I noted that those in Northern Ireland will now not be allowed to use Red Diesel. This is something to do with something called Brexit that has now passed me [and the news] by due to something called COVID. When I fill with red diesel I always pay the full VAT and keep the receipt. I also try to use white diesel when I can, by filling in France [when allowed to go] or delightfully, cheaply, in Guernsey [when allowed to go].
I have heard of boats having a hard time abroad [when allowed to go] when found with red diesel. I know my tank will be contaminated by the die used. However, I'll be trying to fill with white diesel using cans. I wonder how long the die will remain in my tank.
I make this post part as advice and in part looking for comments as to the approach by others.
I use only clear diesel, cost isn't an issue as I rarely use more than 40 litres a year, I was told by yanmar its best thing for there engines, also I am told the dye lasts over 20 years
