They won’t if they used water to dilute it. The gas station probably banks on the cars being able to leave the area after refueling. They will run off the old fuel at the bottom of the tank and in the fuel lines for a bit.
I would personally hazard a guess at diesel. It does have such a low octane number that octane isn’t really a relevant factor for it, it won’t immediately destroy an engine, and Russia’s oil & gas industry will already be making it in large quantities and probably even transporting it to the same places as the petrol
Sorry, to clarify: my guess is that the petrol is being diluted with diesel. That would work better than most other adulterants, and it would also explain a drop in measured octane. I dd specifically mean octane; you can measure diesel’s octane and it is very low, it’s just not relevant in normal usage because diesel engines ignite their fuel differently to petrol ones
Depends on how much water. A small amount of water and the engine will run better when warm, this has been known for years. (in 1915 some engines came with the factory with a separate carburetor just for adding water) It doesn’t work if there is any ethanol in the fuel though, so almost nobody does it. The biggest downside is it needs a warm engine, if the engine is not warm it just runs bad, and in the worst cases it won’t even start.
You’re talking about water injection, which is very, very different from having water in your fuel lines, which will make the car not run at all. Water has a higher specific density than gasoline, and will settle to the bottom of the tank, which is where the fuel pump pickups are located. And an internal combustion engine cannot combust water because it’s… water.
Water and gasoline do mix just fine in small amounts. When the car is moving it shakes enough to mix a little more. This is small amounts though, they may be mixing more water than that.
Other reports suggest this isn’t a case of mixing water, but instead a low grade gasoline that shouldn’t be used in engines because of ocatane.
My personal guess elsewhere in this thread was diesel, since it does have an extremely low octane number compared to gasoline and it would be easy for Russia’s infrastructure to supply

They most likely use ethanol to dilute it.
Engines will run just fine on it for years (until they don’t), and Russia has more than enough of it.
I like the idea of Russian gas stations deliberately taking the lead in disabling Russian automobiles
Water separates from gasoline, and sinks to the bottom.

Diesel is rated by cetane, not octane, and the cetane numbers are lower. There’s nowhere that diesel would have a cetane pump rating of 92.
That’s certainly gasoline.

Ohhhhhhhh yeah that makes sense!

Wouldn’t water increase octane rating, since higher octane fuel is harder to ignite wth compression and water wouldn’t ignite at all?
I don’t know what that tool measures but I wouldn’t be surprised if it didn’t account for water correctly.
Though since then I’ve read reports that this is not water but just bad gasoline.
