Communication with just text is a struggle. (Thanks for the laugh ! )
I'll try again: I don't think it's that bad here. I do think there was a problem this one time with the one station's gasoline (the one where I buy gasoline for the trimmer). I think our cars run better with a good fuel system cleaner, but you should add the cleaner more often here.
Good observation about tipping the taxis to get in a little more fuel - and a great example of how designing the best "fool-proof" systems only breeds better fools. (Not you - the taxi drivers and Pemex workers - *grin* )
Again, complete communication with just a few lines of text can be a struggle: Filling a vehicle past the pump's auto-shutoff does not harm the motor. It screws up the vapor collection emissions control systems (see diagram in the previous link). When you poison the vapor condenser canister ("charcoal canister") with liquid gasoline by overfilling the tank, the charcoal typically never works right again - and the car then leaks significant amounts of gasoline vapors for the rest of its life.
Since the raw gasoline vapors have substantial amount of benzene and other likely carcinogens, it's not nice having a car emitting hazardous vapors all the time (running or sitting). The raw gasoline vapors come from the sitting car then comes into our homes (in garages, carports etc) for our families or neighbors to breathe. The car also usually emits significantly more HC pollutants for the rest of its life, especially if the canister has been poisoned more than once.
So, the taxi motor runs fine, but that says nothing about the overall vehicle emissions.
