Mexican Gasoline

[gn7]

My guess is pemex may have a higher sulfur count and less detergents in it.

My guess is it is not what they putting in, but what they aren't removing, and what the actual chemistry is in their blend.
Gasoline isn't just one compound, its dozens. The gasoline in the US, and particularly Cal and NY, and some other major cities in the country is a completely different formulation than other parts. But all gas in the US is what they call "reformulated gasoline". If you sold this stuff in 60s and 70s, you would go to jail because it doesn't come near the definition of gasoline as described by the feds back then.

When cat converters first arrived, the smell from cars was disgusting. When the sulfer in the fuel hits the converter, along with any unburnt hydrocarbons, the heat in the convertor makes it form hydrogen sulfide. Rotten eggs.

My guess is that Premex doesn't go thru the process to eliminate the sulfer in the fuel and that's what you are smelling.

Way above my pay grade buddy. Lol. I just put the shit in my car. Lol

If you drove a car in the mid 70s when converters first came out, you'd know that smell very well.
But like I said, its not what they are putting in, its what they aren't removing.
You hang around a refinery and you see tanker trucks hauling molten sulfer out about once an hour. Don't ask where they are taking it, I have no clue. I just know between the diesel and the gasoline, they are removing one shit load of sulfer every day.

There is a place down in the LA ports that sells sulfur in powder form...yellow shit stank to high hell...they did nothing to even try to cover it....it smells like rotten eggs, and worse....

A lot of that is headed over seas for steel production. Huge piles of coke from the refineries down there for the same reason. But it doesn't smell.

I dont know if it is still the case but I recall hearing that there WERE over 40 formulas in the U.S.... Nearly every state had their own formula and by law could not use supplies from other states that dont meet the spec...

I dont know if it got WORSE or better since the time I heard that statistic..

All Missouri gas is 10% alcohol minimum... Plus who knows what else...

There is a formula for every climate, and elevation in the country, and it changes with the seasons. It is not unlawful for some states to share gasoline. It is unlawful for all of calif and much of NY and some other densely populated areas from using gasoline from other regions.
This enumerable variations is gasoline thru out the country is very reason why I am so anti E85 for use in the GNs. It is IMPOSSIBLE to baseline. It simply cannot be done. They use a water gauge to determine the alcohol content, but NOBODY can tell what alcohol, ethanol or methanol. It is also impossible short of a laboratory to determine the gasoline used in the E85. Anybody buying E 85 for a GN at a station is a fool, and there aren't many fools in the GN class. So who are they kidding. Get rid of the mixture and just change the damn class to K V bottom and knock the bullshit off.

The purity of gasoline today verses even 25 years ago cannot be compared. The gasoline today is more synthesized than refined. Its distilled, cat cracked, hydro cracked, isomerized, alkylized, demerized, and cat reformed. Basically, it totally dismantled, and reassembled into what they want it to be. No different than synthetic oil.
There is nothing in that fuel they don't want in it. Its great for emissions, and shit for mileage and power.

How does the gas from other states effect a car? Say for example I take a cross country road trip and my car requires 91 octane and as you explained each state has their own "version" of gasoline. Is the difference enough to adversely effect the car?

Note to self: Never ask GN7 what time it is unless you want a 20 minute dissertation on the differentiation between what we call the time of day and the relative variation to the world atomic clock

Only kidding dude.....no offense meant

[ChumpChange]

Most land locked GM motors have that same smell

The Fords are broken down so no fumes are released.
