I Recently bought a 2005 3.0 x5 diesel, previously i owned a petrol car!!

I put 14.88 ltrs of unleaded petrol, then realised i should have put in diesel!!

I then put in 69.68 ltrs of diesel - on top of the petrol - basically filled up the tank!!

Before i put in the petrol it was showing that i had 50mls to go (diesel)!

I continued my journey on the motorway

An hour later i put in a further 10.23 ltrs of diesel

Then half hour later stopped - 3 hours break

Then 1 and a half hours later i put in 16.04 ltrs of diesel

As for driving i havent felt anything - what am i supposed to feel - will i later?

Is this a cause for concern?

Did i do the right thing?

Please HELP???!!!
