Running a 2.2 tdci engine on unleaded - likely damage?
A guy who works with me put £30 of unleaded in his missus's Jaguar X type Se (same 2.2 tdci engine as the Mondeo ST Tdci) and drove it 10 miles before it made a horrible racket and conked out!
I reckon its probably knackered the pump, but his son whos a mechanic said it'll be fine once the tank/fuel lines are drained??
Anyone on here had similar experiences and what was the outcome?

Very likely to be totally fucked.
Happened to a chap on a forum I used to go on, the petrol destroyed the pump within 3 miles, sending shards of metal down the fuel lines, through the injectors and into the engine.
Luckily for him it was a brand new car, and it was the dealership that filled it with unleaded, apparantely the bill to put it right was into the thousands of pounds....

I think its a lot more serious than he does at the moment - apparently the tank was almost empty of diesel when he put the unleaded in (he always runs them almost dry before filling up LOL), so it would have been running on pretty much neat unleaded.
Im amazed it got 10 miles TBH.

The problem with the more modern stuff is it tends to swell seals and jam things in the pump, no metal would have got down to the injectors, I would drain all then try a start on diesel all you can do, but if it's someone else's fault leave it to them.
Older diesels would be no problem, just refill with diesel and off you go again.
It is possible to completely wreck engines though, luck of the draw a lot of time.

He's got an local garage out to recover the car today and have a look at it. I'll let you know how bad it gets!

as alex has said, it's going to be costly as you need to replace everything in the fuel system because it's been contaminated
so you start with the fuel tank, work your way along the fuel lines, filters, pimp, injectors, etc
our drivers have done it a few times, when we've had the bill back from ford/mercedes, it is always in the region of £3-4k
swap the filters, oil, blow through the lines with air to clean them up, flush everything through with clean diesel, then part chop it in for another jag

We might be doing things wrong at our ford dealership i work at but all we do is drain the tank, blow out the lines new fuel filter, £15 worth of diesel and they start and run fine. Even a smax that was driven until it stopped re-started and was ok afterwards.

Ah ... I've put Petrol in diesel tanks before to stop fuel gelling if the heater was on the fritz ..
£30 as a % of capasity is a little extreme .. You might be ok .. Might be ££££ worth of head ache ..

Too many posts.. I need a life!!
I have done a few Audi/VW's that have had petrol and they generally are fine if you get it flushed well.
However, we had a guy with a Touareg R50 with only 6000km's on it, he completely fucked his. Was filling up from a tank of diesel he had on his farm, done 10 tanks and on the 11th he got the dregs at the bottom, had diesel bug in it and water. Car was running rough and cutting out, we told him not to drive it and get it recovered and he took it on a 300km road trip.... 10 new injectors, 2 new fuel pumps etc etc, ended up costing the guy around $25k NZD.
Car is now for sale through us at $150,000NZD he paid $195,000 just 8 months ago, so he lost $70k in 8 months.....

one of our vans filled up from empty at heathrow, went all the way to margate, then concked out on the M25 at junction 10, so well over 200 miles on purely petrol
another one had about a tenner of petrol on it, diluted with the rest of the tank worth of diesel that we drained and went into ford about 3 months later with the pump fucked
we've paid for 3 fixes so far though and they've always been north of £3k so perhaps your examples are just filled up and not run?

Dojj - in general its not mate - your experience is spot on.
Its the clearance in the pump that are the issue - the diesel acts as the lubricant, petrol however does not!

I work for a mercedes dealer and we have vans and trucks come in which have ran on diesel till it stopped we just drain the tank fill with diesel plus a new filter then run it up every vehicle has always ran fine after, and i have seen probably 15+ in 3 years.
Besides its his cheapest option at the minute so worth a shot regardless

the pump clearances are set so fine now a days that they will fook up with the petrol going through, thats not to say they will straight away but they will sooner or later and its more likely to be sooner.

I agree with this lad put new diesel in plus a filter and run the car you will find it will probably be ok.

Worked for arnold clark ford and had one. Mondeo 2.0 tdci which had petrol put in, no one owned up so the car was started and used until it stopped working. Tried draining, cleaning, refilling. No use.
In the end needed new injectors at a dealer cost of £2500!!!
I hope for his sake a drain and refill works, if not get it traded in!
Just don't come to me or any traders on here or he'll get a kick in the sacks!!
Good luck, let us know the outcome

None never get any problems at our dealer and if it went else where we would here about it because we was last to work on it. never change anything more than the filter and put fresh diesel back in, infact i know of a vehicle that has ran on petrol and is still going now with no problems i personally dont think you will get many problems from a common rail pump

Update time
The car is now running, they eventually got it started by some means (probably easy start ) but its running none the less.
All they did was drain / flush the tank and lines and put £20 of derv in it.
Took them nearly a day of faffing about to get it going mind you.
Time will tell to see if it lasts or not?
Cheers for the tips/advice etc guys!
