Thread: Oh ****, petrol in the D4!

Not really necessary unless its dumped a heap of fuel in the oil causing a fuel dilution issue.

But how would you average punter know. I imagine even 1% is too much

Oil sampling is the only way to know for sure. Anything over 2-2.5% I would consider excessive. Fuel dilution the issue is more the reduction in viscosity which is the problem. The other side affect is the risk of crank case explosion.

Just change the oil and then forget about it,if there are any concerns.

That would be the very least of your problems,and the $ value of the oil change would be buggar all compared with the whole job.

Sorry for the lack of updates, we've just been away camping on Bribie for the last week. So after querying LR about the fact that the misfuel device failed to activate, the response we received was that this was only there to assist and that at the end of the day it's the driver's responsibility to put the correct fuel in the tank.

So we have now had the car towed to M.R, on the assumption that what ever work needs to be done will probably be considerably cheaper with them than Austral. I have to say that Austral were very good throughout the whole process, and completely understanding when we told them we were sending the car to M.R.

Hopefully the guys at M.R will get a chance to look at it this week. Fingers crossed the damage isn't too bad.

I'll keep my fingers crossed for you Mojo.

Well $800 later, we have the D4 back on the road. M.R drained it and flushed the fuel system, new fuel filter, changed the oil, and so far no problems. Hopefully we don't get any related problems down the track, the M.R guys seemed pretty confident it would be OK.

Diesel engines only inject fuel after the compression stroke so how can the viscosity be an issue ? , different with a petrol engine as it is compressed before ignition and there for can leak past the rings onto the bores and into the sump.
Obviously the fuel lines and pump may suffer but then again they use fuel resistant hoses/seals.
