But how?<\/p>\n\n\n\n<h3 id=\"type-of-gasoline\" class=\"wp-block-heading\">Type of Gasoline<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">There are two main types of gasoline sold for your car&rsquo;s tank: <strong>pure gasoline and ethanol-blended gasoline.<\/strong> Pure gasoline has an extended shelf life&ndash;but maybe not as extended as you think.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Ethanol-free gas can last 3-6 months<\/strong> because it doesn&rsquo;t absorb water or humidity. And that&rsquo;s what helps prevent predicaments like <strong><em>moisture contamination and fuel separation.&nbsp;<\/em><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ethanol-blended gas is great for enhancing fuel performance, but ethanol is known for attracting water molecules from the atmosphere, translating to a <strong>storage shelf life of about three months.&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><img  decoding=\"async\"  width=\"624\"  height=\"417\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-pk-src=\"https:\/\/lh7-us.googleusercontent.com\/Gds4UwEh7D4NXtiet2IcLScysTxgxVJOD0a_v9Z7vHIykUsvByz9isMHRHrnwCaFuixArh-OIi9zyQ9PZNiV3ng0v5iZI970bIb64DE-T2QHGC5b3Xy6wb6udXgzNVVQffWD9JLcWCCDsOSrJRMb_40\" ><\/strong><\/p>\n\n\n\n<h3 id=\"storage-conditions\" class=\"wp-block-heading\">Storage Conditions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An ideal environment for gasoline is a securely <strong>sealed container in a cool, dry, and low-oxygen setting.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Storing in sealed containers <strong>prevents the evaporation of volatile compounds and reduces the risk of contamination<\/strong>. A cool, dry environment also minimizes the chances of water <em>contamination<\/em> and <em>corrosion<\/em> of the fuel system components.<\/p>\n\n\n\n<h3 id=\"temperature-fluctuations\" class=\"wp-block-heading\">Temperature Fluctuations<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Severe temperature fluctuations<\/strong> can also significantly impact the lifespan of gasoline. Storing gas during periods of extreme temperature fluctuations <em>(the transition from summer to winter)<\/em> can lead to degradation. In the same way, extended exposure to extreme hot or extreme cold can make gasoline spoil faster. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But here&rsquo;s another potential surprise related to weather &ndash; <strong><em>did you know <\/em>that unique gas <em>blends are produced in the summer and the winter?<\/em> And for good reason.<\/strong> Summer gasoline contains heavier hydrocarbons. Winter fuel comprises lighter hydrocarbons, which evaporate more quickly. For this reason, <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you head to the gas station in the summer and use this stored gasoline to fuel your winter ride, you may start to have engine trouble.&nbsp;<\/p>\n\n\n\n<h3 id=\"identifying-bad-gasoline-in-your-cars-gas-tank\" class=\"wp-block-heading\"><strong>Identifying Bad Gasoline in Your Car&rsquo;s Gas Tank<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you have old gas in your car that you think may have gone bad, you&rsquo;ll want to check the following: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The smell<\/li>\n\n\n\n<li>The color&nbsp;<\/li>\n\n\n\n<li>The consistency<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Fresh gas has a distinct and strong odor, while <strong>bad fuel emits a <em>sour or stale smell<\/em><\/strong><em>.<\/em> If it smells off, don&rsquo;t ignore it.

Using <strong>fresh gasoline<\/strong> in your car is considered the best practice.&nbsp; However, there are ways to extend the lifespan of the gas in your car, should you need to store your vehicle or leave it unattended for extended periods of time. <\/p>\n\n\n\n<h3 id=\"using-fuel-stabilizers\" class=\"wp-block-heading\">Using Fuel Stabilizers <\/h3>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Fuel stabilizers are petroleum-based additives that can be added to gasoline to slow the oxidation and evaporation processes. Using fuel-stabilized gasoline can effectively reduce the rate these chemical reactions occur, chemical reactions that lead to gasoline degradation.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To use a fuel stabilizer, simply add the recommended amount to your gas tank and drive your car for a short period to ensure the additive circulates throughout the fuel system.<\/p>\n\n\n\n<h3 id=\"proper-storage-techniques\" class=\"wp-block-heading\">Proper Storage Techniques<\/h3>\n\n\n\n<ol class=\"wp-block-list\" start=\"2\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Proper storage techniques play a significant role in extending gasoline&rsquo;s shelf life. <strong>Keeping the gas tank full<\/strong> can help reduce the amount of air in the tank, minimizing the chances of moisture entering the system. Additionally, storing your car in a cool, dry environment can further prevent moisture contamination and corrosion.<\/p>\n\n\n\n<h3 id=\"observe-good-driving-habits\" class=\"wp-block-heading\">Observe Good Driving Habits <\/h3>\n\n\n\n<ol class=\"wp-block-list\" start=\"3\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Your driving habits can also influence the longevity of gasoline in your car&rsquo;s fuel tank. Regularly driving your car can help prevent gas from degrading through the power of circulation. <em><strong>Note that extended periods of inactivity can deteriorate gas quality.