I did a fuel change and during it was concerned that I may have put diesel in my petrol car because it wasn't clear which pipe was which. However the handle was green and said unleaded so I guess it was petrol I put in.
Straight after starting up I noticed the car had become quieter and within a few minutes of driving the engine cut out and stopped. however on cranking again it did start up and I was able to drive 8 miles back without stopping although car does seem quieter than before.
In the morning before this journey battery had gone from being idle in cold and I jumped started it so maybe that had something to do with it?
However as I was confused as to what I was putting in and only after fueling did the engine sound quieter and cut out, I'm wondering what the cause might have been?
Since I am in doubt what should I do?
