My DEF doesn’t consume or it stays full even though I drove more than 5,000 miles.the def tank doesn’t consume since I started using an anti gel additives.since December 2018 t haven’t filled up my DEF tank because it stays full.but now, winter is almost over I don’t use diesel additives anymore but instead I use shell diesel oil additives ( to eliminate/ minimize stiction problems).

Be sure to also follow equipment owners’ manuals and recommendations from your fuel provider.Īrticle by Rhys Eastham, Director – Uptime & Technical Services We developed this Diesel Exhaust Fluid (DEF) checklist for you and your operators to print out and reference to help avoid these mistakes. DEF tanks can build condensation, and that water can lead to contamination. It’s good practice to top off the DEF tank at the end of day. If the DEF tank is empty, the dashboard indicator light will illuminate and the engine will de-rate after a period of time.Remember to change DEF filters regularly according to service intervals.To avoid running into storage issues, some operators prefer the 2.5-gallon container over bulk storage to prevent waste and potential contamination. DEF expands seven percent once it hits freezing temperature. If you are going to keep DEF somewhere cold, you will want an expandable container. The DEF will degrade over time but can last up to one year if stored between 12 and 86 degrees Fahrenheit.ĭEF will freeze at temperatures below 12 degrees Fahrenheit and could turn slushy, but that does not impact quality or performance. A cool, dry location indoors is preferred. You want to store the DEF out of direct sunlight and in stainless steel or plastic totes as directed by the manufacturer. DEF is just too sensitive to contamination. Also make sure they know not to use containers that may have been used for other materials or fluids, even if they’ve been cleaned DEF should be stored in dedicated containers. These hassles and associated costs can be avoided by simply talking to your operators and maintenance staff to ensure they know how incredibly important it is to clean around the cap before pouring in the fluid. Some signs this ratio may be off and your DEF is contaminated includes an uptick in DEF consumption, the selective catalytic reduction (SCR) system malfunctions or the engine starts shutting down. The ideal concentration is between 32.5 and 37 percent urea. The best way to test and monitor the concentration of urea-based DEF is to use a digital refractometer. This can cause serious contamination-related issues - and cause unplanned downtime. If the area around the tank and cap isn’t cleaned before the cap is undone and fluid is added, it’s very easy for dirt or dust to fall in and get washed down into the tank. Contaminants around the fill cap can make their way into DEF and cause damage as well. Your dealer can walk you through the steps to avoid unnecessary damage and the associated costs.ĭEF is extremely sensitive to contamination - for it to work properly, purity is critical. To avoid running up excessive repair bills, talk to your operators and be sure they know to immediately contact you and your Volvo equipment dealer if they accidentally added DEF to the fuel tank. If you are ever in doubt if the correct fill hole was used, drain and flush the tank with deionized water or clean DEF fluid. Usually, the DEF fill hole is smaller in diameter. If you have machines where the DEF and diesel tanks are near each other, another easy way to tell the difference is the size of the fill holes. If that happens, and an operator starts a machine with DEF in the fuel lines, it can potentially cause tens of thousands of dollars in damage. But fuel and DEF tanks are close in proximity on some pieces of construction equipment, so it’s not surprising this mistake occurs. The liquid, which looks like water, is sprayed into the exhaust before it exits the machine.ĭEF should never be mixed with diesel fuel, and it has its own filling port.

Here’s my advice on how to avoid them.ĭiesel exhaust fluid is an emissions control solution designed to lower the nitrogen oxide emissions in diesel engines.
