It would be helpful to know which "several decades" this generalization is being applied to, as well as its basis.  Thanks to Steve's book, we know exactly how many class V, X and X-3 cars UTLX acquired between 1901 and 1937.  The 10,000-gal  cars outnumbered the 8000s by about 4.5 to 1.  Even the 6000/6500-gal cars outnumbered the 8000s by about 2.5 to 1, with the latter only accounting for 12% of the total.
Given the overall size of the UTLX fleet (35,000+ cars from 1930 to 1945), I am curious to know which other fleets were sufficiently dominated by 8000-gal cars to effect the shift to a dominance of that size.  And where the supporting data can be found.
