Adding sugar doesn’t do anything beyond possibly blocking up the fuel filter. It won’t dissolve in gasoline, so it’s no more effective than sand. Water in quantity (1L or more) works great because it won’t dissolve in gasoline and is denser, so it’ll sink to the bottom of the tank and get sucked up by the fuel pump.
if you can get into fuel tank you can do so many more interesting things. chlorinated solvents will burn giving hydrogen chloride, and this will corrode everything downstream, pretty fast at that because it’s hot
also if you can fuck with fuel tank, you might be able to do the same with engine oil. fine alumina or silica added to it will cause quick weardown of moving parts that at the same time looks natural
not sure what kind of (permanent) damage water will do to engine, maybe it’ll look like it’s flooded if enough gets in
AFAIK, the whole point of adding sugar and sand to a gas tank is that they clog up the filters, and that can result in the in the engine stalling… after an indeterminate amount of time.
The idea being if you can add enough, stealthily, now the car fails without an immediately apparent time-proximal cause.
Do that to an entire motor pool, or a good chunk of it, and you can functionally force a decision between a significant amount of logistics and repair costs, and fleet downtime… or, deal with a random number of vehicles failing randomly.
Sand is… probably better at clogging up fuel pump filters faster than sugar, and if any actually gets into the actual engine, can cause more damage there.
Water, on the other hand, is more likely to rapidly cause an ICE vehicle to either sputter or stall… but you have to use a good bit more water than sand or sugar.
Pouring a good amount of sugar into an ICE vehicle’s gas tank will also … uh… give that car a … tummy ache.
EDIT: Water is more effective, and sand even more so.

Anyway, back to my jam.
