How often should I change the Def fluid in my engine?
Diesel exhaust fluid has to be replaced on a regular basis. Replacement intervals are tied to the fuel efficiency of your engine. Less efficient engines produce more exhaust gases, which require more DEF to treat. Typically, dose rates for a well-maintained heavy- or medium-duty truck engine will be between 2-3%.

Any DEF purchased at a truck stop or auto parts store will have a clearly labeled expiry date — using DEF past this date can cause performance issues and potential maintenance problems.
What is a DEF filter?
DEF filters help keep unwanted contaminant out of your SCR equipment. If DEF is not properly filtered, urea crystals and other contaminants gained during transport and storage can cause the SCR system to malfunction or not work properly. Using Fleetguard DEF filters will help you prevent plugged DEF dosing valves and enable the Cummins SCR equipment to reduce harmful NOx emissions as intended. The Fleetguard UF101 filter can be used on any 2010-2016 Cummins engine with an SCR system. For 2017 and newer Cummins engines, such as the X15, use the Fleetguard UF106 filter. For more information about DEF filtration for today’s engines, visit https://www.cumminsfiltration.com/DEF_Urea.
What is the DEF on a 2010 EPA engine?
A: All EPA 2010 engines with SCR are designed with a gauge that shows the DEF fluid level, similar to a fuel gauge. In addition, they are equipped with a system of flashing lights to alert the operator well in advance when the DEF tank is getting low on fluid. If the reservoir is not replenished with DEF and runs low, vehicle speed will be limited, but as soon as DEF is added, the engine will resume normal speed levels. A prudent measure would be to have a top-off gallon jug of DEF available on each piece of equipment with an EPA 2010 engine with an aftertreatment system.
Why is diesel exhaust fluid important?
Diesel exhaust fluid (DEF) plays an important role in moderating truck emissions and meeting EPA guidelines. As with any type of vehicle fluid, regular monitoring of DEF levels is an important part of ongoing maintenance. While checking diesel exhaust fluid levels isn’t a difficult job, there are factors that can complicate the issue.
What is diesel exhaust fluid?
Diesel exhaust fluid is required for a process called selective catalytic reduction (SCR). SCR works by diverting exhaust gases through a filter and then into a catalyst. There, the gases mix with DEF, which turns hazardous NOx emissions into a harmless mixture of nitrogen and water. Diesel exhaust fluid has to be replaced on a regular basis.

What are the pros and cons of DEF?
The only cons to DEF include the additional upfront cost to the truck, added nominal weight and some additional room to store an extra gallon of the fluid. The pros are better fuel economy, increased horsepower, more optimized combustion, fewer regenerations issues, less wear on the engine and in addition it only releases nitrogen and water vapor into the air.
How to tell the age of a def?
This date code will tell the exact date the batch was produced and subsequently the age of the bottle of DEF. One gallon containers have a laser code imprinted on the bottle. Larger 2-5 gallon tanks usually have a small date code imprinted on the label of the product. Larger drums of DEF fluid (55 gallons +) and totes (275-355 gallons) will have a larger label applied to the side or top of the drum. Reading a manufactures code can be a bit tricky and each one is a little bit different. Usually the first digit of the date code represents the batch number and the next 6 digits reflect the date the batch was filled at the factory.

BlueDEF Platinum, the company claims, is the purest DEF formula in the market. It is manufactured under ISO 22241 guidelines to ensure the highest product quality and is API registered, meeting or exceeding OEM specifications for diesel exhaust fluid.
Does Peak Coolant reduce DEF deposits?
Coincidentally, two weeks later the good folks at Old World Industries, the manufacturer of Peak Coolant and BlueDEF, contacted us about their new BlueDEF Platinum, a new formula that they claim significantly reduces harmful DEF deposits. If you have a diesel engine with a SCR system, you’re probably familiar with the filmy, white deposits left by DEF fluid if you’ve ever spilled it on your truck or on the ground. Imagine these white deposits in your DEF system building up over time, creating all sorts of problems. Having just forked out over $3,500 in expensive repairs, you’ll under understand why we were intrigued when we learned about this new product.
Can you repair a diesel with a SCR?
Apparently, these are common repairs for diesels with Selective Catalytic Reduction Systems (SCR’s) running DEF (basically all diesels built after 2010). This is because most DEF formulas leave harmful deposits that will eventually cause failures like ours (a bad—read old—batch of DEF can trigger a DEF limp mode as well). We were fortunate that our system lasted seven years before it had a major failure, but other diesel owners haven’t been so fortunate. Some have had to make similar repairs soon after their warranties expired.
What happens if DEF drops?
If the amount of DEF drops past a certain point, the computer will put your vehicle in reduced power mode. This keeps the emission levels at a safe and legal level but also cripples your ride’s performance. You may have to call for a tow if you still have a long way to go with no refill at hand.
How to keep diesel exhaust fluid light dormant?
It’s easy to keep the diesel exhaust fluid warning light dormant. Just keep the DEF tank topped regularly. Make a habit of regularly inspecting the amount of DEF remaining in the container and refill it as needed.
What is diesel exhaust fluid?
Sometimes called diesel emissions fluid, DEF helps break down toxic nitrogen oxide (NOx) in the exhaust gases from the engine. The fluid ensures that tailpipe emissions are cleaner and safer for human health.

Where is the def port?
In most pickups, the DEF filler port should be next to the filler opening for diesel fuel. Other diesel-powered vehicles may have it elsewhere. If you cannot find the DEF filler port in your vehicle, check your owner’s manual. Take the time to read up on the DEF refilling process; you don’t want to accidentally pour the wrong fluid into the fuel tank and contaminate your fuel.
