That video is full of myths and is very basic overview
Low /mid saps oil have less additive and Zddp yes. But doesn't mean they need more expensive alternative chemistry. Additive systems now can offer similar wear performance but wil detergent being the level to pull for ash level.
Mid saps are 0.8% ash whereas most A3/B4 oils are around 1.1 for the 10TBN.
There's no need for Ashless TBN boosts since ACEA moved to 10TBn from 8TBN min for A3/B4. Not sure what he is thinks you need alternatives to zddp either
