Vapor Lock[edit]

The techniques and technologies described for preventing evaporative emissions and vapor lock in automobiles are terribly obsolete. The conversion to electronic fuel injection and pressurized fuel-rail delivery was largely complete more than 20 years ago and vehicles without fuel injection are now reasonably considered antique. The paragraph needs a total rewrite to be current. — Preceding unsigned comment added by Drcampbell (talkcontribs) 16:50, 2 October 2012


Hi. The following is contradictory and I have taken it out of the article until it can be clarified.

The first sentence says that autogas refers to gasoline, while the next sentence says it refers to LPG. Which is it?

"The terms "mogas", short for motor gasoline, or "autogas", short for automobile gasoline, are used to distinguish automobile fuel from aviation fuel, or "avgas".[1][2][3] When used with reference to cars, Autogas refers to LPG."

Stability and ethanol[edit]

The "Stability" section says: "Gasoline containing ethanol is especially subject to absorbing atmospheric moisture" but the Dry gas article says "The belief that dry gas is not needed because of the significant amount of ethanol is largely true because ethanol is a drying agent." Neither sentence is attributed, but I do not think both can be true. Thoughts? (talk)


"In many countries, gasoline has a colloquial name derived from that of the chemical benzene ... " Really? Benzene is THE PROPER name of the chemical. IE: it is the literal and most formal scientific name. Avoids all misunderstanding. Nothing 'colloquial' about it. As against all other meaningless and confusing misnomers used in the English speaking countries that ARE colloquial. The sentence should read something like: Many countries use the proper chemical name 'benzene' - spelt to the requirements of the language - ... — Preceding unsigned comment added by (talk) 08:18, 26 December 2017 (UTC)

Certainly "benzene" is the correct formal name of the chemical benzene, but it is not the correct formal name of gasoline, which is what the sentence is trying to express.
Maybe I see what you're driving at — are you trying to expand the sentence as gasoline has a colloquial name derived from the colloquial name of the chemical benzene? I suppose that's a possible reading, clearly not intended; maybe we could reword to avoid it. Suggestions? --Trovatore (talk) 17:42, 26 December 2017 (UTC)
