CeeJay Posted May 19, 2013 Share Posted May 19, 2013 Oh dear, oh dear, definitely having a senior moment as this morning decided to fill the car with diesel, however, for some reason my mind was on my petrol strimmer thinking I must get it serviced. The car already had just less than a quarter tank of diesel but I put in about 2 litres of petrol until I realised my mistake!!!! Continued to fill up with 40 litres of diesel on the premise that it would somehow weaken the petrol and mix it all up!!!Do I need to take any further action or will it somehow be alright weakened down?

Chancer Posted May 19, 2013 Share Posted May 19, 2013 What is the make model and year of your vehicle?If its an older generation one like mine then you definitely wont have any trouble, from what you had said I estimate you to have between 45 and 5O litres of carburant (assuming you brimmed it) of which 2 litres of petrol.A few years back I recovered about 40 litres of petrol with a bit of diesel in it from someone making the same mistake but who didnt react as quickly as you [;-)], tried it in a mower and it made too much smoke, tried it in my 2 stroke machinery and it didnt like it either so I resorted to doping the diesel in my car tank every time I filled the tank and remembered to leave space for it.So my vehicle (older generation diesel) ran happily for a few year with 4.5 litres of petrol in a similar sized tank, better than that it felt more responsive and the economy inproved, well it would when you think of it I was adding abou 10% of free carburant!!Unless someone more knowledgeable or a prophet of doom posts I think you can relax [:D] Link to comment Share on other sites More sharing options...
John Brown Posted May 19, 2013 Share Posted May 19, 2013 I agree with Chancer, if it knocks a bit keep topping up with diesel until its well and truely diluted awayThe other way round and it would have been very costly !Last person I know who filled up at the services on the way to the UK ended up paying out hundreds to get back on the roadThey got as far as the slip-road off the service area but had to be recovered etc Link to comment Share on other sites More sharing options...

Yonner Posted May 20, 2013 Share Posted May 20, 2013 I did similar- although with significantly more than 2 litresof Petrol!! - with a 2003 Audi someyears ago. Even though a modern engine,it coped after I brimmed the tank with diesel, the occasional sputter with thefirst tank, then fine. As Chancer says, you should be safe. As it happens, I recently put 45 litres of diesel into an all but empty 21 year old petrol golf.That took a lot more “ fixing.” Link to comment Share on other sites More sharing options...
ericd Posted May 20, 2013 Share Posted May 20, 2013 As explained above, no worries to be had. Fill tank to the brim with Diesel and you will be ok. Reverse operation or a lot more than a couple litres of petrol inside would have been costlier as you would have had to drain the tank. Link to comment Share on other sites More sharing options...
Clarkkent Posted May 20, 2013 Share Posted May 20, 2013 Doesn't it depend on whether or not the engine has conventional injectors or is common rail? A fuel injector engine will cope with mishaps like this but a common rail engine has electronically controlled injectors which operate at very high pressures and which are sensitive to factors such as viscosity. Perhaps someone with a more thorough understanding of Diesel engines can enlighten us. If the model has DCi or similar inits name then it will be a common rail vehicle.

PaulT Posted May 20, 2013 Share Posted May 20, 2013 It can harm the sales in the fuel system as they will be designed for diesel and not petrol - petrol can attack the seals. Link to comment Share on other sites More sharing options...
John Brown Posted May 20, 2013 Share Posted May 20, 2013 Obviously the safest way to deal with the problem and not risk damaging the engine is not to start the vehicle at the forecourt and have the vehicle transported into a workshop to have the tank drained and rinsed out but if the car's been started any potential damage to the seals and or injectors could have already happened anyway.Given in this case that it was a small amount of petrol diluted in a tank full of diesel IMO it's worth taking the chance for running it out of the system by keep topping up the tank diluting it even further. Injector require the lubricating properties of diesel so will fail if the mix was too strong.I'm sure we will have an update on this one from the OP Link to comment Share on other sites More sharing options...
Chancer Posted May 20, 2013 Share Posted May 20, 2013 I have heard a lot of these stories re common rail diesels, I think its probably true when the whole tank is filled with petrol and the engine run until it dies, however I think a lot of garages also make hay while the sun shines and replace every expensive component that they can as a precaution.I know that my mechanical injection diesel was missfuelled and then ran until it died, it was by my pal and the day I was due to buy the car, I must say that I was apprehensive about any possible pump damage but 100000 miles later and with the motor having done neaarly 300000 miles I would say that none was done.Injector seals and pump damage from petrol? I can certainly see the latter if run at 100% petrol but at about 4%?? Dont forget that diesel and petrol only differ in how high up the fractionating tower they are drawn off in the refinery.The fractionating tower bit was based on my technical college education over 30 years ago so I'm sure they dont do it in the same manner now before anyone corrects me!!!

ericd Posted May 21, 2013 Share Posted May 21, 2013 Right, I have just spoken to my friend Nigel who works at the local SAAB garage. He has been in the business for 20 years and I trust all is says as far as cars are concerned. If the volume of petrol is restricted to 2 litres, the OP should be ok assuming he fills his tank with pure Diesel and keeps toping it up with fresh Diesel at every opportunities. The petrol (Nigel says) will act similarly to an engine cleaning fluid that we normally add to the tune of 200ml to each tank full. Link to comment Share on other sites More sharing options...
John Brown Posted May 21, 2013 Share Posted May 21, 2013 Great, we nearly all agree that it should be safe to run the car until its consumed all the mixtureBTW Ericd I started as an apprentice vehicle fitter in 1965, you do the maths !Having said that, it was once said you can forty years of experience or you can have one year of experience for 40 yearsHope I was the former Link to comment Share on other sites More sharing options...

Chancer Posted May 22, 2013 Share Posted May 22, 2013 That was exactly my experience, given that I probably used up the diesely petrol over 20 or so fill ups I am convinced of it[;-)]I do however resist the temptation now of adding a little petrol from the same pump at the end of the fill up, people behind in the queue would get the hump and one day I would get the order wrong [:-))] Link to comment Share on other sites More sharing options...

Jonzjob Posted May 25, 2013 Share Posted May 25, 2013 My very first diesel was a Citroën BX Estate bought from Greenford Motors, W London and when I went to collect it they had very kindly given me a 1/2 tank of petrol. It had been fine when I test drove it, but when I drove it back to the office I was working in it was awful. I phoned them and took it back. It only just made it!When they realised their mastike they drained the tank and washed it all out, but afterwards it was total rubbish! It had the endeering habit of suddenly accelerating!! One time was on the dual carridgeway West on the Oxford bypass when I had just changed down to 2nd behing a line of braking traffic!!!!! The garage finished up getting a reconned engine fitted. That was a load of pony poo too and I got rid of it and bought a new BX TZD Turbo Estate. A fantastique motor car!! Link to comment Share on other sites More sharing options...

They have only a tenuous connection to the 'Powerdesal' moniker, that comes from the fact that my career subsequent to leaving the RAF was as a power and desalination engineer.
