Re: What happens if you put petrol in a diesel car?

An owner of an original Ford GT40 , (it was either John Bonham or Tiff Needell i cant recall) filled his road-going car with diesel when inebriated .

Re: What happens if you put petrol in a diesel car?

uh-oh. Just read the RACQ site :_|


 


If you’ve put petrol in a vehicle fitted with a Common Rail diesel injection system, don’t even turn the key, as the electric fuel pump will circulate the petrol through the whole system, necessitating a major repair.


The extent of the work required to rectify petrol in a diesel vehicle will depend on the type of vehicle and how long it has operated on the wrong fuel.


In the worst case, expect a bill for several thousand dollars (repair costs of in excess of $10,000 are common), as rectification could require repair or replacement of much of the fuel system, as well as repairs to the engine itself if it has suffered damage


 


in other words, what Hawk said. :_|

thanks Hawk  NOT X-(


 


just did some googling and the tank capacity is 76 litres, so the mix ratio is less than 5 %.


More googling suggests that it will be ok.


I hope ol' mate keeps the tank close to full like I suggested.


 


I only picked the car up from the panel beaters on thursday from a slight altercation I had with a power pole and steel cable. $ grands worth of repairs. The boss is never going to let me drive it again.


Assuming it makes it back from where ever it has gone Smiley Indifferent



 


you never said how much petrol you put in, one can only think you topped it up with petrol which wont end well,


 


 perhaps providing all relevant info will return better info

apparently diesel in petrol isn't nearly as catastrophic as petrol in diesel.


 


The older type diesels can tolerate a bit of petrol but not the common rail type.


 


I've heard truckies tell stories of putting a gallon of petrol in their fuel tanks to make the truck go a bit faster. Apparently it would cause flames to shoot out the exhaust stacks Smiley Surprised:^O

Sorry Hawk, I did sort of (see posts 17 & 19 ) but wasn't very clear.


The tank was about 1/4 full, I put in 2.89 litres of petrol then added 40 something litres of diesel.


 


Anyway it would seem I have done a bad, bad thing and the vehicle will be rodent droppings.

a small amount of petrol (less that 5%) is some times added to increase performance, any more will put the engine at risk of serious damage.


 


I doubt it would be recommended for the more modern high performance diesels that rev to much higher RPM

Its only a very small amount so you may get away with it, you could drain half the tank or more out out and top up with diesel to halve the amount and them use what you have taken out in small quantities over the next few refills

My only concern would be that you have 3 lts of petrol sitting at the top of the tank until you let the tank get to nearly empty and it may then use the petrol. But colic sounds like he would know if it should be drained or not.

Petrol and diesel are both hydrocarbon based and will mix instantly.


 


pimpy I dont know how reliable this info is but it sounds reasonable that adding oil to make up for the lack of lube from the petrol is good.  read this artical http://wiki.answers.com/Q/What_do_you_do_if_you_have_accidentally_put_petrol_in_diesel_car

Pimps (pimp my ride lol), why not suggest to the owner (boss) to get the tank emptied, refill it with the proper fuel, and just hope for the best?

Hi Joz, i should have drained it straight away Smiley Indifferent


Someone has taken the vehicle away, i suspect to sydney so it will probably do a thousand K before it gets back (if it's still running) I just hope he keeps the thing as full as possible

Sorry for your predicament, Pimpy.


 


And is it a bad thing if I just heard Marvin the Martian say "there will be an earth shattering ka-boom"?

X fingers they didnt take it for a long trip Pimps


 


back in the early days when unleaded was introduced, motorist would fill their cars with it by mistake instead of super and if the valve stem seals in the heads werent designed to take it. it done lots of damage. It depended on the make of car.


 


lets hope this small percentage fuel you put in didnt hurt it.. as it might depend on the model diesel engine (goes back to read colics posts)

its a 2008 hilux 2wd. common rail which is the important bit.


I don't know whether to swear or cry or both :-(


I rang the boss earlier today to see if the vehicle was still operational. He hasn't heard anything to the contrary and was remarkably calm considering we (I) could be looking at 10 grands worth of damage. I've suggested he trade it in if it makes it back alive.


 


Hawks link was scary. it said the pump will break down and put bits of metal through the fuel system and stuff the injectors. Oh Joy Smiley Indifferent

perhaps in the event of this kind of damage his company vehicles are covered by his motor vehicles insurance policies? i so, i wouldnt sweat it.
