So last night i filled up with fuel at the servo... i did think it smelt a bit like unleaded at the time but did not think much beyond that, I get half a kilometer down the road and car stops... after much cranking it re starts and goes another couple hundred meters and this process happens about 4 times when i decided that i must have put unleaded fuel in the car.... i get out and take fuel cap off and sure smells like unleaded

Long story short i go back to servo and find out that unleaded fuel is coming out from the diesel bowser... yep i know absolutely unbelievable but this Mobil outfit had some how managed to do it

I already have drained the fuel and purged diesel thru and have the car running but even though i drove only a short distance i am very concerned if there could be even minor damage caused... there was very little diesel in the fuel tank when i put it in so it would be a very strong unleaded mixture that went thru the engine... Im thinking about hitting Mobil up for a new injector pump and injectors... and if they want to play games ill put the car into rane rover and have them swap these components out and give Mobil the bill, I guess what i want to know is there anyone who has done this or experts who understand the fuel pump and injectors on these well enough to know if there will already be damaged caused to these tight tolerance components which are normally lubricated by the diesel fuel

Im really angry... well im just worried that if i don't take action now in 6 months time ill have to replace the fuel pump etc at my own cost which would be rather dear

Very bad for a common rail diesel engine.

As above - it's extremely likely that at the very least the Diesel Fuel Injection Pump will be severely damaged - they rely on the diesel as a lubricant.

A distant acquaintance did exactly the same with a new RR Sport last year, the engine and pump were severely damaged = £4K bill at the mainagent 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

My good lady wife once managed to fill one of our diesel vans with petrol one time , I drained the tank and filled with diesel and the van was 100% no issues whatsoever BUT that was our fault and not a great expense if it died 3 month down the line.
Not your fault so screw mobil for as much as you can at the advice of a nain dealer as to what needs doing
Good luck

I used to work as a contractor for a couple of landrover dealers years back when the TDV6 / TDV8 's first came out.

Misfueling was quite a common issue back then and a lot of owners had to make insurance claims for the repair as the dealers used to replace the tank, all fuel pumps and injectors. Not sure if this was 100% nessasary but I was told it was.

I'd be getting it booked in somewhere asap. Can't believe they had unleaded coming out of the diesel pump!

Big oops on the part of the fuel station! I'd imagine that they'd be liable for the damage, too - they certainly would be in the UK; surely Ox will be similar ...

Get it recovered to a reputable garage and obtain a report. Regards,

You didn't drive very far so Imo drain the tank, change the filters, and all should be fine.

I filled up my diesel estate with unleaded a few years back.
The AA here in the UK will do a drain for members. They used the cars own pump to empty the tank, replaced the fuel filter, and put some injector cleaner / lubricator in the tank. I think it was made by millers. I did a further 100k miles in that car without it missing a beat.

I do recall a friend doing the same on his BMW and the garage replacing the tank, pumps, filters and injectors.
This seems overkill to me and think it's just the dealer pulling your pants down.
Once it's all flushed I can see no reason why any further damage will result. Too many toys, not enough time

Given the circumstances, I'd find a local main dealer and have them quote.

I'd agree that if it were my fault, picking up the wrong filler, then I'd drain it & hope for the best, but this case is a bit different.

In the worst case.....I hope you have written to them with registered post or similar.... you don’t want them to forget in 6 months time.
If u have a legal insurance with your car u may want to consider asking them. I don’t think that counts against claims... again worth checking before jumping.


I suspect you will need a prompt report, rather than a problem later on ,that you then try to pin on them... what a
b r

In the best case there is no problem, but I’m not capable of technical comment one way or the other. Filters are in fact so good that in certain circumstances, when the ambient air is already polluted, a diesel car will tend to extract more particles from the air than it emits. Emissions Analytics worked with........etc etc

He who dies with the most toys wins...

I used to work for a Jaguar Main Dealer. When they first launched the 2.7 V6 TD in the S-Type and X350 we had no end of owners put Super Unleaded in thier new beast purely out of habit. Regrettably as other have said, I can confirm the high pressure pump uses the Diesel as a lubricant and consequently starting it with the wrong fuel just leads to the death or serious injury of the pump and (because of metal fragments breaking away from the now non-lubricated pump) the injectors too. If the owner realised thier mistake and didn't turn the key in the ignition and prime the pump, we could drain and flush the low pressure side of the system. If it made it into the High Pressure side, we replaced the components and the owner would usually have a bit of an argument with the Insurance Company and ultimately get paid out.

Personally I would be on the phone to them, irrespective of symptoms (or lack thereof) which you have now rather than wait for the damage to rear it's head in a more catastrophic and expensive way.

I'm sure this is obvious, but the very first thing to do is get the till receipt for the fuel. If you haven't got one, the garage might be able to provide a copy.

I had a query with Shell some years ago after my and some friends all had problems after refuelling (with the correct fuel) at the same station. They needed the pump ID from the receipt. They later rang me and said the fuel in that pump had been checked and was fine. I seem to remember asking for the report in writing, but was told they didn't usually do this.

Funnily enough, the station closed a few weeks later and they dug up and replaced all the underground tanks.

I didn't pursue it further because on limping to my garage for repair, a different fault was found. Old 110 2.3 Petrol ???? - ????
