I didn't know Mexican crude can do Jesus' multiplication of bread miracle, lol.

Or is the final process of putting water additives?

I'm a bit confused here. Did you not state you use off-highway diesel? Not being familiar with US law is not off-highway diesel ULSD? Or do some states allow special higher sulfur diesel for farming and generators and such?

My car vehemently dislikes Mexican refined gasoline*. When offered an alternative I use the alternative which includes PEMEX PREMIUM which is good fuel and 101% of it is USA refined. At home there are no alternatives. Here near the border, ARCO, and BP stations abound. They use only imported fuel minus the alcohol. When I went to the cardiologist last Thursday the stations in Chula Vista California were selling fuel for around $3.90 gallon. With alcohol. One ARCO station has a sign advertising "E-15 $2.75 gallon" I refueled in Mexico.

I would LOVE to see refineries build gigantic Alkylation plants and use the isobutane that is damned near given away for free. Requiring all gasoline to contain a minimum of 20% alkylate would radically improve gasoline and minimize emissions. Of course there is no alkylate lobby in Washington DC.

MoPar with Mitsubishi 3.0 engines. Mitsubishi and MoPar forums have I'll bet a thousand threads about how sensitive these engines are to gasoline quality.

A performance/dyno tuning shop owner in the city down the road 3 hours was on a radio talk program about gasoline. He had a customer bring in a Corvette. Dyno power down below spec. Pumped discount seller “premium” out of the tank. Put in some V-Power. Dyno output returned to Chevrolet spec. The customer had his removed gas tested to find out it was 87 regular. But it was cheaper....

This whole discussion is pointless.

There are only something like a dozen refineries in the whole US, maybe fewer.

Unless you live within 100 miles or so of a "brand name" refinery, the gas you get comes out the end of a pipeline and goes into a holding tank......from which trucks with ALL of the brands present locally fill up. ALL OF THEM; same gas.

Now they claim that the driver or the tank farm operator puts in a package of brand name specific additives when the tank truck is filled. There is evidence that doesn't always happen.

Do whatever makes you feel good......for whatever reason.....and don't worry about it.

All garbage today and Pemex is even more garbage.

One of the big differences beweeen Branded and unbranded gasoline is quality control. I'm not so sure there is that big a difference at the refinery but for example.. Michigan has a law that says for a specific size tank you can only have so much water in the bottom of the tank..

Standard Oil. back in its day. had a standard for water in teh tank too. 1/2 of the Michigan standard. If you have 51% of what MI allows. they sent a truck and pumped you out. fixed it and billed you.

A friend of mine laughed at me for paying for Standard.. Till I had to tow his ride to the shop so the mechanic could put in a new in-tank fuel pump. the water froze and broke it.

Shell, with platformate ;)

I'll save you the trouble:
