It will cause a lot of damage. AdBlue is for exhausts not engines.
not much, it just makes it harder to start when the engine is warm. but diesel in a petrol car...do not start or it wil destroy it
yes fill tank almost to top then add i gallon of petrol
Drain the tank, change fuel filter, add correct fuel.
Burn up the injection pump if too much was added. Itll stumble a little at low rpms. Add a tiny bit of regular motoroil in fuel tank to lubricate injection pump and run a lot of diesel through it.
The most effective way is to drain the fuel tank completely and then refill it with diesel fuel, add a bottle of methelated spirits to the fuel tank to ensure the water is no longer there, the metho breaks down the water particles and allows them to be burnt with the diesel, also change your fuel filter, as it can hold water, also the tank can become rusted /corroded due to the water being inside,
cheap gasoline,try a higher octane gas or add an octane booster to your tank
Their car either wont start or will shut off the the diesel gets to the engine. no damage. they'll just have to drain all the diesel out. If you're talking about putting, say, 1 gal of diesel into a gasoline tank that has 5 gals or more of gasoline the performance of the engine will be reduced. If this was the case (mistakenly put a small amount of diesel in a gasoline vehicle) I've simply fill the gas tank with gasoline and had no other problems; I was a gasoline retailer for many years so I'm talking many dozens of mistaken 'self-serves' that were non-events. Of course, if the gas tank that diesel was installed was near empty and someone put 5 gals of diesel into that tank it is best to drain that diesel before refilling with the proper fuel. Hope this helps. AND I would like to add this does NOT have any validity if one has put 1 gallon of gasoline in a DIESEL vehicle...If you added gasoline I strongly suggest you drain ALL of that mix out of that DIESEL powered vehicle immediately. DO NOT THINK of starting it.
It depends how much petrol was put in. If it was a "full tank" draining the tank and the system would be advisable. If it was just a small amount, the mixture can be cut by adding more diesel with some motor oil mixed into it It is a common practice in times of diesel shortages to use motor oil with a small amount of gasoline added to it in place of diesel. You will have to use your own judgment as to how much diesel and/or oil to add.
You have to replace your fuel filter, water separator drain your tank and add fresh fuel. Sugar placed in the fuel tank will not harm your engine. Most fuel filters will have an absolute rating of 5 microns (give or take) and granulated sugar has a various micron size of between 20 and 150 microns. either way, it's to large to pass through your filter.
Low octane fuel. Run a tank of premium through it or add a bottle of octane boost and it will be fine for a while.
If you have a diesel powered engine then nothing much would happen, the car would run a little richer than it should but will pass when you fill up again. If you car is NOT diesel then you may have an issue. I suggest flushing out your gas tank right away. It may not harm it right away, but if you continue to add diesel it will definitely harm your engine. But like i said, a diesel engine can handle normal fuel mixed in, it is actually advised to do so in cold weather so it makes it easier to start the car.
