For those of you with performance diesel cars, who like to experiment with 'premium fuels'...
Just a heads-up to report that I gave Texaco's version of premium diesel, their 'Supreme', and having used it exclusively now for a few weeks, I reckon it's better than either of the main options, Shell V-Power or BP Ultimate. In the Brabster, it gives more 'poke' and the engine seems to run quieter and more smoothly.
If you're curious, maybe give it a go, if you've got a Texaco station near you!
