Talk:unleaded fuel

unleaded fuel
This looks to be completely sum of parts - fuel that is unleaded. Looking over the translations almost all of them seem to be either equally sum of parts, or translations of unleaded. Any languages that have a term for unleaded fuel that cannot be derived from the component parts can be dealt with as usage notes at the entry and sense labels at unleaded.

 * I am not sure whether this is relevant, but in the States at least cars have stickers or notices which read "unleaded fuel only". What is interesting about this is that they don't take unleaded propane or unleaded diesel, they mean unleaded gasoline.  If there are other fuels referred to as unleaded I am on board with deleting, if it is only ever gasoline then I think it is a keep, but we should change the definition to reflect that fact. -  00:36, 8 June 2010 (UTC)

 * This seems like one of those regulatory/legal definitions that BD2412 has advocated. (See ground beef.) Keep unless it turns out not to be one. DCDuring TALK 02:12, 8 June 2010 (UTC)
 * Perhaps keep if improved, per DaveRoss. Does it mean any fuel that's unleaded, or specifically unleaded petrol/gasoline. Mglovesfun (talk) 18:37, 8 June 2010 (UTC)

I've gone through the Code of Federal Regulations, and have found dozens of uses of "unleaded" in relation to fuel or gasoline, but only two instances of the phrase "unleaded fuel", both undefined requirements that unleaded fuel may or must be used in certain circumstances. The closest thing I found to a definition was in the EPA regulations:
 * 40 CFR § 79.32 Motor vehicle gasoline.
 * Motor vehicle gasoline, unleaded--motor vehicle gasoline that contains no more than 0.05 gram of lead per gallon.

Probably delete, per BD's results. < class="latinx">Ƿidsiþ 19:25, 8 June 2010 (UTC)
 * Delete and a tip of the hat to BD2412. DCDuring TALK 23:19, 8 June 2010 (UTC)
 * Thanks. Maybe I should stick to legal definitions. Cheers! bd2412 T 23:23, 8 June 2010 (UTC)


 * Maybe I am confused, but I think BD's statement supports keeping. It seems that unleaded fuel: always means "gasoline with less than .05 grams of lead per gallon" which makes it a set phrase with a meaning independent of its constituent parts, no?  I would not refer to propane or butane as unleaded fuel: even if they were free from lead, and if I asked for unleaded fuel: I would want gasoline 100% of the time.  While it may not be defined legally I don't see how it is SoP unless it can be applied to any arbitrary fuel or unless fuel is defined as a synonym for gasoline (which would be an interesting debate on its own). -  18:51, 11 June 2010 (UTC)
 * I think it's the case that, in the context of fuel unleaded: always means petrol/gasoline whether or not the word "fuel" is actually explicitly used. Actually, I can't off the top of my head think of a use of unleaded other than in relation to fuel - "lead free" is what I think of in other contexts (e.g. paint). Note that the antonym leaded: is used in a much wider range of contexts (glass, pencils, paint, etc). Actually, looking at the first 50 hits on google books for unleaded gives 59 books where the context is clearly fuel (I couldn't work out the context of the only other hit, and there wasn't a preview of it). Searching for unleaded -"unleaded fuel" -"unleaded gasoline" -"unleaded petrol" gave 1 hit related to glass, 2 with the meaning "non-alcoholic", 1 that I think had the meaning "decaffeinated" and 1 related to ceramics or paints for ceramics (I'm not certain which). Of the remainder all were related to fuels, with about half using other explicit formulations (e.g. "unleaded regular gasoline"). Thryduulf (talk) 21:44, 11 June 2010 (UTC)
 * This is sort of like decaffeinated, isn't it? We would not have an entry for decaffeinated coffee, even though it is likely that the vast majority of uses of the word refer to coffee. Also, the statutory definition to which I referred does not expressly define the phrase, "unleaded fuel"; rather, it defines "Motor vehicle gasoline, unleaded", and I included it here because it is the only federal statutory definition of "unleaded". Of course, there might be something in state statutes, which I have not looked at. bd2412 T 03:32, 13 June 2010 (UTC)
 * The decaffeinated coffee analogy seems like a good one. Thryduulf (talk) 08:09, 13 June 2010 (UTC)


 * I agree, the term decaf: is analogous to unleaded fuel:. If someone walks into a restaurant (in New England anyway) and says "I would like a cup of decaf" they mean specifically that they want decaffeinated coffee.  I suspect that in the U.K. the same term would mean a cup of decaffeinated tea.   We actually don't have those definitions at decaf right now.  If the term under discussion were unleaded gas or unleaded gasoline then I think they would be clearly SoP.  I think that the usage of fuel makes it less clear, or not clear at all, to someone unfamiliar with the term.  Now that we have a definition for "unleaded" which covers the term "unleaded fuel" the argument is more sound, although then we also need the noun form of unleaded as well. -  14:39, 13 June 2010 (UTC)
 * Nope, in the UK "decaf" means decaffeinated coffee. I don't like any hot drinks myself, so I don't go looking for it, but decaffeinated tea is not something that I would expect to find on very many menus at all (not that decaf coffee is ubiquitous either). Thryduulf (talk) 14:56, 13 June 2010 (UTC)
 * I agree that this usage calls for a noun sense of "unleaded" (as in, "fill 'er up with unleaded"), but an entry for unleaded fuel would then more clearly be SOP. bd2412 T 14:43, 13 June 2010 (UTC)
 * yes, a noun sense meaning "unleaded petrol|gasoline" is definitely warranted. Thryduulf (talk) 14:56, 13 June 2010 (UTC)
