A diesel exhaust fluid (DEF) cap is a part of a diesel vehicle that allows the owner to top off the tank and refill it with emission fluids to reduce the level of nitrous oxide emissions. These fluids are a real product that breaks down nitrous oxides into harmless nitrogen and water molecules. Most diesel vehicles use this technology, which is also known as after-treatment technology. It is stored in a separate tank marked by a blue fill cap.
The DEF tank is often located near the diesel tank. It is crucial to keep the right amount of DEF in the tank, because improperly used DEF can harm the engine and result in a costly service ticket. If you’re unsure of how much DEF your truck needs, consult your owner’s manual for details.
In addition to the fuel filler cap, there is also an AdBlue tank. This blue cap is located near the diesel fuel filler. It may also be under the hood or in the trunk. Unlike diesel fuel, the AdBlue tank contains a separate fluid called AdBlue.

What is the Blue Cap Next to My Diesel Cap?
The blue cap is an AdBlue filler for your diesel-powered car. This type of filler helps reduce nitrous oxide emissions from your car’s exhaust. The filler cap will usually be located near the gas cap and under your bonnet. Most new vehicles require this type of filler cap. Some models also have “SCR” or “Blue” in their name.
The AdBlue filler cap is found beside your diesel fuel filler cap. The cap is blue and labelled “AdBlue.” You can find information about the capacity of this tank in your vehicle’s owner’s manual. You will need to top up the AdBlue fluid when your car needs to meet emission standards.
Most new cars that use a diesel engine are now required to have AdBlue filler tanks. This is the legal requirement to meet the Euro 6 emissions regulations. It can only be used in cars that have 1.6 litres of capacity or larger.
What Does a Blue Fuel Cap Mean?
The blue fuel cap on a diesel truck indicates that the vehicle is using AdBlue fluid, an additive that helps reduce emissions from diesel engines. AdBlue is added to the tank of modern diesel vehicles and is necessary to meet Euro 6 emissions regulations. The AdBlue cap is located next to the main fuel cap.
Diesel exhaust fluid (DEF) is a nonhazardous mixture of 32.5 percent urea and 67.5 percent deionized water that is sprayed into the exhaust stream of diesel vehicles. This fluid helps reduce the harmful nitrogen oxides in the exhaust stream of a diesel engine. Some newer vehicles use the Selective Catalytic Reduction system that uses DEF to reduce NOx emissions. This type of system is installed in many diesel trucks and SUVs. The blue fuel cap is used to keep the DEF topped up and is responsible for helping the vehicle run smoother.
While some older diesel trucks don’t require the fluid, many newer models do. Diesel trucks with AdBlue fluid will need to be serviced regularly. This type of fluid is a mixture of deionized water and high-purity urea. AdBlue reduces nitrogen oxide levels in the exhaust by using a process called selective catalytic reduction.
What Happens If I Run Out of AdBlue?
If you are wondering What Happens If I Run Out of Ad Blue on a Diesel Truck, you’re not alone. Tens of thousands of drivers run out of AdBlue every year. In order to prevent any unnecessary problems, you should try to refill your tank as soon as possible. You can also stop your truck at a safe rest area and visit the nearest AdBlue distribution point. Until you can refill your tank, the performance of your engine may be affected. However, if your vehicle is equipped with an SCR system, your engine will reduce emissions automatically when AdBlue runs out.
A standard mid-sized diesel vehicle can go up to 620 miles on a single litre of AdBlue. However, the number of litres you need to refill your tank will vary depending on the amount of miles you drive, the type of driving you do, and the weight of the vehicle. If you’re wondering how often you need to top up your AdBlue tank, check your vehicle’s handbook or call a registered AdBlue dealer.
What is the Blue Stuff For Diesel?
Diesel exhaust fluid, or AdBlue, is a colourless fluid used in the exhaust of diesel cars to reduce harmful emissions. The substance is a blend of urea and de-ionised water and is a non-toxic, environmentally friendly substance. Its purpose is to combat emissions from diesel vehicles by converting toxic nitrogen oxides into harmless nitrogen and carbon dioxide.
AdBlue is a specially formulated mixture designed to break down exhaust gases to form harmless nitrogen and oxygen. It is a combination of automotive-grade urea and deionized water. The fluid is stored in a separate tank, and it is fed into a part of the exhaust system. The chemical reaction with the NOx emissions converts them into nitrogen, which is harmless to humans. The substance is not blue in colour, and is a mix of water and high-purity urea.
Unlike petrol vehicles, diesel vehicles use AdBlue fluid to reduce the amount of harmful nitrogen oxide emissions. The substance is injected into the exhaust system automatically, and helps to improve fuel efficiency. Modern diesel vehicles that meet the Euro 6 emissions standards use AdBlue to help clean exhaust gases. AdBlue also helps to reduce solid particulates in exhaust emissions.
Can Trucks Run Without AdBlue?
The question of Can Diesel Trucks Run Without AdBlue? has been on the minds of diesel truck owners for years. AdBlue is a chemical that helps clean diesel truck emissions. It is composed of urea and deionised water. Most of it is imported from China, but the supply has dried up due to trade problems and the cost of the product.
AdBlue is a product that’s injected into the exhaust system of diesel engines to clean nitrogen oxides. It is an important anti-emissions product that helps trucks meet Euro 6 emissions standards. This anti-pollution fluid is commonly found in trucks, but is also used in some newer models of diesel cars. Some manufacturers, such as Mercedes-Benz, refer to their system as “BluTec”.
The federal government has created a high-level taskforce to source supplies of the essential exhaust fluid. It’s a concern, because a shortage of the substance could cause critical deliveries to be impacted within six weeks, putting the trucking industry at risk. Fortunately, the government has plans to procure new supplies from Indonesia and the Middle East. Without AdBlue, modern trucks can’t legally drive. The trucking industry would be left without a way to transport goods from one point to another, which is vital for the Australian economy.
Can I Refill AdBlue Myself?
AdBlue is a chemical used in diesel trucks to clean exhaust. It works by reacting with nitrogen oxides to turn them into harmless nitrogen and water. The process has been used for years in heavy lorries and buses. But, if your truck’s AdBlue tank runs low, you’ll notice a significant reduction in performance and power. It may even become unable to start.
The AdBlue consumption of your vehicle is dependent on the exhaust gas aftertreatment system installed in it and the type of driving you do. A vehicle that is driven hard will use up more AdBlue than a vehicle that’s driven carefully in mixed traffic. However, a vehicle driven like an old lady will still use up AdBlue.
There are several ways to refill AdBlue in your diesel truck. Some vehicles have an extra filler cap next to the main fuel cap; others have a dedicated tank under the hood.
Why Do Diesels Have Two Gas Caps?
If you’re wondering why diesels have two gas caps, you’re not alone. Most cars have a plate under the gas cap that prevents leaded gasoline from fitting into the diesel nozzle. But this plate doesn’t exist on most trucks and motorcycles. Here’s a look at why.
Adding gasoline to a diesel engine will reduce its octane rating. Fuel with a lower octane rating will ignite too quickly in the engine chamber, causing a knocking sound and damaging the piston. Adding octane will delay the combustion process and protect your engine.
While gasoline and diesel engines share the same basic architecture, diesels are much heavier and contain larger molecules than gasoline. Additionally, diesel fuel is more flammable than gasoline, and its autoignition temperature is higher than gasoline. Because diesel fuel is heavier than gasoline, it can damage engine components.
