I don't want to start (yet another?) fuel war in here, but I do have a question. I can't find anything using Google so Motors it is. 
I live sandwiched between a Shell, a Total and a Murco fuel station. I've always driven diesels and on my last car (HDi) I found that Murco offered the best 'experience'. The car always seemed to deliver better MPG and had a more willing throttle (more 'pull' if you will). Switching back to Shell didn't affect economy too badly but power delivery was definitely down. I've avoided Total out of principle for years, so I can't really comment on those.
However, Murco isn't really a big brand per se and you don't see many of them. My question is, how good exactly is it? I don't mean "Which is the best fuel to use?", but rather "Where does Murco sit in the scale of supply?".
Are they a 'premium'/branded fuel comparable to Shell, BP etc or are they more your budget supermarket bare minimum type? Their derv certainly seems denser and richer than the smoky Tesco pap, in fact it smells rather suspiciously like BP Ultimate. In other words, it 'feels' like a premium fuel and the car does well on it - but is it something I should be using long term or am I better off sticking to Shell so my injectors don't foul up and die inside two years?
I know this is somewhat of an abstract question, but hopefully you can get what I'm trying to ask. TIA.
