Hi all

My car has just been towed home as my wife has put diesel into the
petrol tank. Needless to say that the car soon stop going.

What damage is likely to have been done and what can I do to sort the
problem out? It's a petrol fuel injected Nissan Pulsar 1.5L.

I reckon I need to drain the petrol tank, refill with petrol and get a
new fuel filter. Will I be OK?

Thanks

How do you manage to accidentally fill your car with diesel, they are
clearly labeled, in fact you have to go out of your way to get to the
diesel pump and preform the tricky task of holding in a second lever.

Shouldn't be any lasting damage. You're on the right track with your ideas.
Drain the tank, refill with petrol. Find the fuel pump relay bypass and get
the fuel pump running (without cranking the engine) to flush the diesel out
of the lines. The start it and go for a drive. Leave the fuel filter until
after it's running ok again.

A trick that school boys began playing at one of our local garages was to
put a petrol dispensing nozzle in the deisel holder so when the next diesel
customer turned up they were likely to squirt a gobfull of petrol into their
tank. A gob full if they were observant enough to smell the petrol, or a
tank full if they weren't.

The company modified the dispenser, but having been caught once I always
check that the right nozzle comes from the right pump.

Shouldnt be any serious problems: you are lucky that you don't have a
diesel vehicle into which petrol was put...

Thanks to all that replied.

I have drained the fuel tank, drained any pipes, cleaned spark plugs,
and will fit a new fuel filter after a few days of running. All
appears to be well.

Phew !!!!


Thanks again guys.

My neighbours wife did that and it wasn't too bad. It took a while to
come clean and smoked and choked a bit for a little while but it runs
great now.

The ignition point of petrol is lower than diesel, because of this
preignition damage has probably been done to the cylinders of the engine.

There are two stations around here that have diesel and petrol on the
same bowser - 91 octane petrol on one side, diesel on the other. It
wouldn't be hard to get as far as picking up the wrong nozzle. Not
having actually done so myself, I couldn't comment on whether the
difference in nozzles should be obvious.

There's a guy in Auckland who specialises in removing the "wrong fuel"
from your vehicle, and according to the Listener he's doing good
business - "Mr Suckie Moto".

What second lever? Run both petrol and a diesel car and the pump delivery
nozzels are the same animal. Fill at a large number od services too. Diesel
coded Black while petrol either Green or Red.

A diesel too long on petrol will see a damaged fuel pump. Diesel is a very
fine oil and the pump that produces the high pressures relies on its
lubrication from this oil....

As a younger lad my mate had a '64 Chev V8 that was way too thirsty for his
wallet but he got away with putting a mix of petrol and diesel through it.
Sometimes there was a bit too much diesel and man that car smoked but it
kept running for years and produced way more power and acceleration than the
crappy old Austin Cambridge 4 banger that my parents forced me to get round
in.

That may have had to do with the four extra cylinders than the fuel mix.

Petrol has a mugh higher octane than diesel. It shouldn't cause
preignition in a diesel engine.

Octane is an additive that is not added to diesel, as far as I am aware.
Thus, octane ratings are probably not relevant to diesel.

Octane isn't added to petrol either, it is just an equivalent standard
that the fuel is measured against. Diesel uses another equivalent,
however on the same scale as petrol, deisel has an octane rating of
approx 15. The reason you don't get pre-ignition with deisel, is that
there is no fuel in the cylinder during the compression stroke, it is
injected into the cylinder at the top of the stroke.

If its diesel into a pertol all you gota do is drain it. Not just the tank
but the engine as well. As the fuel will need to be replaced from the carb.
There will be no damage since diesel has less combustion than petrol so will
not harm the engine. Basically the engine just wont go as deisel needt
compression to explode the piston and pertol needs ingnition from the spark
plug to fire it.

Want to hear a story. I pulled iunto a petrol station in Mt Wellington.
Said to the guy, 40 bucks worth of 96 please. Guy said, 96 ? I said yup.
Pointed to the sticker on the cap. "Use only 96 octaine". Cool he says.
Went to the counter to hand over my 40 bucks. The guy putting the fuel into
my car walked up to me and said, ehh, the red car is yours aye. I said yup.
He says, Um..... I think I made a mistake. I said what's that. I think I
just put diesel into your car. I pointed out that he had asked what fuel.
I showed him the sticker saying 96 octain and you STILL put the wrong fuel
in !!!???. Anyway, manager paid the bill and arranged for clearing out the
tank and engine.

I dunno. Just cant get the staff these days I guess. lol

Diesel will not ignite with a spark plug. its needs compression greater
than that of a petrol engine to force the fuel to explode. well, thats my
understanding from the guys that put the wrong fuel in my car. And I might
point out, it wasnt me that put the fuel in. See my other post

Not necessarily as you say. The design of the diesel engine is
compression ignition engine, using compressed air to ignite the fuel when
it is injected into the cylinder.

In an ordinary petrol engine, the petrol/air mix is compressed first
prior to the spark plug injection. It must not ignite during this
compression cycle prior to the spark plug firing. Raising the octane
value of the fuel means it can be compressed more without preignition.

Different ideas were used to develop the two engine types, they operate
in completely different ways so straight comparisons are meaningless.

Same as comparing a two stroke petrol engine to two stroke diesel, they
are radically different in design...

No matter tho. the end result is that once the tank and the fuel line is
drained and replaced with pertol then there will be no problems.
