I've got a small turbo car with a stage one chip and stainless exhaust. I normally use Shell Optimax / V-Power but at the weekend I couldn't find a Shell garage where I was so I filled up with BP Ultimate. It wasn't cheap at 102.9P a litre but the performance and fuel economy does seem a little better than with Shell.

So what fuel do you use / prefer? And why?

Opinions and commments please.
