Eldergays, tell us about leaded vs unleaded gas

Leaded gas was used for cars built before 1975. I was born in 1979 and I remember my grandma's car used leaded gas.

In your neighbourhood maybe R1.

In the Castro in the '70s, 'leaded' meant a cut dick, 'unleaded' meant uncut.

In the '80s, well, lets just say, the focus was more on poz or neg.

Leaded gas prevented that annoying engine knocking.

Engine knocking?

Again, in the Castro, circa 1970s, the 'engine knocking' was slang for a prolapsed anus.

There were many.

Also leaded gas (which was called "regular") was cheaper.

[quote] Engine knocking?

In spark ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.

You know if this was happening now MAGATs would be arming themselves to defend their right to drink leaded petrol.

“petrol”, R8?

What country are your MAGATs in?

Or do you just watch them on the Telly?

R9, R8 here. I'll get back to you in a jiff about all that, but right now I've just got to go and answer a call on my mobile!

Jesus R8, do you shoehorn MAGA references into every thread?

I don't actually, R11. It just made me think of the meltdowns going on over the past couple of weeks about the government allegedly 'coming for' people's gas stoves.

Is that OK with you? Do I need to run all my posts past you for pre-approval?

Leaded gas smelled really intoxicating. At first, unleaded smelled like rotten eggs 🤮

R12 " It just made me think of the meltdowns going on over the past couple of weeks about the government allegedly 'coming for' people's gas stoves."

Over the past couple of weeks, the US government is Democratic. So MAGA isn't relevant to what you've just said.

Yes, the MAGAs are wailing that the DEMOCRATIC government are coming for their gas stoves.

You appear to have severe reading comprehension issues. I'd stop embarrassing yourself now if I were you.

R13 - I totally agree that the smell of leaded gas was intoxicating. I enjoyed being able to pump my own gas just to get to smell it.

Stealth poppers incoming at R16

Only MAGAs R15?

I liked the smell of gas and the smell of rubber in a tyre store,

Puny cocklet story incoming at R19?!

R19, bad weekend to say "tyre".

So what stops engine knocking now?

Actually, as I recall, you could not put regular (leaded) gas in a car designed for unleaded. The nozzles were designed not to fit. The knocking was connected to octane - higher octane was marketed as preventing knocking. As my childhood memories recall at least.

Leaded gas became illegal in 1996 and lead is related to learning and behavioral problems in children. Maybe that's why there are so many stupid people.

Isn't that diesel with the bigger nozzle, R23?

What about ETHYL?

Ethyl as in Mertz? Fred's wife!

We can't. The leaded gas retarded us.

So if they got rid of leaded gas then what helps engine knocking now? Cars still have spark plugs, right?

Unleaded refers to impotency in a man.

[R15] Look into new building ordinances in NY, CA. They are banning gas stoves in many areas for new construction. It is the democratic run states doing it. Get your facts together.

r29, higher compression ratios, and higher octane gasoline, in addition to computerized ignition retardation, prevents knocking in new car engines now... ultra-precise computer control of retarding ignition is kind of a new thing and was pretty much completely absent in the market when leaded gas was phased out...

[quote]higher compression ratios,

Mmmm. I like the sound of that.

@r22, "So what stops engine knocking now? "

They installed doorbells 🙄

Well I'm not a mechanic so I don't know, R34.

Tetraethyl lead was used as an additive to increase octane. That is why the lower octane gasoline was called regular and premium gasoline was called ethyl. Tetraethyl lead has been rebased with the cancer causing chemicals ,benzene, toluene, ethylbenzene and xylene. Since these chemicals can be deadly, our cars must be fitted with catalytic converters. You can take this info to the bank, the info above is gibberish.

As someone who live in a country that didn’t switch until the 90s I can’t really say there was a difference.

Wasn’t

in the above post I misspelled replace with rebased

leaded gas was sold in the US until 1996 along with unleaded.

^ How did they get the rotten egg smell out of unleaded gas? The stuff wreaked in the beginning 🤢

These threads, ugh...

PS. R41 It's the sulphur in the petrol that you can smell with unleaded if the catalytic convertor is cold (or old and fucked), once it warms up it oxidises the sulphur (hydrogen sulphide) into sulphur dioxide which is odourless. No catalytic convertors used with leaded, it destroys them.

Beavis and Butthead liked this sign they saw at a gas station:

"We pump ethyl."

^ Ok, thanks. You really know your gas 😉

It was called super in Australia. My vintage V8 ran on it.
