Guys,

Just after some quick advice. I've just put about 94p worth of unleaded in my Kia Pro Cee'd diesel and then topped it up with about £30 of normal diesel.

After have a look on the web, although not a great idea it seems that less than 10% is normally okay and will burn off. I've done about three or four miles and it seems fine.

I'm in need of reassurance wink

It'll be fine... Probably smile

Keep the tank full with diesel for a while to dilute it as much as you can. Your tank holds 53 litres, assuming you brimmed it that's only 2% petrol.

Less than a litre of petrol in a full tank is probably not going to cause any issues.

I'd keep the tank topped up with diesel for the next week or so just to be on the safe side.

You'll be fine - just keep topping up when the tank's half full for a few times and don't worry.

Far worse the other way round but I managed to put £20 worth into my Range Rover and just kept on topping up at half full for about 100 miles and no issue.

It's fine. I did the in a hire car once. €10 euro of petrol into diesel and even that was fine. Kept the tank full of diesel the whole time. It stuttered a little in the beginning but was fine by the end.

Is it? I always thought it was worse to put petrol into a diesel, as the fuel is used to lubricate the pump. Whereas diesel in a petrol engine tends to just burn off.

94p's worth? That's little more than a dribble.

I run my mower on some waste petrol with diesel in it, it tends to foul the plugs pretty regularly.

There may well be more petrol than that in the tank of the tanker that delivered it

For relatively small quantities it's harmless.

Even for a tank full, it doesn't do a great deal of damage if caught quickly. RAC/AA et al deal with loads of these on a daily basis.
