Petrol in a Td5?

Feb 17, 2007 5 Replies

Hi all, my wife rang me all in a panic. She had half a tank in her 90 Td5 and mistakenly put just under14 ltrs unleaded in it. Realising her mistake she then brimmed it with Diesel.



That would make about 3 gallons of petrol in about a 20 gallon? tank.



She then drove it home, a distance of around 7 miles. Seemed to run fine.



Advice so far seems to be 50/50 it will be OK or it will die.



Suggestions please. Thanks, Chris.


Bartty uttered summat worrerz funny about:

Just keep topping it up with Derv as soon as there is space in the tank to do so. I would imagine it would be fine. Diesel is often treated to a spash of petrol in the winter to help stop it gel and assist with cold starts, though modern diesel fuel tends to be a bit more sophisticated.

Agree with lee, keep topping up when possible for at least a few tankfulls.

Stick a pint of regular lube oil in the tank. This will restore the lubricity to the fuel lost by the addition of the petrol and hopefully safeguard the pump etc.

I did this last year, and posted about it on here - a Google search should show it up. Common rail diesels will tolerate petrol contamination much less well than the older type, but I think I got away with it. There have been no long-term effects, apart from a possibly slightly louder rattle at idle. Keep brimming with diesel, as others have said. I added a litre of

2-stroke oil as well, to help lubricate the pump.

My filler flap now sports the legend: It's Diesel, You Tit.
