Is it just my imagination, or is there a difference between the energy output of french diesel fuel and its british counterpart.? Have just returned from trip across channel and of course filled up over there to come home. Now that I've used that tankful and filled up again with british diesel I seem to notice that the top speed on a familiar dual carrigeway is around 5 mph less.
Can it be that "our" fuel " is less combustible? Do we have additives here which in some way limit the performance, or is it all just imagination on my part?
I'd l;ove to know if anyone else has experienced "la difference"
go well
