is then expelled from the exhaust.
While many owners of SCR vehicles have reported greater reliability and longer oil change intervals, it is crucial that the DEF tank does not run dry.
Many engine manufacturers have installed numerous warning lights when the DEF level drops below a certain level, and if the level drops too low, the engine’s performance will decline to keep the speed limited until the tank is full.
A common assumption is that owners need to fill their DEF with each time they fill their fuel tank, however this is false.
The typical rate of DEF usage is 2.5 gallons per 800 miles travelled, depending on how much you’re hauling. DEF has grown more widely available as it has become a requirement in a growing number of automobiles. DEF can be purchased at the pump or in jugs inside of gas stations. It is also strongly advised that you should not attempt to make your own DEF due to the necessity of having the right mixture to avoid damaging your vehicle’s SCR system.
Instead, purchase DEF in portable containers, at the pump, or in bulk quantities to be kept in a refillable bulk DEF tank at truck stops, retail sites, and fleet oil distributors, depending on your needs.
When did the use of diesel exhaust fluid become required?
If you’re new to owning a diesel vehicle or heavy equipment, you should be aware of a key addition. Diesel Exhaust Fluid is what it’s called (DEF). Aqueous urea solution 32 percent, or AUS 32, is another name for this ingredient. 32.5 percent urea and 67.5 percent de-ionized water are used to make it.

The Environmental Protection Agency (EPA) mandated that diesel engines cut their emissions of nitrogen oxides (NOx) in 2010. Diesel Exhaust Fluid, an additive, is used to achieve this reduction (DEF).
This fluid helps to reduce NOx emissions and pollution in the air. As a result, it aids heavy machinery and trucks in adhering to federal pollution standards. Heavy-duty diesel trucks and equipment have featured a diesel tank and a separate diesel exhaust fluid tank since 2010.
Is DEF required for Ford diesels?
Instead of other brands or alternative exhaust fluids, Ford recommends Motorcraft Diesel Exhaust Fluid. Ford does add, however, that API’s diesel exhaust fluid, which is certified and fulfills ISO 22241 criteria, will operate in their vehicles.
When did the F250 begin using DEF?
The answer was provided by DEF (Diesel Exhaust Fluid) was first used by Ford in 2008. DEF will be used in a diesel-consuming vehicle if your Ford truck, van, or other heavy-duty vehicle was built after this year.
When did the DPF begin?
As a result, the infamous diesel particulate filter (DPF) was added into the exhaust stream in 2007, and diesel exhaust fluid (DEF) was introduced in 2010 to minimize particles and NOx.
Is it possible to run a diesel engine without DEF?
Vehicle makers must implement procedures to ensure that vehicles cannot run without Diesel Exhaust Fluid, according to the US Environmental Protection Agency (DEF). The driver of a vehicle receives a succession of alerts on their dashboard displays before the DEF tank runs out (much the same way as if they were running low on diesel). In general, an amber warning bulb will illuminate when the DEF tank level drops below 10%, flashing at 5%, and solid amber warning light will illuminate when the DEF tank level dips below 2.5 percent.
The engine’s power is lowered, a solid red warning is displayed, and the vehicle’s speed is limited to 5 mph until the DEF tank is refilled if the truck is allowed to run out of DEF.
Is it possible to pee in your DEF tank?
Please do not urinate in your DEF tank; it will destroy the SCR system, which will cost thousands of dollars to fix. We specialize in offering the highest quality Diesel Exhaust Fluid at Transliquid Technologies.
Is diesel DEF on its way out?
SCR is also making its way into the field of marine diesel. In 2000, the International Maritime Organization (IMO) introduced standards restricting the quantity of NOx emissions, which have since been tightened. Because some marine diesel engines are the size of a house, their pollution potential is enormous, therefore SCR and DEF go a long way toward cleaning these vehicles up.
In an interview with Roadshow, Charles Culverhouse, CEO of Old World Industries, makers of BlueDEF and Peak automotive chemicals, said, “SCR is a technology that exists right now and is being used all over the world to boost fuel efficiency and reduce NOx emissions.” “DEF is effective, and it is made from readily available chemicals that are already produced in large quantities for the agricultural sector. Infrastructure has already been put in place.”
That’s a crucial point to keep in mind. Diesel will not be phased out of the world anytime soon. We rely on diesel-powered vehicles to transport our goods and ourselves around the world, whether they are trucks, trains, or boats. While standard diesel fuel may not be the best long-term solution for the environment, SCR technology and the introduction of more cost-effective biofuels imply that we can keep things relatively clean until we’re ready to completely forsake internal combustion.
When did pickup trucks start using DEF?
In a nutshell, what year vehicles are required to have DEF? Since 2010, most diesel-powered passenger cars and trucks have been required to use DEF. To help them comply with DEF requirements, most of these cars and trucks are equipped with Selective Catalytic Reduction (SCR).
Is it possible to remove DEF from Powerstroke?
The diesel particulate filter is an acronym for diesel particulate filter. Diesel particles are released into the exhaust system when diesel fuel is burnt. Diesel particulates are microscopic particles that contain a variety of compounds that are detrimental to the environment as well as human health when consumed. The DPF is a filter that collects diesel particulates before burning them in a regeneration cycle.
In the 6.7 Powerstroke exhaust system, the DPF is the third emissions component. The first is the diesel oxidation catalyst, or DOC, which is effectively a catalytic converter that bolts directly to the downpipe. The selective catalytic reduction, or SCR, system is the second. The SCR system converts nitrous oxide to nitrogen gas and water vapor using diesel exhaust fluid (DEF). The exhaust gases enter the DPF system after being burnt down as much as feasible in the first two systems.
The EGR system is another significant emissions system to mention. Before the gas enters the exhaust system, EGR (exhaust gas recirculation) happens. The EGR system recirculates exhaust gas back into the intake system after combustion to be re-burned and cut emissions even more.
What Does Deleting the DPF System Remove?
Because the DPF is only one of four actual emissions systems, DPF deletions are a little more involved. A normal DPF delete kit, on the other hand, will remove the DOC, SCR, and DPF systems. The SCR and DPF systems are combined in the same pipe in consumer pickups. The DPF is integrated into the DOC on chassis cab work vehicles, but the SCR system is separate.
As a result, uninstalling the 6.7 Powerstroke DPF will get rid of:
- Catalyst for diesel oxidation (DOC)
- Filter for diesel particulates (DPF)
- Cat Reduction on a Selective Basis (SCR)
- Exhaust fluid from diesel engines (DEF)
Because the DEF fluid is only required for the SCR system, it is no longer required once the SCR system is removed. You have the option of totally removing the DEF tank or simply plugging it in and leaving it in situ.
A DPF delete kit is nothing more than a single piece of exhaust piping. It connects to the downpipe and muffler, removing any emissions components in between.
Does a DPF Delete Remove 6.7 Powerstroke EGR?
The EGR system is not removed when the DPF is deleted. Separately, the EGR system must be removed.
EGR is unaffected by a DPF removal because it is simply a straight pipe or race pipe for the exhaust system. The EGR system, which consists of an EGR valve and an EGR cooler, is installed before the exhaust system. Exhaust gases go to the EGR cooler and then back into the intake system when the EGR valve is open.
On a 6.7 Powerstroke, removing the EGR system is little more difficult and time-consuming because it necessitates plugging the EGR valve and replacing some hoses. A DPF delete, on the other hand, only necessitates the removal of a part of the exhaust pipe and the installation of the DPF deletion pipe.