<\/strong><\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Allowing your car to <em>remain idle for prolonged periods, driving aggressively, and engaging in frequent short trips or stop-and-go traffic<\/em> can all <strong>negatively impact gasoline shelf life.&nbsp;<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img  decoding=\"async\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-pk-src=\"https:\/\/lh7-us.googleusercontent.com\/QvfsjvAe3go2P03dtCjasuwHVL8GnpqdU67dKg9IY2UqCsY1P7jXq5dV9sx5VcHS_FaFy2H4EXi87p9ttX1PTLZ3dqrzNV50EtY1utRf-njFo4xpE4mAcVjOmUz1T0t1mkUtLJ6Od_pMXI8qxe5vNrA\" ><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Source: <\/strong><a href=\"https:\/\/pixabay.com\/photos\/gasoline-gas-can-petrol-fuel-tank-2501302\/\" target=\"_blank\"><strong>Pixabay<\/strong><\/a><\/p>\n\n\n\n<h2 id=\"how-to-dispose-of-old-gasoline-safely\" class=\"wp-block-heading\">How to Dispose of Old Gasoline Safely <\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Contact your local waste management or fire department for approved disposal sites of old gasoline. These will include <a href=\"https:\/\/www.epa.gov\/hwgenerators\/links-hazardous-waste-programs-and-us-state-environmental-agencies\" target=\"_blank\">Household Hazardous Waste Facilities<\/a> or <a href=\"https:\/\/www.epa.gov\/hwpermitting\/how-do-i-find-hazardous-waste-management-facilities-my-area\" target=\"_blank\">local hazardous waste disposal centers<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These facilities are equipped to handle old gas and ensure its safe disposal, preventing potential environmental and safety hazards. Do not throw old gas in the trash.<\/p>\n\n\n\n<h2 id=\"final-thoughts\" class=\"wp-block-heading\">Final Thoughts<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">So, how long can gas sit in a car safely? The answer is <strong>about 3&ndash;6 months<\/strong>, and that&rsquo;s <em>if<\/em> you also abide by the safety guidelines. The chemical properties of gas effectively cap its shelf life. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It may seem like a good idea to funnel gas into a storage container and save it for later in the year when prices hit record highs. But it&rsquo;s not a wise choice when considering the average shelf life of stored gasoline.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The good news is that we&rsquo;re largely in control of how we treat our cars&ndash;a lot of that involves proper car storage when traveling, relocating, or decluttering. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most gasoline will stay fresh for a few months if we properly store our cars when not in use. If you don&rsquo;t have access to a temperature-controlled home garage, finding an alternative storage option is a must. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Luckily, there are options like <a href=\"https:\/\/www.neighbor.com\/car-storage-near-me\">Neighbor<\/a>, which can help you find a person near you with extra storage space for you to park your ride.<\/p>\n\n\n\n<h2 id=\"frequently-asked-questions\" class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 id=\"does-gas-sitting-in-a-car-go-bad-how-long-does-gas-really-last\" class=\"wp-block-heading\">Does Gas Sitting in a Car Go Bad? How Long Does Gas Really Last?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, allowing gas to sit idle in a car&rsquo;s fuel tank leads it to degrade within a few months. Regular gasoline can last 3&ndash;6 months.<\/p>\n\n\n\n<h3 id=\"can-i-mix-old-gas-with-new-gas\" class=\"wp-block-heading\">Can I Mix Old Gas With New Gas?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Mixing old and new gas should be avoided, as this will reduce its combustibility, leading to possible sputtering issues.<\/p>\n\n\n\n<h3 id=\"can-i-put-old-gas-from-a-plastic-container-in-my-gas-tank\" class=\"wp-block-heading\">Can I Put Old Gas From a Plastic Container in My Gas Tank?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Even old gas from a sealed container will, eventually, go bad. While it may suffice for a lawnmower or snowblower, it&rsquo;s best to keep bad fuel out of your vehicle&rsquo;s tank.<br><\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"Do you have a car in your garage or storage facility that you haven&rsquo;t taken for a drive&hellip;\n","protected":false},"author":41,"featured_media":11000,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"csco_singular_sidebar":"","csco_page_header_type":"","csco_appearance_grid":"","csco_page_load_nextpost":"","csco_post_video_location":[],"csco_post_video_location_hash":"","csco_post_video_url":"","csco_post_video_bg_start_time":0,"csco_post_video_bg_end_time":0,"footnotes":""},"categories":[196],"tags":[],"class_list":["post-10999","post","type-post","status-publish","format-standard","has-post-thumbnail","category-personal-cars","cs-entry","cs-video-wrap"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v21.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>How Long Can Gas Sit in a Car Before it Becomes Unusable? - Neighbor Blog<\/title>\n<meta name=\"description\" content=\"Ethanol-free gas can last 3-6 months, as it doesn&#039;t absorb water or humidity.
