Unleaded petrol mixed with Diesel in a Chrysler 2.5CRD
Hi My dizzy wife just put 11 litres of unleaded PETROL (gasoline to our Cousins in the US) in her DIESEL Chrysler 2.5CRD (2003 model) There was probably about a quarter tank of Diesel in it before she refuelled so 11 litres of unleaded petrol went on top of that, THEN she realised her error and put 40 Litres of DIESEL in on top of it ! Result, probably about a mixture of 5 parts Diesel 1 part Petrol !!! One Guy in the Garage said she must NOT move the car as it would damage the engine and needed to be drained out completely etc etc etc Then an RAC man on a bike ( who was refuelling himself ) said that most Diesels will run just fine with a little bit of Unleaded mixed in, he went on to say that my missus could run it on sunflower oil or chip pan fat too ? The garages are shut for the weekend of course and she already drove it home about 3 miles without noticing a difference Who is right, The RAC man or the Garage attendant ? Has she ruined it already? Thanks in advance |

The RAC man. > Has she ruined it already? No. My advice would be to just keep using it, and frequently top up with diesel to reduce the petrol ratio. Mike. |

If this is a common rail diesesl (hence CRD?) then you may very well be stuffed. The lack of lubrication from petrol can very quickly kill the high pressure pump. > Who is right, The RAC man or the Garage attendant ? Both, yet neither. > Has she ruined it already? Potentially. Just keep topping it up with the right stuff, and if you've not buggered it yet, you probably won't. If you want to be certain, get the tank drained before starting it again. Your call. A new pump could cost thousands. |

When I used to drive to Russia, we used to mix petrol (or paraffin, depending what we could get) in with the diesel in winter to prevent it from waxing and in approximately the same ratio too. I also know someone who did the same thing in a Land Rover recently and it just smoked for a while until all purged. Personally I would imagine it will be fine. -- Regards, Vince www.TruckDrivingInRussia.co.uk |

If that's the case, then let me ask the obvious stupid question: If it's a matter of lack of lubrication, is there some oil that could be added right away on a one-time basis to make up for the lowered lubrication to save that pump (of course without causing other problems)? It sounds like in reality from other posts that it should be OK anyway, but I was just wondering about mitigating the possibilities for damage.

Absolutely not. We have bulletins from the manufacturers now (in my case Honda) that suggest even priming the fuel system can cause damage to the fuel system on the latest high pressure common rail diesels. If it hasn't been run, then DO NOT START IT. You can then get away with a simple drain off clean out an refill. If it has been started, then your troubles begin. You have two choices, carry on and take a chance, or replace every component on the fuel system. The common rail systems run at very high pressure - somewhere up to 2000 BAR is normal (yes, that's over 20,000 psi). The pumps reply on the diesel fuel to lubricate it. One or two sources I found using Google suggest that the material of the bearings is damaged by petrol. If the pump is driven by the engine, and you opt for option 1, then there is a chance that the pump can sieze later on. If this happens, then it'll cause drive damage to the drive system of the engine, and possibly the head too. I'd expect this to cost up to £10k. The manufacturers are recommending that we change all the components of the fuel system, and flush the lines and tank (On BMWs you have to replace the tank too) - this includes the pump, injectors, filters and high pressure pipes. Costs for this start at about £3k. If you take it to a dealer and get them to flush the tank it might only cost a couple of hundred pounds. It depends on how much you want to gamble really. -- Andy Hewitt ** FAF#1, (Ex-OSOS#5) - FJ1200 ABS Windows free zone (Mac G5 Dual Processor) <http://andyhewitt.webhop.net/> (updated Nov. 2005) |
