Default NW Pajero wrong fuel

The Missus has put unleaded in the NW Pajero instead of diesel and then driven about 70 km's, telling me the car is running funny when she arrived home!
The Paj was fuelled up on Saturday night and she only put 22litres of unleaded in it, as we were meant to be going away in the Patrol for the week and she only put in enough fuel to do what she needed. This meant it was probably about a 70/30 Unleaded/Diesel Mix, so hopefully still had some lubricating properties.

After she arrived home, I looked at the Paj and at first thought it must have been sucking in air, as I'd done a service the week before and changed the fuel filter. But it soon became evident that unleaded was in the mix as we could smell it, so we checked her fuel receipt and yep, wrong fuel!

I was stressing all night and thinking the worst, failed injector pump, injectors etc, and I couldn't find anything in my insurance (RAC WA) PDS relating to misfueling. The RAC Insurance call centre had closed for the night, so I waited until they re-opened at 8:30am today and gave them a call. A big sigh of relief, they told me it was covered as it is considered accidental damage. The next step is to get it towed to a workshop and get a repair quote back to RAC, I've delayed my trip by a couple of days to hopefully get the Pajero into a workshop and get things moving along.

So we've dodged a bullet there and a potential $10k claim will now only be a $500 insurance excess. (Along with the resulting increase in next years premiums no doubt) I discussed this with forum member sharkcaver and we agreed that there is a good possibility that there may be no damage to the injector pump etc due to the ratio of diesel in the mix and it may all be good. So I've tossed up just draining the tank and changing the fuel filter etc and seeing how it goes, but I think I'm far better off heading down the insurance path, in case there is an unforeseen problem with the pump or injectors etc.

I'll let you all know what the damage is once they give me a quote.

Sorry to read of your mis-fortune. Hopefully it's not too bad & the insurance delivers. The RAA is SA also covers accidental mis-fueling, but not fuel contamination (which irks me, as I consider that to also be accidental damage, which is what insurance is for).

Might be worth considering a "diesel fuse" insert/cap for it, if you are no longer filling it from cans, truck pumps, etc.? I think the risk of mis-fueling increase dramatically when you have both petrol & diesel cars in the family.

Best of luck.

Bugger!

Unfortunately easy to do, and I guess you were lucky it made it home under it's own steam, and your Mrs was aware enough to detect that something wasn't right.

70/30 petrol/diesel isn't as bad as it could've been, but still not a nice prospect. I think you're on the right track - get your insurance company involved ASAP, in case it all goes pear-shaped.

In the bush, I'd try flushing with fresh diesel and hope for the best getting to help. But that's not your situation, and I don't see any up-side to taking unnecessary risks.

Good luck.

Yep, the diesel cap thing will definitley be looked at, she was tired and not paying attention and unfortunately this is the result. The insurance rep I spoke to reckons its pretty common for them to have this occur. Something that could have been easily avoided if they used fool proof nozzles/tank inlets to start with when designing diesel cars.

Yep, I agree, I've gone ahead and the claim is being processed, tow truck will pick her up tomorrow and I'll give MM a call and let them know the claim number etc. I'm now hoping they change the pump and injectors to avoid any future issues that may occur due to this.

Before the modern common rail diesels using the wrong fuel rarely caused any damage. Had my son fill my Landcruiser with petrol and it died 20km down the road. He dropped the fuel refilled it and carried on for an extended road trip. I then used the diesel/petrol mix in my ol series 2 Landrover for nearly 2 years. Never ran better!

Hope you get Pajero sorted with limited damage.

I did something similar about 5 years ago. Put about 20 litres of premium into a 60 litre diesel tank on a toyota hi ace. I realised my error after about 2 klms of driving. No difference in driving ..the penny just dropped that I,d stuffed up. Drove the 4klms to home extra slowly in higher gear and immediately put 2 litres of 2 stroke oil into the tank. That was about all it would take. Drove carefully for about 50klms and topped up with diesel. Carried on driving as normal. No problems at all. Good to hear about the insurance side of things. Hopefully all will be good. I have also fitted a bright yellow diesel cap on mine (naturally it sits under the fuel flap.

Mis fuelling was such a problem in the US that VW changed the fillers on all diesel models to prevent it happening. Standard on all diesels since.

Link to mis-fueling prevention device:

https://www.raa.com.au/shop/caravan-...cap-sd2-thread

Sprint Auto also list them.

Should be fine for "town cars" I would think.

However, I do have a few concerns about installing one of these on a "offroad car":
- will it allow dirt into the tank when inserting the filler, particularly after traveling off road when the filler area will be full of dust & dirt? Perhaps a dust cap will be needed to cover it?
- I have heard mention that it may foul the inside of the fliier flap when closing the flap?
- Truck pumps probably can't be used
- Filling from jerry cans may prove tricky, as the filler will need to be the same size as a servo diesel filler nozzle to open the solo cap

Has anyone fitted one of these or a similar product?

I looked at one of these quite some time ago and had the same concerns as you have listed above. I was mainly concerned about dust in offroad situations. The Pajero doesn't do any offroading anymore and is mainly used for carting the wifes market products around town. So I think I'll be having a close up look at one of these when we get her back on the road. My step daughter also drives a diesel Hyundai i30, so I might do the same for hers. I'll have to have a good look at the Pajero filler again, as it has the dual tank fillers, so I'm not sure this will fit.

Another option previously mentioned by others is big stickers, yellow paint, etc.
I reckon a big sticker like "Its a DIESEL you #*%#@!!!" might sell well?
