nothing the 2stroke-petrol will smoke as it burns the oil which should be mixed in it
It will overheat the engine
What happens is you must remove the petrol immediately. Petrol or gasoline will destroy a diesel engine.
The engine will overheat & seize due to lack of oil. A 2 stroke needs a fuel oil mix to lubricate it's moving parts.
If you put petrol in a diesel vehicle do not start the engine. Petrol will do serious damage to a diesel engine. You must drain all the petrol out and flush the fuel lines.
Ordinary 87 gasoline, the same you put in a car. It depends if it is a four stroke or two stroke engine. If the engine has a separate filler for oil then plain petrol will do. If there is no separate filler the 25 to 1 petrol /oil mix should be OK.
you dont mix water with oil. If you have a two stroke engine it needs oil and petrol in the tank or it will just die on you. But if you have a 4 stroke you just put petrol in the tank. Hope this helps.
It will dirty the injectors a bit and run very rough,if at all. Still, not as bad as putting petrol into a diesel engine .
If you put gasoline/petrol in the oil resivoir of any engine, you will destroy the engine if you do not drain the oil and add fresh oil immediately. Start running that engine and it will not last long.
Well the first necessary piece of information I would need to know is: Is it a two stroke or four stroke engine? I assume its four stroke as I'm sure you know that you need to mix two stroke oil with petrol and then put it in the tank if it's a two stroke. In that case, 25 to 30ml of two stroke oil to a litre of petrol is perfect. On the otherhand, if it is a four stroke, 300-400 ml of oil should be about right.
Who told you it is harmful? It is only harmful if it is a Diesel engine. If it is a petrol (gasoline) engine then Petrol is what it takes to run.
It won't run. Diesel is ignited by compressing the vaporized fuel much higher than a gasoline (petrol) engine. A SMALL amount will result in very poor performance.
I would recommend not running the engine until the fuel is drained. Any amount of petrol/gasoline in a diesel can cause engine or fuel system damage.
