Thread: Diesel hilux with 10L petrol in it?

First off petrol isn't a lubricant like diesel and the tolerances in the fuel system can't handle the petrol washing the surfaces. Potential for disaster there.
Then secondly, the emissions systems when petrol is burnt will overheat and melt also causing catastrophic damage.

In the even of petrol being accidentally put into the tank, depending on how much, I would either suck out what you could from the tank disconnect the fuel line to the filter and suck it thru using a small electric pump or pressurize tank with air and push it through.
Put 1L of 2stroke oil in tank then fill tank with diesel.

If you have only put a few liters in, again put 1L of 2stroke oil in the fill to max with diesel.

As a hint, if the vehicle still has NVW whatever you do don't tell them you've done all that. Run a couple tanks of diesel thru then if its a problem take it in to them.
If you let them know you've put the incorrect fuel in, they will void your warranty entirely.
So the least they know the better.

If anyone has put AdBlue into the fuel system however that is another totally different thing. That crap is corrosive as hell.
Whatever you do DO NOT ever run it with AdBlue in it. Get the fuel system drained and the tank removed and cleaned out!

Thx, that lines up with what I found on the research. He apparently put "less than 10L in, based on less than 1/2 a 20L fuel can - but say 10L to be safe". How much petrol on a full tank of diesel in these things would be not likely to cause damage? Based on a 70L tank, and the internet recommendation of less than 5% as a safe max that lines up as 3.5L of petrol - would that be your thoughts @cambo?
