i decided to try the performance diesels for comparision, i tried BP ultimate and shell v power.
I did a lot of motorway cruising but it was mixed up with a good dose of devon lanes......
the results are:
BP Ultimate - 46.92mpg
Shell V power - 52.10mpg
i was strange though because i was convinced the bp fuel was going to do better. It felt punchier than the shell.
I stuck to all speed limits and i used the cruise control whenever possible.
quite a difference between the two, I've now filled up on normal texaco - I will be able to use it as a reference.
I just hope John CS doesnt read this.........
