It has a lower tax duty and thus comes coloured red (leading to the name, red dye diesel) to help identify its usage by <a href=\"https:\/\/www.gov.uk\/guidance\/using-rebated-fuels-in-vehicles-and-machines-excise-notice-75#hmrc-powers-to-check-sample-and-test-fuel\" target=\"_blank\" rel=\"noreferrer noopener\">HMRC&#8217;s enforcement officers<\/a>.<\/p>\n\n\n\n<p>If a vehicle is suspected of using gas oil illegally, such as in vehicles used on public roads. The red dye will stain the fuel tank, giving away its prior use within the vehicle.<\/p>\n\n\n\n<p>You may hear people refer to the fuel as gas oil, but it is also known as <a href=\"https:\/\/www.crownoil.co.uk\/products\/red-diesel\/\">red diesel<\/a>, due to the colour of the dye that&#8217;s added to gas oil. There may also be times when you hear it referred to as 35-second oil, tractor diesel and agricultural diesel, which are some of the other more common names it often goes by. But gas oil and red diesel are the two most common names you&#8217;ll hear it being called.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-crownoil-content-spacer content-spacer\">\n<h2 class=\"wp-block-heading\" id=\"h-who-can-legally-use-gas-oil\">Who can legally use gas oil?<\/h2>\n\n\n\n<ul class=\"wp-block-list tick-list\">\n<li>Travelling fairs and circuses<\/li>\n\n\n\n<li>Fuel used for non-commercial purposes \u2013 electricity generation and heating<\/li>\n\n\n\n<li>Agriculture, horticulture, fish farming and forestry<\/li>\n\n\n\n<li>Rail transport<\/li>\n\n\n\n<li>Community amateur sports clubs and golf courses<\/li>\n\n\n\n<li>Sailing, boating and marine transport (excluding private pleasure craft in Northern Ireland)<\/li>\n<\/ul>\n<\/div>\n\n\n\n<div class=\"wp-block-crownoil-content-spacer content-spacer\">\n<h2 class=\"wp-block-heading\" id=\"h-can-you-legally-use-gas-oil-in-diesel-powered-vehicles-on-the-road\">Can you legally use gas oil in diesel-powered vehicles on the road?<\/h2>\n\n\n\n<p>As already stated, there are some restrictions and guidelines surrounding its usage, for instance, it is NOT&nbsp;a substitute for road diesel. Using it in a diesel-powered vehicle on a <a href=\"https:\/\/www.gov.uk\/government\/publications\/excise-notice-75-fuel-for-road-vehicles\/excise-notice-75-fuel-for-road-vehicles#fuel-which-may-be-used-in-road-vehicles\" target=\"_blank\" rel=\"noreferrer noopener\">public road is an offence<\/a>.<\/p>\n\n\n\n<p>Although it is considerably cheaper than regular diesel due to the lower tax duty, the potential fines or prosecution incurred from using gas oil illegally could be much higher than any savings made.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-crownoil-content-spacer content-spacer\">\n<h2 class=\"wp-block-heading\" id=\"h-where-does-gas-oil-come-from\">Where does gas oil come from?<\/h2>\n\n\n\n<p>Gas oil is commonly created from petroleum. It is a fossil diesel which is derived from the <a href=\"https:\/\/www.crownoil.co.uk\/guides\/crude-oil-fractional-distillation\/\">fractional distillation of crude oil<\/a>. When crude oil is added to a large chamber (fractionating column) and distilled in this way, the lower part of the chamber has a much hotter atmosphere, which cools as it rises to the upper part. At various height levels in the column, temperatures vary from the bottom to the top, whereby the atmosphere cools towards the upper part. There are several condensers fitted at different height levels, which\u00a0capture the vapours of different substances produced under the corresponding conditions.<\/p>\n\n\n\n<p>Gas oil is one of the heavier substances which are created and it is collected near the lower level of the column, just above marine fuel oil and just below aviation fuel. Below marine fuel oil, a substance called bitumen is produced, which isn&#8217;t suitable as fuel and is commonly used for road surfaces instead.<\/p>\n\n\n\n<p>The lower part of the fractionating column produces substances which have a higher boiling point and lower volatility, whereas towards the top of the chamber substances with a lower boiling point and higher volatility are produced.<\/p>\n\n\n\n<p>We explain more in our dedicated <a href=\"https:\/\/www.crownoil.co.uk\/guides\/crude-oil-fractional-distillation\/\">guide to fractional distillation<\/a>.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><a href=\"https:\/\/www.crownoil.co.uk\/wp-content\/uploads\/2015\/07\/A-Fractionating-Column.png\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" src=\"https:\/\/www.crownoil.co.uk\/wp-content\/uploads\/2015\/07\/A-Fractionating-Column-1024x768.png\" alt=\"Fractionating Column - How fuels and substances are made by fractional distillation - What is gas oil\/how is it made? | Crown Oil\" class=\"wp-image-43712\"\/><\/a><\/figure>\n<\/div>\n\n\n<p><strong>Click the image below to enlarge: An example of fractional distillation in the fractionating column.<\/strong><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-crownoil-content-spacer content-spacer\">\n<h2 class=\"wp-block-heading\" id=\"h-what-does-gas-oil-cost\">What does gas oil cost?<\/h2>\n\n\n\n<p>The price of gas oil is much cheaper than regular road diesel, which you pump into a diesel car because its purpose is for off-road use. The idea is to give relief to those using it for business rather than pleasure and recently, owners of pleasure craft, yachts and boats were refused the right to use gas oil for propulsion. Although gas oil can still be used onboard as fuel for light and heat.<\/p>\n\n\n\n<p>With daily changes to gas oil prices, it&#8217;s difficult to put an actual price on rebated fuel,&nbsp;however, as a rebated fuel supplier, we check against competitor&#8217;s prices daily to ensure&nbsp;our gas oil prices are the most competitive in the UK.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-crownoil-content-spacer content-spacer\">\n<h2 class=\"wp-block-heading\" id=\"h-where-can-gas-oil-be-purchased\">Where can gas oil be purchased?<\/h2>\n\n\n\n<p>You can buy gas oil from registered gas oil suppliers such as ourselves!
