quote:Huh? Does each state set different standards for this kind of thing? Where I used to farm (Washington State and Arizona) the off-road diesel has been low-sulfur for years. It's the same thing as on-road, it just gets dyed so that when the DOT sticks the tanks on the trucks and pickups they can issue a $10,000 ticket. In fact, the dye is normally (always?) added either when the shuttle tanker truck is loading up to deliver to the farm or even by that truck driver when he delivers at the farm tank. There shouldn't be any performance issues because the sulfur helped lubricate the fuel pumps. That lubricant had to be replaced with other stuff when the sulfur levels went down, so if anything the fuel should now be even more lubricious (sp?).

random sampling of motor oil and at times in the past there were numerous cases of samples being found that had low additive content.

This can be due to several factors. Of course one thing is that it may simply become hard to find enough chemical additives. But in addition as the price of motor oil, gasoline, etc. climb, there may be pressure to try to sell at a lower price by cutting back on quality.
