If you pour DEF into your fuel tank and realize your mistake immediately, your fuel system needs to be flushed, and there may be some part repairs or replacements required just from the fluid having been there. If you don’t realize your mistake immediately and start your engine, you’ll realize your mistake almost immediately.

Why use stabilizers in car?
In addition to their importance in preventative care, it is normal for all types of stabilizers to be used as a corrective treatment in a variety of problems. The primary lubrication and cleaning qualities that come with in-use performance treatments can provide vehicle owners with a new way to enjoy their cars. After a treatment, the engine’s components should begin running smoother, which results in a strong decrease in friction. This prevents rough idles and hard starts, which can improve the longevity of the car itself. Fuel treatments can also help dissolve hard chemicals and components inside the vehicle, which results in a much easier future cleaning procedure.
What are additives in an engine?
Ultimately, the broad variety of definitions encompass two unique types of additives: those that are designed to benefit the engine while it is in use and those that are designed to keep the engine’s fuel functional while the vehicle is used irregularly or stored for extended periods of time. Treatments meant for active usage combine cleaning elements with stabilizing ones, keeping the oil inside the engine from gumming up the sensitive machinery. Storage systems are stabilizers that mix with the fuel to prevent the components from breaking down, which could result in long-term corrosion and damage to the engine itself. Many specialized systems are meant to prevent moisture from collecting and rust from developing, ultimately extending the life of the machine.
How to keep your engine running?
Though fuel treatments and stabilizers can play a critical role in improving the way the engine runs, it is crucial for all vehicle owners to invest in maintenance procedures to keep their engines running well. Numerous driving practices can help prolong the life of the engine and reduce the risk and frequency of breakdowns. Similarly, drivers may also take preventative steps to keep their engines safe by regularly visiting auto body shops. Through a quick tune-up, drivers can prevent the vast majority of problems that affect their engines. Just by staying proactive, it is possible for all drivers to keep their vehicles safe and functioning for years to come.

The catalytic converter uses various metallics to clean the pollutants further before exhaust exits the tailpipe. Not only does the diesel vehicle run cleaner, it also burns fuel more efficiently , which translates to better fuel economy.
What does DEF mean in diesel?
DEF stands for diesel exhaust fluid. If you’ve been driving diesels for years and haven’t heard of it, that’s because it’s relatively new. Starting in 2010, the Environmental Protection Agency required all new diesel engines to emit less nitrous oxide. One way manufacturers can meet that standard is to use selective catalytic reduction.
Is DEF right next to fuel filler?
The upside of this is that the filler is not right next to the fuel filler. The downside is that if you’re not familiar with what’s under your hood, you might think you’re supposed to add DEF to the fuel tank. DEF is a great automotive advance — it leads to cleaner diesel emissions and better fuel economy. Just be sure to keep it in the right tank.

WHAT SHOULD WE DO IF WE GET DEF IN OUR FUEL?
If you suspect you have DEF in your diesel’s fuel system, do not drive the vehicle and do not attempt to start the engine. Don’t even turn the key on, as this will energize the fuel system and could pump DEF-contaminated fuel into the rest of the fuel system. If the error is caught before the key is turned, the fix may be as simple as dropping the fuel tank and flushing it out. Have the vehicle towed or flat-bedded to a repair facility, and if you need to unlock the steering column, be sure to disconnect the batteries before turning the key in the ignition so that the pump doesn’t accidentally get activated. Make sure get your vehicle repaired right away, as DEF is corrosive and letting it sit in the fuel system can cause further damage.
Where does DEF go in a fuel tank?
16 Avoid DEF contamination—remember that DEF goes in the smaller filler hole with the (usually) blue cap marked DEF, not directly into the fuel tank. Most auto parts stores carry 1-gallon bottles and 2.5-gallon boxes of DEF. The 2.5-gallon boxes have a fill hose included. If using a 1-gallon bottle, be sure to use a clean funnel for your fill. DEF is sensitive to contamination and a dirty funnel can cause problems.
How to tell if your engine is DEF contaminated?
Early symptoms include hard starting, rough idle and smoking exhaust, and a DEF-contaminated engine may not start at all. The contamination can cause lines to rust, injectors to stick open and fail, and pump failure is also very likely. The recommend repair is to replace the entire fuel system, from tank to injectors.
What are the sources of contaminated fuel?
According to Ford, the most common sources of contaminated fuel are auxiliary vehicle-mounted tanks; local storage tanks; infrequently used fuel sources; and refueling errors (i.e. DEF or gasoline poured into the fuel tank).
What is diesel exhaust fluid?
In the September 2014 issue of Diesel World we talked about diesel exhaust fluid (DEF), which is used as an exhaust treatment in modern diesel emissions systems to reduce the levels of nitrogen oxide (NOx) in the exhaust. These systems exist on most modern diesel pickups, diesel cars, semi-trucks and farm equipment.
What happens when you inject DEF into exhaust?
When injected into the exhaust the DEF is converted into ammonia which then breaks down NOx turning it into nitrogen and water. 1 To service the entire fuel system on a Ford, it’s much easier to raise the body to gain access to the all the fuel systems parts.
