Its the lack of lubrication that will damage the engine. Was it a her or a you?

BTW about 5% petrol is generally considered safe.

Did you start it?
My mother in law did the same a couple of years back with her skoda. She only realised when it conked out. Local garage sorted it out and it's still running now.

I used to think my vegetable oil with petrol. *Diesels are pretty versatile 😀

Edit: Old diesels.

I'd drain that out if I could, old diesels might cope but not many are that old.

I think petrol in diesel is not quite the disaster that it is the other way around.

Depending on the engine - less than 10% in the tank i'd fill up with diesel and run it through.

Sounds like you have more like 25%, in which case i'd try and siphon.

Nope. All that happens with diesel in petrol is that the engine won't start (or the plugs might need cleaning). Petrol in diesel will do permanent damage.

I've got a small pump for oil/diesel in the shed and you are quite near me, any use?

I put £18-worth of diesel in a petrol Astra GTC! In mitigation, the filler flap had a label on saying diesel quite clearly.

I brimmed it and drove it a couple of miles into work. Currently parked there awaiting my return later this evening.

It's the Mrs Urban Cruiser 😳

According to honest john if you fill with diesel and keep tank brimmed the petrol stays at the top of the tank and very slowly mixes with the diesel over time so it doesn't damage the engine. Don't let the tank drop below 2/3rds.

Closure.

I called Fuel Fixers and had a guy turn up last night after work. He drained the tank, put in 10l of diesel, started up the car and left it ticking over to check it was OK. His analysis was that as I'd already had 1/3 tank of diesel before travelling the 2 miles to work then nothing else would be affected.

I got home ok.

£300.

I retrospect it would have been safer to leave the car on the forecourt but I had to get to work to take some cyclists back to Fort William and there was no other way.

sweepy- thanks for the offer. Not sure what I'd have done with the 45l of contaminated fuel though 🙂

Check your insurance. This is quite often covered with no excess or effect on no claims.

^^ really ?

Glad the engine is ok OP, in 7 years I owned both a diesel and a petrol car I was terrified of making this mistake.

dad did this to our fiat. i put some two stroke oil in - to aid lubrication and no problems since:)
car wasn't worth hassle of draining and the like.

Much harder to put diesel in a petrol, the nozzle doesn't fit. The diesel nozzle is bigger than the petrol one

You would have thought there would be a fail safe they could build in - you shove the nozzle down the hole and it 'sniffs' the contents to see if it's giving off petrol or diesel fumes before it starts to flow. Or use different coloured plastic liners on the pipe to the tank and if it senses the wrong colour it won't start.

Leaving the OP out of this I tend to take the view if you can't put the right fuel in a vehicle then you probably aren't the right frame of mind to be guiding 2 tonnes of metal at 70mph.

even so you would think that one nozzle could be round and one could be oval...

Or a big yellow sticker with DIESEL written on it above the filler or something?

Hang on a minute...

It's not like there's a shortage of them on this forum 😆
Regarding petrol in a diesel,one of my mechanic mates told me that one of the issue's is diesel lubes the seals on the fuel pump,whereas petrol doesn't & the pump fails.

[quote="convert"]You would have thought there would be a fail safe they could build in - you shove the nozzle down the hole and it snaps shut and stops you from filling the car. Called a misfuel device.

Fitted to thousands of cars as an OE thing these days.
My car has one.

Still doesn't stop some idiots physically hammering the wrong nozzle past the device to fill with the wrong fuel.

Much like those we get putting diesel in a petrol. By using good aim and spraying diesel down the side of their car (or physically hammering the wrong nozzle into the filler head.)

Doesn't work so well in countries where they play fast and loose with what nozzle they actually put on the gun though. Or some of the low cost chains who also don't really care.

Ford already have this tech. The unleaded filler is too small to fit a diesel nozzle (like most petrol vehicles nowadays I'd have thought) and diesels have an O-ring which has to be forced open to release a locking flap which the petrol nozzle is too small to expand.

According to "the man" diesel in a petrol car is much more common than you'd think possible in a country where things are designed to protect against it.

He also reckoned that many hire companies are removing any Petrol/Diesel stickers from the filler area. I can't see what advantage they gain by this but he's seen it a lot.

Why so? It's a lovely week car. Ideal for our use and leagues above the 4x4 Panda we also looked at.

Did 15L in a near empty 70L tank. Brimmed it mmediately, and kept it full for a few weeks, no harm done. Redex is just petrol AFAIK .. just not bought in 15L quantities 😀
