Out of gas

selamun aleykum
While talking among friends recently, the gasoline was over, after that you started the engine a few times, and being unable to start the car would cause problems in the barrier (I don't remember exactly where he said)
1) Does the man who runs out of gas and can't start and run on the road damages his car?
2) In case of running out of gas, how many lt should we buy? (For vehicle with LPG)
Pleasant forums

I don't think there will be a problem, it is diesel, not air.
Let the tank always be 1/4

As it says in gasoline, it does not air like diesel vehicles, fill the tank as much as a quarter of the tank or a little less.
