Petrol Mixed With Diesel

Answer 3

Petrol in a diesel car not to bad.. diesel in petrol car.. bad news.. my cousin put a £10 of diesel into a petrol van once and we had a right nightmare siphoning it all out and then tow starting the van doing about 40 mph not the best way to spend 2 hours on a early Monday morning.

Answer 5

you have two choices!
drain the tank of the contaminated fuel recommended but you won't do
or top up with diesel and take a chance of damage
the engine will run fine and probably not get damaged its self but the part that gets damaged is the injector pump
this is because of the very tight tolerences of the parts inside the pump which rely on the diesel for lubrication which the petrol reduces causing the parts in the pump to wear out prematurely
you can see if there has been damage by removing the fuel filter and in the bottom of the filter housing you will see tiny pieces of shiny metal that has come from inside the injector pump
thats the risk
the choice is yours!

Answer 6

No problem, just top up your tank with diesel and it might knock a little bit, but will return to normal as you keep topping up with diesel and the petrol becomes more diluted.

Add diesel to petrol in a petrol car - oh dear, that is trouble big time.

Answer 7

unlike the old straight simms type injector pumps fitted to cars of yesteryear, modern cars use rotary injection pumps - these rotary pumps use the diesel as their lubricant.

Petrol has very poor lubricating properties compared to diesel, so in brief, if you run the engine you wear out the injector pump.

If you have not run the engine with the petrol in u can just drain the tank, if the engine has been turned ALL the fuel lines will need flushing.

You can just about get away with 5% petrol - but 30% is pump suicide!

Answer 8

It all depends on how much you put in.If it wasn't very much, don't worry about it.If ,on the other hand you put 5 or more gallons in,then you really should drain the tank and refill it with diesel.It causes the engine to run hotter and if too much was added then it could damage the engine.When I was in the army we used to mix petrol and diesel so the trucks would run faster.But they were called multi fuel engines and were made for that.

Answer 9

Hmm a small amount is not going to do matter too much - although not advised, some lorry drivers add petrol to stop the diesel freezing in winter

We really need to know how much you put in - 10%, 50%, 5% ?

Answer 10

A lot depends on how much petrol was mixed with the diesel.diesel engines work by compressing the fuel oil, whilst petrol engines use the petrol vapour, too much petrol could seriously damage the engine, it will need to be cleaned out probably.

Answer 11

Depends on the car.

If it is an older car, with low-pressure indirect injection, you'll probably get away without any damage - just top it up again with diesel as soon as possible.

If it is a modern car with common-rail or pumpe-duse direct injection, you probably caused thousands of pounds worth of damage to the injectors and high-pressure pumps before you had even engaged first gear on the filling station forecourt, due to the lower lubricity of the fuel.
