Well, that seems to be mostly a marketing piece, which in of itself isn't bad. But beyond that, it points out that old classics are the ones affected - not anything recent. But I get your point, Venn diagrams or not. The bottom line is that concern for corrosion from "dry" gas is unwarranted in anything modern, correct?
The one thing I am still stuck on though is the vague need for "lubricity" in gasoline and how that is apparently missing from a gasoline/ethanol blend. What does lubricity do again and why is it important?
