Diesel is also often dyed red or blue in the United States to indicate that it is tax-free. You said you put some in your vehicle as well. Red dyes are often various diazo dyes, e.g., Solvent Red 19, Solvent Red 24, and Solvent Red 26. So basically is the older petrol darker because its older? is one petrol and one diesel - is one dodgy petrol ? Currently there are no naked-eye visible dyes in car fuels sold in Poland.

The longer branched side chains improve solubility dramatically, but in some cases the high solubility prevents the dye being isolated as a crystal, except at very low temperatures. (N-ethyl-1- (4-fenilazofenilazo) naphthyl-2-amine – at least 5.0 grams; This page was last edited on 23 September 2020, at 18:57. [11] In 2009, customs officials shut down a plant capable of removing the dye from 6.5 million litres of fuel per year. As red diesel is widely available in the UK, the authorities regularly carry out roadside checks. It can be easily detected in the fuel at levels as low as 0.3 ppm by extraction to a diluted hydrochloric acid, allowing detection of the red diesel added into motor diesel in amounts as low as 2–3%. That way im never using stale fuel for my bike or mower. The old mower with briggs and stratton motor loved it, just seemed to run much smoother. It looks more like diesel, and smells a bit like it as well. 17354-14-2) or any other equivalent blue coloring - at least 7.0 grams on 1000l. However, many people are not aware of the difference between petrol and diesel though they are aware of their price difference and the mileage that these two different petroleum … If you used the black dispenser at BP then you got diesel. I have a gull handy to me, and used to go to gull all the time until they went bio.Now I don't touch it. [13], Fuel is being dyed by companies such as Bord na Móna in Ireland in an effort to combat the widespread theft of fuel.[14]. Anthraquinone dyes are used for green and blue shades, e.g., Solvent Green 33, Solvent Blue 35 and Solvent Blue 26. BASF created Solvent Blue 79 as its high solubility form of Solvent Blue 35. The used chemical substance is N-ethyl-N- [2- (1-iso butoxyethoxy) ethyl] azobenzene-4-amine (Solvent Yellow 124). Petrol and diesel are petroleum-derived liquid mixtures used as fuels. Shane ( OP), put about a litre of it in a coke bottle or a clear bottle, with the lid on, shake the f==k out if , if it is diesel it will foam on the top and the foam will stay for a few seconds ( BP, Gas Alley, diesel is green coloured), if it is petrol you will be working hard to get a foam of any size ad it will collapse almost as fast as you stop shaking it. Low-tax dyed fuel oil (Finnish: polttoöljy; Swedish: brännolja; always abbreviated on nozzles as MPÖ), is available in many rural petrol stations in Finland, primarily intended for certain types of non-road vehicles such as tractors and driveable construction vehicles. The Internal Revenue Service regulation 26 C.F.R. Organised crime gangs may "launder" low-price dyed fuel, removing the dye and selling it illegally to unsuspecting motorists at the higher price of undyed fuel. The petrol companies add a dye into the petrol so they can tell which grade is which. 91 octane is light pink/red and 95 octane is light gold/brown and diesel is almost clear but frothy,not sure what colour 98 octane is though. The key difference between petrol and diesel is that the petrol contains lighter hydrocarbons whereas the diesel contains heavy hydrocarbons. any red dye + Solvent Yellow 124: Orden PRE/1724/2002 of the 5th of July. I buy 5 litres in a container, mow my lawns then empty the container into my bike. In some cases it is possible, with normal solvents—e.g., xylene—to prepare stable (to -20C) solutions at 65% "solids" content. The European Union has announced that has found a new and better marker to replace Solvent Yellow 124. ^It's the aromatics that go off in petrol though isn't it! with petrol you know it is by the smell and the way it evaporates rapidly, its the fumes that ignite not a liquid itself but with diesel its mostly the liquid that that is flammable and takes a very long time to evaporate. [12] In 2011, a plant capable of processing 30 million litres was discovered. any blue dye + Solvent Yellow 124: Orden PRE/1724/2002 of the 5th of July. When I dipped a stick into it then went and lit it it didnt ignite like ordinary petrol.no whoomp and burning more of a slow ignite. The dyes used have to be soluble in the fuels they are added to and therefore in hydrocarbon-based nonpolar solvents ("solvent dyes"). The high solubility