Colorless (?) #2 Diesel Fuel

[LBrown59]

<font color="blue"> Road diesel aka low sulfur has up to 50 parts per million sulfur content. This gives the varying shades we see at the pump.
On the other hand, off road diesel has up to 500 parts per million of sulfur. If you look at undyed high sulfur diesel it is dark yellow almost orange compared to low sulfur diesel. You will also notice a distinct sulfurous smell as opposed to a "lighter, cleaner" (for lack of better description) smell of the low sulfur diesel.

2 things bug me about the above statement.

I just don't see the object of making one diesel fuel with 2 different sulfur contents

Why do we need more sulfur in the diesel fuel to dye it red so we can deduct the high way use taxes on it?

I didn't even know they make high sulfur fuel anymore?

Like I said earlier.
There's no point in making one diesel fuel with 2 different sulfur levels.

<font color="blue"> My dad use to drive a fuel tanker the 2 were the same as far as I know about 2 yrs ago. The total volume wasn't enough to warrant carrying 2 blends of fuels
1*they simply added dye a cheap solution.

<font color="blue"> I don't get how road diesel is worse than off road as truckers do not want to wreck their engines.

Truckers don't have a choice what they buy. It is regulated by the EPA who has no concern or not if it is better for your engine.
