Unfortunately, diesel can turn into gel at certain conditions, which is one of the last things you want to happen.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Is Your Diesel Fuel Gelling?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Just like water turns to ice when it&rsquo;s freezing, diesel turns into gel when it&rsquo;s exposed to cold temperatures. Diesel contains a waxy substance called paraffin, which can solidify and cause the fuel to turn into a thick, sludgy gel that won&rsquo;t flow well through your fuel pump, fuel lines, and fuel injectors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Temperature Does Diesel Gel?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Diesel typically turns to gel when constantly exposed to low temperatures of 10 to 15&deg;F, but issues can arise as soon as the temperature drops to 32&deg;F.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ultimately, how fast your fuel gels and at what temperature will depend on the source and quality of your fuel. For example, biodiesel fuel gels at higher temperatures than conventional diesel.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can Diesel Freeze While Driving?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The simple answer is yes. <a href=\"https:\/\/www.carparts.com\/blog\/diesel-engines-how-do-they-work-and-why-do-they-last-so-long\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Diesel\">Diesel<\/a> can still gel even if your vehicle is running smoothly. While the engine certainly runs hot and warms up other parts of your vehicle, it isn&rsquo;t always enough to stop your fuel from gelling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In most vehicles, the fuel tank is located far from the engine, where the warmth of the engine won&rsquo;t be able to do much.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms of Gelled Diesel<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you live in an area with a cold climate, then it&rsquo;s only natural to worry about your diesel fuel suddenly turning to gel. Fortunately, you don&rsquo;t have to constantly worry because there are a few signs that&rsquo;ll tell you whether or not your fuel is gelling, such as the following:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Engine Won&rsquo;t Start<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Dealing with an <a href=\"https:\/\/www.carparts.com\/blog\/my-car-wont-start-what-should-i-do\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"engine that refuses to start\">engine that refuses to start<\/a>? You might have gelled diesel in your tank. When diesel fuel gels, it can clog the fuel lines and fuel filter, effectively blocking fuel from passing through to power the engine.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Sluggish Performance<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Has your vehicle felt sluggish in the cold? If the answer&rsquo;s yes, then there&rsquo;s a big chance that your diesel fuel is starting to gel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When your fuel tank&rsquo;s temperature drops low enough, diesel will start to thicken and cause your vehicle to feel sluggish and accelerate slowly.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n<input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">How To Ungel Diesel Fuel<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you&rsquo;re dealing with gelled diesel fuel, then you&rsquo;re going to want to address the issue as soon as possible, especially since you likely won&rsquo;t be able to use your vehicle until you do. Here are some tips to fix your gelled fuel:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Replace Your Fuel Filter<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your diesel fuel has turned to gel, it&rsquo;s likely reached other places too. After inspecting your fuel tank, check on your fuel filter for gel-like particles too. You might have to <a href=\"https:\/\/www.carparts.com\/blog\/how-to-replace-a-fuel-filter\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"replace it\">replace it<\/a> and drain your vehicle&rsquo;s water separators as well.&nbsp; Make sure to wear thick safety gloves to protect your skin from the bacteria that can grow in diesel fuel.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Use a De-Gel Product<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Your best bet to fixing gelled fuel is going to a mechanic. If you&rsquo;re too busy to drop by one, you can try using a de-gel product first. Be sure to buy a de-gel product and not an anti-gel product since the latter won&rsquo;t work on already gelled diesel.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How To Prevent Fuel From Gelling<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dealing with gelling fuel can be a hassle, which is why it&rsquo;s a good idea to do everything you can to prevent it. Here are some tips on how to prevent your diesel fuel from gelling:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Use Winterized Diesel<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can ask your local gas station if they have winterized diesel. Not every gas station will have it, but some have a type of diesel fuel with a lower gelling temperature.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Use Anti-Gel Additives<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can also try using cold flow improvers or anti-gel additives to prevent your diesel fuel from gelling over the winter. Anti-gel additives are different from de-gel products, which you add after the diesel has solidified.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cold flow improvers are meant to prevent your diesel fuel from gelling, so you&rsquo;ll have to add them while your fuel is still liquid.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Park Your Vehicle in the Garage<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Leaving your vehicle outside when it&rsquo;s cold increases the chances of your diesel fuel gelling, so if you can, keep your vehicle parked in your garage or an indoor parking lot as much as possible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Use an Engine Block Heater<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can also invest in an engine block heater, an electrical device you plug into your engine to keep it warm even when you aren&rsquo;t using your vehicle. You can purchase one specifically fitted to your vehicle at your local dealership.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Keep Your Fuel Tank Full<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Having more fuel in the tank makes it less likely for water or condensation to collect and cause your diesel to gel. It&rsquo;s best to keep your fuel tank as full as possible, but keeping it at more than half full should be good enough.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Get a Fuel Filter Replacement For Your Vehicle Online<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When diesel turns to gel, you might need to replace your vehicle&rsquo;s fuel filter so that its fuel system will function properly again. You can likely get a new fuel filter at a brick-and-mortar store, but it might be a hassle to travel a long way and then wait in line just to buy a part.