liquid dyes originated with Morton International and BASF (ACNA Italy) as the primary inventors. Fuel dyes are dyes added to fuels, as in some countries it is required by law to dye a low-tax fuel to deter its use in applications intended for higher-taxed ones. Unauthorised use incurs heavy fines but despite this, spot checks have occasionally found as many as one in five motorists using red diesel. Detection of red-dyed fuel in the fuel system of an on-road vehicle will incur substantial penalties. Yeah stupid question but does anyone know the colour of 95 octane bp petrol! In 2004, Northern Irish police discovered an illegal facility capable of removing the dye from 12 million litres of fuel per year. Paramilitary groups connected to political unrest in Northern Ireland have established laundering plants on both sides of the Irish border. tags | The pure dyes found in modern liquid petroleum dyes are essentially longer alkyl side chain forms of traditional dyes and normally multiple chain length variations of the chromophore are found within a typical commercial liquid petroleum dye. Until 2002, furfural was used to dye fuel oil in Finland, when it was replaced with Solvent Yellow 124. In the United States of America, the Environmental Protection Agency mandates use of a red dye to identify fuels for off-road use. The more aromatics to start with the staler the petrol later. 48.4082-1 mandates use of the same red dyes, in fivefold concentration, for tax-exempt diesel fuels such as heating oil; their argument for the higher dye content is to allow detection even when diluted with "legal" fuel. Try 100 octane.mower runs even better than on 95 & smells great! Some dyes required in some countries are listed here: Diesel is labeled by adding one of the coloring matters to 1000 liters of oil products:: "Purple gas" redirects here. It is marketed as an environmentally friendly alternative to regular red diesel. ), fiscal marker - chemical N-ethyl-N- [2- (1-isobutoxyethoxy) ethyl] -4- (phenylazo) aniline (Solvent Yellow 124, CAS Nr.34432-92-3) - at least 6.0 grams, and no more than 9.0 grams; on 1000l, blue colorant 1,4-bis (butylamino) -9,10-anthraquinone (Sovlent Blue 35, CAS no. [8], On 18 November 2014, a new measure to combat fuel laundering should result in the illegal trade being "virtually eliminated" in the United Kingdom, according to HM Revenue and Customs. The scheme, which is based on a model used in Paris, entails using two types of stickers to distinguish between vehicles that run on petrol, CNG and … Welcome back Jazzz - I wondered where you had been.i see your point but I just use 91 in my B&S mower and it sits around for weeks- I'm lazy when it comes to lawns and it starts first pull. what's popular | [1][2][3][4][5][6][full citation needed], In the United Kingdom, "red diesel" is dyed gas oil for registered agricultural or construction vehicles such as tractors, excavators, cranes and some other non-road applications such as boats. Red diesel carries a significantly reduced tax levy compared to un-dyed diesel fuel used in ordinary road vehicles. Diesel (black) and dyed fuel oil (MPÖ; red) dispensers at a St1 petrol station in Tornio, … [9], Carbon offset red diesel is, as of 2014, available in the UK. BP98 is yellow, almost the same as yellow powerade, It's the modern high compression that requires it. Also, is the pump you used now closed with tape all over it and a bunch of worried looking BP staff working on it! get in touch. This dye can be easily hydrolyzed with acids, splitting off the acetal group responsible for its solubility in nonpolar solvents, and yielding a water-soluble form. Since 2008, boats and pleasure craft are no longer legally allowed to use low-tax fuel oil, instead taxable diesel must be used for fuel. lol sorry for the essay There is an extra cost incurred when purchasing carbon offset red diesel, however some[clarification needed] suppliers of the fuel are donating the extra cost to projects aimed at lowering carbon emissions, meaning they make no extra profit from the sale of the fuel.[10]. Only a few refineries worldwide still use powder dyes for colouring fuels, as ultimately they are still lower cost per active molecule of dye chromophore than the modified forms. If it looks like oil,smells like oil, and feels like oil, then it probably is. It's the ethanol reacting with moisture in the air I thought! Definately used the yellow pump not the black one, There is no pink tinge to it it is kinda very light brown, was wondering if there has been a snafu when the tanker came and filled their tanks!
