I am still searching for the clip of the epic sludge in some batches of fuel. it was in a live stream of the “Inside Russia” Youtube Channel, and he posts very long and exhaustive videos, so it might take me a bit to find the source i was talking about, but these clips (especially the one from the guy who used a nylon stocking to filter the fuel) are a good basis, although what that guy had in his filter was childs play to some batches i have seen which were sold on the black market.
Edit: still searching, but to recreate the needed mental image, the crap in the black market stuff is somewhat like jello with strings in it. Even if your fuel filter is capable pf dealing with the more solid stuff, the amorph crap in there will probably make it beyond that barrier and will fuck up everything regarding fuel injection that is the default nowadays.
I do not doubt you one little bit, but do you have a source on the russian distillates being downgrade? Because if you do, I can cite it.
