    Unhappy diesel in a petrol engine car

    Hey everyone

    My name is Dale and I work for my own production company. Recently I made the mistake of putting petrol into my diesel freelander which was very stupid at the time but after a lot of research found that it is quite a common mistake.
    Anyway my car instantly, and I regret this now, went back to the landrover dealership that I purchased it from. Upon arrival they didnt hesitate to qoute me just under 5000 for the repair bill and a void in my warrantly if I did not let them do this.

    Basically I had my car taken away and cleaned for 120 pound and its running absolutly fine. What I need is anyone who has done this in the past that wouldnt mind telling me about it. Also any mechanics that have any knowledge of this thatwouldnt mind being interviewed.

    I am putting together a short documentary as it seems to me there is quite a price for someone who didnt know too much about the damage which seems to me a lot of money is falsly being made.

    We are located in Kent so please anyone that could help me please contact me via this website or email me at dale@creativeecco.co.uk.

    Any knowledge that you have to share would be more than useful whether its negative or possitive.

    Thanks guys

    Dale

    its a very common mistake and your not the first , i used to just take drain downs to a local garage and forget about any problems , but i did a training course on diesels with the rac and seen damaged parts that would make your hair fall out .... it really depends on the car . if your car is running fine then don't worry to much , but please remember that if its a modern diesel then the fuel also acts as a lubricant . petrol is a spirit and will not lubricate but brake down the lubricant that the diesel provides . monitor how your car runs and go from there , but if you get any problems it will end up costing you .

    sorry i cant give you any more advise but its a hit and miss subject

    @ Eccodale

    Having worked in Land Rover Dealer-What you have been told is correct.Land Rover stipulate that if petrol has been added in a diesel and the engine has been run for more than two minutes then the complete fuel system must be replaced- fuel tank/fuel lines/injectors/fuel pump etc.......

    The reason for this is diesel fuel contains a lubricant that lubricates the high perssure pump in the system.What the petrol does is dry out that pump and as the tolerances are so small in the high pressure pump what will happen eventually is that it will seize and cause further damage especially if driven by a timing chain as most modern diesels are.

    As haggis says while on training I also saw the damage that can be done to the high pressure pump and its not pretty.So what Land Rover say is that if you want to keep the warranty on your fuel system and any linked components then you must have this work carried out after all it is unfair that they should have to warrant a system that has been compromised.

    What you should have been told is that its your choice if you only wanted a drain then you could have had that BUT a fax would have been sent to Land Rover Technical with your vin/reg number saying that the vehicle has had Petrol in Diesel.What this means is that when the vehicle details are checked every time the vehicle goes in for service/repair it will flag that to any dealer in the country.

    Sorry for the long post.

    Default pricing

    understanding the fact that the car may have faults in the long run and maybe having the work done by landrover itself is a good idea, the one thing that I cannot come to terms with is the price that it will cost.

    Now honestly can the quote of 5000 anyway compare to the price of a brand new engine itself, obviously minus all the compentaents that will be included for no reason, and personnally how much of this is the labour charge?

    It just seems that by taking away your warranty on the car, you have no choice but to pay them all the cash and I've also heard that maybe they dont actually replace all the parts?

    Obviously I'm not digging for any reasons to attack the garage, I really would like to create an understanding for other people as it seems that no one seems to care about the little people anymore?

    Cheers Guys

    I can't remember what the labour times are.Ask the dealer for a breakdown of costs i.e Labour/Parts/VAT,From memory the biggest chunk is labour but I may be wrong.

    As I said above the whole warranty is not void just your fuel system and related parts i.e if the high pressure pump is driven by the timing chain and the pump seizes this will cause further damage to the engine-The only time I'm aware parts are not changed(except for the fuel filter) is when a drain down is done

    No problem,unfortunately with the modern common rail diesels fuel contamination is bad news and I read once that it happens about 400 times on average per day nationally.

    Default wrong fuel

    we do fuel draindown onside of road andin our garage we carry a sealed tank that works on air we have to pay 35 p a litre to dispose of fuel we charge 100 call out most cars 1 hour labour 38.00 plus 35p alitre to dispose of fuel i have not found a car that you cant drain down on side of road as yet so there is no need for recover charges just charge them for what fuel you put back in

    I made this mistake on my 52 Golf TDI about 2 months ago. I realised my mistake having put about 20 petrol in an empty tank.

    I pushed my car away from the pumps and did not start it, i did however turn the ignition on.

    I called my breakdown and got the tank drained for 160.

    I had no problems for a month. However recently the car seems to cut out when slowing down and changing down gears. The car doesnt start up after it happens, and the engine ticks over before eventually starting after a minute or 2. It runs fine the rest of the time.

    Its happened about 6 or 7 times and usually when the tank is under a quarter full. I've taken it to 2 different specialist VW garages and had a full service and they havn't been able to identify the problem.

    Has anyone had this problem and do you think its related to the misfuelling?

    Any ideas would be appreciated!

    Am I missing something? The thread title refers to diesel in a petrol car, yet the content refers to petrol in a diesel. As far as diesel in a petrol, if anyone I know does it, we tow the car to my lock-up, drain out the contaminated fuel, and split it between a group of us. When diluted down it burns with a little white smoke, and does no harm when used in lawnmowers, go karts, generators and the like. It is also OK to burn it in older cars with no cats. Not only saving the cost of a drain, but gives a reserve for those who can use it. I think it is too expensive a commodity to 'throw away'.

    You are insane!!
    Doing a fuel drain an a lock up !!
    Dangerous and silly!

    Most cars will NOT like petrol contaminated with diesel old or not!....Its not worth the small saving you would make
