G’day Tyler
The bloke I talked to also mentioned volatility.
The fuel we had “jellify” looked very similar to what your images show. The first time it happened was on a frosty winter morning and had a bit of comedic value.
The family went out in the car which started and managed to get a kilometre or so down the road and then failed to proceed. Following a phone call I went out in the Landcruiser, to rescue them which got a little further and then similarly conked out. I walked back and we got the smaller tractor out which didn’t even make it to the gate onto the main road.
Three vehicles, all stranded. I went back inside and had cuppa, one of those days.
