During the cv19 gas fiasco my premium only VW got the one tablet octane booster with 87... never missed a beat and was $2 a tank as opposed to $20 plus.. I put 45k miles on it with one in every tank.
The owner is no nonsense and will give you detailed answers. Not a snake oil salesman
I use the basic fuel system tab in my turbo about every third tank as its a 87 octane machine and not a 91 or 93
