Appreciate the straight 'skinney' for a change!
To bad MBZ wouldn't send 'em here, as we've had that June 2006 Federally required fuel available now in CA for more than one year.
I actually prefer regular CARB
fuel to the ARCO ECD-1
because it has more power (BTUs) and will produce slightly better fuel economy. Something that everyone will have to face up to shortly!
My 'old' style motor doesn't seem to care what it is in its tank, as it runs very well on anything and everything including B-20 (Biotane mixed with the ECD-1), but on that expensive mix, it doesn't get nearly the fuel economy that is produced when using good old straight CARB Unifuel.
Thanks for setting everyone straight.
