Wikipedia
An oil is any neutral, nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (immiscible with water, literally "water fearing") and lipophilic (miscible with other oils, literally "fat loving"). Oils have a high carbon and hydrogen content and are usually flammable and slippery.

Wikipedia
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas or atomic gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer. The interaction of gas particles in the presence of electric and gravitational fields are considered negligible as indicated by the constant velocity vectors in the image.

petrol, is a transparent, petroleum-derived liquid that is used primarily as a fuel in internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives.

Oh yay, we're going to turn this into another "which regional term is correct" discussion.

@Zenith talking about oil was a pretty obvious joke at the Wankel's thirst for it - and I've never met someone who confused gas for oil in their car as @CallmeDan seems to indicate - but regardless of whether they're popping the bonnet or the hood, it really doesn't matter.
 
If you use the term "gasoline" it is clear what you mean. If you say "gas" it is unclear what you are referring to, especially if the thing in question that you are referring to is not a gas. Is it natural gas, gasoline, trapped gas, hydrogen, air, carbon monoxide...

You get my point.

Was it really not clear from my post that I was referring to the oil burning tendencies of Wankels?
 
SUB-ZERO!
The crazy colours, spectacular sound, historic triumph and mighty engine are more than all the reasons I need.

In America, if you say anything other than gas in a normal conversation, people look at you like your avatar is looking at me.

Where I'm from, if you made a fuss about someone using the term "petrol" or couldn't fathom what they meant, then other people would give you a look like Roger's avatar. The united states covers over 3.5 million square miles. Not all of it is Indian Falls, NY.

I'm pretty sure Zenith's post can't be taken to mean Wankels use considerably more farts than a piston engine, so I don't really get your point when the original context was pretty clear.


Especially when he said the word "oil", not "gas".

Oh I agree, it works like that here as well depending on who you talk to. Car enthusiasts get it, average people look at you funny.

I don't think you do considering you just said in America, everyone says gas & give you a funny look if you say something else. Your region says gas, his region says petrol. It has nothing to do with car enthusiasts getting it.
 
I had my headphones on at 4% and I had to turn that down...

Wow. That was loud. Hasn't got anything on a Viper though.

From my experience of talking to Americans, if they are talking to a European and said European speaks in British English, they don't bat an eyelid. Same the other way round. If I'm talking to an American, I don't particularly notice or care when they speak in American English. I'm far more likely to notice if someone is speaking Scots or in a strong northern accent, to be honest.

Gas is an ambiguous term here because to most British English speakers saying that you run your car on gas will bring the assumption that you either run your car on natural gas or on LPG, and therefore gasoline or petrol is preferable terminology when crossing dialect barriers.

This is entirely true, at least typically.

Standing at the Esses at Le Mans last year, I heard the 787B start up in the pits. I didn't stop hearing it until well after the Forza Motorsport chicane. Well after. And that was on a parade exhibition lap.

The Vipers were quite loud within the bowl of the Esses itself - louder (if grimier) than the Corvettes and Ferrari 458s - but the 787B at dawdle made the flat-chat Vipers sound like a Renault Twizy.

Well that's not quite what I meant. People here say gas, but you're not guaranteed a funny look if you opt to say petrol instead, because not everyone in the entire united states lives in a fragile insular bubble where their mouth would hang agape just because you used one o' dem furrin' words.
 
I wasn't saying the Viper is louder, I was referring to the quality of the sound. The bassy crackle of those big engines has something almost musical about it.
 
The two at Le Mans sounded broken. Although they may well have been.

The 787B is just one of the aural wonders of the motoring world. At any revs. At idle it sounds like a lunatic trying to pitch sea anenomes to Mach.
 
The throaty warble of 10-cylinder engines probably lends more to the Viper's sound than its displacement (which is large, no matter how Slash wants to drag his hopelessly ethnocentric mindset into every subject). I wish I could have a chance to listen to a 787B in the flesh, but it seems like it has the impact of an alarm siren going all-out. My first impression of it was like a never-ending train whistle. And the way rotaries end up with a stumbling idle is interesting, as Eunos_Cosmo shared a while back:

It sounds like one fire then one misfire, but it's actually 3 misfires followed by 3 fires, per rotor, because of the three-sided rotor. From Mazda:

The sound the Viper puts out isn't all due to displacement, it's more so based on the number of cylinders, firing order, crankshaft style and camshaft profile.
