#2 Diesel fuel, used in warmer climates in the U.S., had a higher
sulphur content (It doesn't anymore, pollution, you know) and some
engines used the greater viscosity that they brought about to
lubricate parts of teh fuel system (Injector pumps, usually).

Nice cut and paste Pete, but there is more to #2 diesel than what you write.
California made #2 diesel madatory, so that the injector clearances can be
tightened. More recently, California has required additives to #2 diesel
that cause the engine's seals to disintegrate. This change has managed to
run this County's long haul trucking businesses to Oklahoma and other
operators to evade California road taxes by filling up before entering the
State.
