    some sulfur acts like the lead in leaded gasoline. but not nesisary.
    the first diesel engine didn’t use diesel fuel it was peanut oil. so straight vegie oil will work.

    In the long term, there may be some bad effects from the low sulfur. Sulfur helps to give diesel fuel its lubricity. a diesel relies on its fuel to lubricate the internals of the fuel pump and injectors, so they may wear out somewhat faster. I’m sure the fuel companies will compensate with additives in the fuel, but i think its like lead, there just isn’t an equal.
    The positives far outweigh any negatives. This is what was holding back the flow of euro-diesel cars from entering the US. Hopefully the American companies will follow suit( and hopefully they’ve come up with some better diesels since the early 80’s!).
    I wonder if big brother is going to make the truck guys strap cats on older vehicles. The fuel itself won’t make you lose too much power, but newer trucks will have a bunch of new emissions control devices and that may strangle off a few horses.
