Basics

Diesel Fuel that has a Dye Added to show that it is not being used for “Road Use” and thus not taxed
Can be cheaper, although especially if filling Safety Cans etc it may not be worth the risk of someone accidentally filling up a Vehicle, then if you get pulled over etc being fines etc
It USED TO contain higher amounts of Sulfur (in the days before ULSD vs now where even Bunker Fuel / Sixth Oil has reduced/no Sulfur)
- Luckily this is no longer an issue (at least in the USA/EU, add checking other areas’ standards to the to-do list)

Potential Impact of Dye on Combustion

To Do:
- Look up what dye is used
- Depending on that try and do the stoic + see combustion products
- Also any deposits after Accelerated Aging Tests / other concerns?
