Although it is technically possible to turn red diesel into white diesel, mainly through various bleaching processes, it is almost impossible to totally remove the chemical signature of the red dye from the diesel, and even trace amounts can be detected.
- Differences Between Red and White Diesel
The main difference between the two types of diesel lies in the dye. Red diesel does not carry fuel duty, which is the reason for the very strict rules
where it can be used.
It also appears to be of a lower grade, as many who have used it in cars or trucks admit that the vehicles in question do not seem to run as well, and the red diesel also seems to involve greater output of soot and smoke.
- Cost Involved in Bleaching
To turn red into white diesel generally involves investing in a variety of chemicals and equipment. By the time all this has been paid for, it is more cost-effective to just buy white diesel in the first place.
Turning red diesel into white is illegal and, if you are caught, carries large fines. In addition, the car it was used in often gets impounded for at least 12 days. It will then also cost to have it released again.
As a whole, everyone across a whole range of sources seems to agree that turning red diesel into white diesel is simply not worth the effort. There are only very few people who are willing to take the legal risk involved.
Considering the expenses, time and effort as well, especially as traces of the dye's signature will remain and be detectable anyway, the whole idea of trying to save money by flaunting the law and tampering with fuel seems to be a pretty pointless exercise.
