== Misleading diesel fuel definition ==

<hr>

I think it is misleading to define diesel as "any liquid fuel used in diesel engines". Most marine engines are also diesel engines but they are not build to use diesel fuel instead they use Heavy Fuel Oil-s like RMB, IFO or MGO http://www.wartsila.com/products/marine-oil-gas/engines-generating-sets/diesel-engines

Could this be fixed up so that the [[Diesel]] page becomes the one for disambiguation, and the content for that page goes to [[Diesel fuel]] (eliminating the redirect there)?

<br />

All EU countries define diesel by distillation curve.<br />

Please see the difference in gas oil and fuel oil:<br />

"(e) ‘gas oils’ (subheadings 2710 19 31 to 2710 19 48 and 2710 2011 to 2710 2019) mean heavy oils as defined in paragraph (d) above of which 85% or more by volume (including losses) distils at 350 C (ISO 3405 method (equivalent to the ASTM D 86 method);<br />

(f) ‘fuel oils’ (subheadings 2710 19 51 to 2710 19 68 and 2710 2031 to 2710 2039) mean heavy oils as defined in paragraph (d) above (other than gas oils as defined in paragraph (e) above) which, for a corresponding diluted colour C, have a viscosity V:<br />

These provisions apply only to oils having a diluted colour C of less than 2."<br />

I suggest to define diesel as any distilled gas oil used in diesel engine. Diesels is similar to light fuel oil, not to the heavy fuel oil used in central heating plants. Light fuel oil is mostly used for domestic heating. <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/90.191.76.230|90.191.76.230]] ([[User talk:90.191.76.230#top|talk]]) 21:42, 4 December 2016 (UTC)</small> <!--Autosigned by SineBot-->

:This article is a mess. It's going to take a major re-write to fix it. The basic problem I think is that many people think "diesel fuel" is whatever you put in to the tank of a diesel engine, but to an engineer or chemist, diesel fuel is a petroleum distillate with a particular fraction profile, perhaps with some additives. This article can't decide which definition to use. Compounding the problem is that the section on "real" diesel fuel, "Petroleum diesel", is by far the shortest. The Biodiesel section is way longer despite there already being a separate article on biodiesel.

"Diesel fuel" is more often than not incorrect grammar - thus the current organization. I have fixed the links to point directly to the fuel. --[[User:Maveric149|mav]]

:Fixing this will take more than just tweaking a few words in the lead. Since the article uses the vernacular definition that includes both petro- and bio- diesel, we can't contradict that in the lead. [[User:Kendall-K1|Kendall-K1]] ([[User talk:Kendall-K1|talk]]) 22:38, 4 December 2016 (UTC)

== Different Types of Diesel Fuel at Gas Stations ==

Pumps usually offer two type of diesel fuel. PLease would someone knowledgable add information about what the difference is ? Many Thanks ! [[User:Darkman101|Darkman101]] ([[User talk:Darkman101|talk]]) 01:34, 1 September 2021 (UTC)

:That depends upon the petrol station where you're getting the fuel. I suppose you're in the US, and in the US the ASTM D975 standard is used. There are two categories of road-vehicle fuel according to this standard, No. 1-D and No. 2-D. The key difference between these fuels is the volatility; No. 1-D fuel is basically better suited for low temperatures. In Europe on the other hand the Euronorm 590 standard applies. This standard allows a certain range of different fuels, because it only limits the physical properties of the fuel. Most importantly, it specifies the density (0.820...0.845&nbsp;kg·dm^&minus;3). Typically, bog-standard diesel fuel complies with this standard, but has some disadvantages, namely the poor ignition characteristics (>51&nbsp;CN). An ideal Diesel engine fuel with good ignition characteristics consists only of [[alkanes]] that are lighter than what the standard allows (>80&nbsp;CN). Therefore, an ideal Diesel engine fuel cannot be sold as "diesel fuel" across Europe. However, it is possible to mix bog-standard diesel fuel with alkanes in a way that the resulting fuel blend still complies with the EN 590 standard (>60&nbsp;CN). This means that "officially" there is only one type of fuel; in practice though, these optimised fuels are often sold as performance fuels (Shell V-Power or Aral Ultimate). Due to their much better ignition characteristics these fuels perform better during winter. Fuel is typically mixed with anti-gel agents during winter, so there is no need to buy "special winter fuel" (=all diesel fuels sold during winter are winter fuels).

::Thanks for your reply. I am in the UK, where many fuel pumps have "Diesel" and "Premium Diesel".

::I cannot find any clear reliable source of information that will tell me if the extra price will really give me more miles per gallon. [[User:Darkman101|Darkman101]] ([[User talk:Darkman101|talk]]) 13:32, 10 July 2023 (UTC)

== Fatty acids ==

This sentence is misleading:"Biodiesel is obtained from vegetable oil or animal fats (biolipids) which are mainly fatty acid methyl esters (FAME), and transesterified with methanol."

Biolipids are esters of propan-tri-ol (glycerine) and fatty acids, not methyl esters.

They become FAME through transesterification. [[Special:Contributions/153.100.134.67|153.100.134.67]] ([[User talk:153.100.134.67|talk]]) 14:08, 16 January 2024 (UTC)

== "Otto" engine ==

it would be useful to link to [[Otto engine]] to clarify. [[Special:Contributions/142.163.195.114|142.163.195.114]] ([[User talk:142.163.195.114|talk]]) 14:48, 15 March 2024 (UTC)

== "1911 World's Fair in Paris" possible falsehood ==

In the section [[Diesel fuel#Origins]] it mentions the "1911 World's Fair in Paris" which is mentioned in the source on Google Books, but a quick google search seems to show that there never existed a 1911 World's Fair in Paris.
