Since 2010, virtually all on-road diesel trucks and many off-road diesel machines have used DEF as part of these systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SCR systems can monitor DEF levels and generate alerts when supplies are low, depending on the vehicle or machine\u2019s design. If DEF runs out and the situation is not corrected, the vehicle\u2019s behavior will depend on the manufacturer and the system installed. Some systems may <strong>significantly reduce speed or limit operation<\/strong> until the condition is resolved.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"600\" height=\"400\" src=\"https:\/\/americanpetroleumpr.com\/wp-content\/uploads\/AQL-Diesel-Exhaust-Fluid.jpg\" alt=\"AQL Diesel Exhaust Fluid\" class=\"wp-image-35990\" srcset=\"https:\/\/americanpetroleumpr.com\/wp-content\/uploads\/AQL-Diesel-Exhaust-Fluid.jpg 600w, https:\/\/americanpetroleumpr.com\/wp-content\/uploads\/AQL-Diesel-Exhaust-Fluid-300x200.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">For a transportation fleet, this can result in downtime, route delays, and additional operating costs. For equipment used in critical operations, ensuring DEF availability is also part of supply planning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, incorporating DEF consumption into the regular refueling schedule can help prevent low levels that affect operations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How much DEF does your fleet consume? How to calculate and plan your supply<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Monthly Diesel Fuel Consumption<\/strong><\/td><td><strong>Estimated DEF at 3%<\/strong><\/td><td><strong>Estimated DEF at 5%<\/strong><\/td><\/tr><tr><td>500 gal\/month<\/td><td>500 gal\/month<\/td><td>500 gal\/month<\/td><\/tr><tr><td>15 gal\/month<\/td><td>15 gal\/month<\/td><td>15 gal\/month<\/td><\/tr><tr><td>25 gal\/month<\/td><td>25 gal\/month<\/td><td>25 gal\/month<\/td><\/tr><tr><td>1,000 gal\/month<\/td><td>1,000 gal\/month<\/td><td>1,000 gal\/month<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">DEF consumption varies depending on the equipment, environment, operation, and duty cycle. As a reference, Cummins notes that DEF consumption can account for approximately 3% to 5% of fuel consumption in certain SCR applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To make an initial estimate, you can use this formula: <strong>Estimated DEF consumption = diesel consumption \u00d7 3%\u20135%<\/strong><\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Frequently Asked Questions about DEF for commercial fleets in Puerto Rico<\/h1>\n\n\n\n<h3 class=\"wp-block-heading\">Which vehicles in my fleet require DEF?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Diesel vehicles and equipment equipped with SCR systems<\/strong> and for which the manufacturer specifies the use of DEF require this fluid as part of the emissions control system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How often does a freight truck need to have its DEF replenished?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The frequency depends on the size of the DEF tank, diesel consumption, the duty cycle, and operating conditions. As a reference, <strong>DEF consumption can account for approximately 3% to 5% of diesel consumption<\/strong> in certain SCR applications.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"600\" height=\"380\" src=\"https:\/\/americanpetroleumpr.com\/wp-content\/uploads\/Diesel-Exhaust-Fluid.jpg\" alt=\"Diesel Exhaust Fluid\" class=\"wp-image-35988\" srcset=\"https:\/\/americanpetroleumpr.com\/wp-content\/uploads\/Diesel-Exhaust-Fluid.jpg 600w, https:\/\/americanpetroleumpr.com\/wp-content\/uploads\/Diesel-Exhaust-Fluid-300x190.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Does DEF expire?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. DEF has a limited shelf life that depends on storage conditions. The API states that, under optimal conditions, <strong>it can last 12 months or longer<\/strong>, while high temperatures and direct exposure to sunlight can accelerate its degradation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does American Petroleum deliver DEF along with diesel and lubricants?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>American Petroleum distributes AQL Diesel Exhaust Fluid, in addition to <a href=\"https:\/\/americanpetroleumpr.com\/en\/diesel-in-puerto-rico\/\" target=\"_blank\" rel=\"noreferrer noopener\">diesel<\/a> and <a href=\"https:\/\/americanpetroleumpr.com\/en\/lubricants-in-puerto-rico\/\" target=\"_blank\" rel=\"noreferrer noopener\">lubricants<\/a><\/strong>, with various delivery options for business operations.
