Thread: Td5s and Petrol just dont mix!

Forgot to mention: I've done 100k's since and the Disco appears to be running sweet. I'll keep everyone updated, just in case the pump or some other component decides to throw in the towel!

I heard you mix "light" fuel with diesel to make it go better,,

maybe not in that ratio----

Soooo.......


How come you taking the grief for your wife?

Some years ago the (one and only) petrol station in town filled their ULP tank with diesel instead of the correct stuff. You should have seen the number of cars that filled up and got about 500m before dying

I'd say lucky you caught it when you did and good on you for owning up. I think a lot of others have done this and gone off to hide somewhere.

Kinda like me! Although I had mentioned it my NT ...Blockie trip report. I did it in Innaminck a couple of months ago, topped up already half a tank with 25 litres of premium unleaded before I realised what I was doing. Luckily that was before I finished filling so I hadn't started it. I paid a hefty price though, $1.95 cpl for the premium, $2.10 cpl for the diesel, $130 to drain - near on $500 for the mistake. I feel for you & hope there's no long term damage, good luck!

Never put petrol into my diesel disco, but I did throw in a crankcase load of sump oil as I was saddened to see its energy content wasted.

I hope you filtered it!! used sump oil through your injectors?? eek....

Geez well where do I start,

This has happend to a few of the machines I maintain over the years but 2 stand out for the sheer stupidity yet the sheer lack of mechanical damage.

# 1. Jacobsen GK5 greens mower, 3 cyl Kubota NA diesel, runs out of diesel on a certain inner city melbourne golf course green.

They ring me when I was in Geelong, I give then instructions on how to bleed it to get it going and so they tell me they will call me if they have any more trouble.

I get the call about 1/2 hr later, still wont go so they have dragged it off the green, this is a problem in it self as you need to resease the hydraulics to be able to move it so they have ripped up half the green in dragging it through all the fuel they have spilt while trying to bleed it.

40mins later I get there, from 100m away I could smell the ULP and here they were with the jumper leads from the bosses ute jump starting it because they had cranked the battery until dead.

I released the Hydrostat, towed it to the shed, roped off the green (which died and had to be massively reconstructed) with signs DO NOT SMOKE etc etc.

Drained the tank refilled with Diesel and bled and I couldnt even believe it.......it started.

It ran fine for another 3 years with no issues.

# 2. was basically the same machine just the update GK6, similar situation other than instead of running out, he decided to come back and fill up before he did but filled it with petrol not diesel.

Got to the other side of the course and half way through a green before it spluttered and cut out.

Same thing, drained and refilled (I was on site this time) and sure enough, it's still going, the engine seems to be the best part of that machine.

You may find that it may loosen off some gum and crap in the system but if it's running well now it should be ok.

Good on you for owning up to it, a lot of people wouldnt.

1 more comes to mind about the sump oil...

It isnt so much going through the injectors that you worry about, it's when a turbo seal goes and it gets atomized into the intake manifold and burned along with the diesel.

Problem being, while you have oil there you have no control so the revs just increase and increase until it either goes bang or it runs out of oil.
