They probably just thinned some crude with gasoline to get the viscosity right
Just kidding, but your story does make me wonder if lower viscosity fractions were getting cooked out and burned off in these blowby machines of ours. Of course, if you have one of those rare no-blowby engines, then that theory is dead
