What tha ? 10w-20w-40?

[Stumpy]

Was roaming through some antique stores in Huntsville Alabama and came across this collection of Conoco motor oil. Since they are paper cans I'm guessing this stuff's 35-40 years old at least and they were claiming it was so good it could go 15,000 miles! I love the viscosity range.

I remember that oil, early 80's I believe. Yes, not sure why they had it as 10w-20w-40. Conoco also was big in the 70's having 20w20.
