Alan, Redditch – Diesel Mini
Hi Fuel Medic,
Can you solve a mystery for me please? My diesel Mini is playing up, it’s having the occasional judder, is a bit slow starting and doesn’t feel like it did a few weeks ago. My suspicion is, my girlfriend used it a week or so ago, to impress one of her mates on a shopping trip. She’s obviously put a bit of fuel in to top it up to where it was when she took it, I reckon she might have put unleaded into it! Is there anyway to tell? I’ve asked her whether she could have put the wrong fuel in it but she’s adamant she hasn’t, her own car is unleaded which makes me think she’s done what she always does when filling up. Any thoughts?
