Damn...we used to jump up and down when we got Sunoco Blue,
aka Sunoco 260, back in the early '60s on Woodward Ave in
the MotorCity, for less than a Qtr a gallon!
It had so much freakin lead in it, even my bent to the nines,
heavily breathed on 283 Chevy V8, punched to ~300+, ran
like a champ.
Ah, the good old days...
I'm sure you donated the mistaken "diff" to some good charity, Weasel?!
