Over the lasts few years the fuel distillery company's have been reformulating the fuels to have lower temp boiling point.
Because of carburated engines being thing of past and fuel injection not effected by lowered fuel temp boiling point.
I guess there must be cost savings for fuel company's in this new formulation

Because of this today's formulated fuels tend to also be less dence meaning that your float levels tend to be higher because floats sink into fuel more meaning fuel levels need to be adjusted lower to make up for this less dence fuel.
