I recently refuelled my brand new diesel engine car when it was basically empty (25 miles left) and then drove away. I drove the car for about 100 miles before noticing the standard juddering that you get with some kind of contaminated fuel.
I am like 99.99% percent sure that I put diesel in the car but let's assume that I actually put petrol in. Is it possible that I could drive 100 miles in a diesel car on petrol (with a small amount of diesel remaining) without noticing? If this is possible then how likely is it?
