Petrol In A Diesel Engine Car

[aerolet]

Yesterday I've put 5 liters petrol in my Toyota Auris D4-D 1.4 by mistake, what should I do, shall I fill the full tank or shall I empty the tank? Thank you.

Firstly, a long shot. I'm sure I've seen some insurance company advertising a policy that covered you for just such a scenario, as you are not alone in having this happen. Maybe worth checking insurance policy? (although I'm wary of actually speaking with them, other than at renewal time!)

I keep my cars a long time, so in the interest of preserving the engine as much as possible, I'd drain as much petrol out of the tank (and fuel lines) as possible, as the modern high pressure diesel injection systems don't like ingesting petrol with it's lower "lubricity".

How much diesel was in the tank before you added the 5 litres petrol. And did you run the engine after you realised your mistake? Have you enough containers if you did decide to drain off the tank's contents?

Sure others will be along with more advice - hope it's not caused you too much anguish.

I know a guy in the pub who knows everything and he told me no worries if you put some petrol in a diesel car up to a point.

Let’s say you put about 5 litres of petrol into a 55 litre tank, then he says if you add about 4 or 5 shots of Redex or the equivalent quantity of 2 stroke oil to the tank and fill the rest up with diesel then you’re likely to get away with it.

That man Sir knows burger all ;)

Whilst 5 litres is not a lot, petrol in modern high pressure diesel pumps is not good. The fine tolerances can cause massive damage to the pump if petrol is run through it. In the bad old days we used to put petrol in diesels to stop it waxing in the winter but you cannot do that these days. It should be pumped out of the tank without running the car, and if any of the fuel pipes / unions are opened, they should be replaced as they are use once items. If you have run the car, you should remove the pump for specialist cleaning

Like I say it is not a lot and you might get away with it, but we do not have the full facts to make a judgement

Nah, he says he knows what he's talking about and explained it all to me for a couple of piints of lager. He says the octane rating of petrol is about 95 while diesel is about 25 so the oil will reduce the octane rating. On lubricity he says they had to change the material they made the high pressure gear pumps out of to a tougher spec when they introduced low sulphur diesel. He says you don't even need to change the fuel filter provided it's reasonably clean before the mis-fuelling took place. He says the modern fuel injectors - even though they operate at about 1,000 to 3,000 bars are ok with the mix, it's the swarf contamination that might have come from the gear pump if Redex hadn't been added that tends to jam up the spray holes.He also says that the sensors won't get covered in soot since the combustion process won't be significantly affected.

Mind you he also says he reclaims used brake fluid by filtering it through a nylon stocking and then heating it in an open pan to evaporate off any moisture it has absorbed.

Oh well this bloke is from the pub so he must be right.......crack on then........ :lol:

If it's only five litres petrol you put in then if you just fill the tank with diesel it should be ok
