And don’t forget “green” diesel that is f-ing up marine diesels... another enviro navy project. Nothing like a career REMF “leader” to suck up and ruin the point of the spear in our fighting forces on the front line, now with the chinee— who are NOT concerned about ...the “environment”. Sheesh, and thanks.
I believe you.
I used to spot-heat with kerosene 10-15 years ago. Then they introduced low-sulfur kerosene & diesel - basically, the low-sulfur kerosene causes the cotton space heater wicks to attract moisture and clog up quickly, necessitating a replacement, while your space heater stutters and fumes until you replace it @ $15 a pop.
Had to quit using it.
Eventually, I ran across a document showing that one of the low-sulfur ingredients is "bio-diesel", at a required 7% of the mix.
"Bio-diesel" - french fry oil, animal oils, etc., etc. If the 7% varies higher, not only do you have the bio-cr@p in your fuel, it's doing other stuff to your machinery, in your case.
