(T) put unleaded in my GP diesel - long term probs?

i got a GP (06 model, 2nd hand) in which i put 3 litres of unleaded by mistake but then filled with diesel.

so i got a 45 litre tank with 3 litres of unleaded in it, goes just like it always did am I going to get long term probs?

i have almost done 100 miles will top up again today to dilute it down again. bloke at work says prob no damage as so little put in and some people do this deliberately to stop diesel waxing up in winter (sounds like old wives tale to me but whatever).

will my engine or any other part be affected long term - as i say can't tell the difference with normal driving although i am driving gently until i can further dilute it.

Comments or help grateful...

I wouldnt think it will be a problem as you have diluted it with a large amount of diesel!

hi i think you should have told the petrol station at the time because it happens all the time to them and they could have sorted it out. i personally wouldn't have topped it up with diesel lol. im not sure about if it causes much/any damage to the engine tho.

Don't mean to scare you, but I read somewhere if you put the wrong stuff in the car would cough/splutter and won't go much of a distance. If I was in your shoes I would let a garage take a good look at it..

as far as imaware a petrol station wudnt be able to sort it out? down where i work at sainsburys, the petrol station there just give a leaflet of a company that can drain the tank or summit, bit of a price to! as with the petrol goin in the diesal tank, u shud be cool, herd of it happenin loadsa times b4!

Its fine, put a fivers worth of petrol in a works van once and then realised what i had done. Went and spoke to an AA guy that was stopped at the petrol station and he said just fill it to the top with diesel itll be fine.. .

It smoked a bit for the rest of the tank but ran fine, i wouldnt worry.. .

The chief tech from the official dealership here adviced my to put 2-3 litres of unleaded in each fillup during the winter to avoid diesel freeze ( I have not followed his advice though ).

So, I guess you will be all right.

but i have already driven 100 miles now (feeling very sick and sweating buckets) but as i say it drives like it has always done. doing the maths 3 litres out of 45 is about 6% 'contamination' - and if i fill up later today with another 10 litres it will reduce it to below 5%. i can only hope no unseen internal damage has been done!

no smoke but i'm still worrying!!!

thanks all for your replies, i've been lurking for ages in this forum and knew where to go when i did this rather stupid thing. will get a big sticker for my fuel cap that says DIESEL

Unfortunately this is the bad way of doing it, diesel in a petrol is not as bad. As already mentioned in some countries they put 10% petrol in to prevent waxing so generally speaking as long as you put less than 10% in you should be fine. If you have been driving around with no problems then just cross your fingers mate.

you should be fine dont sweat it, my dad used to put a little petrol in his old diesel sierra in the winter years ago, and used to until a couple of years ago when we had works vans, high pressure injection is different now but thats not a large amount at all so other than a bit of extra smoke you will be fine.

You should be fine. A friend filled up his diesel entirely with petrol and didn't realise till it ground to a halt two miles later! the tank got drained and the pipes flushed but there was no long term damage as it went on to do another 50,000 miles with no probs.

As you only put in a small amount of petrol it should be fine. Keep diluting it with more diesel when you can is probably a good idea too.

As it is still going it's safe to say that you have got away with it! Bet you don't do it again

Well everyone seems to think its ok for diesel to mix with unleaded, so perhaps its ok?

(Next thing I know I'll be putting cooking oil in mine when the weekly budget goes into the red and if it blows up I'm going to blame you guys for it )

i always thought diesel in petrol would immediately destroy the cat which is why the fuel filler from a diesel won't go in a petrol filler neck. pity they didn't make the diesel filler triangle (eg toblerone) shape then i wouldn't have been able to put the unleaded into my diesel either. perhaps i should patent that idea then i could afford a new engine if i need one

seems like lots of you have heard about putting petrol into diesel to stop it waxing so maybe i will be ok especially if i keep topping up with new diesel every 100 miles or so to dilute it as much as poss.

still feeling sick and sweating buckets every time i think of this mistake.

It is a bit of a girlie thing to do though, you should be embarrased!

2 biggest problems here are :-
1) Diesel floats on petrol when left to settle, so on start up you may get neat'ish petrol sucked through, leading to the 2nd point.

2) Extremely hi pressure diesel pumps do not like the lack of lubricant in petrol, niether do the injectors.

Fingers crossed you get away with it.
