Diesel fuel (known as gas oil in some countries) falls into the same general range of petroleum distillates as No. 2 fuel oil, which is commonly used as a heating fuel for buildings or as 'red diesel' fuel for off-road agricultural vehicles, emergency generators, etc.
In the US, diesel intended for on-road or commercial vehicle use (which is not dyed, and is sometimes called white diesel) has to be refined to a lower sulfur content, whereas No. 2 oil or red diesel does not have to be refined as much. No. 2 oil or red diesel are thus cheaper to produce but more deleterious to air quality and machinery, since the sulfur content of the fuel oil reacts with moisture to form sulfuric acid.
Since these three products are functionally interchangeable, and since the taxes on road diesel are also higher than on red diesel or No. 2 oil, government regulations in most countries require that off-road diesel be dyed so that inspectors, vendors, and purchasers can distinguish between the various products.
Illegal use of off-road diesel or No. 2 oil as fuel for on-road trucks or construction equipment is still a common practice.
It is a tax issue. Dyed diesel fuel is not taxed, and as long as the fuel is used on the farm it can be run in anything, but when dyed fuel is used on a road vehicle you are cheating your state and town of tax revenue needed to maintain roadways.
if it is dyed diesel then no it is agents the law
In the USA, highway fuel varies from clear to yellow. Off road fuel is dyed red.
Some diesel fuel is only supposed to be used by farmers. It is cheaper. The dye is there so it can be found if used in improper vehicles. The fuel is the same, just dyed. It will not hurt to use it.
Since 2007 most diesel pumped at any station in the USA or Canada is ULSD, regardless if it's on-road (clear) diesel, or off-road (dyed) diesel. The only difference is the fuel is that by using it as off road the taxes are not the same and it is cheaper. Dyed diesel will not affect your engine.
They can use either on-road diesel (billed out as reefer fuel, as its use is non-taxable) or red dyed off-road diesel.
No. Since a school bus travels "over the road" it is subject to the fuel tax, unlike agricultural fuel, for example, which is dyed red and tax free. If dyed fuel is found in an over-the-road vehicle, the owner/operator can be subject to fines of up to $10,000 in the USA.
Diesel is two different colors that include light yellow and blue. They are different colors so that people can distinguish between the two in order to know what is best for their vehicle. Light yellow is for vehicles that run on the highway while light blue is for marine and agriculture vehicles.

Some tax-free fuel supplied to farmers is dyed because they are not allowed to use it on the road.
