the additive/modifier is for the LSD oil. HOGWILD is a man that follows his manual, some might say religiously. Manual says add the modifier and change every 30k. Oil manufacturer may say differently.
Just like Jiffy Lube says every 3k, Amsoil says every 15k, and Toyota says every 5k for crankcase oil changes. Jiffy Lube sells service, Amsoil sells product, and Toyota sells engines (with cars & trucks attached).
