A Cooking Oil for the Ages

I’m not sure why, but I kinda wanna head to this here restaurant:

Back in 1912, the late Elmer “Doc” Dyer opened his own cafe and began to develop a secret cooking process for the uniquely delicious world famous burgers we still serve here today on Beale Street.

Legend has it that the “secret” was Doc Dyer’s ageless cooking grease. This famous grease , strained daily, has continued to produce our juicy Dyer’s Burgers for almost a century now.

Are they saying that the oil has not been changed since 1912??? And that they deep fry their burgers in said oil??? Color me intrigued (and color my doctor abhorred).
