If you’re not familiar with DEF, it’s a substance that diesel engines require to run smoothly. While the amount varies depending on environmental conditions, it’s generally around two to three percent of fuel consumption. For example, a typical 36-gallon truck uses about one gallon of DEF for every full tank of gas. The percentage depends on a variety of factors, including the type of vehicle and geographic factors.
DEF is available at most service stations and is a mixture of deionized water and urea. It is mixed in a separate tank and injected into the exhaust stream of the engine. As the exhaust gases exit the vehicle, the urea in DEF reacts with nitrogen and water vapor in the catalytic converter. The result is a cleaner exhaust.
Using DEF is mandatory for new trucks, and it can be purchased at truck stops and gas stations. However, refilling DEF can be inconvenient and expensive. Jubitz offers DEF for sale at the pump, making it easier for customers to stay on the road.
How Long Does DEF Last in a Diesel?
Diesel exhaust fluid (DEF) is an important part of the emission safety process of diesel trucks. However, it is important to keep an eye on the DEF level to prevent it from getting contaminated. It is possible to ensure that your DEF is up to the standards by following some simple strategies.
DEF is a non-toxic liquid that can be purchased at any auto parts store or truck stop. It is usually filled into the truck’s tank via a fill port under the hood or in the trunk. You should note that the fuel and DEF tanks are different in size.
A diesel exhaust fluid (DEF) tank can last up to six months. The fluid should be stored in a cool place to keep it from freezing. DEF should also be tested periodically to ensure proper concentration. Use a refractometer to measure the concentration. If the concentration is below minimum specifications, it will freeze.
How Much Does DEF Fluid Cost?
Diesel trucks use DEF to reduce emissions. The fluid is a mix of water and urea. It’s also non-flammable and safe for vehicles. It’s used in Selective Catalytic Reduction systems, which change NOx emissions from diesel engines into water and nitrogen. This fluid costs about two to three percent of a truck’s diesel fuel consumption.
The shortage of DEF is already having an impact on U.S. truckers, according to Ashley Poole, the owner of a truck repair shop in Missouri. While older engines can function without DEF, newer Tier 4 models are required to use it. Fortunately, a shortage has been averted so far, but it could have an effect on trucking operations.
Typical light-duty trucks consume two to three gallons of DEF every 800 miles. Most new trucks will go 8,000 to 10,000 miles on a tank full of DEF. However, the actual rate of consumption will vary based on the fleet size, driver experience and driving conditions. Truckers can purchase DEF with their company fuel cards, credit cards or cash at most truck stops and retail gas stations.
Can I Use Water Instead of DEF?
In an emergency, you can use water to flush the diesel engine, but this can lead to a variety of problems. For instance, water can corrode components of the engine, which may lead to costly repairs. Dealers may even recommend replacing the entire DEF system.
In addition, water is not an approved substitute for DEF. A DEF-free engine will fail to start. This is due to the fact that water lacks the necessary ingredients to convert harmful gases to harmless molecules. Furthermore, water can harm the environment and your efforts to meet compliance standards. Regardless of how well you follow the law, water is a poor DEF replacement.
DEF is produced from automotive-grade urea, which meets strict emission standards. It is a mixture of 32.5 percent urea and 67.5 percent de-ionized water. While human urine contains very little urea, DEF is a liquid that is readily available from commercial filling stations and vehicle parts suppliers. It is even easy to refill the windshield wiper fluid with it.
What Can I Use Instead of DEF?
A light-duty truck consumes about two to three gallons of DEF every 800 miles. This makes it possible for a truck to run for 8,000 to 10,000 miles on a tank of DEF. Your vehicle’s gauge will let you know when you’re low on DEF. Ford trucks, for example, have an easy-to-read low DEF light.
If you don’t have DEF on hand, you can substitute windshield washer fluid or distilled water with your truck’s DEF. However, you should only use the brand that is specifically for your truck’s DEF system. Distilled water will not damage the engine as much as tap water. The best way to avoid running out of DEF is to monitor its level regularly. Most engines have a gauge that tells you when DEF is low.
DEF fluid can be stored for months or even years. When stored properly, DEF will keep the engine cool. It can even be used in the winter months. However, DEF fluid will freeze up in the DEF tank if exposed to extreme cold temperatures.
What Happens If You Run Your Truck Without DEF?
Diesel exhaust fluid, also known as DEF, is required by the EPA for all diesel engines. It is a nontoxic solution composed of 32.5% urea and 67.5% de-ionized water that reduces the emissions of harmful nitrogen oxides. Most newer vehicles come with a built-in display for DEF level, so drivers can monitor their tanks to prevent deficiency. Running out of DEF may also void the warranty of the engine and damage the catalytic converter.
Diesel exhaust fluid can be purchased at most service stations, and is usually a very affordable addition to a diesel truck. The fluid is a dilute solution of urea and deionized water that is injected into the exhaust stream of the engine. Once inside the exhaust pipe, DEF vaporizes and begins decomposing into ammonia and carbon dioxide. The nitrogen is then removed from the exhaust by means of a catalyst, which releases water vapor and carbon dioxide.
The first step is to make sure you fill up your DEF tank. If you do not fill it, you could end up with a very corroded engine. Your truck’s engine will suffer significant damage if the DEF tank is empty. Without DEF, the engine will have a difficult time getting the required fuel, which will stall the truck.
