Diesel running on super

not to sure about petrol in diesel but many years ago i got a little impatient waiting to fill up and drove into the next available bay and with out noticing i filled the petrol b2000 up with diesel.drained it out and all was finenew job coming so no fraser this time:-((

Hi Bud, all you need to do is drain your tank & flush your fuel lines & filters, replenish with diesel & bleed the system of the petrol including the injection pump & injector lines. Petrol will not damage your engine because it has not the hydraulic properties of diesel so if it got as far as your injection pump it doesn't get any further because the pump cannot pump it to the injectors & the engine just stops running is though it has run out of fuel. You may have to crank the donk over a few times to get the fuel to the injectors. If you just loosen a few of the lines on the injectors, crank over the engine & look for signs of diesel at the loosened injector caps, retighten then crank over a few more times till the engine starts. It may run rough for a few minutes until it gets rid of any air left in the lines. Hope this helps. CheersHave Wheels Will Travel

Did that at Rainbow Beach just to top up before going to Frazer Island. I put $20 of petrol into my HJ60. I didn't start the 4wd when I realised. Had to tow it away to nearest workshop, drain all fuel from tank - 90l then refuel.
Later found out that this was common happening on that petrol station as the
fuel pumps were not marked clearly and easily mistaken.

My uncle put nearly half a tank of super in his GQ diesel a few years ago. He drove it quite some distance and was wondering why it was running rough/smoking/gutless. After he realised what he'd done, the tank was drained and the vehicle ONLY did another 200,000 odd kays before it was traded in on a new one.... it was still running fine!

Doesn't the injector pump use the diesel as a lubricant ?

If so id think it could cause damage if left in the system.

I was led to beleive that petrol wont ignite just by compresion, so if you put it in a diesel it will only ignite after the diesel has ignited causing the cylinder to fire twice per power stroke.(no more power just rough running)
Prolonged use of petrol in diesel causes premature engine wear but a small amount left in the tank shouldnt hurt once only.
This was explained to me by a diesel mechanic mate of mine when I told him I used to tip a gallon of petrol into my diesel cruiser every time I filled up.(a trick an old truckie told me "to make em go better")

Bud.

Don't panic Bud, it will be ok, any thing under 50/50 mixture will not harm the motor, some diesel mechanics add petrol to diesel as a lazy way of cleaning the injectors,the petrol will cause the motor to run hot and this burns the carbon of the injectors, there is a well known diesel aditive for cleaning injectors and it is just un leaded with a colour added and priced at aprox $50/litre.SO just fill your tank with diesel and drive home, Eric.

Bud,

I'm chuckling at this because a few years ago my brother did the same thing in his Rocky - I had a fun evening driving out to where he was and helping him to drain the tank. We found that the diesel floated on top of the petrol in the tank, so the petrol drained out the drain plug first and after a while the consistency changed and we could tell we now had mostly diesel. So I'd leave the car sit a bit, then drain it till you get the colour change, then go fill it with diesel after that.

I'm sad to say I put 40 odd litres of unleaded in in my 90L Hj60 (diesel landcruizer) giving me a 50/50 mix. I realised what I had done and spent five minutes deciding what the pros and cons where of driving home to drain it. After driving home and draining found no problems. Engine ran just fine. I have herd somewhere that diesel filters can be damaged by petrol?? Cheers Hardy

Thanks for all the replies.
Drained the tank at the servo filled up with the right stuff and I've driven 350 km since. No Worries whatsoever. My missus is now banned from driving my ute unsupervised, but she did clean and polish it 'cos she felt so bad, so maybe im being a bit harsh.

thanks again
