If your engine was pinking it would still have been pinking after you changed the fuel as it has nothing to do with the fuel quality. If the engine was hesitating it was most likely to be down to fuel starvation caused by some kind of blockage.  Most ‘bad fuel’ incidents which miraculously cure after changing the fuel are down to crap in the bottom of your fuel tank. 😉 Share this post Link to post Share on other sites Share this content via...

Plenty of stories in the news does not equate to plenty of occurrences in real life.  The biggest contaminant in petrol is water, and that is usually in such tiny amounts that it will be either burned or trapped in the filter.

As I said earlier, it is most likely contamination from your own fuel tank. What did the petrol station say when you went back?
