Oils of old didn't have the additives that modern oils have. Engines were dirtier. Hell, non-roller cams had to "wear-in", and in doing so, introduced metal into the oil. Times have changed. Save your money for mods. Your oil won't mind.

We have these amazing guys called "engineers" who actually do math and science and crazy things like that to determine when to do oil changes. If you ask me, it's the devil's work!
