Mitsubishi Repair: Accidentally filled diesel in gas tank, mitsubishi gallant 2003, dark smoke

Question
Yesterday , i picked up the wrong pump while fuelling and pumped in 4 litres of diesel accidentally in my Mitsubishi Gallant 2003. I panicked and later topped it with another 7 litres of petrol and drove 25 miles back home. The car sttutered a bit but has not given me trouble so far.What should i do ? Will diesel do damage to my Galant ?

Answer
Johny,
You should be ok since you only put in 4 litres of the diesel.  Your car may run a little rough, and you may see dark smoke coming from your exhaust.  The diesel will not burn like regular petrol and has the potential of damaging sensitive emissions components, though you'd be warned if this was occurring by your check engine light.  But if you want to be safe, you can drain your fuel tank and refill it with fresh petrol.
Good luck!
