How much petrol in a 2.25 diesel

I have been recommended to add a small amount of petrol to the mix to clear the ****e out of my 2.25 diesel, how much would be correct?

wont veggie oil help clean the crap out, out of the lines anyway?

yes, it will.

@OP
I'd use a near empty tank, and not more than 5% petrol when it's warm outside, but without loading the engine (v<30mph ; no uphill or fast acceleration).
Risks: engine knock, too hot flame, exploding burn (vs slow burning (diesel) )

Personally, I'd use veggie oil or clean engine oil (or GB oil, or anything I dont need.) I usually just dump in the tank everything I dont need, as long as it's unused... (lots of metal in used GB oil for example)
Oh, and pack a spare fuel filter!

It's veggie oil I'm cleaning out! Use it a lot!

A good batch of proper biodiesel will help clean it all, partcularly if you stick 5-10% petrol in it.

You could always chuck a bit of injector cleaner in too if you like.

Maximum 'contamination' is 20% without causing damage - so effectively, as ong as you are below that figure, you should be fine!

Lorry driver usually pop a few pounds worth of petrol in to stop mould forming on the diesel of trucks that have intermittent use.
