What is the blue cap on a diesel truck?

But what exactly is AdBlue? Here's everything you need to know. Many diesel cars that meet Euro 6 emissions standards use a fluid called AdBlue which helps remove toxic substances from the car's exhaust gases.

What's the blue cap on diesel trucks?

This system is called Selective Catalytic Reduction (SCR) and can be found on 2010 and later model year trucks and many diesel pickups and SUVs. DEF is not a fuel additive and never comes into contact with diesel. It is stored in a separate tank, typically with a blue filler cap.

What is the blue fuel cap for?

A blue filler cap usually indicates where the AdBlue fluid should go, however always refer to your vehicle's manual first as older diesel vehicles may not require AdBlue. AdBlue is a colourless liquid that is made from a mixture of high-purity urea (32.5%) and deionised water (67.5%).

What happens if you run out of AdBlue?

What happens if your car runs out of AdBlue? If you run out of AdBlue while you're driving, then the engine's power and performance will be reduced to 'limp home' mode to limit its emissions and once the engine has stopped, it won't re-start until the AdBlue tank is refilled.

What is the blue stuff for diesel?

AdBlue is the trade name for a type of diesel exhaust fluid. It's a mixture of urea and deionised water that's stored in a separate tank from the car's fuel. When the car's engine is running, tiny amounts of AdBlue are squirted onto the exhaust gas produced, turning the NOx into nitrogen and water.

Can I refill AdBlue myself?

Can I top up with AdBlue^® myself? Yes, you can top up with AdBlue^® yourself. Every TotalEnergies service station sells standard 5L and 10L cans of AdBlue^®. TotalEnergies is also gradually deploying special pumps for light vehicles.

Do all diesels need AdBlue?

Only Diesel vehicles fitted with an SCR catalytic converter are affected. Originally, AdBlue® was used only by heavy vehicles, but nowadays more and more private vehicles are working with AdBlue®.

Can trucks drive without AdBlue?

AdBlue is a mandated DEF, which means trucking companies with modern trucks cannot legally drive without the additive. But it would be unfeasible for the trucking industry to stop operating.

Is AdBlue made from urine?

Is AdBlue® made from pigs' urine? AdBlue® is a synthetic, highly purified solution of urea and demineralized water NOT pigs urine. Whilst the chemical urea is in pigs' urine, it is found in much lower concentration alongside many other elements.

How do I know when AdBlue tank is full?

Simply tip the solution into the car and when you're full, you're full! Most vehicles with AdBlue will have a gauge of how full the tank is buried somewhere in the car's infotainment. Keep searching until you find it, and you'll know how much AdBlue you need.

Is AdBlue diesel exhaust fluid?

Diesel Exhaust Fluid (DEF) also known as AdBlue^®, is a non-toxic, colourless, odourless and non-flammable fluid. Stored in a dedicated tank in your car, it is injected into the exhaust system to clean exhaust gases.

Where does AdBlue go?

AdBlue filler location varies between manufacturer and model. Typical locations include the boot, next to the fuel filler, or under the bonnet. The size of the AdBlue tank fitted to vehicles varies between manufacturers and models, so therefore the interval between top-ups will vary.

How long will AdBlue last?

A full tank of AdBlue should last between 6,000 and 7,000 miles, on average. 1 litre of Adblue lasts around 600 miles, but this can be affected by your driving style. The more fuel your vehicle uses, the more AdBlue it will consume as well.

Can I use blue def instead of AdBlue?

Blue DEF can be used in place of any DEF OEM products. Blue DEF carries the same purity and composition guarantees as AdBlue. The product is ISO 22241, and American Petroleum Institute certified.

How often does a diesel truck need DEF?

DEF is consumed at a rate of about 2-3% relative to the amount of fuel you are using. This means between 1.2 and 2.0 gallons of DEF will be required for a vehicle with a 65-gallon gas tank. If you have a five-gallon DEF tank, DEF should be replaced every third or fourth time you fill up.

What happens if you accidentally put DEF in diesel tank?

What happens if DEF is put into the fuel tank? Typically, if DEF is introduced to the fuel tank, the truck will run poorly or even fail to start. Repairs to the fuel system can be costly. Components that have been contaminated with DEF will show crystallization after drying for a few hours as seen in Photo 1.

Why is there a shortage of AdBlue?

In short, Australia is set to face an AdBlue shortage by February 2022, if not earlier. And due to offshoring, we produce very little of AdBlue's key ingredient – urea – domestically. We've done little of late to support local production that otherwise would struggle to compete in the global market.

Can you disable AdBlue?

Disabling the AdBlue system is normally completed by reprogramming the engine management system, however some vehicles will require a small electronic unit to be hardwired into the vehicle.

Is AdBlue just urea?

While AdBlue is comprised of approximately 32 percent urea, our urine includes approximately two percent urea. It's mostly water, and the rest will depend upon one's diet. Some other elements of urine (again, depending on your diet) could be detrimential to the AdBlue system, and could cause some expensive repairs.

Why do trucks use AdBlue?

AdBlue® for Trucks, Vans and Cars

These include selective catalytic reduction systems in truck, car and van engines that use diesel exhaust fluids like AdBlue to prevent harmful exhaust gases being released into the atmosphere.

Will there be a DEF shortage?

While DEF markets will likely remain constrained for most of 2022, there are some things you can do to stay in control. Increase Storage Capacity. With logistics challenges causing issues, having more supply at your site can reduce supply chain strain and provide more time between replenishments.

Do all trucks use AdBlue?

Diesel vehicles make up 26.4% of all vehicles, up from 20.9% in 2016 and almost all modern diesel engines (those made in the past 10 years) use AdBlue. NatRoad's estimate is that more than 40% of Australian freight trucks use AdBlue but the percentage would be higher for long-haul tankers.

Does AdBlue stop DPF problems?

AdBlue favours regeneration cycles, so it participates directly in the maintenance of the diesel particulate filter. However, so that the diesel car's emission control system to work properly, it is necessary to make long trips (a minimum of 30 minutes) by regularly pushing the gears.

How much AdBlue do I put in?

How much AdBlue® does my car need? It is difficult to say exactly how much AbBlue® your car needs as models differ, but usage generally equates to around 1 litre per 350 to 600 miles. AdBlue® use is also usually around 3 to 6% of diesel consumption.

How do I reset my AdBlue warning?

Usually to reset the AdBlue warning light it is sufficient to add more additive and reset the computer by turning the key to the on position for 30 seconds (without starting the engine, just turning the key), turning it off and waiting another 30 seconds.
