Update regarding Diesel Fuel In Mexico
Owners of late model diesel powered powered vehicles coming in to Mexico need to be aware of the following: 1. Ultra Low Sulfur Diesel fuel (ULSD) is still not widely available in Mexico, and SOME...

I've had a question about this since 2007 and posted it many times on this forum without answer - ignored I guess.
When you put 500ppm into a system designed only for 15ppm are there long term implications? In other words - is the life of any component in the system shortened meaning shortened life expectancy and need for parts replacement? And how much might any repairs cost at some point down the road?
My understanding - and I know nothing and don't pretend to know anything - is that engine manufacturers could not get emissions down nor could they design a system to cut emissions until refiners were able to get sulfur down to 15ppm - the engineers could not come up with a system that would effectively remove sulfur emissions from the engine. So the refiners got ppm down and now the system works. So if the engineers could not get a system to work why would we now expect that the system works when sulfur is higher than 15ppm? And would we not expect some long term adverse results from using to improper fuel in a system designed for fuel with some 30 times less sulfur?
I have no answer. Have never heard an answer.
We do know - at least based on news reports - that Mexico now imports hundreds of thousands of barrels of US fuel per day. So it is possible at least some fuel in Mexico is low ppm. US does not produce any significant quantities of higher ppm so we expect all export is ULSD - as far as I know the old LSD is only used in some ocean going ships. So chances are ULSD can be found in Mexico though there is no way to know if that is what you might be getting.
