wrong fuel
macc man - 28/2/10 at 10:44 AM

Feel realy stupid as I filled my deisel van with petrol instaed of deisel. Only noticed after 15 litres had gone in. After spending time and money on siphon tools which did not work, I found a solution to removal. On the fuel filter is a rubber purge bulb. By removing the inlet pipe and squeezing the bulb you can manually empty tank into suitable container. Worked very well and no apparent damage to engine. Hope this may help another numpty.

Well at least you didnt manage to put diesel into a petrol car - thats far worse (and why the nozzle is bigger on diesel pumps at the filling station)

Fill 'er up and it'll be fine

I wouldn't worry. My mate filled up his diesel van with unleaded and drove all the way from Leeds to London without a problem. Didn't want to start in the morning but a quick drain and fill up with diesel had it running just fine. Worked for years afterwards without a problem too.

Fill it up and not worry. If you didnt run it then therel be no damage.

I bet that took ages with that little primer!!!

I know a couple of people that have put petrol in a deisel car (not as much as you though). They realised and toped the rest up with deisel and their cars are still fine now.

A lot depends on the type of pump fitted, with some modern diesel engines even using bio diesel will kill the pump. Ancient diesels were much more tolerant in the type of really bad winter currently happening it used to be a truckers trick to add a little petrol or kerosene to the tank to prevent the fuel waxing and blocking the filter. Adding petrol really wasn't a good idea because it could turn the fuel tank into a potential bomb.

The reason why petrol nozzles are smaller is actually to prevent unleaded being used in modern cat equipped cars.

Some modern diesels can detect a change in pressure if petrol is in the diesel and shuts them down but they can only be reset by the main dealer software

You sure it's that way round ?

Diesel engines rely on the fuel to lubricate the high pressure pump, and injectors.

A petrol engine will just stop and potentially shag the cat. The engine itself
should survive.

think he means that a diesel will run on a right mix of fuels, whereas a petrol engine would be upset by small amounts of contamination.

Diesel in a petrol tank can have long term effects that don't show up for months.

Petrol in a diesel can kill the fuel pump and injectors on modern cars.

I did it myself fortunately was in RAC and about 50 yards from dealer and didnt start the engine, so the RAC guy pushed it to the dealer who drained the tank and checked everything out.

They had a guy in the month previous who had done the same but "filled 'er up" and carried on. Withing 200 miles his engine was shagged and needed a rebuild cost him £1600 at dealer rates. And I know this isnt just the dealer trying to scare me as I know the mechanic that worked on the car

my parents have done this serveral times with the 405 they had.

Everytime it would start to run really badly then not restart. They just got it towed home and used that primer bulb to remove the petrol.

I used to like it as would get the diesel tainted petrol for my 106!

But then the engine in the 405 like my work van is old tech.
